How can I make a RadioButton with overlapping text?

Question

I'm adding programmatically multiple answers to a questions as RadioButtons in a RadioGroup (see code and image below).

I almost achieved it but instead of having a radio button with a text on its side (see image below), I would like to have only the text and the background.

Can I get rid of the radio button?

Or can I set my current background as the radio button (with checked/unchecked states), and add a text overlapping it?

RadioGroup answer_container = (RadioGroup) findViewById(R.id.answer_container);

while (c.isAfterLast() == false) {

    RadioButton answer = new RadioButton(PCItem.this);
    answer.setText(c.getString(c.getColumnIndex(DBAdapter.KEY_ANS_TEXT)));
    answer.setBackgroundResource(R.drawable.btn_ans);
    answer.setPadding((int)(30 * density), 0, 0, 0);
    answer.setGravity(Gravity.CENTER_VERTICAL);
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams((int)(775 * density), (int)(81 * density));
    params.setMargins(0, (int)(20*density), 0, 0);
    answer.setLayoutParams(params);

    answer_container.addView(answer);

    c.moveToNext();
}

Answer 1

Ok, I made it using

answer.setButtonDrawable(android.R.color.transparent);

to remove the button, and using a selector as btn_ans:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
<item android:state_checked="false" android:drawable="@drawable/btn_choix_unsel" /> 
<item android:state_checked="true" android:drawable="@drawable/btn_choix_sel" />
</selector>

You can use radioButton.setButtonDrawable(). You can also specify different drawables for each button state (including checked/unchecked) using a StateListDrawable.

To completely remove the button you can simply set it as null:

<RadioButton 
    android:button="@null"
    ...
/>

Be aware that by code radioButton.setButtonDrawable(null); doesn't work! The correct way is to set an empty StateListDrawable:

radioButton.setButtonDrawable(new StateListDrawable());

If you have more items, you can create a custom style to override the default properties of RadioButton:

<style name="CustomRadioButton" parent="@android:style/Widget.CompoundButton.RadioButton">
   <item name="android:button">@null</item>
   <item name="android:paddingLeft">0dp</item>
</style>

This will set the radio button. I want to remove it, or make the text overlapping it. – Repetend

I tried to set the button to null programmatically (answer.setButtonDrawable(null)), but it still shows up... – Repetend
