我正在制作一个程序，其中我在弹出窗口中有一个微调器，但结果是当我单击微调器时出现错误并退出应用程序，并且不明白，我很绝望，我需要你的帮助，非常感谢您提前=）

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 <CharSequence> (context, 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);


}

在 logcat 中什么也没告诉我，我只直接跳到调试，它告诉我：

Thread [<1> main] (Suspended (exception WindowManager$BadTokenException))   
    <VM does not provide monitor information>   
    WindowManagerGlobal.addView(View, ViewGroup$LayoutParams, Display, Window) line: 255

您似乎忘记将视图设置为内容。

View layout = layoutInflater.inflate(R.layout.popup_elegir_registros, viewGroup);
this.setContentView(layout);
