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>
