Question

这是我的Adapter类

  public class GridViewCustomAdapter extends BaseAdapter {


private List<ProductParameterBO> availList;


private LayoutInflater inflater;

Context context;

public GridViewCustomAdapter(Context ctx,List<ProductParameterBO> list){
    this.context = ctx;
    this.availList = list;
}

@Override
public int getCount() {
    return availList.size();
}

@Override
public Object getItem(int position) {
    return availList.get(position);
}

@Override
public long getItemId(int position) {
    ProductParameterBO c = availList.get(position);
   // long id = c.getTimeId();
    return 0;
}

@Override
public View getView(final int position,View convertView,final ViewGroup parent) {

    View row = convertView;
  final TeeTimeHolder holder;
    if (row == null){
        inflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.grid_row,parent,false);
        holder = new TeeTimeHolder();
        holder.myImage =(ImageView)row.findViewById(R.id.imageView10);
        holder.imageflip =(ImageView)row.findViewById(R.id.img_flp);
        holder.name =(TextView)row.findViewById(R.id.textView47);
        holder.edit =(TextView)row.findViewById(R.id.textView49);
        holder.rl =(RelativeLayout)row.findViewById(R.id.grid_img_ovrly);
      //  holder.row =(RelativeLayout)row.findViewById(R.id.row);
        row.setTag(holder);
    }
    else {
        holder =(TeeTimeHolder)row.getTag();
    }

    holder.name.setText(availList.get(position).getParameterName());
    holder.myImage.setImageResource(R.drawable.toi);
    holder.rl.setVisibility(View.GONE);



    return row;
}




static class TeeTimeHolder {
    ImageView myImage,imageflip;

    TextView name,edit;

    RelativeLayout rl;
 }
}

我只想在选择行时显示Relativelayout r1，当我选择下一行时，前一行必须隐藏Relativelayout r1布局并显示在选中的行上。现在在我的情况下，当我选择下一行时，则它没有隐藏在上一行..layout仍显示在我选择的所有行上。

请帮助我解决这个问题..在高级的任何帮助将不胜感激..

Answer 1

 int priviousPosition=0;
    ArrayList<View> viewList= new ArrayList<View>();
    holder.rl.setTag(position);
    viewList.add(holder.rl);
    row.findViewById(R.id.grid_img_ovrly).setOnClickListener(new OnClickListener() {

    public void onClick(View v1) { 

    View v=viewList.get(priviousPosition);
    v.setVisibility(View.GONE);

    int postition=(Integer) v1.getTag();
    priviousPosition=postition;
    notifyDataSetChanged();

    }

    });
