1,首先设置ListView的selector,定义该selector.
2,在选中ListView 的item项时高亮该item.
具体实现方法(以设置应用的heard为例):
1,设置selector,
getListView().setSelector(R.drawable.
header_list_selector
);.定义selector:
|
<?
xml
version
=
"1.0"
encoding
=
"utf-8"
?>
<
selector
xmlns:android
=
"http://schemas.android.com/apk/res/android"
>
<
item
android:state_pressed
=
"true"
android:drawable
=
"@drawable/head_list_selector_d"
/>
<
item
android:state_activated
=
"true"
android:drawable
=
"@drawable/head_list_selector_s"
/>
<
item
android:drawable
=
"@drawable/head_list_selector_n"
/>
</
selector
>
|
2,在代码中设置选中item的高亮
|
protected
void
highlightHeader(
int
id)
{
if
(id != 0)
{
Integer index =
mHeaderIndexMap
.get(id);
if
(index !=
null
)
{
getListView().setItemChecked(index,
true
);
if
(isMultiPane())
{
getListView().smoothScrollToPosition(index);
}
}
}
}
|
注意点:
1,xml文件中应该定义
android:state_activated 属性.
2,在代码中设置
getListView().setItemChecked(index,
true
);
