ListView onClickListener() does not work after adding RadioButton(添加 RadioButton 后 ListView onClickListener() 不起作用)
问题描述
我有一个 ListView
(my_list.xml):
<ListView
android:id="@+id/my_list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:choiceMode="singleChoice"
/>
每个列表项的布局是(list_item.xml):
The layout for each list item is (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 代码中,我使用 SimpleAdapter
作为列表:
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+"");
}
});
如您所见,在上面的代码中,在列表项布局中,我添加了一个 RadioButton
,添加此按钮后,我的列表 onClickListener
不再起作用,为什么??(如果列表项布局上没有 RadioButton
则有效)
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
为您的 RadioButton 设置以下属性:
Set the following properties to your RadioButton:
android:focusable="false"
android:focusableInTouchMode="false"
在您的 OnItemClickListener 中,您需要通过代码设置单选按钮的 checked 标志.
and in your OnItemClickListener, you need to set the radio button's checked flag by code.
如下设置你的 ListView:
Set you ListView as below:
<ListView
android:id="@+id/my_list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
