  • Displaying NON-ASCII Characters using HttpClient

    - by Abdullah Gheith
    So, i am using this code to get the whole HTML of a website. But i dont seem to get non-ascii characters with me. all i get is diamonds with question mark. characters like this: å, appears like this: ? I doubt its because of the charset, what could it then be? Log.e("HTML", "henter htmlen.."); String url = "http://beep.tv2.dk"; HttpClient client = new DefaultHttpClient(); client.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); client.getParams().setParameter(CoreProtocolPNames.HTTP_ELEMENT_CHARSET, "UTF-8"); HttpGet request = new HttpGet(url); HttpResponse response = client.execute(request); Header h = HeaderValueFormatter response.addHeader(header) String html = ""; InputStream in = response.getEntity().getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); StringBuilder str = new StringBuilder(); String line = null; while((line = reader.readLine()) != null) { str.append(line); } in.close(); //b = false; html = str.toString();

  • Stuck in Infinite Loop while PostInvalidating

    - by Nicholas Roge
    I'm trying to test something, however, the loop I'm using keeps getting stuck while running. It's just a basic lock thread while doing something else before continuing kind of loop. I've double checked that I'm locking AND unlocking the variable I'm using, but regardless it's still stuck in the loop. Here are the segments of code I have that cause the problem: ActualGame.java: Thread thread=new Thread("Dialogue Thread"){ @Override public void run(){ Timer fireTimer=new Timer(); int arrowSequence=0; gameHandler.setOnTouchListener( new OnTouchListener(){ @Override public boolean onTouch(View v, MotionEvent me) { //Do something. if(!gameHandler.fireTimer.getActive()){ exitLoop=true; } return false; } } ); while(!exitLoop){ while(fireTimer.getActive()||!gameHandler.drawn); c.drawBitmap(SpriteSheet.createSingleBitmap(getResources(), R.drawable.dialogue_box,240,48),-48,0,null); c.drawBitmap(SpriteSheet.createSingleBitmap(getResources(),R.drawable.dialogue_continuearrow,32,16,8,16,arrowSequence,0),-16,8,null); gameHandler.drawn=false; gameHandler.postInvalidate(); if(arrowSequence+1==4){ arrowSequence=0; exitLoop=true; }else{ arrowSequence++; } fireTimer.startWait(100); } gameHandler.setOnTouchListener(gameHandler.defaultOnTouchListener); } }; thread.run(); And the onDraw method of GameHandler: canvas.scale(scale,scale); canvas.translate(((screenWidth/2)-((terrainWidth*scale)/2))/scale,((screenHeight/2)-((terrainHeight*scale)/2))/scale); canvas.drawColor(Color.BLACK); for(int layer=0;layer(less than)tiles.length;layer++){ if(layer==playerLayer){ canvas.drawBitmap(playerSprite.getCurrentSprite(), playerSprite.getPixelLocationX(), playerSprite.getPixelLocationY(), null); continue; } for(int y=0;y(less than)tiles[layer].length;y++){ for(int x=0;x(less than)tiles[layer][y].length;x++){ if(layer==0&&tiles[layer][y][x]==null){ tiles[layer][y][x]=nullTile; } if(tiles[layer][y][x]!=null){ runningFromTileEvent=false; canvas.drawBitmap(tiles[layer][y][x].associatedSprite.getCurrentSprite(),x*tiles[layer][y][x].associatedSprite.spriteWidth,y*tiles[layer][y][x].associatedSprite.spriteHeight,null); } } } } for(int i=0;i(less than)canvasEvents.size();i++){ if(canvasEvents.elementAt(i).condition(this)){ canvasEvents.elementAt(i).run(canvas,this); } } Log.e("JapaneseTutor","Got here.[1]"); drawn=true; Log.e("JapaneseTutor","Got here.[2]"); If you need to see the Timer class, or the full length of the GameHandler or ActualGame classes, just let me know.

  • Runnable to be run every second only runs once in Fragment onCreateView()

    - by jul
    I'm trying to update the time in a TextView with a Runnable supposed to be run every second. The Runnable is started from a Fragment's onCreateView(), but it's only executed once. Anybody can help? Thanks public class MyFragment extends Fragment { Calendar mCalendar; private Runnable mTicker; private Handler mHandler; TextView mClock; String mFormat; private boolean mClockStopped = false; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { RelativeLayout view = (RelativeLayout) inflater.inflate(R.layout.meteo_widget, container, false); /* * Clock (from DigitalClock widget source) */ mClock = (TextView) view.findViewById(R.id.clock); mCalendar = Calendar.getInstance(); mHandler = new Handler(); mTicker = new Runnable() { public void run() { if(mClockStopped) return; mCalendar.setTimeInMillis(System.currentTimeMillis()); mClock.setText(DateFormat.format("hh:mm:ss", mCalendar)); mClock.invalidate(); long now = SystemClock.uptimeMillis(); long next = now + (1000 - now % 1000); mHandler.postAtTime(mTicker, next); } }; mTicker.run(); return view; } @Override public void onResume() { super.onResume(); mClockStopped = true; } @Override public void onPause() { mClockStopped = false; super.onPause(); } }

  • Inserting an element into a sorted list

    - by Russell Cargill
    Ok I'm using getSharedPreferences to store my high score but before I fill it up I wanted to sort the scores into ascending order via and array, but if it finds a Score less than it in the first pos then it wont check the rest for the smallest? //function to add score to array and sort it public void addscoretoarray(int mScore){ for(int pos = 0; pos< score.length; pos++){ if(score[pos] > mScore){ //do nothing }else { //Add the score into that position score[pos] = mScore; break; } } sortArray(score); } should I call sortArray() before and after the loop to fix this problem or is there a better method to achive the same results? I should also mention that the sortArray(score) funtion is just calling Arrays.sort(score) where score is an array of mScore

  • HTTPS with Self-Signed Certificate Issues... Solution or better way?

    - by stormin986
    All I need to do is download some basic text-based and image files from a web server that has a self-signed SSL certificate. I have been trying to figure out how to use HttpClient to do this, but getting the SSL to work is a nightmare that seems to be way too much trouble for such a simple task. Is there a better way to perform these file downloads? Perhaps through a WebView or Browser feature? Reinventing the wheel of making a simple HTTPS GET request is a major pain, and is significantly holding up my development schedule. ** Updated title to more accurately reflect question / solution **

  • Pass a Message From Thread to Update UI

    - by Jay Dee
    Ive created a new thread for a file browser. The thread reads the contents of a directory. What I want to do is update the UI thread to draw a graphical representation of the files and folders. I know I can't update the UI from within a new thread so what I want to do is: whilst the file scanning thread iterates through a directories files and folders pass a file path string back to the UI thread. The handler in the UI thread then draws the graphical representation of the file passed back. public class New_Project extends Activity implements Runnable { private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { Log.d("New Thread","Proccess Complete."); Intent intent = new Intent(); setResult(RESULT_OK, intent); finish(); } }; public void getFiles(){ //if (!XMLEFunctions.canReadExternal(this)) return; pd = ProgressDialog.show(this, "Reading Directory.", "Please Wait...", true, false); Log.d("New Thread","Called"); Thread thread = new Thread(this); thread.start(); } public void run() { Log.d("New Thread","Reading Files"); getFiles(); handler.sendEmptyMessage(0); } public void getFiles() { for (int i=0;i<=allFiles.length-1;i++){ //I WANT TO PASS THE FILE PATH BACK TU A HANDLER IN THE UI //SO IT CAN BE DRAWN. **passFilePathBackToBeDrawn(allFiles[i].toString());** } } }

  • Why is my onSharedPreferenceChangeListener being called multiple times when I change a pref.

    - by brockoli
    I've written an app with 3 tabs. Each tab has the same list view with different data sources. I have setup SharedPreferences in the tabhost activity, but I put my onSharedPreferenceChangeListener method in my listactivity. When I change a preference, my listener gets called and it updates my database. This is all working. However, if I change the data in tab 1, it calls my listener once. If I change the data for tab 2 it calls it twice and if I change the data in tab 3 it calls it three times. Any idea why it works this way? I guess I could setup my shared prefs in my listactivity and that might avoid the issue, but I'm curious why my listener is called multiple times if it's in a different tab. brockoli

  • ImageAdapter and ListView (java.lang.OutOfMemoryError: bitmap size exceeds VM budget)

    - by theDude
    Hi, I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds. I tried clearing cache, canceling cache, etc. - nothing helped. I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them. Any help will be appreciated, Tnx.

  • Is it ok to perform DB operation on UI thread?

    - by user648462
    I am using a database to persist the state of a search form. I am using the onPause method to persist the data and the onResume method to restore it. My opinion is that restoring and persisting state should be a blocking operation so I plan to perform the database operations on the UI thread. I know this is generally discouraged but the operations should be quick and I think if they were done asynchronously they could lead to inconsistent UI behaviour. Any advice

  • Androids ExpandableListView - where to put the button listener for buttons that are children

    - by CommonKnowledge
    I have been playing around a lot with the ExpandableListView and I cannot figure out where to add the button listeners for the button that will be the children in the view. I did manage to get a button listener working that uses getChildView() below, but it seems to be the same listener for all the buttons. The best case scenario is that I would be able to implement the button listeners in the class that instantiates the ExpandableListAdapter class, and not have to put the listeners in the actual ExpandableListAdapter class. At this point I don't even know if that is possible I have been experimenting with this tutorial/code: HERE getChildView() @Override public View getChildView(int set_new, int child_position, boolean view, View view1, ViewGroup view_group1) { ChildHolder childHolder; if (view1 == null) { view1 = LayoutInflater.from(info_context).inflate(R.layout.list_group_item_lv, null); childHolder = new ChildHolder(); childHolder.section_btn = (Button)view1.findViewById(R.id.item_title); view1.setTag(childHolder); childHolder.section_btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(info_context, "button pushed", Toast.LENGTH_SHORT).show(); } }); }else { childHolder = (ChildHolder) view1.getTag(); } childHolder.section_btn.setText(children_collection.get(set_new).GroupItemCollection.get(child_position).section); Typeface tf = Typeface.createFromAsset(info_context.getAssets(), "fonts/AGENCYR.TTF"); childHolder.section_btn.setTypeface(tf); return view1; } Any help would be much appreciated. Thank you and I will be standing by.

  • How can you tell if an activities state is stored?

    - by Joren
    I have an activity which pulls some JSON from my server, and then uses it to draw a list. That list launches further activities. My problem is that I can't figure out a way to tell if the activity is still alive when you go back to it, so I end up re-querying my JSON from the server and redrawing the list every time the user goes back to the activity. How can I tell if my activity is still alive so I can skip the redraw?

  • Dismiss a custom dialog?

    - by YaW
    Hi, I'm trying to make a custom dialog to show a view in this dialog. This is the Builder code: //Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.custom_dialog_simple, (ViewGroup) findViewById(R.id.rlDialogSimple)); //Change Text and on click TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple); tvDialogSimple.setText(R.string.avisoComprobar); Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple); btDialogSimple.setOnClickListener(new OnClickListener() { public void onClick(View v) { //Do some stuff //Here i want to close the dialog } }); AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this); builder.setView(layout); AlertDialog alert = builder.create(); alert.show(); So, i want to dismiss the dialog in the onClick of btDialogSimple. How i can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so i don't want to make a builder.setPositiveButton. Any ideas?

  • Is displayMetrix xdpi and ydpi accurate?

    - by oddvark
    Can the xdpi and ydpi settings be relied upon to accurately represent the physical pixels in once inch of screen space? I need this to be accurate for some display code I'm writing. I realize the documention says that this is the case, but I need to know if individual handsets get this right MOST OF THE TIME. I know I can alternately use "densitiy" which will give me 120, 160, 240 steps of DPI, but an exact dpi would be much better. Thanks!

  • Reading data from database and binding them to custom ListView

    - by N.K.
    I try to read data from a database i have made and to show some of the data in a row at a custom ListView. I can not understand what is my mistake. This is my code: public class EsodaMainActivity extends Activity { public static final String ROW_ID = "row_id"; //Intent extra key private ListView esodaListView; // the ListActivitys ListView private SimpleCursorAdapter esodaAdapter; // adapter for ListView DatabaseConnector databaseConnector = new DatabaseConnector(EsodaMainActivity.this); // called when the activity is first created @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_esoda_main); esodaListView = (ListView)findViewById(R.id.esodaList); esodaListView.setOnItemClickListener(viewEsodaListener); databaseConnector.open(); //Cursor cursor= databaseConnector.query("esoda", new String[] // {"name", "amount"}, null,null,null); Cursor cursor=databaseConnector.getAllEsoda(); startManagingCursor(cursor); // map each esoda to a TextView in the ListView layout // The desired columns to be bound String[] from = new String[] {"name","amount"}; // built an String array named "from" //The XML defined views which the data will be bound to int[] to = new int[] { R.id.esodaTextView, R.id.amountTextView}; // built an int array named "to" // EsodaMainActivity.this = The context in which the ListView is running // R.layout.esoda_list_item = Id of the layout that is used to display each item in ListView // null = // from = String array containing the column names to display // to = Int array containing the column names to display esodaAdapter = new SimpleCursorAdapter (this, R.layout.esoda_list_item, cursor, from, to); esodaListView.setAdapter(esodaAdapter); // set esodaView's adapter } // end of onCreate method @Override protected void onResume() { super.onResume(); // call super's onResume method // create new GetEsodaTask and execute it // GetEsodaTask is an AsyncTask object new GetEsodaTask().execute((Object[]) null); } // end of onResume method // onStop method is executed when the Activity is no longer visible to the user @Override protected void onStop() { Cursor cursor= esodaAdapter.getCursor(); // gets current cursor from esodaAdapter if (cursor != null) cursor.deactivate(); // deactivate cursor esodaAdapter.changeCursor(null); // adapter now has no cursor (removes the cursor from the CursorAdapter) super.onStop(); } // end of onStop method // this class performs db query outside the GUI private class GetEsodaTask extends AsyncTask<Object, Object, Cursor> { // we create a new DatabaseConnector obj // EsodaMainActivity.this = Context DatabaseConnector databaseConnector = new DatabaseConnector(EsodaMainActivity.this); // perform the db access @Override protected Cursor doInBackground(Object... params) { databaseConnector.open(); // get a cursor containing call esoda return databaseConnector.getAllEsoda(); // the cursor returned by getAllContacts() is passed to method onPostExecute() } // end of doInBackground method // here we use the cursor returned from the doInBackground() method @Override protected void onPostExecute(Cursor result) { esodaAdapter.changeCursor(result); // set the adapter's Cursor databaseConnector.close(); } // end of onPostExecute() method } // end of GetEsodaTask class // creates the Activity's menu from a menu resource XML file @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.esoda_menu, menu); // inflates(eµf?s?) esodamainactivity_menu.xml to the Options menu return true; } // end of onCreateOptionsMenu() method //handles choice from options menu - is executed when the user touches a MenuItem @Override public boolean onOptionsItemSelected(MenuItem item) { // creates a new Intent to launch the AddEditEsoda Activity // EsodaMainActivity.this = Context from which the Activity will be launched // AddEditEsoda.class = target Activity Intent addNewEsoda = new Intent(EsodaMainActivity.this, AddEditEsoda.class); startActivity(addNewEsoda); return super.onOptionsItemSelected(item); } // end of method onPtionsItemSelected() // event listener that responds to the user touching a esoda's name in the ListView OnItemClickListener viewEsodaListener = new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // create an intent to launch the ViewEsoda Activity Intent viewEsoda = new Intent(EsodaMainActivity.this, ViewEsoda.class); // pass the selected esoda's row ID as an extra with the Intent viewEsoda.putExtra(ROW_ID, arg3); startActivity(viewEsoda); // start viewEsoda.class Activity } // end of onItemClick() method }; // end of viewEsodaListener } // end of EsodaMainActivity class The statement: Cursor cursor=databaseConnector.getAllEsoda(); queries all data (columns) From the data I want to show at my custom ListView 2 of them: "name" and "amount".

  • Handling Application Logic in Multiple AsyncTask onPostExecute()s

    - by stormin986
    I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. The only way I can find that this is possible is if both AsyncTasks' onPostExecute() executed SO simultaneously that they were virtually running the same lines at the same time, since I set the 'itemXdownloaded' flag to true right before I check for both and call startActivity(). But this is happening enough that it's very hard for me to believe that both downloads are finishing precisely at the same time and having their onPostExecute()s so close together... Any thoughts on what could be going on here? General gist of code (details removed, ignore any syntactical errors I may have edited in): // In onPostExecute() switch (downloadID) { case DL1: dl1complete = true; break; case DL2: dl2complete = true; break; case DL3: dl3complete = true; break; } // If 1 and 2 are done, move on (DL3 still going in background) if ( downloadID != DL3 && dl1complete && dl2complete) { ParentClass.this.startActivity(new Intent(ParentClass.this, NextActivity.class)); }
