java - Android RadioButtons 看起来太亮

Question

我创建了一个投票应用程序，并注意到我的 RadioButton 非常轻，我几乎看不到与 RadioButton 关联的圆圈。如果可能的话，我想将 RadioButtons 变暗或加粗(以编程方式)。

我以编程方式添加我的单选按钮:

public void addRadioButtonsWithFirebaseAnswers(DataSnapshot dataSnapshot, int numberOfAnswers) {
    mPollAnswerArrayList = new ArrayList<RadioButton>();
    for (int i = 0; i < numberOfAnswers; i++) {
        Log.e("Number of Answers", "The number of answers is " + numberOfAnswers);
        mPollAnswerArrayList.add(i, new RadioButton(getActivity().getApplicationContext()));
        mPollAnswerArrayList.get(i).setId(i);
        String firebaseChild = String.valueOf(i + 1);
        mPollAnswerArrayList.get(i).setText(dataSnapshot.child(POLL_ANSWERS_LABEL).child(firebaseChild).child("Answer").getValue().toString());
        mPollAnswerArrayList.get(i).setTextColor(getResources().getColor(R.color.black));
        mPollAnswerArrayList.get(i).setTextSize(TypedValue.COMPLEX_UNIT_PX, getResources().getDimension(R.dimen.radio_button_answer_text_size));
        mParams.setMargins((int) getResources().getDimension(R.dimen.radio_question_margin_left), 0, 0, (int) getResources().getDimension(R.dimen.radio_question_margin_bottom));

        mPollQuestionRadioGroup.addView(mPollAnswerArrayList.get(i), mParams);
    }
}

您必须使用自定义单选按钮或考虑更改 Activity 的背景。
