Question

我在每个listView项目中都有一个TextView。我已经设置了每个TextView的值。但我无法获得TextView的价值。每次我点击任何TextView，它都会获取ListView项的最后一个TextView的值。

   @Override
 public View getView(int position, View convertView, ViewGroup parent) {
 if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.offer_list_item,parent, false);
holder.tv1 = (TextView) convertView.findViewById(R.id.offer_name);
holder.tv2 = (TextView) convertView.findViewById(R.id.expiry_date);
holder.tvoid = (TextView) convertView.findViewById(R.id.offer_id);
convertView.setTag(holder);
} 
else 
{
holder = (ViewHolder) convertView.getTag();
}
OfferItem it = item.get(position);
holder.tv1.setText(it.getoffer_name());
final String message = holder.tv1.getText().toString();
holder.tv2.setText("Offer ends: " + it.getexpiry_date());
holder.tvoid.setText(it.getoffer_id());
String offerid = holder.tvoid.getText().toString();
System.out.println(offerid);
return convertView;
    }

如何获取offer_id的价值..

String offerid = holder.tvoid.getText().toString();

Answer 1

将值TextView作为标记放置，然后点击已点击查看的点击标记值。

holder.tvoid.setTag(it.getoffer_id());

holder.tvoid.setOnClickListener(new OnClickListener() {
    public void onClick(View arg0) {
        int id = (int) arg0.getTag();
    }
});

Answer 2

试试这个..

   holder.tvoid.setOnClickListener(new OnClickListener(){
        @SuppressLint("NewApi")
        public void onClick(View arg0) {

            String offerid = holder.tvoid.getText().toString();
            System.out.println(offerid);

        }
    });

或在listview中单击ClickListener

    listview.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View v, int position,
                long id) {
            String val = ((TextView) v.findViewById(R.id.offer_id)).getText().toString().trim();
            Log.v("ListSelected Item", "" + val);
            System.out.println(val);
        }
    });

Answer 3

要获取每个单击的TextView项的值，请使用ListView项单击侦听器中的以下代码： -

@Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position,
                long arg3) {


            String str = ((TextView)view.findViewById(R.id.txtViewName)).getText().toString();

            Toast.makeText(getActivity(), "" + str, 0).show();

        }
    };

Answer 4

您可以在ListView的onItemClick侦听器中执行此操作。

@Override
    public void onItemClick(AdapterView<?> adapterView, View view,
            int position, long id) {
        if (view != null) {
            EditText editText = (EditText) view.findViewById(R.id.edittext1);
            if (editText!= null) {
                String text = citiesView.getText().toString();
            }
        }

Answer 5

单击ListView的项目时，会触发onItemClick。您可以通过AdapterView.getItemAtPosition

检索您点击的项目的内容

Override
public void onItemClick(AdapterView<?> adapterView, View view,
        int position, long id) {

 OfferItem it = (OfferItem)adapterView.getItemAtPosition(position);
}
