这是我取得的成就？ 3个不同的部分,每个部分10个不同的项目.
这是我正在关注的教程link,下面是截图：
试图为每个部分显示不同的视图.喜欢：
对于第1节(layout_1.xml)
对于第2节(layout_2.xml)
对于第3节(layout_3.xml)
但是在每个Section中显示layout_1.xml的布局视图……(第1,2,3节)
public class SectionListDataAdapter extends RecyclerView.Adapter<SectionListDataAdapter.SingleItemRowHolder> {
private ArrayList<SingleItemModel> itemsList;
private Context mContext;
public SectionListDataAdapter(Context context,ArrayList<SingleItemModel> itemsList) {
this.itemsList = itemsList;
this.mContext = context;
}
@Override
public SingleItemRowHolder onCreateViewHolder(ViewGroup viewGroup,int i) {
switch (i) {
case 0:
View viewONE = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.layout_1,null,false);
SingleItemRowHolder rowONE = new SingleItemRowHolder(viewONE);
return rowONE;
case 1:
View viewTWO = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.layout_2,false);
SingleItemRowHolder rowTWO = new SingleItemRowHolder(viewTWO);
return rowTWO;
case 2:
View viewTHREE = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.layout_3,false);
SingleItemRowHolder rowTHREE = new SingleItemRowHolder(viewTHREE);
return rowTHREE;
}
return null;
}
@Override
public void onBindViewHolder(SingleItemRowHolder holder,int i) {
SingleItemModel singleItem = itemsList.get(i);
holder.tvTitle.setText(singleItem.getName());
}
@Override
public int getItemCount() {
return (null != itemsList ? itemsList.size() : 0);
}
public class SingleItemRowHolder extends RecyclerView.ViewHolder {
protected TextView tvTitle;
protected ImageView itemImage;
public SingleItemRowHolder(View view) {
super(view);
this.tvTitle = (TextView) view.findViewById(R.id.tvTitle);
this.itemImage = (ImageView) view.findViewById(R.id.itemImage);
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(v.getContext(),tvTitle.getText(),Toast.LENGTH_SHORT).show();
}
});
}
}
}
解决方法
在内部适配器的getItemViewType中使用它：
@Override
public int getItemViewType(int position) {
if (position == 0) {
return 0;
} else if(position == 1) {
return 1;
} else {
return 2;
}
}
