ListView的onClickListener()将单选按钮后无法正常工作 [英] ListView onClickListener() does not work after adding RadioButton
问题描述
我有一个的ListView
( my_list.xml ):
<ListView
android:id="@+id/my_list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:choiceMode="singleChoice"
/>
对于每个列表项的布局( list_item.xml ):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
>
<ImageView
android:id = "@+id/my_icon"
android:layout_width ="wrap_content"
android:layout_height ="wrap_content"
android:layout_centerVertical="true"
/>
<TextView
android:id="@+id/my_str"
android:layout_width="wrap_content"
android:layout_height = "wrap_content"
android:layout_toRightOf="@id/my_icon"
/>
<!--This radio button makes the list item unselectable, why?-->
<RadioButton
android:id="@+id/my_radio_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
在Java的code,我用 SimpleAdapter
的名单:
In Java code, I use SimpleAdapter
for the list:
my_list = (ListView) findViewById(R.id.my_list);
SimpleAdapter adapter = new SimpleAdapter(context, getOptions(),
R.layout.list_item,
new String[] { "icon1","str1" },
new int[] {R.id.my_icon, R.id.my_str });
my_list.setAdapter(adapter);
//onClickListener does not work after I added RadioButton in list item layout
my_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Log.v("SELECTED", position+"");
}
});
正如你看到的,在上述code,列表中的项目布局,我添加了一个单选
,之后我加入这个按钮,我的列表 onClickListener
不工作了,为什么? (它的工作原理,如果它没有单选
列表项的布局)
As you see, in above code, in the list item layout, I added a RadioButton
, after I added this button, my list onClickListener
does not work anymore, why?? (It works if it's without RadioButton
on list item layout)
推荐答案
设置以下属性,以您的单选按钮
Set the following properties to your RadioButton:
android:focusable="false"
android:focusableInTouchMode="false"
和你的 OnItemClickListener 的,你需要设置单选按钮的检查标志由code。
and in your OnItemClickListener, you need to set the radio button's checked flag by code.
设为您的ListView如下:
Set you ListView as below:
<ListView
android:id="@+id/my_list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
