Layout

<com.gbksoft.spinnerview.SpinnerView
        android:id="@+id/spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="20dp"
        android:padding="8dp"
        android:hint="Test hint"
        android:textColor="@color/colorAccent"
        android:textColorHint="@color/colorPrimary"
        app:sv_arrow_drawable="@drawable/ic_dropdown_arrow_animated"
        app:sv_arrow_tint="@android:color/holo_blue_bright"
        app:sv_dropdown_background="@drawable/bgn_dropdown"
        app:sv_dropdown_elevation="1dp"
        app:sv_dropdown_height="wrap_content"
        app:sv_dropdown_max_height="350dp"
        app:sv_dropdown_displayed_items_count="5"
        app:sv_dropdown_adapt_height_to_items_size="true"
         />

Customizing

There are some additional attributes to configure dropdown:

Attribute	Info
sv_arrow_drawable	right arrow icon that indicate dropdown status (expanded / collapsed)
sv_arrow_tint	tint color for right arrow
sv_dropdown_background	Background drawable for dropdown
sv_dropdown_elevation	Dropdown elevation
sv_dropdown_max_height	Dropdown max height (it will not expand more than this value)
sv_dropdown_displayed_items_count	Set count of displayed items in dropdown view
sv_dropdown_adapt_height_to_items_size	This flag will resize dropdown view size to match of full view height
sv_dropdown_height	match_parent, wrap_content

To make arrow rotatable define sv_arrow_drawable like this:

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/ic_dropdown_arrow"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="180" />

Usage in code

To add items into dropdown you have to set adapter to SpinnerView. Adapter must extend SpinnerAdapter.

final SpinnerView spinner = findViewById(R.id.spinner);
spinner.setAdapter(spinnerAdapter); //Adapter must extend SpinnerAdapter

spinner.setOnItemSelectedListener(new SpinnerView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(int position) {
        //Item selected
    }
});

spinner.setOnNothingSelectedListener(new SpinnerView.OnNothingSelectedListener() {

    @Override
    public void onNothingSelected() {
        //Nothing selected
    }
});
