Android 屏幕常亮

android 实现屏幕常亮代码:

在onCreate方法里获取锁屏服务

    PowerManager powerManager = null;    WakeLock wakeLock = null;    @SuppressWarnings("deprecation")    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        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();        SDKWrapper.getInstance().onResume();        this.wakeLock.acquire();    }    @Override    protected void onPause() {        super.onPause();        SDKWrapper.getInstance().onPause();        this.wakeLock.release();    }    @Override    protected void onDestroy() {        super.onDestroy();        SDKWrapper.getInstance().onDestroy();        this.wakeLock.release(); //解除保持唤醒    }

还需要添加权限:

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