- 有序广播
- 不可被打断
- 无序广播
- 其他广播接受者可以修改在发送或者拦截发送
- 粘性广播
- 弃用 将广播放入广播池中等候处理为止

MainActivity.java
package com.qf.day22_broadcastreceiver_demo3;import android.app.Activity;import android.content.BroadcastReceiver;import android.content.Context;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); } public void MySendClick(View v){ Intent intent = new Intent(); intent.setAction("cctv.hlj.beijin"); intent.putExtra("str", "iphone7"); //普通广播 //sendBroadcast(intent); //有序广播1 //sendOrderedBroadcast(intent, null); //有序广播2 并设置最终接受者 不管abortBroadcast();依然最后收到 sendOrderedBroadcast(intent, null,new BroadcastReceiver(){ @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub } }, null, 0, null, null); }} MyBroadCastReceiver01.java
package com.qf.day22_broadcastreceiver_demo3;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.widget.Toast;public class MyBroadCastReceiver01 extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub if(intent!=null){ String str = intent.getStringExtra("str"); Toast.makeText(context, "===111=="+str, 0).show(); } }} MyBroadCastReceiver02.java
与上代码差不多MyBroadCastReceiver03.java:
package com.qf.day22_broadcastreceiver_demo3;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.widget.Toast;public class MyBroadCastReceiver03 extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub if(intent!=null){ String str = intent.getStringExtra("str"); Toast.makeText(context, "===333=="+str, 0).show(); } abortBroadcast();//中断广播 }} 结果：只有MyBroadCastReceiver03吐司 还有最终接受者收到信息
