自定义适配器（Adapter）的使用

木头~旅人: 牛哇，大佬，我直接三连

Issac-Clarke: 受教了！谢谢！

exceptio_n: 明白了，viewholder的imageview和textview是从view获取的

exceptio_n: 我想问一下，adapter重写的getView方法返回的是view，可是并没有对view的数据的填充。数据是怎么加载到view里面的？[code=java] public class FruitAdapter extends ArrayAdapter { private int resourceId; public FruitAdapter(@NonNull Context context, int resource, @NonNull List objects) { super(context, resource, objects); resourceId=resource; } @Override public View getView(int position,View convertView, ViewGroup parent) { Fruit fruit = getItem(position); View view; ViewHolder viewHolder; if (convertView == null){ view = LayoutInflater.from(getContext()).inflate(resourceId,parent,false); viewHolder = new ViewHolder(); viewHolder.fruitImage = view.findViewById(R.id.fruit_image); viewHolder.fruitName = view.findViewById(R.id.fruit_name); view.setTag(viewHolder); }else { view = convertView; viewHolder = (ViewHolder) view.getTag(); } viewHolder [/code]

莲芸轩: 就是你布局文件的xml里面
