MapView in a Fragment (Honeycomb)

February 5, 2023 by Tarik

I’ve managed to resolve this by using TabHost in fragment. Here is the idea (briefly): MainFragmentActivity extends FragmentActivity (from support library) and has MapFragment. MyMapActivity extends MapActivity and contain MapView. LocalActivityManagerFragment hosts LocalActivityManager MapFragment extends LocalActivityManagerFragment. And LocalActivityManager contains MyMapActivity activity in it. Example implementation: https://github.com/inazaruk/map-fragment.

Fragments onResume from back stack

January 3, 2023 by Tarik

For a lack of a better solution, I got this working for me: Assume I have 1 activity (MyActivity) and few fragments that replaces each other (only one is visible at a time). In MyActivity, add this listener: getSupportFragmentManager().addOnBackStackChangedListener(getListener()); (As you can see I’m using the compatibility package). getListener implementation: private OnBackStackChangedListener getListener() { OnBackStackChangedListener … Read more

Unable to resolve host “” No address associated with hostname

My bet is that you forgot to give your app the permission to use the internet. Try adding this to your android manifest: <uses-permission android:name=”android.permission.INTERNET” /> <uses-permission android:name=”android.permission.ACCESS_NETWORK_STATE” />

Is there a method that works like start fragment for result?

January 1, 2023 by Tarik

All of the Fragments live inside Activities. Starting a Fragment for a result doesn’t make much sense, because the Activity that houses it always has access to it, and vice versa. If the Fragment needs to pass on a result, it can access its Activity and set its result and finish it. In the case … Read more

SearchView’s OnCloseListener doesn’t work

December 30, 2022 by Tarik

I also meet this problem, and I have no choice but give up “oncloselistener”. Instead, you can get your menuItem, then setOnActionExpandListener. Then override unimplents methods. @Override public boolean onMenuItemActionExpand(MenuItem item) { // TODO Auto-generated method stub Log.d(“*******”,”onMenuItemActionExpand”); return true; } @Override public boolean onMenuItemActionCollapse(MenuItem item) { //do what you want to when close the … Read more

Android: How to change the ActionBar “Home” Icon to be something other than the app icon?

December 25, 2022 by Tarik

The ActionBar will use the android:logo attribute of your manifest, if one is provided. That lets you use separate drawable resources for the icon (Launcher) and the logo (ActionBar, among other things).

How to implement the Android ActionBar back button?

November 21, 2022 by Tarik

Selvin already posted the right answer. Here, the solution in pretty code: public class ServicesViewActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // etc… getActionBar().setDisplayHomeAsUpEnabled(true); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: NavUtils.navigateUpFromSameTask(this); return true; default: return super.onOptionsItemSelected(item); } } } The function NavUtils.navigateUpFromSameTask(this) requires you to … Read more

How to set a Fragment tag by code?

November 20, 2022 by Tarik

Yes. So the only way is at transaction time, e.g. using add, replace, or as part of the layout. I determined this through an examination of the compatibility sources as I briefly looked for similar at some point in the past.
