Android如何保持屏幕常亮

在不同的生命周期调用不用的WakeLock函数可以使系统正常运行(如果不调用WakeLock.release，则屏幕会一直常亮)

首先添加权限：

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

实现代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 public class test extends Activity { PowerManager powerManager = null ; WakeLock wakeLock = null ; @Override protected void onCreate(Bundle savedInstanceState) { super .onCreate(savedInstanceState); this .setContentView(R.layout.main); this .powerManager = (PowerManager) this .getSystemService(Context.POWER_SERVICE); this .wakeLock = this .powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "My Lock" ); } @Override protected void onResume() { super .onResume(); this .wakeLock.acquire(); } @Override protected void onPause() { super .onPause(); this .wakeLock.release(); } }
