Answer 1

您必须使用在您的适配器中设置默认文本颜色的else语句：

...
if(position==0){
            holder.name.setTextColor(context.getResources().getColor(R.color.blue_color));
        } else {
          // here set your default text color black for example
          holder.name.setTextColor(context.getResources().getColor(R.color.black_color));
}
...

希望它有所帮助！

Answer 2

您的else条件？

    if(position==0)
    {
              holder.name.setTextColor(context.getResources().getColor(R.color.blue_color));
    } else {

    // Calling when if Condition not Satisfied .
             holder.name.setTextColor(context.getResources().getColor("Your_Color"));
            }
