接收系统广播事件，屏幕在三种状态（开屏、锁屏、解锁）之间变换的时候，系统都会发送广播，我们只需要监听这些广播即可。
代码如下：

private ScreenBroadcastReceiver mScreenReceiver;private class ScreenBroadcastReceiver extends BroadcastReceiver {    private String action = null;      @Override    public void onReceive(Context context, Intent intent) {        action = intent.getAction();        if (Intent.ACTION_SCREEN_ON.equals(action)) {                       // 开屏        } else if (Intent.ACTION_SCREEN_OFF.equals(action)) {             // 锁屏        } else if (Intent.ACTION_USER_PRESENT.equals(action)) {             // 解锁        }    }}private void startScreenBroadcastReceiver() {    IntentFilter filter = new IntentFilter();    filter.addAction(Intent.ACTION_SCREEN_ON);    filter.addAction(Intent.ACTION_SCREEN_OFF);    filter.addAction(Intent.ACTION_USER_PRESENT);    context.registerReceiver(mScreenReceiver, filter);}
