当我单击时，弹出窗口中的错误微调框

问题描述

我的应用程序如果将一个按钮弹出一个弹出窗口，该弹出窗口具有两个微调器，那么我就可以在那里弹出该窗口，但是当我收到错误消息时，是单击微调器.

My app if poulsas a button a pop-out which has two spinners, well then I get the pop-up there all right but when I get the error is when I click on the spinner.

这里您有下面的代码并进行调试，因为logcat使我一切正常.

Here you have my below code and debug, because logcat I get everything right.

 public void añadirRegistro(View v){

         showPopup(leer_registros.this);
    }
    private void showPopup(final Activity context) {

           Spinner eleccionIP,eleccionRegistro;
           borrar_datos BorrarDatos = new borrar_datos ();
           // Inflate the popup_layout.xml
           RelativeLayout viewGroup = (RelativeLayout) context.findViewById(R.id.popup);
           LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
          View layout = layoutInflater.inflate(R.layout.popup_elegir_registros, viewGroup);


           eleccionIP = (Spinner) layout.findViewById(R.id.popupIP);
           eleccionRegistro = (Spinner)layout.findViewById(R.id.popupRegistro);



           /*Cursor cur=BorrarDatos.obtenerIP();
           BorrarDatos.rellenarSpinner(cur,eleccionIP);*/


           final PopupWindow popup = new PopupWindow(context);
           popup.setContentView(layout);
           popup.setWidth(LayoutParams.WRAP_CONTENT);
           popup.setHeight(LayoutParams.WRAP_CONTENT);
           popup.setFocusable(true);

           popup.showAtLocation(layout, Gravity.NO_GRAVITY, 200, 200);


           ArrayAdapter <CharSequence> adapter = new ArrayAdapter(this,android.R.layout.simple_spinner_item);
           adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

           adapter.add("item 1");
           adapter.add("item 2");
           eleccionIP.setAdapter(adapter);




    }

调试:

WindowManagerImpl.addView(View, ViewGroup$LayoutParams) line: 69
PopupWindow.invokePopup(WindowManager$LayoutParams) line: 993

第二个错误的调试:

Scada [Android Application]
    DalvikVM[localhost:8636]
        Thread [<1> main] (Suspended (exception WindowManager$BadTokenException))
            WindowManagerGlobal.addView(View, ViewGroup$LayoutParams, Display, Window) line: 255

        Thread [<14> AsyncTask #4] (Running)

我确实进行了调试，错误必定在这里:

I did debug, and error must be here:

RelativeLayout viewGroup = (RelativeLayout) ((Activity) context).findViewById(R.id.popup);
           LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
           View layout = layoutInflater.inflate(R.layout.popup_elegir_registros, viewGroup);


           eleccionIP = (Spinner)layout.findViewById(R.id.popupIP);
           eleccionRegistro = (Spinner)layout.findViewById(R.id.popupRegistro);

推荐答案

在Spinner中添加 android:spinnerMode ="dialog" 解决了我的问题.

Adding android:spinnerMode="dialog" in spinner solved my problem.
