As a mobile developer, I was sad to find nothing native that supports auto resizing. My searches did not turn up anything that worked for me and in the end, I spent the better half of my weekend and created my own auto resize text view. I will post the code here and hopefully it … Read more
The hosting activity overrides onActivityResult(), but it did not make a call to super.onActivityResult() for unhandled result codes. Apparently, even though the fragment is the one making the startActivityForResult() call, the activity gets the first shot at handling the result. This makes sense when you consider the modularity of fragments. Once I implemented super.onActivityResult() for … Read more
Add the following style in your res/values/styles.xml file (if you don’t have one, create it.) Here’s a complete file: <?xml version=”1.0″ encoding=”utf-8″?> <resources> <style name=”Theme.Transparent” parent=”android:Theme”> <item name=”android:windowIsTranslucent”>true</item> <item name=”android:windowBackground”>@android:color/transparent</item> <item name=”android:windowContentOverlay”>@null</item> <item name=”android:windowNoTitle”>true</item> <item name=”android:windowIsFloating”>true</item> <item name=”android:backgroundDimEnabled”>false</item> </style> </resources> (The value @color/transparent is the color value #00000000 which I put in the res/values/color.xml file. … Read more
There are two options for creating and updating databases. One is to create a database externally, then place it in the assets folder of the project and then copy the entire database from there. This is much quicker if the database has a lot of tables and other components. Upgrades are triggered by changing the … Read more

Yes, it’s possible. Just implement getItemViewType(), and take care of the viewType parameter in onCreateViewHolder(). So you do something like: public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> { class ViewHolder0 extends RecyclerView.ViewHolder { … public ViewHolder0(View itemView){ … } } class ViewHolder2 extends RecyclerView.ViewHolder { … public ViewHolder2(View itemView){ … } @Override public int getItemViewType(int position) { … Read more
Try this: UPDATE: Kotlin: editText.setSelection(editText.length())//placing cursor at the end of the text Java: editText.setSelection(editText.getText().length());
Your version of Eclipse is 64-bit, based on the paths and filenames. However, the version of Java that it’s picking up is 32-bit, as indicated by where it is coming from, on this line: -vm C:\Program Files (x86)\Java\jre7\bin\javaw.exe Program Files (x86) is the folder where 64-bit Windows places 32-bit programs. Program Files is the folder … Read more
Add android:screenOrientation=”portrait” to the activity in the AndroidManifest.xml. For example: <activity android:name=”.SomeActivity” android:label=”@string/app_name” android:screenOrientation=”portrait” /> Since this has become a super-popular answer, I feel very guilty as forcing portrait is rarely the right solution to the problems it’s frequently applied to. The major caveats with forced portrait: This does not absolve you of having to … Read more
I use the following from inside an activity: private boolean isMyServiceRunning(Class<?> serviceClass) { ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE); for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) { if (serviceClass.getName().equals(service.service.getClassName())) { return true; } } return false; } And I call it using: isMyServiceRunning(MyService.class) This works reliably, because it is based on the information about running services provided by … Read more
