RadioButton去掉默认样式小圆点

    android:id="@+id/british_stock"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:button="@null"  将button 设置为@null 即可,方便快捷!
    android:gravity="center"
    android:paddingLeft="10dp"
    android:paddingRight="10dp"
    android:textColor="@color/c_theme_title_text"
    android:textSize="15sp"
    android:text="英股"
    /> 
    
  //还有一种就是用代码这样创建RedioButton ,这样出来也不会有小圆点
 
  
  RadioButton rb = (RadioButton) LayoutInflater.from(getActivity()).inflate(R.layout.nav_radiogroup_item, null); 
  rb.setId(i);
  rb.setText(listData.get(i));
  rb.setTextSize(17);
  ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(indicatorWidth, ViewGroup.LayoutParams.MATCH_PARENT);
  rb.setLayoutParams(params);
  rg_nav_content.addView(rb);
