类似ios里面的通知～，直接上代码

MainActivity.java

 1 package com.example.test;
 2 
 3 import android.app.Activity;
 4 import android.app.Notification;
 5 import android.app.NotificationManager;
 6 import android.app.PendingIntent;
 7 import android.content.Context;
 8 import android.content.Intent;
 9 import android.os.Bundle;
10 import android.view.View;
11 import android.view.View.OnClickListener;
12 import android.widget.Button;
13 
14 public class MainActivity extends Activity {
15 
16     @Override
17     protected void onCreate(Bundle savedInstanceState) {
18         super.onCreate(savedInstanceState);
19         setContentView(R.layout.activity_main);
20         
21         Button testBtn = (Button)findViewById(R.id.button1);
22         testBtn.setOnClickListener(new OnClickListener() {
23             
24             @Override
25             public void onClick(View v) {
26                 // TODO Auto-generated method stub
27                 
28                 Intent intent = new Intent();
29                 intent.setAction("12345678");//这里给xml配置里面过滤用
30                 intent.putExtra("asd", "dddddddddddddddddddddddddddddddddddddd");
31                 
32                 sendBroadcast(intent);
33             }
34         });
35     }
36 }

MyReceiver.Java

 1 package com.example.test;
 2 
 3 import android.R.string;
 4 import android.content.BroadcastReceiver;
 5 import android.content.Context;
 6 import android.content.Intent;
 7 import android.widget.Toast;
 8 
 9 public class MyReceiver extends BroadcastReceiver {
10 
11     public MyReceiver() {
12         // TODO Auto-generated constructor stub
13     }
14 
15     @Override
16     public void onReceive(Context context, Intent intent) {
17         // TODO Auto-generated method stub
18 
19         String info = intent.getStringExtra("asd");
20         
21         Toast.makeText(context, info, Toast.LENGTH_LONG).show();
22     }
23 }
