i implemented a contextual action mode bar in a nested fragement. This fragment is part of a view pager and the view pager is also a fragment and part of a navigation drawer.
My Problem: I want to close the contextual action mode bar if the fragment is no more focused. So, if I swipe through the view pager the action mode bar should close. But if I use the onPause() method of the nested fragment, the method is not called directly. Often it waits until i swiped two or three times forward... Here are some pictures:
In the second picture you can see that the action mode bar is still there. So my question is:
In which method should I call my actionModeBar.finish() method, to close directly the action mode bar if i leave the fragment?
Maybe the code of the fragment helps you:
public class EditorFragment extends Fragment {
private static final String KEY_POSITION="position";
ListView listView;
private boolean isMultipleList = false;
private ActionMode acMode;
private int counterChecked = 0;
private ActionMode.Callback modeCallBack = new ActionMode.Callback() {
public boolean onPrepareActionMode(ActionMode mode, Menu menu){
return false;
}
public void onDestroyActionMode(ActionMode mode) {
listView.clearChoices();
for (int i = 0; i < listView.getChildCount(); i++)
listView.setItemChecked(i, false);
listView.post(new Runnable() {
@Override
public void run() {
listView.setChoiceMode(ListView.CHOICE_MODE_NONE);
}
});
isMultipleList = false;
counterChecked = 0;
mode = null;
}
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
mode.setTitle("1 Aufgabe");
mode.getMenuInflater().inflate(R.menu.actionmode, menu);
return true;
}
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.actionmode_delete:
int choiceCount = listView.getCount();
SparseBooleanArray spBoolArray = listView.getCheckedItemPositions();
DBAufgaben db = new DBAufgaben(MainActivity.getMContext());
db.open();
for (int i = 0; i < choiceCount; i++) {
if(spBoolArray.get(i)){
db.deletContact(listView.getItemIdAtPosition(i));
}
}
Cursor cursor = db.getAllRecords();
AdapterEingang adapterE = new AdapterEingang(MainActivity.getMContext(), cursor, 0);
listView.setAdapter(adapterE);
db.close();
mode.finish();
break;
case R.id.actionmode_cancel:
mode.finish();
break;
}
return false;
}
