在列表视图项点击Open XML文档 [英] Open xml file on listview item click

问题描述

我想打开一个新的XML文件或文本文件，当用户在列表视图中选择一个项目。下面是我的code： 原来的问题 - >

I'm trying to open a new xml or text file when the user select an item on listview. Below is my code: Original Question-->

MainActivity.java

MainActivity.java

package com.example.listview;

import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class MainActivity extends ListActivity {
  public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
        "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
        "Linux", "OS/2" };
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1, values);
    setListAdapter(adapter);
  }

  @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
    String item = (String) getListAdapter().getItem(position);
    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
  }
} 

在 onListItemClick 触发我想打开里面有一些数据的XML文件。 当机器人被选中android.xml，显示出来。 当iPhone时iphone.xml，显示了。

When onListItemClick is triggered I want to open xml file which has some data. When "Android" is selected android.xml, shows up. When "iPhone" is selected iphone.xml, shows up.

这似乎是很好的教程开始。

Which seems to be good tutorial for a start.

您不要打开XML。您导航到基于列表项点击位置的不同的活动。每个活动都会有自己的布局设置。

You don't open a xml. You navigate to a different activity based on the position of List item click. Each activity will have its own layout set.

下面应该工作

try
{
String val = values[postion];
Class ourClass  = Class.forName("com.example.listview."+val);
Intent intent = new Intent(MainActivity.this,ourClass);
startActivity(intent);
}catch(Exception e){
      e.prinStacktrace();
}

请确保您为活动清单文件中的条目

Make sure you make an entry for Activities in manifest file

编辑：

public class MainActivity extends ListActivity {
   String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
        "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
        "Linux", "OS/2" };
  public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1, values);
    setListAdapter(adapter);
  }

  @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
    try
    {
    String val = values[postion];
    Class ourClass  = Class.forName("com.example.listview."+val);
    Intent intent = new Intent(MainActivity.this,ourClass);
    startActivity(intent);
    }catch(Exception e){
          e.prinStacktrace();
    }
  }
}
