I am setting up a RadioGroup with RadioButtons, and they are all populated dynamically based on data in Firebase. I set the parameters as follows:

 mParams = new RadioGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

    mParams.setMargins(0,0,4,6);

I then instantiate my RadioButton objects:

public void addRadioButtonsWithFirebaseAnswers(List<DocumentSnapshot> answers) {

        mPollAnswerArrayList = new ArrayList<RadioButton>();

        int indexCreated = 0;

        for (DocumentSnapshot answerSnapshot : answers) {

            Answer answer = answerSnapshot.toObject(Answer.class);

            mPollAnswerArrayList.add((indexCreated), new RadioButton(mContext));

            RadioButton radioButton = mPollAnswerArrayList.get(indexCreated);

            radioButton.setTag(indexCreated);

            radioButton.setText(answer.getAnswer().toString());

            radioButton.setTextColor(getResources().getColor(R.color.black));

            radioButton.setButtonDrawable(R.drawable.custom_btn_radio);

            //TODO: Investigate if this line is necessary

            radioButton.setTextSize(TypedValue.COMPLEX_UNIT_PX, getResources().getDimension(R.dimen.radio_button_answer_text_size));



            mPollQuestionRadioGroup.addView(radioButton, mParams);

            indexCreated++;

        }

    }

Below is how it is appearing. I want to add space between the radio button and the text. I also want space between each button. Finally, I would like the text centered with the button if possible.

this is an easy for how you can add a space between the button and text:

radioButton.setText("   " + answer.getAnswer().toString());

To change the distance between buttons, you can do:

LayoutParams params = new LayoutParams(

    LayoutParams.WRAP_CONTENT,      

    LayoutParams.WRAP_CONTENT

);

params.setMargins(leftMargin, topMargin, rightMargin, 15);

radioButton.setLayoutParams(params);

The 15 is the bottomMargin which you can change as you wish. I hope this helps.

Try this.

LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,

                    ViewGroup.LayoutParams.WRAP_CONTENT);

    layoutParams.setMargins(10, 10, 10, 10); // leftMargin, topMargin, rightMargin, buttomMargin

     RadioGroup radioGroup = new RadioGroup(getContext());

     RadioButton radioButton = new RadioButton(getContext());

     radioButton.setLayoutParams(params1);

     radioButton.setId(1);

     radioButton.setText("text");

     radioButton.setPadding(0, 5, 0, 5); // leftMargin, topMargin, rightMargin, buttomMargin

     radioGroup.addView(radioButton);

use this for check/select the radio button,

radioGroup.check(3);  

use this for unchecked the radio button,

radioGroup.clearCheck();
