。。。。其余同上，不同类型不能交互使用

例子：

C:\Users\yangrh2>adb shell am broadcast -a com.example.mybroadcast.MainActivity
--ef "int" 1.5f
Broadcasting: Intent { act=com.example.mybroadcast.MainActivity (has extras) }
Broadcast completed: result=0

类文件：

package com.example.mybroadcast;

import Android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;

public class MyReceiver extends BroadcastReceiver {

 public MyReceiver() {
  Log.e("test", "------------------------------");
 }

 @Override
 public void onReceive(Context arg0, Intent arg1) {
  Log.e("test", "--------------start broadcast---------------");
  // TODO Auto-generated method stub
  Toast.makeText(arg0,
    "接收到Intent的Action为：" + arg1.getAction() + "\n消息内容是："+arg1.getExtras()+
    arg1.getStringExtra("string")+"+add:"+arg1.getFloatExtra("int", 1.0f), Toast.LENGTH_LONG).show();
 }
}

Manifest：

        </activity>

        <receiver android:name=".MyReceiver" >
            <intent-filter>
                <action android:name="com.example.mybroadcast.MainActivity" >                ——————这里的action就是我们am broadcast -a +然后填写的内容act，
                </action>
            </intent-filter>
        </receiver>
    </application>
