xml代码：

view plaincopy to clipboardprint?

android:id="@+id/layout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
/>
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>


android:id="@+id/layout"

}

private List> getData(){

Map map_day = new HashMap();
map_day.put("text", "白天");
map_day.put("img", R.drawable.setlist_radio_on);
list.add(map_day);

Map map_clody = new HashMap();

}

}

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(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);
}
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(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
