android 自定义 radiobutton 文字颜色随选中状态而改变

先看效果

主要是写一个 color selector

在res/建一个文件夹取名color

res/color/color_radiobutton.xml

 <?xml version="1.0" encoding="utf-8"?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android">


     <item android:state_checked="true" android:color="@color/color_text_selected"/>
     <!-- not selected -->
     <item android:color="@color/color_text_normal"/>


 </selector>

程序中就可以直接使用了

 //layout/main.xml
 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:orientation="vertical" >
     <RadioGroup
         android:id="@+id/radiogroup_personal_condition"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:orientation="horizontal" >
         <RadioButton
             android:id="@+id/radiobutton_1"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:background="@drawable/selector_radio"
             android:button="@null"
             android:checked="true"
              android:gravity="center"
              android:text="目录"
             android:textColor="@color/color_radiobutton"
             android:textSize="@dimen/font_size"
             android:textStyle="bold" />
         <RadioButton
             android:id="@+id/radiobutton_2"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:background="@drawable/selector_radio"
             android:button="@null"
              android:gravity="center"
              android:text="书签"
             android:textColor="@color/color_radiobutton"
             android:textSize="@dimen/font_size"
             android:textStyle="bold" />
     </RadioGroup>
 </LinearLayout>
