  • Android: Speeding up display of (html-formatted) text

    - by prepbgg
    My app uses a StringBuilder to assemble paragraphs of text which are then displayed in a TextView within a ScrollView. The displaytext.xml layout file is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#FFFFFF" xmlns:android="http://schemas.android.com/apk/res/android"> <ScrollView android:id="@+id/ScrollView01" android:layout_width="fill_parent" android:layout_height="wrap_content" > <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/display_text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="#000000" > </TextView> </ScrollView> </LinearLayout> and the code that displays the StringBuilder object sbText is setContentView(R.layout.displaytext); TextView tv = (TextView)findViewById(R.id.display_text); tv.setText(Html.fromHtml(sbText.toString())); This works OK, except that it gets very slow as the amount of text grows. For example, to display 50 paragraphs totalling about 50KB of text takes over 5 seconds just to execute those three lines of code. Can anyone suggest how I can speed this up, please?

  • Images from url to listview

    - by Andres
    I have a listview which I show video results from YouTube. Everything works fine but one thing I noticed is that the way it works seems to be a bit slow and it might be due to my code. Are there any suggestions on how I can make this better? Maybe loading the images directly from the url instead of using a webclient? I am adding the listview items in a loop from video feeds returned from a query using the YouTube API. The piece of code which I think is slowing it down is this: Feed<Video> videoFeed = request.Get<Video>(query); int i = 0; foreach (Video entry in videoFeed.Entries) { string[] info = printVideoEntry(entry).Split(','); WebClient wc = new WebClient(); wc.DownloadFile(@"http://img.youtube.com/vi/" + info[0].ToString() + "/hqdefault.jpg", info[0].ToString() + ".jpg"); string[] row1 = { "", info[0].ToString(), info[1].ToString() }; ListViewItem item = new ListViewItem(row1, i); YoutubeList.Items.Add(item); imageListSmall.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); imageListLarge.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); } public static string printVideoEntry(Video video) { return video.VideoId + "," + video.Title; } As you can see I use a Webclient which downloads the images so then I can use them as image in my listview. It works but what I'm concerned about is speed..any suggestions? maybe a different control all together?

  • Adding a row to a ListView that displays "Loading" while information is downloaded. Like in the Market.

    - by user577139
    I've tried, but have had no luck trying to find this answer elsewhere. I want to add a row to the bottom of my listview that displays "Loading..." and maybe a spinning progress indicator. My program already loads additional information into the listview once the user scrolls to the bottom. But I want the user to be able to see that the program is indeed loading something. Example: If you go to the android marketplace and scroll to the bottom of one of the lists, the last row will say "Loading...". Then once the data is loaded, that bar is replaced with the first item of the new data. Sorry, it's a little hard to describe. I am NOT trying to add a footer to the bottom of the list view. I want it to be an actual item in the listview.

  • After downloading an application with two Launcher components from the Marketplace, clicking "Open"

    - by user267728
    Create a sample application with two launcher icons. For example, two components such as: <application ...> <activity ... android:name="TestActivity01"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity ... android:name="TestActivity02"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> Either install the application via downloading from the Marketplace, or via AppInstaller. When the message box asks you if you would like to run the application, an exception is thrown: 02-03 16:42:44.270: ERROR/AndroidRuntime(395): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.xxx.xxx/com.android.internal.app.ResolverActivity}; have you declared this activity in your AndroidManifest.xml? 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1 480) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.app.Instrumentation.execStartActivity(Instrumentation.java:1454) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.app.Activity.startActivityForResult(Activity.java:2660) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.app.Activity.startActivity(Activity.java:2704) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at com.android.packageinstaller.InstallAppDone.onClick(InstallAppDone.java:105 ) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.view.View.performClick(View.java:2344) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.view.View.onTouchEvent(View.java:4133) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.widget.TextView.onTouchEvent(TextView.java:6504) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.view.View.dispatchTouchEvent(View.java:3672) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:882) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:882) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:882) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:882) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at com.android.internal.policy.impl.PhoneWindow$DecorView.superDispatchTouchEv ent(PhoneWindow.java:1712) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at com.android.internal.policy.impl.PhoneWindow.superDispatchTouchEvent(PhoneW indow.java:1202) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.app.Activity.dispatchTouchEvent(Activity.java:1987) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at com.android.internal.policy.impl.PhoneWindow$DecorView.dispatchTouchEvent(P honeWindow.java:1696) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.view.ViewRoot.handleMessage(ViewRoot.java:1658) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.os.Handler.dispatchMessage(Handler.java:99) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.os.Looper.loop(Looper.java:123) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at android.app.ActivityThread.main(ActivityThread.java:4203) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at java.lang.reflect.Method.invokeNative(Native Method) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at java.lang.reflect.Method.invoke(Method.java:521) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java: 791) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) 02-03 16:42:44.270: ERROR/AndroidRuntime(395): at dalvik.system.NativeStart.main(Native Method) The crash happens because com.android.internal.app.ResolverActivity is trying to find a (single) component which resolves the following intent: <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> Please note that this has been tested BOTH with the AppInstaller, and the actual Marketplace on a real device.

  • Android mapView ItemizedOverlay setFocus does not work properly

    - by Gaks
    Calling setFocus(null) on the ItemizedOverlay does not 'unfocus' current marker. According to the documentation: ... If the Item is not found, this is a no-op. You can also pass null to remove focus. Here's my code: MapItemizedOverlay public class MapItemizedOverlay extends ItemizedOverlay<OverlayItem> { private ArrayList<OverlayItem> items = new ArrayList<OverlayItem>(); public MapItemizedOverlay(Drawable defaultMarker) { super(defaultMarker); } public void addOverlay(OverlayItem overlay) { items.add(overlay); populate(); } @Override protected OverlayItem createItem(int i) { return items.get(i); } @Override public int size() { return items.size(); } } Creating map overlay and one marker: StateListDrawable youIcon = (StateListDrawable)getResources().getDrawable(R.drawable.marker_icon); int width = youIcon.getIntrinsicWidth(); int height = youIcon.getIntrinsicHeight(); youIcon.setBounds(-13, 0-height, -13+width, 0); GeoPoint location = new GeoPoint(40800816,-74122009); MapItemizedOverlay overlay = new MapItemizedOverlay(youIcon); OverlayItem item = new OverlayItem(location, "title", "snippet"); overlay.addOverlay(item); mapView.getOverlays().add(overlay); The R.drawable.marker_icon is defined as follows: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="true" android:drawable="@drawable/marker_selected" /> <item android:state_selected="true" android:drawable="@drawable/marker_selected" /> <item android:drawable="@drawable/marker_normal" /> </selector> Now, to test the setFocus() behavior I put the button on the activity window, with the following onClick listener: Button focusBtn = (Button)findViewById(R.id.focusbtn); focusBtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { for(Overlay ov : mapView.getOverlays()) { if(ov.getClass().getSimpleName().equals("MapItemizedOverlay") == true) { MapItemizedOverlay miv = (MapItemizedOverlay)ov; if(miv.getFocus() == null) miv.setFocus(miv.getItem(0)); else miv.setFocus(null); break; } } mapView.invalidate(); } }); The expected behavior is: clicking on the button toggles marker selection. It works only once - clicking it for the first time selects the marker, clicking it again does not de-select the marker. The most weird thing about it is that after calling setFocus(null), getFocus() also returns null - like the overlay has no focused item (I debugged it). But even after calling mapView.invalidate() the marker is still drawn in 'selected'(focused) state.

  • Android Drawable question.

    - by Tarmon
    Hey Everyone, I am trying to create a drawable in code and change the color based on some criteria. I can get it to work but it doesn't want to let me set the padding on the view. Any help would be appreciated. <?xml version="1.0" encoding="utf-8"?> <ImageView android:id="@+id/icon" android:layout_width="50px" android:layout_height="fill_parent" /> <TextView android:id="@+id/label" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingLeft="17px" android:textSize="28sp" /> ImageView icon = (ImageView) row.findViewById(R.id.icon); ShapeDrawable mDrawable; int x = 0; int y = 0; int width = 50; int height = 50; float[] outerR = new float[] { 12, 12, 12, 12, 12, 12, 12, 12 }; mDrawable = new ShapeDrawable(new RoundRectShape(outerR, null, null)); mDrawable.setBounds(x, y+height, x + width, y); switch(position){ case 0: mDrawable.getPaint().setColor(0xffff0000); //Red break; case 1: mDrawable.getPaint().setColor(0xffff0000); //Red break; case 2: mDrawable.getPaint().setColor(0xff00c000); //Green break; case 3: mDrawable.getPaint().setColor(0xff00c000); //Green break; case 4: mDrawable.getPaint().setColor(0xff0000ff); //Blue break; case 5: mDrawable.getPaint().setColor(0xff0000ff); //Blue break; case 6: mDrawable.getPaint().setColor(0xff696969); //Gray break; case 7: mDrawable.getPaint().setColor(0xff696969); //Gray break; case 8: mDrawable.getPaint().setColor(0xffffff00); //Yellow break; case 9: mDrawable.getPaint().setColor(0xff8b4513); //Brown break; case 10: mDrawable.getPaint().setColor(0xff8b4513); //Brown break; case 11: mDrawable.getPaint().setColor(0xff8b4513); //Brown break; case 12: mDrawable.getPaint().setColor(0xffa020f0); //Purple break; case 13: mDrawable.getPaint().setColor(0xffff0000); //Red break; case 14: mDrawable.getPaint().setColor(0xffffd700); //Gold break; case 15: mDrawable.getPaint().setColor(0xffff6600); //Orange break; } icon.setBackgroundDrawable(mDrawable); icon.setPadding(5, 5, 5, 5); If I set the padding in XML it just ignores it.

I don't have access to the handset and cannot find anyone with one where I live.
