在非锁屏的任意状态下监测HOME键

定义BroadcastReceiver 用于接收 action: android.intent.action.CLOSE_SYSTEM_DIALOGS

public class HomeKeyPressedReceiver extends BroadcastReceiver { private static final String TAG = "TestReceiver"; private static int count = 0; @Override public void onReceive(Context context, Intent intent) { String reason = intent.getStringExtra("reason"); Log.d(TAG, "HomeKeyPressedReceiver reason is " + reason); if ("homekey".equals(reason)) { Log.d(TAG, "homekey click count = " + count++); } } }

 

 注册receiver到系统中

<receiver android:label="HomeKeyPressedReceiver" android:name="HomeKeyPressedReceiver" android:enabled="true" android:exported="true"> <intent-filter> <category android:name="android.intent.category.DEFAULT" /> <action android:name="android.intent.action.BOOT_COMPLETE" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.CLOSE_SYSTEM_DIALOGS" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.SCREEN_ON" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.SCREEN_OFF" /> </intent-filter> </receiver>
