android.widget.SearchView cannot be cast to android.support.v7.widget.SearchView

Question

I\'m not unsure of why I\'m getting this error. Here\'s the menu in question:

Answer 1

Try adding this:

MenuItem menuItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(menuItem);

It worked for me.

Answer 2

Add this to your build.gradle file

implementation 'com.android.support:appcompat-v7:21.0.3'

and then add this

android.support.v7.widget.SearchView 

instead of

// remove or replace this line 
import android.widget.SearchView;

in your activity file

Answer 3

you should use these imports instead of using the support library imports

import android.app.SearchManager;
import android.widget.SearchView;
import android.widget.SearchView.OnQueryTextListener;

Just to keep in mind that the minimum SDK is marked as 14

Answer 4

Find import android.widget.SearchView; in your imports and replace it with import android.support.v7.widget.SearchView

Answer 5

According to the documentation, In the onCreateOptionsMenu use

MenuItem menuItem = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView) menuItem.getActionView();

ie:use the menu item directly to call getActionView() method

instead of

MenuItem menuItem = menu.findItem(R.id.action_search);
        SearchView searchView = MenuItemCompat.getActionView(menuItem);

or

searchView = (SearchView) menu.findItem(R.id.action_search);

becouse both are deprecated

Answer 6

For me i have only changed

app:actionViewClass="android.widget.SearchView"

Insted of

app:actionViewClass="androidx.appcompat.widget.SearchView"
