Question

我想在popup窗口中添加一个标题，该标题应该在弹出列表中修复。只有弹出列表应为scroll。我怎样才能做到这一点？请建议我。

public PopupWindow popupWindowcountry() {

    PopupWindow popupWindow = new PopupWindow(this);

    ListView listView = new ListView(this);

    listView.setAdapter(Country_Padpter);
    popupWindow.setFocusable(true);
    popupWindow.setWidth((int) (getWindowManager().getDefaultDisplay()
            .getWidth() / 2.2));

    popupWindow.setHeight(515);

    popupWindow.setContentView(listView);
    return popupWindow;
}

private class PopupWindows_Adpter extends BaseAdapter {

    @Override
    public int getCount() {
        return Country_arrayList.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @SuppressWarnings("unused")
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // View grid;
        LayoutInflater inflater = (LayoutInflater) DNPActivity.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = null;
        if (convertView == null) {
            convertView = new View(DNPActivity.this);
            convertView = inflater
                    .inflate(R.layout.country_popup_row, null);
            final TextView textView = (TextView) convertView
                    .findViewById(R.id.item_txt_popup_row);
            final LinearLayout layout = (LinearLayout) convertView
                    .findViewById(R.id.popup_ll);
            // final TextView header=(TextView)
            // convertView.findViewById(R.id.item_txt_popup_header);
            textView.setText(Country_arrayList.get(position).getName());
            textView.setBackgroundColor(Color.WHITE);
            textView.setTextColor(Color.BLACK);
            textView.setTextSize(18);
            textView.setPadding(15, 10, 10, 10);
            layout.setOnClickListener(new OnClickListener() {
                @SuppressLint("ShowToast")
                @Override
                public void onClick(View v) {
                    String selectedtext = textView.getText().toString();
                    Toast.makeText(DNPActivity.this, selectedtext,
                            Toast.LENGTH_LONG).show();
                    country_selected_txt = selectedtext;

                    tvtotalnewspapernumber.setText(country_selected_txt);
                    popupWindowcountry.dismiss();
                    new FilterAsync().execute();
                }
            });
        } else {
            convertView = (View) convertView;
        }
        return convertView;
    }

}

Answer 1

ListPopupWindow从API 11开始有几次调用。

void setPromptView(View prompt)
void setPromptPosition(int position)

这些将在列表视图的上方或下方添加自定义视图，但不能同时添加两者。列表视图滚动不会影响视图。

在弹出窗口中添加一个标题，该标题应该在弹出列表中修复

您可以通过在PopUpWindow中添加ListView for ListView来实现相同功能。这样做：

TextView tv = new TextView(this);
tv.setText("your title text here");
listView.addHeaderView(tv);

或者您也可以使用HeaderView的自定义布局，请参阅以下教程：
