Question

我正在创建一个程序，其中我在弹出窗口中有一个微调器但是当我点击微调器时我发现错误并退出应用程序，并且不明白，请我绝望，我需要你的帮助，非常感谢你提前=）

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);


}

您似乎忘了将视图设置为内容。

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