问题
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.
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);
}

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);

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

回答2:
I solved this same problem.Add your spinner in xml class.
android:spinnerMode="dialog"
回答3:
try this,
//Declaer your array list fist and add some itms
private ArrayList<String> item = new ArrayList<String>();
item.add("1");
item.add("2");
// Change your array adapter like this
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);
回答4:
replace the appropriate lines with this and see what happens:
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);
and this will help in creating a popupwindow and this also
回答5:
If you want to set spinner inside popup window then do the following:
//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);
Use layout.getContext() instead of getApplicationContext() or Activty.this etc because your are inside the another layout view.
