Question

在ListView行项目中，其中有两个TextView，即textview（名称）和textview（移动号码），当我单击textView（移动号码）时，相同的值会一次又一次地出现，但在列表视图中每个列表都给出正确的移动号码

Answer 1

您错过了代码中的一些重要内容。

@Override
public View getViews(int position, View convertView, ViewGroup parent, ArrayList<?> arrayList) {
    Viewholder viewHolder ;
    customerDetails = (com.venue.entities.CustomerDetails) arrayList.get(position);

    if (convertView == null) {
        viewHolder = new Viewholder();//initilize viewholder here
        LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.customer_details_item_layout, parent, false);
        //your code
        viewHolder.imageButtonCall.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int pos= (int) v.getTag();//getting clicked item position
                Intent callIntent = new Intent(Intent.ACTION_CALL);
                String mobileNumber=arrayList.get(pos).getMobileNumber();//get the mobile number from clicked position 
                callIntent.setData(Uri.parse("tel:" + mobileNumber));
                startActivity(callIntent);
            }
        });
        convertView.setTag(viewHolder);//set viewholder to converview
    } else {
        viewHolder = (Viewholder) convertView.getTag(); //getting the viewholder
    }

    //your code
    if (customerDetails.getMobileNumber().equals("")) {
       //no change
    } else {
        viewHolder.customerMobileTextView.setText(customerDetails.getMobileNumber());
        viewHolder.imageButtonCall.setTag(position);//set position so that whenever image clicks you get the exact clicked position.
    }
    //your code
    return convertView;
}

Answer 2

此行更改。您需要获取每个项目的position。

使用customerDetails.get(position).getMobileNumber()。

viewHolder.customerMobileTextView.setText(customerDetails.get(position).getMobileNumber());

Answer 3

仅更改此行：

String srt = ((com.venue.entities.CustomerDetails)arrayList.get(position)).getMobileNumber();

你可以从arrayList获得这样的位置：

//Direct Call
        viewHolder.imageButtonCall.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v)
            {
                //TODO here when click same no. is showing...

String srt = ((com.venue.entities.CustomerDetails)arrayList.get(position)).getMobileNumber();
Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:" + srt));
                startActivity(callIntent);
            }
        });
