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

答案 0 :(得分：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;
}
答案 1 :(得分：0)
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());
答案 2 :(得分：0)
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);
}
});
