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>
