Android之ListView设置

Android开发中，我们常使用到ListView视图，下面介绍ListView的几种使用方法。

主界面

首先，在主界面上添加几个按钮，用于界面跳转。

界面布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity"
android:orientation="vertical" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button1"
android:text="button1"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button2"
android:text="button2"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button3"
android:text="button3"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button4"
android:text="SimpleList"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button5"
android:text="TitleList"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button6"
android:text="IconList"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button7"
android:text="ColorList"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button8"
android:text="ArrayList"/>

<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="Button9"
android:text="test"/>

</LinearLayout>


源码：
package com.example.listviewdemo;

import android.os.Bundle;
import android.view.View;
import android.app.Activity;
import android.content.Intent;

public class MainActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

public void Button1(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, Activity01.class);
startActivity(intent);
}

public void Button2(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, Activity02.class);
startActivity(intent);
}

public void Button3(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, Activity03.class);
startActivity(intent);
}

public void Button4(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, SimpleList.class);
startActivity(intent);
}

public void Button5(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, TitleList.class);
startActivity(intent);
}

public void Button6(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, IconList.class);
startActivity(intent);
}

public void Button7(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, ColorList.class);
startActivity(intent);
}

public void Button8(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, ArrayList.class);
startActivity(intent);
}

public void Button9(View v)
{
Intent intent = new Intent();
intent.setClass(MainActivity.this, MyTest.class);
startActivity(intent);
}
}

使用ListView设置界面

package com.example.listviewdemo;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class Activity01 extends Activity
{
private ListView listView;

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

listView = new ListView(this);
listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1,getData()));
setContentView(listView);
}

private List<String> getData(){

List<String> data = new ArrayList<String>();
data.add("测试数据1");
data.add("测试数据2");
data.add("测试数据3");
data.add("测试数据4");

return data;
}
}


效果

使用SimpleAdapter设置界面

package com.example.listviewdemo;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.SimpleAdapter;

public class Activity02 extends ListActivity
{

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

SimpleAdapter adapter = new SimpleAdapter(this,getData(),R.layout.vlist,
new String[]{"title","info","img"},
new int[]{R.id.title,R.id.info,R.id.img});
setListAdapter(adapter);
}

private List<Map<String, Object>> getData() {
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

Map<String, Object> map = new HashMap<String, Object>();
map.put("title", "标题1");
map.put("info", "内容1");
map.put("img", R.drawable.icon_marka);
list.add(map);

map = new HashMap<String, Object>();
map.put("title", "标题2");
map.put("info", "内容2");
map.put("img", R.drawable.icon_markb);
list.add(map);

map = new HashMap<String, Object>();
map.put("title", "标题3");
map.put("info", "内容3");
map.put("img", R.drawable.icon_markc);
list.add(map);

return list;
}
}

vlist布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
