androidx.appcompat.widget.SearchView cannot be cast to android.widget.SearchView

Question

When I launch my app the following error is thrown:

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.app, PID: 5513 java.lang.ClassCastException: androidx.appcompat.widget.SearchView cannot be cast to android.widget.SearchView at com.example.app.MainActivity.onCreateOptionsMenu(MainActivity.java:169)

I am trying to use a searchview in the app bar.

Answer 1

The solution is very similar to this one except it is related to Android X instead.

So you just need to change import android.widget.SearchView; to:

import androidx.appcompat.widget.SearchView;
