Android-KeyValueSpinner

Spinner component that works with normal values but additionally lets you use keys of an arbitrary class.

The selected key is exposed via spinner.getKey(); and the selected value via spinner.getValue();.

Installation

• Include one of the JARs in your libs folder
• or
• Copy the Java package to your project's source folder
• or
• Create a new library project from this repository and reference it in your project

Usage

Layout (XML)

<im.delight.android.keyvaluespinner.KeyValueSpinner
	android:id="@+id/planets_spinner"
	android:layout_width="fill_parent"
	android:layout_height="wrap_content" />

Activity (Java)

KeyValueSpinner<CharSequence> spinner = (KeyValueSpinner<CharSequence>) findViewById(R.id.spinner);
// Create a KeyValueSpinner.Adapter using two string arrays and a default spinner layout
KeyValueSpinner.Adapter<CharSequence> adapter = KeyValueSpinner.Adapter.createFromResource(this, R.array.planets_keys, R.array.planets_values, android.R.layout.simple_spinner_item);
// Specify the layout to use when the list of choices appears
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// Apply the adapter to the spinner
spinner.setAdapter(adapter);

Creating the adapter from Java arrays

CharSequence[] keys;
CharSequence[] values;
...
KeyValueSpinner.Adapter<CharSequence> adapter = KeyValueSpinner.Adapter.createFromArrays(this, keys, values, android.R.layout.simple_spinner_item);

Using the constructor with four parameters

If you want to use the new constructor Spinner(Context context, AttributeSet attrs, int defStyle, int mode), which is available for API levels 11+ only, you have to call spinner.init(); manually. Otherwise, this is called automatically.
