listview位置值不超过5

时间：2017-07-17 09:21:01

标签： android listview position listitem getview

我使用自定义适配器来填充使用数据正确填充的列表视图。我有一些textview从数据库中获取数据。当我点击更新时，它应该从textview获取数据并将其呈现给edittext以进行更正或更新。但它无法正常工作。点击更新一段时间启用更多两行进行更新，并从原始数据更改数据。

请帮助纠正此问题

修改您的代码，onClickListener应该在if else阻止

之外 
public class PathiAdapter extends BaseAdapter {

Context context;
List<Pathi> pathiList;

public PathiAdapter(Context context, List<Pathi> pathiList) {
    this.context = context;
    this.pathiList = pathiList;
}

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

@Override
public Pathi getItem(int position) {
    return pathiList.get(position);
}

@Override
public long getItemId(int position) {
    return pathiList.indexOf(getItem(position));
}

private class ViewHolder{
    LinearLayout l_edit;
    TextView t_pathiID;
    TextView t_pathiName;
    TextView t_centerID;
    TextView t_pointID;
    TextView t_contactNo;
    ImageButton b_edit;
    ImageButton b_delete;
    LinearLayout l_update;
    TextView e_pathiID;
    EditText e_pathiName;
    Spinner e_centerID;
    Spinner e_pointID;
    EditText e_contactNo;
    ImageButton b_update;
}

UpdatePathiActivity.PathiAdapter.ViewHolder d_holder = null;

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    if(convertView == null){
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.custom_pathi_item, null);

只需在getView

中修改此代码即可 
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    if(convertView == null){
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.custom_pathi_item, null);
        d_holder = new UpdatePathiActivity.PathiAdapter.ViewHolder();
        d_holder.t_pathiID = (TextView) convertView.findViewById(R.id.txtPathiID);
        d_holder.t_pathiName = (TextView) convertView.findViewById(R.id.txtPathiName);
        d_holder.t_contactNo = (TextView) convertView.findViewById(R.id.txtContactNo);
        d_holder.t_centerID = (TextView) convertView.findViewById(R.id.txtCenterID);
        d_holder.t_pointID = (TextView) convertView.findViewById(R.id.txtPointID);
        d_holder.b_edit = (ImageButton) convertView.findViewById(R.id.btnEdit);
        d_holder.b_delete = (ImageButton) convertView.findViewById(R.id.btnDelete);
        d_holder.l_edit = (LinearLayout) convertView.findViewById(R.id.layoutEdit);
        d_holder.l_update = (LinearLayout) convertView.findViewById(R.id.layoutUpdate);
        d_holder.e_pathiID = (TextView) convertView.findViewById(R.id.etPathiID);
        d_holder.e_pathiName = (EditText) convertView.findViewById(R.id.etPathiName);
        d_holder.e_contactNo = (EditText) convertView.findViewById(R.id.etContactNo);
        d_holder.e_centerID = (Spinner) convertView.findViewById(R.id.etCenterID);
        d_holder.e_pointID = (Spinner) convertView.findViewById(R.id.etPointID);
        d_holder.b_update = (ImageButton) convertView.findViewById(R.id.btnUpdate);          

        convertView.setTag(d_holder);
    }
    else{
        d_holder = (UpdatePathiActivity.PathiAdapter.ViewHolder) convertView.getTag();

    }

    d_holder.b_edit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Toast.makeText(context, "Clicked at :" +position, Toast.LENGTH_SHORT).show();

            }
        });   

    return convertView;
}

将Listview's onClickListener置于if和else

之外 
     if()
      {

      }
     else
      {

      }

   d_holder.b_edit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Toast.makeText(context, "Clicked at :" +position, Toast.LENGTH_SHORT).show();

            }
        });
