弹出窗口中的自动完成文本视图 [英] Autocomplete TextView in PopupWindow

问题描述

我正在像这样点击按钮时显示 PopupWindow.

I am showing PopupWindow on button click like this.

public void Search_Click(View view) {
    try 
    {
      Display display=getWindowManager().getDefaultDisplay();
      LayoutInflater inflater = (LayoutInflater) IssueTokenActivity.this
                                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
      View layout = inflater.inflate(R.layout.activity_pop_up_transporter_details,
                        (ViewGroup) findViewById(R.id.popup_element));
      AutoCompleteTextView act=(AutoCompleteTextView)layout.findViewById(R.id.act_trans_name);
        ArrayAdapter<String> dataadapter=new ArrayAdapter<String>(view.getContext(), android.R.layout.simple_dropdown_item_1line,list);
        dataadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        act.setAdapter(dataadapter);
        act.setThreshold(1);

        //TODO: Need to support for higher API
        pwindo = new PopupWindow(layout,display.getWidth()-60, display.getHeight()-400, true);
        pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);

        btnClosePopup = (Button) layout.findViewById(R.id.btn_close_popup);
        btnClosePopup.setOnClickListener(cancel_button_click_listener);

    } 
    catch (Exception e) 
    {
        e.printStackTrace();
    }
}

但是我在输入 AutoCompleted TextView 时遇到这个错误.

But I am getting this error while typing in AutoCompleted TextView.

推荐答案

最好使用 dialog(android.app.Dialog) 来实现 AutoCompleteTextView.我认为在 PopupWindow 中添加 AutoCompleteTextView 是不可能的(你会得到异常).您可以在弹出窗口中添加微调器.如果使用对话框而不是弹出窗口，您可以实现两者.

Better to use dialog(android.app.Dialog) to implement AutoCompleteTextView.In my opinion its not possible to add AutoCompleteTextView in PopupWindow(you will get Exception).You can add Spinner in Popupwindow.You can implement both if are using dialog instead of popup.
