Radiobutton添加內容有三種方式：
1.?Drawable?drawable=?getResources().getDrawable(R.drawable.btn_home);
int?w?=?drawable.getIntrinsicWidth();
int?h=drawable.getIntrinsicHeight();
/////這一步必須要做,否則不會顯示.
drawable.setBounds(0,?0,?w,?h);
rb.setCompoundDrawables(null,drawable,null,null);
rb.setPadding(0,20,?0,?0);
2.?rb.setCompoundDrawablesWithIntrinsicBounds(null,drawable,null,null);
3.?rb.setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.btn_home,0,0);
