Android之ListView設置

編輯：關於Android編程

Android開發中，我們常使用到ListView視圖，下面介紹ListView的幾種使用方法。

 

主界面

首先，在主界面上添加幾個按鈕，用於界面跳轉。

界面布局：

 

源碼：

 

 

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設置界面

 

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(this, android.R.layout.simple_expandable_list_item_1,getData()));
        setContentView(listView);
	}
	
	private List getData(){
        
        List data = new ArrayList();
        data.add("測試數據1");
        data.add("測試數據2");
        data.add("測試數據3");
        data.add("測試數據4");
        
        return data;
    }
}

	@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> getData() {
        List> list = new ArrayList>();
 
        Map map = new HashMap();
        map.put("title", "標題1");
        map.put("info", "內容1");
        map.put("img", R.drawable.icon_marka);
        list.add(map);
        
        map = new HashMap();
        map.put("title", "標題2");
        map.put("info", "內容2");
        map.put("img", R.drawable.icon_markb);
        list.add(map);
        
        map = new HashMap();
        map.put("title", "標題3");
        map.put("info", "內容3");
        map.put("img", R.drawable.icon_markc);
        list.add(map);
