首先创建一个java类继承BroadcastReceiver类
package com.example.service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class MyBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO: This method is called when the BroadcastReceiver is receiving
// an Intent broadcast.
String msg=intent.getStringExtra("msg");//获得广播信息
Toast.makeText(context,msg,Toast.LENGTH_SHORT).show();
}
}
Mainactivity中添加如下语句进行数据的广播 Intent it=new Intent();
it.setAction("android.intent.action.EDIT");//自定义地址
//it.setComponent(new ComponentName("com.example.service", //此段内容用于Android8.0无法接收广播的情况参数1是自定义广播的包名，
// "com.example.service.MyBroadcastReceiver"));//参数2是自定义广播的路径
it.putExtra("msg","广播已接收"); MainActivity.this.sendBroadcast(it);
在AndroidMainfest.xml中注册，在<application></application>中添加
<receiver
android:name=".MyBroadcastReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.EDIT"/>
</intent-filter>
</receiver>
