点击一整行，更换radiobutton选择。

xml代码：

view plaincopy to clipboardprint?
<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/layout" 
    android:orientation="horizontal" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    > 
   <TextView  android:id="@+id/list_text" 
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:layout_centerVertical="true" 
    /> 
   <ImageView android:id="@+id/list_radioImg" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentRight="true"/> 
</RelativeLayout> 

java代码：

view plaincopy to clipboardprint?
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.view.View; 
import android.widget.ListView; 
import android.widget.SimpleAdapter; 
import android.widget.Toast; 
public class listRadioBtn extends ListActivity { 
    /** Called when the activity is first created. */ 
    private int balanceIndex = 0; 
    SimpleAdapter adapter; 
    List<Map<String, Object>> list; 
     
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
         
        adapter= new SimpleAdapter(this,getData(),R.layout.main,new String[]{"text","img"},new int[]{R.id.list_text,R.id.list_radioImg});  
         
        setListAdapter(adapter); 
    } 
         
        private List<Map<String, Object>> getData(){ 
             list = new ArrayList<Map<String, Object>>(); 
            Map<String, Object> map_day = new HashMap<String, Object>();  
            map_day.put("text", "白天");   
            map_day.put("img", R.drawable.setlist_radio_on);             
            list.add(map_day); 
             
            Map<String, Object> map_clody = new HashMap<String, Object>();  
            map_clody.put("text", "阴天");   
            map_clody.put("img", R.drawable.setlist_radio_off);              
            list.add(map_clody);  
             
            Map<String, Object> map_clo = new HashMap<String, Object>();  
            map_clo.put("text", "微风");   
            map_clo.put("img", R.drawable.setlist_radio_off);            
            list.add(map_clo);  
             
            return list; 
        } 
         
        protected void onListItemClick(ListView arg0, View arg1, int arg2, long arg3) { 
         Toast t = Toast.makeText(this, ""+list.get(arg2).get("text"), Toast.LENGTH_LONG); 
         t.show(); 
           
             ChangeRadioImg(balanceIndex,false); 
             ChangeRadioImg(arg2,true); 
             balanceIndex=arg2;    
              
             list.get(arg2).get("text"); 
         } 
         
        private void ChangeRadioImg(int selectedItem, boolean b) { 
            SimpleAdapter la = adapter;  
            HashMap<String, Object> map = (HashMap<String, Object>)la.getItem(selectedItem);   
            if(b) 
                map.put("img", R.drawable.setlist_radio_on); 
            else 
                map.put("img", R.drawable.setlist_radio_off); 
           la.notifyDataSetChanged(); 
             
        } 
        
} 

二

另一个简单办法：

android系统中，提供了这样的方法

mylist.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

程序主代码：

view plaincopy to clipboardprint?
protected void onCreate(Bundle savedInstanceState) { 
        // TODO Auto-generated method stub 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.list_layout); 
        contentString = new String[] {  
                "示例", "透明动画", 
                "伸缩动画", "移动动画", 
                "旋转动画", "透明_伸缩", 
                "透明_移动", "透明_旋转" 
                 
    }; 
        arrayAdapter = new ArrayAdapter<String>(this, 
                android.R.layout.simple_list_item_single_choice, 
                contentString); 
        mylist = (ListView) findViewById(R.id.ListView01); 
        mylist.setAdapter(arrayAdapter); 
        mylist.setOnItemClickListener(this); 
        mylist.setOnItemSelectedListener(this); 
        mylist.setChoiceMode(ListView.CHOICE_MODE_SINGLE); 
        mylist.setItemChecked(0, true); 
    } 

其中，android.R.layout.simple_list_item_single_choice在framework/base/core/res/res/layout目录下，可参见源码

三 多选框

view plaincopy to clipboardprint?
import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.AdapterView.OnItemClickListener; 
import android.widget.AdapterView.OnItemSelectedListener; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 
public class ListCheckbox extends Activity implements OnItemClickListener,OnItemSelectedListener{ 
    private String contentString[]; 
    ArrayAdapter arrayAdapter; 
    ListView mylist; 
    protected void onCreate(Bundle savedInstanceState) { 
        // TODO Auto-generated method stub 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main); 
        contentString = new String[] {  
                "示例", "透明动画", 
                "伸缩动画", "移动动画", 
                "旋转动画", "透明_伸缩", 
                "透明_移动", "透明_旋转" 
                 
    }; 
        arrayAdapter = new ArrayAdapter<String>(this, 
                android.R.layout.simple_list_item_multiple_choice,//.simple_list_item_single_choice, 
                contentString); 
        mylist = (ListView) findViewById(R.id.ListView01); 
        mylist.setAdapter(arrayAdapter); 
        mylist.setOnItemClickListener(this); 
        mylist.setOnItemSelectedListener(this); 
        mylist.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);//.CHOICE_MODE_SINGLE); 
        mylist.setItemChecked(0, true); 
    } 
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,long arg3) { 
        mylist.setItemChecked(arg2, true); 
         
    } 
    public void onNothingSelected(AdapterView<?> arg0) { 
        // TODO Auto-generated method stub 
         
    } 
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
        // TODO Auto-generated method stub 
         
    }     
}
