RadioButton is not showing
Question
I tried to implement a RadioGroup item to my XML layout. The code compiled just fine, however, in the App the RadioGroup (last quarter of the XML-file) is not showing. I read that a reason could be the orientation of the Linearlayout, but in my case, that looks right for me. As you can see in my code I already implemented some CardViews (they all work perfectly) what leads me to the idea that something with the RadioGroup itself is wrong. I will also post parts of my Java code because it's also likely to affect the size of the RadioGroup. Thanks for your help.

The second one <LinearLayout android:layout_width="match_parent" /> is non-sense.
Better set android:layout_width="0dp" together with android:layout_weight="1.00"
... in order not to have the trailing one node pushed outside of the screen boundaries.

I think you should put the RadioButtons in RadioGroup tag, for example:
<RadioGroup
android:id="@+id/myRadioGroup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checkedButton="@+id/btn1" >
<RadioButton
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="btn1" />
<RadioButton
android:id="@+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="btn2" />
<RadioButton
android:id="@+id/btn3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="btn3" />
</RadioGroup>
