使用XML将圆角添加到TextView的StateSelected Background(Add Rounded corners to StateSelected Background of TextView using XML)

 我有RecyclerView ，它包含一些TextView 。 我已将RecyclerView背景设置为以下recycler_view_background.xml 。 
 
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#000000" />
    <corners android:topLeftRadius="@dimen/player_category_radius" android:topRightRadius="@dimen/player_category_radius"
        android:bottomLeftRadius="@dimen/player_category_radius" android:bottomRightRadius="@dimen/player_category_radius"/>
    <stroke android:color="#D3D3D3" android:width="1dp" />
</shape>
 
 它工作正常，我在RecyclerView上得到了圆角。 
 
 这是一个问题，当我尝试将背景选择器添加到任何一个TextViews它们都没有显示圆角。 这是每个项目category_item_selector.xml的背景xml 。 
 
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:drawable="@drawable/controlbar_gradient">
        <shape>
            <corners android:topLeftRadius="@dimen/player_category_radius" android:topRightRadius="@dimen/player_category_radius"
                android:bottomLeftRadius="@dimen/player_category_radius" android:bottomRightRadius="@dimen/player_category_radius"/>
            <stroke android:color="#D3D3D3" android:width="1dp" />
        </shape>
    </item>
</selector>
 
 我在我的RecyclerView.Adapter.ViewHolder的OnClickListener以编程方式将TextView的选择设置为true（选择器工作正常，否则我不会将所选项目带红色背景）。 
 
 以下是该应用程序的片段。 
 
   
 
 RecyclerView有圆角，但TextView的背景正在绘制它。 因此，当所选View位于顶部或底部时。 
 
 圆角不再可见，即使在我在所选视图上添加圆角时也不应该看到。 
 
 我一直在寻找类似的解决方案。 根据这个 ，我的是正确的。 

I have RecyclerView which holds some TextViews. I have set background of the RecyclerView to the following recycler_view_background.xml.
 
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#000000" />
    <corners android:topLeftRadius="@dimen/player_category_radius" android:topRightRadius="@dimen/player_category_radius"
        android:bottomLeftRadius="@dimen/player_category_radius" android:bottomRightRadius="@dimen/player_category_radius"/>
    <stroke android:color="#D3D3D3" android:width="1dp" />
</shape>
 
And it works fine, I get rounded corners on my RecyclerView.
 
Here's the catch, when I try to add a background selector to any one of the TextViews they don't show rounded corners. Here's the background xml for each item category_item_selector.xml.
 
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:drawable="@drawable/controlbar_gradient">
        <shape>
            <corners android:topLeftRadius="@dimen/player_category_radius" android:topRightRadius="@dimen/player_category_radius"
                android:bottomLeftRadius="@dimen/player_category_radius" android:bottomRightRadius="@dimen/player_category_radius"/>
            <stroke android:color="#D3D3D3" android:width="1dp" />
        </shape>
    </item>
</selector>
 
I am programmatically setting TextView's selected to true in my RecyclerView.Adapter.ViewHolder's OnClickListener (Selector is working fine or else I wouldn't have reddish background to the selected item).
 
Here are the snippets from the application.
 
 
 
RecyclerView has rounded corners but TextView's background is drawing over it. So when the selected View is on Top or Bottom.
 
Rounded corners are no longer visible even though it shouldn't when I have added rounded corners on selected views.
 
I keep getting similar solutions when searching for this. And mine is correct according to this.
