利用IntentService实现在broadcastreceiver中比较耗时的任务

============================== 在主界面手动发送广播
package com.huawei.tj.bi.monitor;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.view.View;

import android.widget.Button;

public class MainActivity extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

       

        Button btn = (Button) findViewById(R.id.btn);

        btn.setOnClickListener(new View.OnClickListener() {

              

               @Override

               public void onClick(View arg0) {

                    Intent intent = new Intent();

                    intent.setAction("com.qlj.myReceiver");

                    sendBroadcast(intent);

               }

          });

    }

}

========================================广播接受者启动intentService
package com.huawei.tj.bi.monitor;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

public class MyReceiver extends BroadcastReceiver {

     @Override

     public void onReceive(Context arg0, Intent arg1) {

          Intent intent = new Intent(arg0,SmsService.class);

          intent.putExtra("key1", "value1");

          intent.putExtra("key2", "value2");

          intent.putExtra("key3", "value3");

          arg0.startService(intent);

     }

}

=====================================IntentService 中启动线程完成耗时任务 

package com.huawei.tj.bi.monitor;

import android.app.IntentService;

import android.content.Intent;

import android.util.Log;

public class SmsService extends IntentService
{

        public SmsService()
{

               super("com.huawei.tj.bi.monitor.SmsService" );

       }

        @Override

        protected void onHandleIntent(Intent
intent) {

               final String
value1 = (String) intent.getExtras().get ("key1" );

               final String
value2 = (String) intent.getExtras().get ("key2" );

               final String
value3 = (String) intent.getExtras().get ("key3" );

               //Toast.makeText(getApplicationContext(), value1+value2+value3,
1).show();

               new Thread(){

                      public void run()
{

                           Log. i("xxxxxxxx",
value1+value2+value3);

                            try {

                                  Thread. sleep(20000);

                           } catch (InterruptedException
e) {

                                   // TODO Auto-generated
catch block

                                  e.printStackTrace();

                           }

                            //Toast.makeText(getApplicationContext(),
value1+value2+value3+"--after", 1).show();

                           Log. i("xxxxxxxx",
value1+value2+value3+ "--after");

                     };

              }.start();

              

       }

}
