問題描述

這里缺少什么？ 我想將設備從睡眠中喚醒，但是什么也沒發生。 我當然不想阻止睡眠。 

final Handler handler = new Handler(); 
Runnable runable = new Runnable() { 
            @Override 
            public void run() { 
            try{
                wl = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK |  PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
                         wl.acquire();
                         wl.release();

                Log.v("INTERVAL: ", "NOW" );
                handler.postDelayed(this, 5000);
            }
            catch (Exception e) {
                        // TODO: handle exception
            }
     }

wl.release（）; 僅在作業完成時才應調用。 如果您立即獲取（）和釋放（），將不會發生任何事情。 嘗試這個： 

 final Handler handler = new Handler(); 
 Runnable runnable = new Runnable() { 
        @Override 
        public void run() { 
            try{


                 wl = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
                 wl.acquire();

                //PUT HERE THE CODE YOU WANNA EXECUTE

                 wl.release();

            }
            catch (Exception e) {
                // TODO: handle exception
            } }
      };


       Log.v("INTERVAL: ", "NOW" );
       handler.postDelayed(runnable, 5000);

另外，請確保將權限放在清單文件中： 

 <uses-permission android:name="android.permission.WAKE_LOCK" />
