效果图：


设置单选列表只需 AlertDialog.Builder里面的setSingleChoiceItems 来设置即可
实现步骤如下：
第一步：用来显示列表内容的
res/values/array.xml

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <string-array name="hobby"> 
        <item>篮球</item> 
        <item>足球</item> 
        <item>排球</item> 
    </string-array> 
</resources>  
第二步：还是定义一个输入框和一个按钮
res/layout/single_choice_dialog_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
  xmlns:android=" http://schemas.android.com/apk/res/android " 
  android:orientation="vertical" 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content"> 
  <EditText android:id="@+id/editText" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="这是一个单选列表对话框" 
  /> 
  <Button android:id="@+id/button" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="显示单选列表对话框" 
  /> 
</LinearLayout>
第三步：
产生一个单选列表对话框，首先需要new 一个AlertDialog.Builder作为对话框内容的载体，然后通过setSingleChoiceItems将
builder与array.xml中的数据关联，需要通过DialogInterface.OnClickListener对列表单选单击事件进行处理，
为了保存单选列表项中的选中数据，需要单独写一个类，且类中需要加一个选中了哪一个列表项的属性which,
代码如下
src/com/dialog/activity/SingChoiceDialogActivity.java

package com.dialog.activity; 
 
import android.app.Activity; 
import android.app.AlertDialog; 
import android.app.Dialog; 
import android.app.AlertDialog.Builder; 
import android.content.DialogInterface; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
 
public class SingChoiceDialogActivity extends Activity { 
     
    private final int SING_CHOICE_DIALOG = 1; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.single_choice_dialog_layout); 
         
        Button button = (Button) findViewById(R.id.button); 
        View.OnClickListener listener = new View.OnClickListener() { 
             
            @Override 
            public void onClick(View view) { 
                showDialog(SING_CHOICE_DIALOG); 
            } 
        }; 
        button.setOnClickListener(listener); 
    } 
     
    @Override 
    protected Dialog onCreateDialog(int id) { 
        Dialog dialog = null; 
        switch(id) { 
            case SING_CHOICE_DIALOG: 
                Builder builder = new AlertDialog.Builder(this); 
                builder.setIcon(R.drawable.basketball); 
                builder.setTitle("体育爱好"); 
                final ChoiceOnClickListener choiceListener =  
                    new ChoiceOnClickListener(); 
                builder.setSingleChoiceItems(R.array.hobby, 0, choiceListener); 
                 
                DialogInterface.OnClickListener btnListener =  
                    new DialogInterface.OnClickListener() { 
                        @Override 
                        public void onClick(DialogInterface dialogInterface, int which) { 
                             
                            EditText editText = (EditText) findViewById(R.id.editText); 
                            int choiceWhich = choiceListener.getWhich(); 
                            String hobbyStr =  
getResources().getStringArray(R.array.hobby)[choiceWhich];
                            editText.setText("你选择了  " + hobbyStr); 
                        } 
                    }; 
                builder.setPositiveButton("确定", btnListener); 
                dialog = builder.create(); 
                break; 
        } 
        return dialog; 
    } 
     
    private class ChoiceOnClickListener implements DialogInterface.OnClickListener { 
 
        private int which = 0; 
        @Override 
        public void onClick(DialogInterface dialogInterface, int which) { 
            this.which = which; 
        } 
         
        public int getWhich() { 
            return which; 
        } 
    } 
}
