Drawable drawable = context.getResources().getDrawable(
R.drawable.radiobg);
drawable.setBounds(0, 0,
drawable.getIntrinsicWidth(),
drawable.getIntrinsicHeight());
RadioButton radioButton=new RadioButton(context);
radioButton.setButtonDrawable(android.R.color.transparent);
radioButton.setTextSize(16);
radioButton.setTextColor(Color.parseColor("#393939"));
radioButton.setCompoundDrawables(null,null,drawable,null);
radioButton.setText(deliverytime.getName());
这样就可以写成自己需要的样式
