  • Android app crashes when I change the default xml layout file to another

    - by mib1413456
    I am currently just starting to learn android development and have created a basic "Hello world" app that uses "activity_main.xml" for the default layout. I tried to create a new layout xml file called "new_layout.xml" with a text view, a text field and a button and did the following changes in the MainActivity.java file: setContentView(R.layout.new_layout); I did nothing else expect for adding a new_layout.xml in the res/layout folder, I have tried restarting and cleaning the project but nothing. Below is my activity_main.xml file, new_layout.xml file and MainActivity.java activity_main.xml: <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="org.example.androidsdk.demo.MainActivity" tools:ignore="MergeRootFrame" /> new_layout.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextView" /> <EditText android:id="@+id/editText1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:ems="10" > <requestFocus /> </EditText> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /> MainActivity.java file package org.example.androidsdk.demo; import android.app.Activity; import android.app.ActionBar; import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.ViewGroup; import android.os.Build; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.new_layout); if (savedInstanceState == null) { getFragmentManager().beginTransaction() .add(R.id.container, new PlaceholderFragment()) .commit(); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here.

  • Android (Milestone/Droid): View.OnKeyListener not working correctly?

    - by Ice09
    I am using a simple EditText and register an View.OnKeyListener. Some GUI changes should happen (fading in/out of views) when certain conditions for the EditView text apply. In the emulator, this works as expected. On the Motorola Droid/Milestone, the listener does not work, only after pressing DEL, the listener is called the first time and always afterwards when activating the number input, the listener works correctly Note: I deactivated the suggestions with TYPE_TEXT_FLAG_NO_SUGGESTIONS and used the IME action IME_ACTION_GO to have a workaround for this (otherwise the user could not "start" a request).

  • why custom state won't work with compound drawable?

    - by schwiz
    Hello I am trying to make a password registration widget that will show a little checkbox in the textbox when both password boxes match. I decided to go about this by extending EditText to implement a valid and an empty state and then just use a state-list drawable to handle everything else. I followed the same method that the CompoundButton uses to add a custom state and everything seems to be right but the image will never change no matter what the state is (custom state or even state_focused etc) Is there some reason that the compound drawables of a TextView wouldn't work as a state-list drawable? Or, am I doing something wrong? Here is attrs.xml <resources> <declare-styleable name="ValidyState"> <attr name="state_valid" format="boolean"/> <attr name="state_has_text" format="boolean"/> </declare-styleable> </resources> my selector <selector xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res/com.schwiz.test"> <item android:drawable="@drawable/emptyspace" app:state_has_text="false"/> <item android:drawable="@drawable/ic_valid" app:state_valid="true" app:state_has_text="true"/> <item android:drawable="@drawable/ic_invalid" app:state_valid="false" app:state_has_text="true"/> </selector> and in my overridden EditText class private static final int[] VALID_STATE_SET = { R.attr.state_valid }; private static final int[] HASTEXT_STATE_SET = { R.attr.state_has_text }; ... private void refreshDrawables(){ Drawable[] drawables = getCompoundDrawables(); for(int i = 0; i < drawables.length; i++){ if(drawables[i] != null) { drawables[i].setState(getDrawableState()); } } invalidate(); } @Override protected void drawableStateChanged() { super.drawableStateChanged(); refreshDrawables(); } @Override protected int[] onCreateDrawableState(int extraSpace) { final int[] drawableState = super.onCreateDrawableState(extraSpace + 2); if(hasText){ mergeDrawableStates(drawableState, HASTEXT_STATE_SET); } if(isValid){ mergeDrawableStates(drawableState, VALID_STATE_SET); } return drawableState; }

  • how to hook key event.

    - by backspace7
    I'd like to limit the text length of EditText widget, And if user type more charactes than the limited length, I want to show a kind of warning popup, however I can't show popup. The problem is that we can't show popup while typing, Probably, many people think a way of utilizing OnKeyListener or OnKeyDown. But, when the word is composing, nothing come into OnKeyListener or OnKeyDown, So, we can't show popup when we want to. Is there anyone who have smart idea to solve this problem?

  • Fetching data (responsebody) with a HttpClient in an AsyncTask and returning the data outside the As

    - by Peter Warbo
    Basically I'm wondering how I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results. What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content). This is what my code looks like simpliefied with the most important parts (I think). public class activity extends Activity { private String responseBody; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initControls(); } public void initControls() { fieldSearch = (EditText) findViewById(R.id.EditText01); buttonSearch = (Button)findViewById(R.id.Button01); buttonSearch.setOnClickListener(new Button.OnClickListener() { public void onClick (View v){ search(); }}); } public void grabURL(String url) { new GrabURL().execute(url); } private class GrabURL extends AsyncTask<String, Void, String> { private final HttpClient client = new DefaultHttpClient(); private String content; private boolean error = false; private ProgressDialog dialog = new ProgressDialog(activity.this); protected void onPreExecute() { dialog.setMessage("Getting your data... Please wait..."); dialog.show(); } protected String doInBackground(String... urls) { try { HttpGet httpget = new HttpGet(urls[0]); ResponseHandler<String> responseHandler = new BasicResponseHandler(); content = client.execute(httpget, responseHandler); } catch (ClientProtocolException e) { error = true; cancel(true); } catch (IOException e) { error = true; cancel(true); } return content; } protected void onPostExecute(String content) { dialog.dismiss(); if (error) { Toast toast = Toast.makeText(activity.this, getString(R.string.offline), Toast.LENGTH_LONG); toast.setGravity(Gravity.TOP, 0, 75); toast.show(); } else { activity.this.setResponseBody(content); } } } public void search() { String query = fieldSearch.getText().toString(); String url = "http://example.com/example.php?query=" + query; //this is just an example url, I have a "real" url in my application but for privacy reasons I've replaced it grabURL(url); // the method that will start the asynctask processData(responseBody); // process the responseBody and display stuff on the ui-thread with the data that I would like to get from the asyntask but doesn't obviously }

  • Android AlertDialog wait for result in calling activity

    - by insanesam
    I am trying to use an AlertDialog in my app to select the quantity of an item. The problem is that the activity that calls the AlertDialog doesn't wait for it to update the item before it adds it to the SQLite Database and change intents. At the moment, the QuantitySelector (AlertDialog) appears, then disappears straight away and changes the MealActivity class (which is just a ListView that reads from the database) through the intent change with an update to the database with quantity 0. I need the Activity to wait for the AlertDialog to close before it updates the database. What would be the correct way of implementing this? Here is some code for you: QuantitySelector (which runs the alertdialog): public class QuantitySelector{ protected static final int RESULT_OK = 0; private Context _context; private DatabaseHandler db; private HashMap<String, Double> measures; private Item item; private View v; private EditText quan; private NumberPicker pick; private int value; private Quantity quantity; /** * Function calls the quantity selector AlertDialog * @param _c: The application context * @param item: The item to be added to consumption * @return The quantity that is consumed */ public void select(Context _c, Item item, Quantity quantity){ this._context = _c; this.item = item; this.quantity = quantity; db = new DatabaseHandler(_context); //Get the measures to display createData(); //Set up the custom view LayoutInflater inflater = LayoutInflater.from(_context); v = inflater.inflate(R.layout.quantity_selector, null); //Set up the input fields quan = (EditText) v.findViewById(R.id.quantityNumber); pick = (NumberPicker) v.findViewById(R.id.numberPicker1); //Set up the custom measures into pick pick.setMaxValue(measures.size()-1); pick.setDisplayedValues(measures.keySet().toArray(new String[0])); //Start the alert dialog runDialog(); } public void createData(){ measures = new HashMap<String, Double>(); //Get the measurements from the database if(item!=null){ measures.putAll(db.getMeasures(item)); } //Add grams as the default measurement if(!measures.keySet().contains("grams")){ //Add grams as a standard measure measures.put("grams", 1.0); } } public void runDialog(){ AlertDialog dialog = new AlertDialog.Builder(_context).setTitle("Select Quantity") .setView(v) .setPositiveButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { //Change the consumption to the new quantity if(!quan.getText().toString().matches("")){ value = Integer.parseInt(quan.getText().toString()); //Check if conversion from other units is needed String s[] = pick.getDisplayedValues(); String a = s[pick.getValue()]; //Convert the chosen measure back to grams if(!a.equals("grams")){ for(String m : measures.keySet()){ if(m==a){ value = (int) (value * measures.get(m)); } } } } quantity.setQuantity(value); dialog.dismiss(); } }) .setNegativeButton("Cancel", null).create(); dialog.show(); } } The method from favouritesAdapter (which calls the alertdialog): add.setOnClickListener(new OnClickListener(){ public void onClick(View arg0) { QuantitySelector q = new QuantitySelector(); Quantity quan = new Quantity(); q.select(_context, db.getItem(p.getID()), quan); db.addConsumption(p.getID(), p.getFavouriteShortName(), quan.getQuantity(), "FAVOURITE"); Intent intent = new Intent(_context,MealActivity.class); _context.startActivity(intent); } }); All help is appreciated :)

  • NullPointerException using EndlessAdapter with SimpleAdapter

    - by android_dev
    Hello, I am using EndlessAdapter from commonsguy with a SimpleAdapter. I can load data when I make a scroll down without problems, but I have a NullPointerException when I make a scroll up. The problem is in the method @Override public View getView(int position, View convertView,ViewGroup parent) { return wrapped.getView(position, convertView, parent); } from the class AdapterWrapper. The call to wrapped.getView(position, convertView,parent) raises the exception and I don´t know why. This is my implementation of EndlessAdapter: //Inner class in SearchTextActivity class DemoAdapter extends EndlessAdapter { private RotateAnimation rotate = null; DemoAdapter(ArrayList<HashMap<String, String>> result) { super(new SimpleAdapter(SearchTracksActivity.this, result, R.layout.textlist_item, PROJECTION_COLUMNS, VIEW_MAPPINGS)); rotate = new RotateAnimation( 0f, 360f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); rotate.setDuration(600); rotate.setRepeatMode(Animation.RESTART); rotate.setRepeatCount(Animation.INFINITE); } @Override protected View getPendingView(ViewGroup parent) { View row=getLayoutInflater().inflate(R.layout.textlist_item, null); View child=row.findViewById(R.id.title); child.setVisibility(View.GONE); child=row.findViewById(R.id.username); child.setVisibility(View.GONE); child=row.findViewById(R.id.throbber); child.setVisibility(View.VISIBLE); child.startAnimation(rotate); return row; } @Override @SuppressWarnings("unchecked") protected void rebindPendingView(int position, View row) { HashMap<String, String> res = (HashMap<String, String>)getWrappedAdapter().getItem(position); View child=row.findViewById(R.id.title); ((TextView)child).setText(res.get("title")); child.setVisibility(View.VISIBLE); child=row.findViewById(R.id.username); ((TextView)child).setText(res.get("username")); child.setVisibility(View.VISIBLE); ImageView throbber=(ImageView)row.findViewById(R.id.throbber); throbber.setVisibility(View.GONE); throbber.clearAnimation(); } boolean mFinal = true; @Override protected boolean cacheInBackground() { EditText searchText = (EditText)findViewById(R.id.searchText); String textToSearch = searchText.getText().toString(); Util.getSc().searchText(textToSearch , offset, limit, new ResultListener<ArrayList<Text>>() { @Override public void onError(Exception e) { e.toString(); mFinal = false; } @Override public void onSuccess(ArrayList<Text> result) { if(result.size() == 0){ mFinal = false; }else{ texts.addAll(result); offset++; } } }); return mFinal; } @Override protected void appendCachedData() { for(Text text : texts){ result.add(text.getMapValues()); } texts.clear(); } } And I use it this way: public class SearchTextActivity extends AbstractListActivity { private static final String[] PROJECTION_COLUMNS = new String[] { TextStore.Text.TITLE, TextStore.Text.USER_NAME}; private static final int[] VIEW_MAPPINGS = new int[] { R.id.Text_title, R.id.Text_username}; ArrayList<HashMap<String, String>> result; static ArrayList<Text> texts; static int offset = 0; static int limit = 1; @Override void onAbstractCreate(Bundle savedInstance) { setContentView(R.layout.search_tracks); setupViews(); } private void setupViews() { ImageButton searchButton = (ImageButton)findViewById(R.id.searchButton); updateView(); } SimpleAdapter adapter; void updateView(){ if(result == null) { result = new ArrayList<HashMap<String, String>>(); } if(tracks == null) { texts = new ArrayList<Text>(); } } public void sendQuery(View v){ offset = 0; texts.clear(); result.clear(); setListAdapter(new DemoAdapter(result)); } } Does anybody knows what could be the problem? Thank you in advance

  • Socket php server not showing messages sent from android client

    - by Mj1992
    Hi I am a newbie in these kind of stuff but here's what i want to do. I am trying to implement a chat application in which users will send their queries from the website and as soon as the messages are sent by the website users.It will appear in the android mobile application of the site owner who will answer their queries .In short I wanna implement a live chat. Now right now I am just simply trying to send messages from android app to php server. But when I run my php script from dreamweaver in chrome the browser keeps on loading and doesn't shows any output when I send message from the client. Sometimes it happened that the php script showed some outputs which I have sent from the android(client).But i don't know when it works and when it does not. So I want to show those messages in the php script as soon as I send those messages from client and vice versa(did not implemented the vice versa for client but help will be appreciated). Here's what I've done till now. php script: <?php set_time_limit (0); $address = '127.0.0.1'; $port = 1234; $sock = socket_create(AF_INET, SOCK_STREAM, 0); socket_bind($sock, $address, $port) or die('Could not bind to address'); socket_listen($sock); $client = socket_accept($sock); $welcome = "Roll up, roll up, to the greatest show on earth!\n? "; socket_write($client, $welcome,strlen($welcome)) or die("Could not send connect string\n"); do{ $input=socket_read($client,1024,1) or die("Could not read input\n"); echo "User Says: \n\t\t\t".$input; if (trim($input) != "") { echo "Received input: $input\n"; if(trim($input)=="END") { socket_close($spawn); break; } } else{ $output = strrev($input) . "\n"; socket_write($spawn, $output . "? ", strlen (($output)+2)) or die("Could not write output\n"); echo "Sent output: " . trim($output) . "\n"; } } while(true); socket_close($sock); echo "Socket Terminated"; ?> Android Code: public class ServerClientActivity extends Activity { private Button bt; private TextView tv; private Socket socket; private String serverIpAddress = "127.0.0.1"; private static final int REDIRECTED_SERVERPORT = 1234; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); bt = (Button) findViewById(R.id.myButton); tv = (TextView) findViewById(R.id.myTextView); try { InetAddress serverAddr = InetAddress.getByName(serverIpAddress); socket = new Socket(serverAddr, REDIRECTED_SERVERPORT); } catch (UnknownHostException e1) { e1.printStackTrace(); } catch (IOException e1) { e1.printStackTrace(); } bt.setOnClickListener(new OnClickListener() { public void onClick(View v) { try { EditText et = (EditText) findViewById(R.id.EditText01); String str = et.getText().toString(); PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true); out.println(str); Log.d("Client", "Client sent message"); } catch (UnknownHostException e) { tv.setText(e.getMessage()); e.printStackTrace(); } catch (IOException e) { tv.setText(e.getMessage()); e.printStackTrace(); } catch (Exception e) { tv.setText(e.getMessage()); e.printStackTrace(); } } }); } } I've just pasted the onclick button event code for Android.Edit text is the textbox where I am going to enter my text. The ip address and port are same as in php script.
