    //屏幕锁屏与解锁的通知不能写在清单文件中，要手动注册
        ScreenReceiver receiver = new ScreenReceiver();
        IntentFilter filter = new IntentFilter();
        filter.addAction("android.intent.action.SCREEN_ON");
        filter.addAction("android.intent.action.SCREEN_OFF");
        registerReceiver(receiver, filter);


屏幕状态的接收者：

public class ScreenReceiver extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        String action = intent.getAction();
        if("android.intent.action.SCREEN_ON".equals(action)){
            System.out.println("解锁了》》》》》》");
        }else if("android.intent.action.SCREEN_OFF".equals(action)){
            System.out.println("锁屏了》》》》》》");
        }
    }
}
