RadioGroup动态添加RadioButton

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

        for (int i = 0; i < 10; i++) {
            RadioButton radioButton = new RadioButton(this);
            RadioGroup.LayoutParams lp = new RadioGroup.LayoutParams(RadioGroup.LayoutParams.WRAP_CONTENT, RadioGroup.LayoutParams.WRAP_CONTENT);
            //设置RadioButton边距 (int left, int top, int right, int bottom)
            lp.setMargins(SizeUtils.dp2px(10), SizeUtils.dp2px(10), SizeUtils.dp2px(10), SizeUtils.dp2px(10));
            //设置RadioButton背景
            radioButton.setBackgroundResource(R.drawable.radiobutton_background);
radioButton.setTextColor(getResources().getColorStateList(R.drawable.radiobutton_textcolor));
            radioButton.setButtonDrawable(null);
            //设置文字距离四周的距离
            radioButton.setPadding(SizeUtils.dp2px(25), SizeUtils.dp2px(15), SizeUtils.dp2px(25), SizeUtils.dp2px(15));
            radioButton.setTextSize(SizeUtils.sp2px(28));
            radioButton.setId(i);
            radioButton.setChecked(i == 0);
            //设置文字
            radioButton.setText(i + " #罐");
