无法更改android中的单选按钮圆圈颜色

Question

我在我的应用中使用radioButton，但默认情况下，我的radioButton颜色为黑色，当选择颜色为我在color.xml中提及的颜色时，但我想要将radioButton初始颜色和所选颜色更改为白色。我如何能够这样做。我尝试了背景颜色，但它改变了背景颜色属性。请帮忙。

Answer 1

首先将这个代码style.xml

<!-- custom style --> 
<style name="radionbutton" 
     parent="Base.Widget.AppCompat.CompoundButton.RadioButton"> 
    <item name="android:button">@drawable/rb_drawable</item> 
    <item name="android:windowIsTranslucent">true</item> 
    <item name="android:windowBackground">@android:color/transparent</item> 
    <item name="android:windowContentOverlay">@null</item> 
    <item name="android:windowNoTitle">true</item> 
    <item name="android:windowIsFloating">false</item> 
    <item name="android:backgroundDimEnabled">true</item> 
</style> 

现在让rb_drawable.xml在绘制文件夹

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:drawable="@drawable/radio_unchecked" android:state_checked="false" android:state_focused="true"/> 
    <item android:drawable="@drawable/radio_unchecked" android:state_checked="false" android:state_focused="false"/> 
    <item android:drawable="@drawable/radio_checked" android:state_checked="true" android:state_focused="true"/> 
    <item android:drawable="@drawable/radio_checked" android:state_checked="true" android:state_focused="false"/> 
</selector> 

现在做的单选按钮，检查2个文件/在绘制文件夹取消

radio_unchecked.xml

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="oval"> 
    <stroke android:width="1dp" android:color="@color/colorAccent"/> 
    <size android:width="30dp" android:height="30dp"/> 
</shape> 

radio_checked.xml

<?xml version="1.0" encoding="utf-8"?> 
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item> 
    <shape android:shape="oval"> 
     <stroke android:width="1dp" android:color="@color/colorAccent"/> 
     <size android:width="30dp" android:height="30dp"/> 
    </shape> 
    </item> 
    <item android:top="5dp" android:bottom="5dp" android:left="5dp" android:right="5dp"> 
    <shape android:shape="oval"> 
     <solid android:width="1dp" android:color="@color/colorAccent"/> 
     <size android:width="10dp" android:height="10dp"/> 
    </shape> 
    </item> 
</layer-list> 

最后默认

<RadioButton 
    android:layout_width="wrap_content" 
    style="@style/radionbutton" 
    android:checked="false" 
    android:layout_height="wrap_content" 
    />
