Answer 1

Declare a spinner with visibility gone in your xml

<Spinner
        android:id="@+id/spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:visibility="gone"
        android:prompt="@string/spinner_title"
    />

inside your open_spinner method :

  Spinner spinner = (Spinner) findViewById(R.id.spinner);
  spinner.setVisibility(View.VISIBLE);
  spinner.setOnItemSelectedListener(this);  

  ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, youarrayofStrings);
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

  spinner.setAdapter(dataAdapter);
