Ich habe den folgenden Code verwendet, aber keine Lösung gefunden.

MyReceiver.java:

    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    import android.util.Log;
    import android.widget.Toast;

    public class MyReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

     Log.v("onReceive", "Power button is pressed.");

     Toast.makeText(context, "power button clicked", Toast.LENGTH_LONG)
             .show();
    }

}

undMainActivity.java:

    import android.os.Bundle;
    import android.app.Activity;
    import android.view.Menu;

    public class MainActivity extends Activity {

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
        }

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            getMenuInflater().inflate(R.menu.activity_main, menu);
            return true;
        }
    }

undAndroidManifest.xml:

  <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver android:name=".MyReceiver">
    <intent-filter>
        <action android:name="android.intent.action.SCREEN_OFF"></action>
        <action android:name="android.intent.action.SCREEN_ON"></action>
        <action android:name="android.intent.action.ACTION_POWER_CONNECTED"></action>
        <action android:name="android.intent.action.ACTION_POWER_DISCONNECTED"></action>
         <action android:name="android.intent.action.ACTION_SHUTDOWN"></action>
    </intent-filter>
</receiver>
</application>
