Android Spinner improper rendering if generated programmatically in android 2.0

This code is written in layout/xml file for spinner:

<Spinner
  android:id="@+id/planets_spinner"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:entries="@array/planets_array" />

Java code inside onCreate(Bundle savedInstanceState){} in MainActivity.java:

ArrayList<String> spinnerArray = new ArrayList<String>();
    spinnerArray.add("one");
    spinnerArray.add("Jupiter");
    spinnerArray.add("Mercury");
    spinnerArray.add("Venus");
    spinnerArray.add("Earth");

Spinner spinner = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, spinnerArray);

spinner.setAdapter(spinnerArrayAdapter);

enter image description here What could be going wrong?

You are using the wrong resource... the checkable style you use is meant for the dropdown resource only...

following should work (note simple_spinner_dropdown_item != simple_spinner_item):

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