intent.setAction("cn.xhhkj.broadcast");
String receiverpermission = null;
broadcastReceiver resultReceiver = new FinalReceiver();
Handler scheduler = null;
String initialData = "中500万彩票，给你们发红包1万元";
sendOrderedbroadcast(intent, receiverpermission, resultReceiver, scheduler, Activity.RESULT_OK, initialData, null);
}
});
}
}
FinalReceiver.java
package cn.xhhkj.cyd;
import android.content.broadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
class FinalReceiver extends broadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String resultData = getResultData();
Toast.makeText(context, "final:"+resultData, Toast.LENGTH_SHORT).show();
}
}
由于篇幅有限，有序广播接收需要单独建个项目进行接收，在这里就不展示了。只展示一个
public class FarmerReceiver extends broadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String resultData = getResultData();
Toast.makeText(context, resultData, Toast.LENGTH_SHORT).show();
setResultData("郑州做app哪家好？");
}
}
