在CustomArrayAdapter中获取listview的当前所选项

Question

在我的customarrayadapter视图中，我有一个微调器。如果选择了微调器的其中一个项目，它将获得主Listview的当前位置。我无法获得Listview上当前项目的位置，其中微调器处于活动状态。它将只显示位置-1。

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

        Viewholder v = new Viewholder();
        v.rowView = convertView;
        v.spinner = (Spinner)v.rowView.findViewById(R.id.spinner1);

       v.spinner.setOnItemSelectedListener( new OnItemSelectedListener() {

                @Override
                public void onItemSelected(AdapterView<?> parent, View view,
                        int position, long id) {
                    // TODO Auto-generated method stub

        //Attempt code v.spinner = (Spinner)v.rowView.findViewById(R.id.spinner1);      
        Toast.makeText(getActivity(), "Position " + listview.getSelectedItemPosition(), Toast.LENGTH_LONG).show();

}

                        int arg, long id) {
                    // TODO Auto-generated method stub

        //Attempt code v.spinner = (Spinner)v.rowView.findViewById(R.id.spinner1);      
        Toast.makeText(getActivity(), "Position " + position, Toast.LENGTH_LONG).show();

    @Override
          public View getView(final int position, View convertView, final ViewGroup parent) {
            final int listview_position=position;

            Viewholder v = new Viewholder();
            v.rowView = convertView;
            v.spinner = (Spinner)v.rowView.findViewById(R.id.spinner1);

            v.spinner.setOnItemSelectedListener( new OnItemSelectedListener() {

                    @Override
                    public void onItemSelected(AdapterView<?> parent, View view,
                            int position, long id) {
                        // TODO Auto-generated method stub

                        //Attempt code v.spinner = (Spinner)v.rowView.findViewById(R.id.spinner1);      
                        Toast.makeText(getActivity(), "Position " + listview_position,Toast.LENGTH_LONG).show();
                   }
            }

    }

您的问题没有旋转，arrayadapter使用相同的名称。您也可以只更改名称

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

        Viewholder v = new Viewholder();
        v.rowView = convertView;
        v.spinner = (Spinner)v.rowView.findViewById(R.id.spinner1);

       v.spinner.setOnItemSelectedListener( new OnItemSelectedListener() {

                @Override
                public void onItemSelected(AdapterView<?> parent, View view,
                        int spinner_position, long id) {
                    // TODO Auto-generated method stub

        //Attempt code v.spinner = (Spinner)v.rowView.findViewById(R.id.spinner1);      
        Toast.makeText(getActivity(), "Position " + listview_position, Toast.LENGTH_LONG).show();

}
