    @Override
    public void onClick(View v) {
        View view = getLayoutInflater().inflate(R.layout.sub_activity_menu_item_addcart, null);
        Spinner s = (Spinner)view.findViewById(R.id.sub_activity_mene_item_addcart_quantity);

        String[] items = new String[]{
            "1",  "2",  "3",  "4",  "5", 
            "6",  "7",  "8",  "9",  "10",

You cand create an alertdialog with a spinner inside, just like :

final View update_layout = getLayoutInflater().inflate(
        R.layout.update_layout, null);
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Your title");


builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {

    }
});

Spinner spinner = (Spinner) update_layout.findViewById(R.id.sub_activity_mene_item_addcart_quantity);
String[] items = { "1",  "2",  "3",  "4",  "5", 
        "6",  "7",  "8",  "9",  "10", 
        "11", "12", "13", "14", "15", 
        "16", "17", "18", "19", "20" };

ArrayAdapter<String> adapter = new ArrayAdapter<String>(HomeScreen.this,
        android.R.layout.simple_spinner_dropdown_item, items);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

builder.setView(update_layout);

AlertDialog alert = builder.create();
alert.show();

Another way to populate a Spinner is to directly specified the String array from xml. use the entries attribute in your Spinner layout file

Your spinner 

<Spinner
    android:layout_width="wrap_content"
    android:layout_height="@dimen/spinner_height"
    android:id="@+id/yourid"
    android:spinnerMode="dropdown"
    android:entries="@array/context_view"/>

Your data stored in strings.xml for example

<string-array name="context_view">
    <item>ScrollView</item>
    <item>WebView</item>
</string-array>

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,items);
spinner.setAdapter(adapter);
