螢幕關閉使用攝像頭（Android設備）時

Question

有沒有什麼辦法來保持屏幕清醒（不希望它關閉）當我預覽相機？

謝謝！

Answer 1

最簡單的方法是使用WakeLock

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); 
PowerManager.WakeLock wakeLock = pm.newWakeLock(
     pm.SCREEN_DIM_WAKE_LOCK, "My wakelook"); 
// This will make the screen and power stay on 
// This will release the wakelook after 1000 ms 
wakeLock.acquire(1000); 

// Alternative you can request and/or release the wakelook via: 
// wakeLock.acquire(); wakeLock.release(); 

Answer 2

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN | 
    WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, 
        WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
