Keep screen on
1.在Activity中添加
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
2.界面布局文件中直接設置
android:keepScreenOn="true"
3.使用WAKE_LOCK
<uses-permission android:name="android.permission.WAKE_LOCK" /> PowerManager.WakeLock mPowerManager = (PowerManager) getSystemService(Context.POWER_SERVICE); mCpuWakeLock = mPowerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP|PowerManager.ON_AFTER_RELEASE, "wake_up"); // mCpuWakeLock.setReferenceCounted(false); //是否需計算鎖的數量 mCpuWakeLock.acquire(); mCpuWakeLock.release(); /* PARTIAL_WAKE_LOCK: 保持CPU 運轉，屏幕和鍵盤燈可以關閉。 SCREEN_DIM_WAKE_LOCK： 保持CPU 運轉，保持屏幕顯示，但可以變暗，允許鍵盤燈關閉。 SCREEN_BRIGHT_WAKE_LOCK：保持CPU 運轉，允許保持屏幕高亮顯示，允許鍵盤燈關閉。 FULL_WAKE_LOCK： 保持CPU 運轉，保持屏幕和鍵盤燈都高亮顯示。 ACQUIRE_CAUSES_WAKEUP： 當獲取鎖后，立刻亮屏，典型地使用在通知中，以讓用戶立刻查看。 ON_AFTER_RELEASE： 在釋放鎖（release()）后，手機屏幕仍會繼續亮一會兒。 */
