android - 在 GridView 中仅更改一项的大小

Question

public void onBindViewHolder(final ViewHolder viewHolder, final int position) {
    viewHolder.button.setText("button" + +position);    
    if(position == 0){
        RecyclerView.LayoutParams params = (RecyclerView.LayoutParams);
        viewHolder.button.getLayoutParams();
        params.height = 200;
        params.width = 200;
        viewHolder.itemView.setLayoutParams(params);
    }else{
        RecyclerView.LayoutParams params = (RecyclerView.LayoutParams);
        viewHolder.button.getLayoutParams();
        params.height = RecyclerView.LayoutParams.WRAP_CONTENT;
        params.width = RecyclerView.LayoutParams.WRAP_CONTENT;
        viewHolder.itemView.setLayoutParams(params);
    }
}

GridView在我试图为 的第一项提供自定义大小的适配器中使用此代码GridView，但它会更改行中所有项的大小，但其他列的项保持正常。那么我怎样才能只更改 1 个项目GridView呢？

Answer 1

if(position == 0){
    RecyclerView.LayoutParams params = (RecyclerView.LayoutParams);
    viewHolder.button.getLayoutParams();
    params.height = 200;
    params.width = 200;
    viewHolder.itemView.setLayoutParams(params);
}else{
   //make other item normal
}
