我遇到以下问题:我的应用程序具有白色背景和ListView的布局。如果我需要滚动这个ListView,那么它会改变黑色的颜色!我刚刚为ListView制作了选择器,但它并不适用。我的ListView:
<ListView
android:id="@+id/listViewLastUpdates"
android:listSelector="@drawable/selector"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
我的选择器:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="@color/green" /> <!-- focused -->
<item android:state_focused="true" android:state_pressed="true" android:drawable="@color/green" /> <!-- focused and pressed-->
<item android:state_pressed="true" android:drawable="@color/green" /> <!-- pressed -->
<item android:drawable="@color/white" /> <!-- default -->
</selector>
我需要使用绿色作为高亮和白色作为背景(然后如果我滚动ListView它不会改变颜色)。请告诉我,我该如何解决?

在设置颜色时使用color selector
代替drawable selector
。
制作color folder inside res
并保存此颜色的xml选择器并使用它:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:color="@color/green" /> <!-- focused -->
<item android:state_focused="true" android:state_pressed="true" android:color="@color/green" /> <!-- focused and pressed-->
<item android:state_pressed="true" android:color="@color/green" /> <!-- pressed -->
<item android:color="@color/white" /> <!-- default -->
</selector>

试试这个并告诉我它是否有帮助:
<ListView
android:id="@+id/listViewLastUpdates"
android:listSelector="@drawable/selector"
android:background="@android:color/white"
android:cacheColorHint="@android:color/transparent"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
