Error: searchItem.getActionView() returns null object
I'm reviving an old application I used to develop and I encouter a few problems.
The current one I'm facing is:
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.SearchView.setOnQueryTextFocusChangeListener(android.view.View$OnFocusChangeListener)' on a null object reference
Ofcourse, this happens because a previos call to getActionView() returns null.
I've tried to update the dependencies, but nothing worked.
This is the code I try to run:
@Override
public boolean onCreateOptionsMenu(Menu menu)
getMenuInflater().inflate(R.menu.main, menu);
final MenuItem searchItem = menu.findItem(R.id.search);
et = (SearchView) searchItem.getActionView();
et.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener()
@Override
public void onFocusChange(View v, boolean hasFocus)
// TODO Auto-generated method stub
if (hasFocus)
);
et.setOnQueryTextListener(new SearchView.OnQueryTextListener()
@Override
public boolean onQueryTextChange(String newText)
expListAdapter.getFilter().filter(newText);
cmAdapter.getFilter().filter(newText);
allAdapter.getFilter().filter(newText);
playlistAdapter.getFilter().filter(newText);
return false;
@Override
public boolean onQueryTextSubmit(String query)
return false;
);
return true;
