Question

我的应用程序如果poulsas按钮弹出一个有两个微调器的弹出窗口，那么我就可以在那里弹出窗口了但是当我得到错误时就是当我点击微调器时。

在这里你有我的下面代码和调试，因为logcat我把一切都搞定了。

 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);




    }

调试我的第二个错误：

我做了调试，错误必须在这里：

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);

Answer 1

在微调器中添加 android：spinnerMode =＆＃34;对话框＆＃34; 解决了我的问题。

Answer 2

我解决了同样的问题。在xml类中添加你的微调器。

android:spinnerMode="dialog"

Answer 3

试试这个，

//声明你的arraylist拳头并添加一些项目

  private ArrayList<String> item = new ArrayList<String>();
  item.add("1");
  item.add("2");

//像这样更改你的数组适配器

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

Answer 4

用这个替换相应的行，看看会发生什么：

final View layout = layoutInflater.inflate(R.layout.popup_elegir_registros, new ViewGroup(this) {

    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b) {
        // TODO Auto-generated method stub

    }
});

    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);

    new Handler().postDelayed(new Runnable(){

        public void run() {
            popup.showAtLocation(layout, Gravity.NO_GRAVITY, 200, 200);
        }

    }, 100L);

    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);

和this将有助于创建弹出窗口，this也可以

Answer 5

如果要在弹出窗口中设置微调器，请执行以下操作：

//this your inside layout
final LayoutInflater layoutInflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//and that is your spinner
ArrayAdapter<String> adapterState =
                new ArrayAdapter<String>(
                        layoutInflater.getContext(),
                        android.R.layout.simple_spinner_item,
                        keysState);

        adapterState.setDropDownViewResource(
                android.R.layout.simple_spinner_dropdown_item);
        spinnerState.setAdapter(adapterState);

使用layout.getContext（）而不是getApplicationContext（）或Activty.this等因为你在另一个布局视图中。
