为什么在列表项单击android 2.3.3时更改ListView背景

Question

我在android 2.3.3上有一个ListView背景问题（android 4没问题）。单击列表项时，将ListView背景从@color/holo_green属性更改为android:listSelector。如何解决这个问题？

my_list.xml

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:drawSelectorOnTop="false"
    android:alwaysDrawnWithCache="false"
    android:cacheColorHint="@android:color/transparent"
    android:listSelector="@drawable/sa_list_item_selector"
    android:divider="@drawable/sa_list_divider"/>

添加android:background="@android:color/transparent"无变化

sa_list_item_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/holo_green" />
    <item android:drawable="@android:color/transparent" />
</selector>

Answer 1

也许尝试改变：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/holo_green" />
    <item android:drawable="@android:color/transparent" />
</selector>

要：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@android:color/transparent" />
    <item android:drawable="@color/holo_green" />
</selector>

看看你的选择器。代码在那里。
