am broadcast -a 过滤action -e/--es.........

参数说明如下：

<INTENT> specifications include these flags and arguments:
    [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>]
    [-c <CATEGORY> [-c <CATEGORY>] ...]
    [-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...]
    [--esn <EXTRA_KEY> ...]
    [--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...]
    [--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...]
    [--el <EXTRA_KEY> <EXTRA_LONG_VALUE> ...]
    [--ef <EXTRA_KEY> <EXTRA_FLOAT_VALUE> ...]
    [--eu <EXTRA_KEY> <EXTRA_URI_VALUE> ...]
    [--ecn <EXTRA_KEY> <EXTRA_COMPONENT_NAME_VALUE>]
    [--eia <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]]
    [--ela <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]]
    [--efa <EXTRA_KEY> <EXTRA_FLOAT_VALUE>[,<EXTRA_FLOAT_VALUE...]]
    [-n <COMPONENT>] [-f <FLAGS>]
    [--grant-read-uri-permission] [--grant-write-uri-permission]
    [--debug-log-resolution] [--exclude-stopped-packages]
    [--include-stopped-packages]
    [--activity-brought-to-front] [--activity-clear-top]
    [--activity-clear-when-task-reset] [--activity-exclude-from-recents]
    [--activity-launched-from-history] [--activity-multiple-task]
    [--activity-no-animation] [--activity-no-history]
    [--activity-no-user-action] [--activity-previous-is-top]
    [--activity-reorder-to-front] [--activity-reset-task-if-needed]
    [--activity-single-top] [--activity-clear-task]
    [--activity-task-on-home]
    [--receiver-registered-only] [--receiver-replace-pending]
    [--selector]
    [<URI> | <PACKAGE> | <COMPONENT>]

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>
