I have a program which displays a checkbox , radiogroup and editText box. But the problem is that the edit Text Box does not show up. CheckedBox and radio buttons show up but not edit text box. In the main.xml file , if you place the editText box above he radiogroup , then the program crashes. Edit Text not declared properly?

Answer 1

Please Change your Radiogroup attributes to

         <RadioGroup
android:id="@+id/rg"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>

You used as fill_parent for layout_height attribute.
