如何在RecyclerView“ Android应用程序”中设置第一行的背景颜色

Question

I used RecyclerView for displaying items as rows, and all the rows having background color is white. But i want to change first row background color as silver and rest will be white. Please help me.

Answer 1

In the onBindViewHolder

if( position == 0){
   holder.view.setBackgroundColor(whatever_color);
}

In viewHolder class

View view;
public MyViewHolder(View itemView){
  view = itemView;

Answer 2

In your onBindViewHolder method of recycleView adapter class, you can use position parameter to perform required functionality. In your case, it will be position = 0

@Override
public void onBindViewHolder(ViewHolder holder, final int position) {

Answer 3

Would suggest to have a look at ViewType, based on that you can inflate the correct view.

See https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter.html#getItemViewType(int)
