MainActivity

package com.zzw.server;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.EditText;public class MainActivity extends Activity {    EditText et1, et2;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        findViewById(R.id.button).setOnClickListener(new OnClickListener() {                        @Override            public void onClick(View v) {                init();            }        });    }    public void init() {        et1 = (EditText) findViewById(R.id.editText1);        et2 = (EditText) findViewById(R.id.editText2);        Intent intent = new Intent(MainActivity.this, TestServer.class);        int a = Integer.parseInt(et1.getText().toString());        int b = Integer.parseInt(et2.getText().toString());        int num[] = { a, b };        intent.putExtra(Canshu.KEY, num);        startService(intent);//开始    }    @Override    protected void onDestroy() {        super.onDestroy();        Intent intent = new Intent(MainActivity.this, TestServer.class);        stopService(intent);//结束    }    }

Server:

package com.zzw.server;import android.app.Service;import android.content.Intent;import android.os.IBinder;import android.util.Log;import android.widget.Toast;public class TestServer extends Service {    //开始只运行一次    @Override    public void onCreate() {        Log.d("=========", "我开始了");        super.onCreate();    }    @Override    public int onStartCommand(Intent intent, int flags, int startId) {        int num[] = intent.getIntArrayExtra(Canshu.KEY);        int sum = num[0] + num[1];        Toast.makeText(TestServer.this, sum + "", 1).show();        return super.onStartCommand(intent, flags, startId);    }    @Override    public IBinder onBind(Intent intent) {        // TODO Auto-generated method stub        return null;    }    @Override    public void onDestroy() {        Log.d("======", "我被干掉了");        super.onDestroy();    }}
