Question

我在我的应用程序中使用AutoCompleteTextView但它意外地工作。自动完成列表显示我不想要的列表中不需要的文本，但是当我选择此文本并从autocomletetextview中删除焦点时，它将正确的文本设置为autocompletetext字段。另一个问题是，当我在autocompletetextview的自定义适配器中填充列表时，我想获取autocompletetext字段中所选文本的id，我正在关联此id。这是我正在使用的代码。

autoComMarker = (AutoCompleteTextView) findViewById(R.id.auto_rainfall_of_markaz_id);
autoComMarker.setThreshold(1);
CustomMarkazAdapter adapter = new CustomMarkazAdapter(getBaseContext(),     R.layout.custom_auto_com_listview, marqazList);
autoComMarker.setAdapter(adapter);


autoComMarker.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> arg0, View view,
                int position, long arg3) {
            autoComMarker.setTag(view.getTag());
            Log.e("Markaz list", ""+view.getTag());
        }
    });

以下是CustomMarkazAdapter的代码：

public class CustomMarkazAdapter extends ArrayAdapter<Markaz>{

private ArrayList<Markaz> items;
private Context CurrentContext;
private Markaz CurrentItem;

public CustomMarkazAdapter(Context context, int textViewResourceId,
        ArrayList<Markaz> objects) {
    super(context, textViewResourceId, objects);

    items =  objects;
    CurrentContext = context;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

     if ((items == null) || ((position + 1) > items.size()))
        return convertView; //Can't extract item

   CurrentItem = (Markaz)items.get(position);    

    LayoutInflater vi = (LayoutInflater)CurrentContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    convertView = vi.inflate(R.layout.custom_auto_com_listview, null);      
    TextView text = (TextView) convertView.findViewById(R.id.custom_auto_com_text);

    text.setText(CurrentItem.getMarkazName());
    convertView.setTag(CurrentItem.getMarkazID());
    Log.e(CurrentItem.getMarkazName(),""+CurrentItem.getMarkazID());
    return convertView;
}

}

我在这里设置的markazID不是我要找的，它根据autocompletelistview项目位置设置markaz id。我不需要我需要markaz id，我用markazList传递。请帮助我，任何帮助都应该非常感激。

试试这个。

  autoComMarker.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> arg0, View view,
                    int position, long arg3) {
               Markaz items= adapter.getItem(position);
               //Now you can get items of Markaz from items.get...
            }
        });

您必须获取position中所选项目的listview。在autoComMarker.setOnItemClickListener()：

中执行以下操作

  Markaz items= adapter.getItem(position);
