android之广播

类似ios里面的通知～，直接上代码

MainActivity.java

package com.example.test;

import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        Button testBtn = (Button)findViewById(R.id.button1);
        testBtn.setOnClickListener(new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                
                Intent intent = new Intent();
                intent.setAction("12345678");//这里给xml配置里面过滤用
                intent.putExtra("asd", "dddddddddddddddddddddddddddddddddddddd");
                
                sendBroadcast(intent);
            }
        });
    }
}

MyReceiver.Java

package com.example.test;

import android.R.string;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class MyReceiver extends BroadcastReceiver {

    public MyReceiver() {
        // TODO Auto-generated constructor stub
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

        String info = intent.getStringExtra("asd");
        
        Toast.makeText(context, info, Toast.LENGTH_LONG).show();
    }
}
