这是XML:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
style="@style/LightStyle"
android:layout_width="fill_parent"
android:layout_height="55dip"
android:clickable="true"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" />
</RelativeLayout>
如何以编程方式设置样式属性?
