  • Rotating images makes ui slow

    - by 5w4rley
    i'm trying to implement kind of speedometer. i'm getting informations about rounds per minute, boost and load of an engine over bluetooth and i try to display them on the screen witch 3 arrows witch should point in the right direktion. i tried to use a rotate animation evry time i get data(10-100ms) to setup the arrows. but that makes my ui extremly slow. 500ms to react on a buttonclick. Doese someone know how to make it work better? source code: public void setTacho() { //rotate Tachonadel Rpmcurrentdegree=Rpmcurrentdegree+Rpmdegree; Rpmdegree=((rpms-lastrpm)*RPMtoDegree); RpmAnim=new RotateAnimation((float)Rpmcurrentdegree, (float)Rpmdegree, ivNadel.getWidth()/2, ivNadel.getHeight()/2); RpmAnim.setFillEnabled(true); RpmAnim.setFillAfter(true); ivNadel.setAnimation(RpmAnim); RpmAnim.start(); //rotate Boostbalken currentBoostDegree=currentBoostDegree+BoostDegree; BoostDegree=(boost-lastBoost)*BOOSTtoDegree; //rotate Loadbalken currentLoadDegree=currentLoadDegree+LoadDegree; LoadDegree=(load-lastLoad)*LOADtoDegree; BoostAnim=new RotateAnimation((float)-currentBoostDegree, (float)-BoostDegree, ivBoost.getWidth()/2, ivBoost.getHeight()/2); BoostAnim.setFillEnabled(true); BoostAnim.setFillAfter(true); ivBoost.setAnimation(BoostAnim); BoostAnim.start(); LoadAnim=new RotateAnimation((float)currentLoadDegree, (float)LoadDegree, ivLoad.getWidth()/2, ivLoad.getHeight()/2); LoadAnim.setFillEnabled(true); LoadAnim.setFillAfter(true); ivLoad.setAnimation(LoadAnim); LoadAnim.start(); } when i try to make the rotation only if the values have changed then it works only while they are changing but if they aren't the arrows jump back to the zero position. isnt setfillafter to tell the image that it should hold the new position? code: public void setTacho() { //rotate Tachonadel Rpmcurrentdegree=Rpmcurrentdegree+Rpmdegree; Rpmdegree=((rpms-lastrpm)*RPMtoDegree); if(Rpmdegree!=0) { RpmAnim=new RotateAnimation((float)Rpmcurrentdegree, (float)Rpmdegree, ivNadel.getWidth()/2, ivNadel.getHeight()/2); RpmAnim.setFillEnabled(true); RpmAnim.setFillAfter(true); ivNadel.setAnimation(RpmAnim); RpmAnim.start(); } //rotate Boostbalken currentBoostDegree=currentBoostDegree+BoostDegree; BoostDegree=(boost-lastBoost)*BOOSTtoDegree; //rotate Loadbalken currentLoadDegree=currentLoadDegree+LoadDegree; LoadDegree=(load-lastLoad)*LOADtoDegree; if(BoostDegree!=0) { BoostAnim=new RotateAnimation((float)-currentBoostDegree, (float)-BoostDegree, ivBoost.getWidth()/2, ivBoost.getHeight()/2); BoostAnim.setFillEnabled(true); BoostAnim.setFillAfter(true); ivBoost.setAnimation(BoostAnim); BoostAnim.start(); } if(LoadDegree!=0) { LoadAnim=new RotateAnimation((float)currentLoadDegree, (float)LoadDegree, ivLoad.getWidth()/2, ivLoad.getHeight()/2); LoadAnim.setFillEnabled(true); LoadAnim.setFillAfter(true); ivLoad.setAnimation(LoadAnim); LoadAnim.start(); } } i don't get it =( thx 4 help EDIT: part of the bluetooth Thread that calls the callback while (run) { try { bytes = mmInStream.read(buffer); if (connection.btCallback != null) { connection.btCallback.getData(buffer,bytes); } } catch (IOException e) { break; } the callback methode of the bluetooth thread: public void getData(byte[] bytes, int len) { setTacho(); }

  • How do I make java wait for boolean to run funciton

    - by TWeeKeD
    I'm sure this is pretty simple but I can't figure out and it sucks I'm up on suck on (what should be) an easy step. ok. I have a method that runs one function that give a response. this method actually handles the uploading of the file so o it takes a second to give a response. I need this response in the following method. sendPicMsg needs to complete and then forward it's response to sendMessage. Please help. b1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if(!uploadMsgPic.equalsIgnoreCase("")){ Log.v("response","Pic in storage"); sendPicMsg(); sendMessage(); }else{ sendMessage(); } 1st Method public void sendPicMsg(){ Log.v("response", "sendPicMsg Loaded"); if(!uploadMsgPic.equalsIgnoreCase("")){ final SharedPreferences preferences = this.getActivity().getSharedPreferences("MyPreferences", getActivity().MODE_PRIVATE); AsyncHttpClient client3 = new AsyncHttpClient(); RequestParams params3 = new RequestParams(); File file = new File(uploadMsgPic); try { File f = new File(uploadMsgPic.replace(".", "1.")); f.createNewFile(); //Convert bitmap to byte array Bitmap bitmap = decodeFile(file,400); ByteArrayOutputStream bos = new ByteArrayOutputStream(); bitmap.compress(CompressFormat.PNG, 0 /*ignored for PNG*/, bos); byte[] bitmapdata = bos.toByteArray(); //write the bytes in file FileOutputStream fos = new FileOutputStream(f); fos.write(bitmapdata); params3.put("file", f); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } params3.put("email", preferences.getString("loggedin_user", "")); params3.put("webversion", "1"); client3.post("http://peekatu.com/apiweb/msgPic_upload.php",params3, new AsyncHttpResponseHandler() { @Override public void onSuccess(String response) { Log.v("response", "Upload Complete"); refreshChat(); //responseString = response; Log.v("response","msgPic has been uploaded"+response); //parseChatMessages(response); response=picurl; uploadMsgPic = ""; if(picurl!=null){ Log.v("response","picurl is set"); } if(picurl==null){ Log.v("response", "picurl no ready"); }; } }); sendMessage(); } } 2nd Method public void sendMessage(){ final SharedPreferences preferences = this.getActivity().getSharedPreferences("MyPreferences", getActivity().MODE_PRIVATE); if(preferences.getString("Username", "").length()<=0){ editText1.setText(""); Toast.makeText(this.getActivity(), "Please Login to send messages.", 2); return; } AsyncHttpClient client = new AsyncHttpClient(); RequestParams params = new RequestParams(); if(type.equalsIgnoreCase("3")){ params.put("toid",user); params.put("action", "sendprivate"); }else{ params.put("room", preferences.getString("selected_room", "Adult Lobby")); params.put("action", "insert"); } Log.v("response", "Sending message "+editText1.getText().toString()); params.put("message",editText1.getText().toString() ); params.put("media", picurl); params.put("email", preferences.getString("loggedin_user", "")); params.put("webversion", "1"); client.post("http://peekatu.com/apiweb/messagetest.php",params, new AsyncHttpResponseHandler() { @Override public void onSuccess(String response) { refreshChat(); //responseString = response; Log.v("response", response); //parseChatMessages(response); if(picurl!=null) Log.v("response", picurl); } }); editText1.setText(""); lv.setSelection(adapter.getCount() - 1); }

    - by klaus-vlad
    Hi, I have a curiosity about application updates . What happens after such a process with the resources supposing that the update needs different resources than the ones the old version used ?

  • Can't get Dialog hosting a WebView to layout properly

    - by user246114
    Hi, I'm trying to host a webview on a dialog, without a titlebar, but I'm getting odd layout results. Example test: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); WindowManager wm = (WindowManager)getContext().getSystemService(Context.WINDOW_SERVICE); Display display = wm.getDefaultDisplay(); LinearLayout ll = new LinearLayout(getContext()); ll.setOrientation(LinearLayout.VERTICAL); ll.setLayoutParams(new LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); ll.setMinimumWidth(display.getWidth() - 10); ll.setMinimumHeight(display.getHeight() - 10); WebView wv = new WebView(getContext()); wv.setLayoutParams(new LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); wv.getSettings().setJavaScriptEnabled(true); ll.addView(mWebView); setContentView(ll, new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT)); } the dialog is inflated at startup, but the webview is not visible. If I rotate the device, it becomes visible, and fills the whole parent layout as requested. What is the right way to do this? I simply want a dialog which occupies most of the device screen, and has a WebView on it which fills the entire space. Thanks

  • What is the optimal way to animate a drawable within a view using the animator classes?

    - by littleFluffyKitty
    I have read about Property Animation and Hardware Acceleration but I am still uncertain what is the most efficient way to use the animator classes. (For the sake of this question I don't need to support devices before Honeycomb. So I want to use the animator classes.) For example, say I have a View. In this view I have a BitmapDrawable that I want to fade in. There are also many other elements within the view that won't change. What property or object would be best to use with the animator? The drawable? A paint that I am drawing the bitmap with in onDraw? Something else? How can this be done to be most efficient with hardware acceleration? Will this require calling invalidate for each step of the animation or is there a way to animate just the drawable and not cause the rest of the view to be redrawn completely for each step of the animation? I guess I imagine an optimal case would be the rest of the view not having to be completely redrawn in software, but rather hardware acceleration efficiently fading the drawable. Any suggestions or pointers to recommended approaches? Thanks!

  • Passing GPS speed via the Eclipse Emulator Control

    - by Nick
    Hi, my app queries the GPS-speed using .getSpeed() on a LocationListener. Is there a way to set this speed using the Eclipse Emulator Control or the command line? I tried to feed multiple sets of coordinates to the emulator via the manual GPS-control, but it didn't pick up a speed from that. Also, using a pre-defined GPX-file and playing it doesn't work for me. I would like to test my app without having to take it on a test-drive in my car every time ;)! Thanks!

  • How to prevent application thievery?

    - by Berdon Magnus
    Hey, I was wondering what the most effective way of preventing people from stealing my application (downloading a copy of the .apk online rather than buying it). I've spent a lot of time on one in particular (Droidbox) and won't be releasing Sync until I can guarantee that the people who are providing illegal copies of the pro version aren't able to. Anyone implemented this? I've tried checking my package signature verses an the signature of an unsigned copy but it appears to be the same - perhaps I'm doing something incorrectly here. I'm unsure whether people actually distribute the signed .apk in which case I don't think signature validation would work to begin with...

  • What happens to thread as onDestroy is called when device is rotated

    - by Lakshmie
    I would like to know as to what will happen to the thread which has been created by an activity and the device is rotated. I have observed that the onDestroy method is called when this happens. Will the thread be killed too? If the thread is not killed, how can I reassociate the thread with the activity as a new instance of the activity is created on rotation. Thanks, Lakshmie

  • Animation not start immediately when the target view is out of window

    - by funnything
    Hi. When I apply some animation to the view, which is out of window, the animation not start immediately. And then, I scroll the screen to show the animation target view, the animation will start. I hope to the animation will start immediately when it apply. Any ideas? Bellow is sample code. Thank you. public class AnimationValidationActivity extends Activity { private ViewSwitcher _viewSwitcher; private Button _button; /** * utility method for animation */ private Animation buildTranslateAnimation( float fromXDelta , float toXDelta , float fromYDelta , float toYDelta ) { Animation ret = new TranslateAnimation( fromXDelta , toXDelta , fromYDelta , toYDelta ); ret.setDuration( 1000 ); return ret; } /** * build view in place of layout.xml */ private View buildView() { ScrollView ret = new ScrollView( this ); ret.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , LinearLayout.LayoutParams.WRAP_CONTENT ) ); LinearLayout parent = new LinearLayout( this ); parent.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , LinearLayout.LayoutParams.WRAP_CONTENT ) ); parent.setOrientation( LinearLayout.VERTICAL ); ret.addView( parent ); _viewSwitcher = new ViewSwitcher( this ); _viewSwitcher.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , 100 ) ); parent.addView( _viewSwitcher ); View spacer = new View( this ); spacer.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , getWindow() .getWindowManager().getDefaultDisplay().getHeight() ) ); parent.addView( spacer ); _button = new Button( this ); _button.setText( "button" ); parent.addView( _button ); return ret; } @Override public void onCreate( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( buildView() ); _viewSwitcher.setFactory( new ViewSwitcher.ViewFactory() { @Override public View makeView() { TextView view = new TextView( AnimationValidationActivity.this ); view.setLayoutParams( new ViewSwitcher.LayoutParams( ViewSwitcher.LayoutParams.FILL_PARENT , ViewSwitcher.LayoutParams.FILL_PARENT ) ); view.setBackgroundColor( 0xffffffff ); view.setText( "foobar" ); return view; } } ); _button.setOnClickListener( new View.OnClickListener() { @Override public void onClick( View v ) { _viewSwitcher.setInAnimation( buildTranslateAnimation( _viewSwitcher.getWidth() , 0 , 0 , 0 ) ); _viewSwitcher.setOutAnimation( buildTranslateAnimation( 0 , - _viewSwitcher.getWidth() , 0 , 0 ) ); int color = new Random().nextInt(); _viewSwitcher.getNextView().setBackgroundColor( 0xff000000 | color & 0xffffff ); _viewSwitcher.showNext(); } } ); } }

  • How to set a custom font for a spinner?

    - by AndrewC
    Is there anyway to set a custom font or color for the selected item in a Spinner? For example, I open the spinner and click a priority of "High". I'm my layout containing the spinner, I would like to see the word "High" in red or a custom font. I can't seem to obtain the textview to make the necessary change. I always obtain a NullPointerException if I typecast the spinner.getSelectedView() to textview and attempt to set the color. any ideas? thanks in advance!

  • AdMob won't load programmatically

    - by scottbot95
    I'm need to include ads into my app and I have a settings option to disable ads. so I need to load the ad in code. I copied the code from google to handle that and when I set ads:loadAdOnCreate to true, it works just fine. But if I set it to false and add the two lines AdView adView = (AdView)this.findViewById(R.id.ad); adView.loadAd(new AdRequest()); The ads stop displaying. If I look at log cat, it shows that it is receiving an ad and trying to display it. However it won't actually display on screen. Help?

  • ImageView Force closes my application

    - by BlueFireLady
    Hi there I am really a beginner, and I have been fighting with this problem for 3 days. :( I am able to get an image to show using a grid view and an adapter as in the grid view tutorial, but I wanted to be able to just use ImageView in the xml. public class HelloImage extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView gridview = (ImageView) findViewById(R.id.gridview); gridview.setLayoutParams(new GridView.LayoutParams(85, 85)); gridview.setScaleType(ImageView.ScaleType.CENTER_CROP); gridview.setPadding(8, 8, 8, 8); gridview.setImageResource(R.drawable.hand_tool); } } When I run this it causes the app to force close when loading.

  • Is it possible to creating a Service without starting it?

    - by ThaMe90
    Hello all, I wonder, is it possible to create a Service, set some data, and then start it? I haven't come across a thread specific to this problem, so I would like to know if it is possible (if it is known of course). My problem is that I have a Service which listens to a DatagramSocket, but the socket in question needs to be set after creation, but before the start of the Service. The setting of the socket happens through the use of a Broadcast (I broadcast 2 Strings which hold the IP-Address & Port and the BroadcastReceiver then constructs a socket for me). When the Service is started, a Thread will start to run and listen to the supposedly created socket. This, sadly, doesn't happen. The socket will remain null and I can't set it when the Thread is running (This is another issue I hope to tackle in the future, if anybody got any ideas about this, please notify me). So, is what I want possible, or should I come up with another construct for achieving this goal?

  • Determining if an Activity exists on the current device?

    - by stormin986
    Is there a way to check and see if an Activity exists on your device? If I have a youtube video link I want to specify it open in the YouTube PlayerActivity. However, I don't want to crash if for some reason they don't have it. Is there a way to check and see if the activity exists? I don't think I can catch the runtime exception since startActivity() doesn't throw it.
