Android FragmentTransaction commit already called
You are beginning the FragmentTransaction outside of the OnItemClickListener
. Thus you are attempting to commit()
a single FragmentTransaction every time the user clicks an item in your ListView.
You need to begin a new FragmentTransaction every time you intend to perform any number of Fragment operations.
A simple fix would look like this:
f1_fragment = new F1_Fragments();
f2_fragment = new F2_Fragments();
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
FragmentTransaction fragmentTransaction =getFragmentManager().beginTransaction();
parent.getItemAtPosition(position);
if(position==0){
fragmentTransaction.replace(android.R.id.content, f1_fragment);
}else{
fragmentTransaction.replace(android.R.id.content, f2_fragment);
}
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
you can use this method for replace fragment with each other just call this
do those are global
YourFragment1 frg1 = new YourFragment1 ();
YourFragment2 frg1 = new YourFragment2 ();
And then call it by
openFragment(frg1);
or
openFragment(frg2);
OpenFragment:
private void openFragment(final Fragment fragment) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.container, fragment);
transaction.addToBackStack(null);
transaction.commit();
}
