MainActivity.java
package com.qf.day22_broadcastreceiver_demo1;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
//发送广播
public void MySendClick(View v){
// Intent intent = new Intent(MainActivity.this, MyBroadCastReceiver01.class);
Intent intent = new Intent();
intent.setAction("com.qq.weixin");
intent.putExtra("str", "疯狗咬人");
//发送普通的广播
sendBroadcast(intent);
}
}
MyBroadCastReceiver01.java
package com.qf.day22_broadcastreceiver_demo1;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class MyBroadCastReceiver01 extends BroadcastReceiver{
/**
* 就一个生命周期 普通广播10s
*/
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
}
}
MyBroadCastReceiver02.java
MyBroadCastReceiver03.java
与上一个代码一样
结果:三个广播接受者 根据priority大小先后弹吐司
