问题描述

我正在以编程方式将问题的多个答案添加为 RadioGroup 中的 RadioButtons(参见下面的代码和图片).

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

我几乎实现了它，但我不想有一个带有文本的单选按钮(见下图)，我希望只有文本和背景.

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.

我可以去掉单选按钮吗?

Can I get rid of the radio button?

或者我可以将我当前的背景设置为单选按钮(带有选中/未选中状态)，并添加一个与其重叠的文本吗?

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();
}

推荐答案

好的，我用了

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

移除按钮，并使用选择器作为 btn_ans:

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>
