broadcastReceiver无法正常工作且没有制作任何日志,请帮我解决这个问题.

解决方法 嘿尝试使用动态调用广播,我尝试了它将乖乖工作…

public class MainActivity extends Activity {    //Create broadcast object    broadcastReceiver mybroadcast = new broadcastReceiver() {            //When Event is published,onReceive method is called        @OverrIDe        public voID onReceive(Context context,Intent intent) {            // Todo auto-generated method stub            Log.i("[broadcastReceiver]","MyReceiver");            if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {                Log.i("[broadcastReceiver]","Screen ON");            }            else if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {                Log.i("[broadcastReceiver]","Screen OFF");            }        }    };    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_main);        registerReceiver(mybroadcast,new IntentFilter(Intent.ACTION_SCREEN_ON));        registerReceiver(mybroadcast,new IntentFilter(Intent.ACTION_SCREEN_OFF));    }}
