<RadioGroup

你有一些亂七八糟的重量，layout_weight和weightSum。 這個固定的代碼應該工作：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android2="http://schemas.android.com/apk/res/android" 
    xmlns:android="http://schemas.android.com/apk/res/android"

    <LinearLayout 
     android:id="@+id/linearLayout1" 
     android:layout_width="match_parent"
