I'm trying to crate a viewpager transition inside a fragment class which itself derived from another fragment class. Whenever I'm trying to create the viewpager its showing the following error.
02-09 11:28:34.321: E/AndroidRuntime(8520): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.gm.gakkmusic/com.gm.gakkmusic.MainActivity}: java.lang.IllegalStateException: Recursive entry to executePendingTransactions

After searching for a while in StackOverflow I found that I've to use getChildFragmentManager() while nesting a child fragment to its main fragment but I'm kinda confused about the whole process. It would be nice if anyone can figure this problem and give a quick solution.
Sources are given below,
This is where the Fragment1 is created from the MainActivity.class
@Override
public void onNavigationDrawerItemSelected(int position) {
FragmentManager fragmentManager = getSupportFragmentManager();
switch (position) {
case 0:
fragmentManager.beginTransaction()
.replace(R.id.container, new Fragment1())
.commit();
break;
}
}
Fragment1.class is the parent Fragment and inside it the child viewpager transition is created,
public class Fragment1 extends Fragment implements OnItemClickListener {
private Fragment contentFragment;
SliderFragment sliderFragment;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
if (savedInstanceState != null) {
if (fragmentManager.findFragmentByTag(SliderFragment.ARG_ITEM_ID) != null) {
sliderFragment = (SliderFragment) fragmentManager
.findFragmentByTag(SliderFragment.ARG_ITEM_ID);
contentFragment = sliderFragment;
}
} else {
sliderFragment = new SliderFragment();
switchContent(sliderFragment, SliderFragment.ARG_ITEM_ID);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View content = inflater.inflate(R.layout.fragment1_layout, container,
false);
return content;
}
@Override
public void onSaveInstanceState(Bundle outState) {
if (contentFragment instanceof SliderFragment) {
outState.putString("content", SliderFragment.ARG_ITEM_ID);
}
super.onSaveInstanceState(outState);
}
public void switchContent(Fragment fragment, String tag) {
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
while (fragmentManager.popBackStackImmediate())
;
if (fragment != null) {
FragmentTransaction transaction = fragmentManager
.beginTransaction();
transaction.replace(R.id.content_frame, fragment, tag);
if (!(fragment instanceof SliderFragment)) {
transaction.addToBackStack(tag);
}
transaction.commit();
contentFragment = fragment;
}
}
public void onBackPressed() {
FragmentManager fm = getActivity().getSupportFragmentManager();
if (fm.getBackStackEntryCount() > 0) {
super.getActivity().onBackPressed();
} else if (contentFragment instanceof SliderFragment
|| fm.getBackStackEntryCount() == 0) {
getActivity().finish();
}
}
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Log.i(LOG_TAG, "onItemClick: " + position);
Log.d(LOG_TAG, "checked items: " + listView.getCheckedItemCount());
Log.d(LOG_TAG,
"checked positions: " + listView.getCheckedItemPositions());
}
}
UPDATE: I've already solved the problem by replacing all getSupportFragmentManager() to getChildFragmentManager() but I'm still looking for an efficient way to solve this.
