Center the Icon of RadioButton in RadioGroup
I am trying to center the Button of a RadioButton. None of the already answered questions here fixed my problem.
My conditions:
- the effect of a RadioGroup
- the default RadioButton Icon
- I don't want to set text to the RadioButtons
- the ButtonIcon should be centered (like the position of A1, A2, A3)
I tried different settings but nothing worked for me.
<RadioGroup
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioButton
android:layout_gravity="center"
android:gravity="center"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"/>
<RadioButton
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"/>
<RadioButton
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"/>
</RadioGroup>
EDIT: Using Placeholder-RadioButtons is not an option. In this case I would need 9 RadioButtons, but in the end this layout will be created programmatically and the amount of RadioButtons could be bigger.
Solution
Try this
