Cannot instantiate class android.support.v7.widget.SearchView

Question

Please somebody help me! I trying add appcompat search view to my project. Unsuccessfully. When I change android.support.v7.widget.SearchView to SearchView (API > 10) everything's fine.

This my menu res:

<item android:id="@+id/action_search"
    android:title="@string/search_view_title"
    android:icon="@drawable/action_search"
    sabd:showAsAction="always|collapseActionView"
    sabd:actionViewClass="android.support.v7.widget.SearchView" />

This how I try to use SeachView:

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.teach, menu);
        mSearchItem = menu.findItem(R.id.action_search);
        mSearchItem.setVisible(true);
        mSearchView = (SearchView) MenuItemCompat.getActionView(mSearchItem);
        mSearchView.setQueryHint(getString(R.string.search_view_hint));
        mSearchView.setOnQueryTextListener(this);
    }

This my manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="ru.rgups.time"
    android:versionCode="1"

        <activity

            android:uiOptions="splitActionBarWhenNarrow">

        </activity>

        <receiver android:name="ru.rgups.time.receiver.HomeWorkNotificationReceiver">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>
        </receiver>

    </application>

</manifest>

And this what I see in logs:

Answer 1

I had a similar probably that appeared on my release builds but not my debug builds when switching over to the v21 support library. Turned out to be an obfuscation problem, and adding this line to my proguard-rules.txt file fixed it:

-keep class android.support.v7.widget.SearchView { *; }

Answer 2

I had the same issue when I was using Android Studio and Gradle to build my project. I would like to add a SearchView of v7 compat.

The solution is to change gradle plugin version from 0.9.1 or others to 0.9.0. It is a temporary way I found. It maybe a bug of gradle plugin. Hope that helps.

    dependencies {
        classpath "com.android.tools.build:gradle:0.9.0"
    }

Answer 3

Problem was in bad v7 support library. After update everything fine.
