说明：

\-e/--es:传递String类型

\-ef：传递float类型

。。。。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>
