Android ListView復雜使用方式簡單理解

android手機操作系統中，有許多應用比較復雜，對於初學者來說還需要在實踐中去加深對此的理解。在android ListVIEw的使用較為復雜一點，也就是配置其Adapter，Adapter有幾種，有ArrayAdapter,SimpleAdapter等，首先要生成一個ListView(當然可以使用ListActivity,此Activity整合了ListView)然後用Adapter來設定ListVIEw的顯示數據及布局方式，然後再來響應OnItemClick 事件，或者在ListActivity改寫onListItemClick 響應事件函數。看如下代碼演示了使用ListActivity：

import Java.util.ArrayList;  
import Java.util.HashMap;  
import Java.util.Map;  
import android.app.ListActivity;  
import android.os.Bundle;  
import android.view.VIEw;  
import android.widget.ListVIEw;  
import android.widget.SimpleAdapter; 

public class Test extends ListActivity {  
@Override  
protected void onListItemClick(ListView l, VIEw v, int position, long id) {  
// TODO Auto-generated method stub  
super.onListItemClick(l, v, position, id);  
this.setTitle(this.mModelData.get(position).get("type").toString());  
}  
SimpleAdapter adapter = null;  
private ArrayList<Map<String, Object>> mModelData = null;  
/** Called when the activity is first created. */  
@Override  
public void onCreate(Bundle savedInstanceState) {  
super.onCreate(savedInstanceState);  
initModelData();  
adapter = new SimpleAdapter
(this, mModelData, android.R.layout.two_line_list_item, 
new String[]{"name"}, new int[]{android.R.id.text1});  
this.setListAdapter(adapter);  
//setContentVIEw(R.layout.main);  
}  
public void initModelData()  
{  
mModelData = new ArrayList<Map<String, Object>>();  
Map<String, Object> item = new HashMap<String,Object>();  
item.put("name", "Linux");item.put("type", "OS");  
mModelData.add(item);  
Map<String, Object> item2 = new HashMap<String,Object>();  
item2.put("name", "android");item2.put("type", "Platform");  
mModelData.add(item2);  
Map<String, Object> item3 = new HashMap<String,Object>();  
item3.put("name", "Tomato");item3.put("type", "Fruit");  
mModelData.add(item3);  
}  
} 

下面代碼顯示了，使用android ListVIEw + Activity：

import android.app.Activity;  
import android.os.Bundle;  
import android.view.VIEw;  
import android.widget.AdapterVIEw;  
import android.widget.ArrayAdapter;  
import android.widget.ListVIEw;  
import android.widget.AdapterVIEw.OnItemClickListener;  
public class TestStringList extends Activity implements 
OnItemClickListener {  
@Override  
public void onItemClick(AdapterVIEw 

> arg0,   
VIEw arg1, int arg2, long arg3) {    
 
this.setTitle("You Click Item:" + String.valueOf(arg2));     
}    
private ListVIEw mListVIEw = null;    
@Override    
protected void onCreate(Bundle savedInstanceState) {    
// TODO Auto-generated method stub    
super.onCreate(savedInstanceState);    
mListVIEw = new ListVIEw(this);    
mListVIEw.setOnItemClickListener(this);    
ArrayAdapter<String> adapter = new ArrayAdapter<String> 
(this,android.R.layout.simple_list_item_checked,    
new String[]{"ItemA", "ItemB", "ItemC"});    
mListVIEw.setAdapter(adapter);    
this.setContentView(mListVIEw);    
}    
}
