Question

I am following the example in the book “Beginning Android 4” and I am getting an xml parsing error. Apparently many people have the same issue but I cannot find a posting that is similar to the books example. Below is my code. The unboudn prefix hits at the second radio group…

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"> 

    <RadioGroup android:id="@+id/orientation"
        android:orientation="horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="5dp">          
        <RadioButton
            android:id="@+id/horizontal"
            android:text="horizontal">
        </RadioButton>
        <RadioButton
            android:id="@+id/vertical"
            android:text="vertical">
        </RadioButton>
    </RadioGroup>  
    <RadioGroup android:id="@+id/gravity"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        andorid:padding="5dip">         
        <RadioButton
            android:id="@+id/left"
            andoid:test="left">
        </RadioButton>
        <RadioButton
            android:id="@+id/center"
            android:text="center">           
        </RadioButton>    
        <RadioButton
            android:id="@+id/right"
            android:text="right">
        </RadioButton>   
    </RadioGroup>        
</LinearLayout>

Answer 1

you have couple of errors in your second radiogroup

 andorid:padding="5dip"

Change this to

 android:padding="5dip"

Note the change from andorid to android and

  andoid:test="left"

to

 android:text="left"
