做了一个可以查询飞机航班、火车班次的小应用
做得很粗糙，代码量也很少，数据通过调用web service得到。

TrainActivity.java用于输入起点站、终点站，并将输入的值传入下一个Activity

package cn.salesuite.layout;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;/** * @author Tony Shen * */public class TrainActivity extends Activity{int REQUEST_CODE=2;Button queryButton;  //查询按钮    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {    setTitle("火车班次查询");        super.onCreate(savedInstanceState);        setContentView(R.layout.train);                queryButton = (Button) findViewById(R.id.query);        queryButton.setOnClickListener(queryListener);    }// query按钮监听器    OnClickListener queryListener = new OnClickListener() {public void onClick(View v) {CharSequence firstStationValue = ((EditText) findViewById(R.id.firstStation)).getText();CharSequence lastStationValue = ((EditText) findViewById(R.id.lastStation)).getText();String temp = firstStationValue.toString() + "," + lastStationValue.toString();Intent intent = new Intent(TrainActivity.this, ListTrainActivity.class);intent.setData(Uri.parse(temp));            startActivityForResult(intent, REQUEST_CODE);//以传递参数的方式跳转到下一个Activity}};}

ListTrainActivity.java用于显示所有的查询出来的火车航班，通过dom4j来解析xml

飞机航班的做法很类似，下面上效果图
