如果我的应用程序是一个按钮，一个有两个微调器的弹出窗口，那么我可以在那里弹出弹出窗口，但是当我点击微调器时出现错误。

这里有我的以下代码和调试，因为 logcat 我一切正常。

 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:

        Thread [<1> main] (Suspended (exception WindowManager$BadTokenException))

        Thread [<14> AsyncTask #4] (Running)    
        Thread [<15> AsyncTask #5] (Running)

我做了debug，错误一定是在这里:

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);

最佳答案

在微调器中添加 android:spinnerMode="dialog" 解决了我的问题。
