Android 監聽螢幕喚醒和關閉的廣播

 今天希望應用程式的服務運行時，可以監聽到螢幕的喚醒。繼續百度學習法，連同監聽閉幕關閉也一同學習了。

 

此種情況需要動態註冊系統廣播。在AndroidManifest.xml中靜態註冊的實際運行中無效。

 

private ScreenStatusReceiver mScreenStatusReceiver;

 

在需要的地方調用如下函數：

    private void registSreenStatusReceiver() {        mScreenStatusReceiver = new ScreenStatusReceiver();          IntentFilter screenStatusIF = new IntentFilter();          screenStatusIF.addAction(Intent.ACTION_SCREEN_ON);          screenStatusIF.addAction(Intent.ACTION_SCREEN_OFF);          registerReceiver(mScreenStatusReceiver, screenStatusIF);      }

 

使用結束後，登出：

unregisterReceiver(mScreenStatusReceiver); 

 

ScreenStatusReceiver類：

    class ScreenStatusReceiver extends BroadcastReceiver {        String SCREEN_ON = "android.intent.action.SCREEN_ON";        String SCREEN_OFF = "android.intent.action.SCREEN_OFF";         @Override        public void onReceive(Context context, Intent intent) {            if (SCREEN_ON.equals(intent.getAction())) {                 Log.w("ppp","ppp-螢幕亮了");            }            else if (SCREEN_OFF.equals(intent.getAction())) {
                 Log.w("ppp","ppp-螢幕暗了");            }        }    }
