Question

在我的程序使用列表和适配器中。item_list.xml中有textview（cod，time，...）和图片（editicon）。现在，我想当我单击pictur时，鳕鱼textview中的内容是什么，其他textview中的内容又发送另一个活动。我该如何发送textview中的所有内容。我只是了解了使用putextra发送textvie的内容。谢谢亲爱的朋友

公共类ContactAdapter扩展了ArrayAdapter { 私人列表联系人；

public ContactAdapter(Context context, List< MyContact> contacts) {
    super(context,R.layout.item_list,contacts);


    this.contacts=contacts;



}


@NonNull
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    MyContact contact = contacts.get(position);
    ViewHolder holder;


    if(convertView == null){
        LayoutInflater inflater = (LayoutInflater)
                getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.item_list, parent, false);
        holder = new ViewHolder();

        holder.companyname = (TextView) convertView.findViewById(R.id.companyname);
        holder.cod = (TextView) convertView.findViewById(R.id.cod);
        holder.bigan = (TextView) convertView.findViewById(R.id.bign);
        holder.stop = (TextView) convertView.findViewById(R.id.stop);

        holder.time = (TextView) convertView.findViewById(R.id.time);
        holder.date = (TextView) convertView.findViewById(R.id.date);
        holder.price = (TextView) convertView.findViewById(R.id.price);
        holder.editicon = (ImageView) convertView.findViewById(R.id.imageView);

        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.fill(contact);
    return convertView;
}


private class ViewHolder implements View.OnClickListener {

    public TextView companyname;
    public TextView cod;
    public TextView bigan;
    public TextView stop;
    public TextView date;
    public TextView time;


    public TextView price;

    public ImageView editicon;

    public void fill(MyContact contact) {


        companyname.setText(contact.getCompany());

        cod.setText(contact.getCod());
        time.setText(contact.getTime());
        date.setText(contact.getDate());
        bigan.setText(contact.getBigan());
        stop.setText(contact.getStop());
        price.setText(contact.getPrice());
        editicon.setTag(contact.getCod());
       //  editicon.setTag(contact.getBigan());


           editicon.setOnClickListener(this);

    }


    @Override
    public void onClick(View v) {





            String codearash = (String) v.getTag();



        Intent intent12 = new Intent(getContext(), Cod.class);

        intent12.putExtra("keycod", codearash);

                   getContext().startActivity(intent12);



        }












    }



}

Answer 1

您似乎正在做的是在您点击的视图中寻找ListView。这将失败。

您需要在editicon类的onClick实现中激发意图。

ViewHolder

将7 textview的内容传输到适配器上的另一个活动
