android屏幕保持唤醒

16lz 2021-12-18

方法 1: use PowerManager and WakeLock

AndroidManifest.xml权限:

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

程序中的代码:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
// in onResume() call mWakeLock.acquire(); ... // in onPause() call
mWakeLock.release();

方法 2: use the window flag FLAG_KEEP_SCREEN_ON

把下面的代码加入到程序onCreate方法中:

@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle); // Set keep screen on
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}
