Answer 1

try to use the same activity name from the calling activity, you used SearchActivity to show the search result, try to use the same activity name

<activity android:name=".MainActivity">
          <intent-filter>
             <action android:name="android.intent.action.MAIN" />
             <category android:name="android.intent.category.LAUNCHER" />

          </intent-filter>
            <meta-data
              android:name="android.app.default_searchable"
              android:value=".SearchActivity" />
</activity>

Answer 2

Your Activity is named SearchActivity , but you declared SearchResultsActivity in manifest:

<meta-data
     android:name="android.app.default_searchable"
     android:value=".SearchResultsActivity" /> 

From the docs :

To declare the searchable activity for an activity's search dialog, add a element inside the respective activity's element. The element must include the android:value attribute that specifies the searchable activity's class name and the android:name attribute with a value of "android.app.default_searchable".

Answer 3

You can also do this programmatically.

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) { // this is triggered when you press the key search from keyboard.
            return true;
        }

        @Override
        public boolean onQueryTextChange(String newText) { // this is triggered when you change your search text. 
            return true;
        }
    });
