recycleview中获取用户当前点击位置
在Adapter中设置cardView的点击事件
需要定位用户点击的位置
问题：holder.getAdapterPosition()一直返回-1,而不是返回点击的位置
解决：使用tag解决
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (mContext==null){
mContext=parent.getContext();
}
View view= LayoutInflater.from(mContext).inflate(R.layout.essay_item,parent,false);
//点击显示的资源后进入详细页面
final ViewHolder holder = new ViewHolder(view);
holder.cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//获取当前点击
//int position = holder.getAdapterPosition();
// getState((Integer) v.getTag());
//取出position
int position = (Integer) v.getTag();
/*if(position == -1)+1
return;*/
EssayItem fruit = mEssayItem.get(position);
Intent intent = new Intent(mContext, CurrentItemActivity.class);
intent.putExtra(CurrentItemActivity.FRUIT_NAME, fruit.getEssayTitle());
intent.putExtra(CurrentItemActivity.FRUIT_IMAGE_ID, fruit.getImageId());
LogUtil.d(TAG,fruit.toString());
mContext.startActivity(intent);
}
});
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(ListAdapter.ViewHolder holder, int position) {
EssayItem essay=mEssayItem.get(position);
holder.essayName.setText(essay.getEssayTitle());
Glide.with(mContext).load(essay.getImageId()).into(holder.essayImage);
//记录当前position
holder.itemView.setTag(position);
}
