A fully customizible spinner for picking results with display in a TextInputLayout

Gimme that Gradle sweetness, pls?

compile 'ro.bogdanmunteanu:custompicker:0.1.9'

Maven:

<dependency>
  <groupId>ro.bogdanmunteanu</groupId>
  <artifactId>custompicker</artifactId>
  <version>0.1.9</version>
  <type>pom</type>
</dependency>

Ivy:

<dependency org='ro.bogdanmunteanu' name='custompicker' rev='0.1.9'>
  <artifact name='custompicker' ext='pom' ></artifact>
</dependency>

Latest version is 0.1.9

Does it work on my Grandpa Gary's HTC Dream?

Nope. The minSDK version is API level 11 (Honeycomb).

How do I use it?

Just put the component into your layout and start customizing it.

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ro.bogdanmunteanu.custompicker.CustomPicker
        android:id="@+id/customPicker"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        picker:resultsListHeight="200dp"
        picker:resultsViewTextColor="@color/colorPrimaryDark"
        picker:spinnerBackground="@color/colorPrimaryDark">
    </ro.bogdanmunteanu.custompicker.CustomPicker>

</RelativeLayout>

Activity example :

The activity must implement PickerViewActions
public class MainActivity extends AppCompatActivity implements PickerViewActions {

    CustomPicker<Planet> picker;
   
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        picker = (CustomPicker<Planet>) findViewById(R.id.customPicker);
        ArrayList<Planet> planets = new ArrayList<>();
        planets.add(new Planet("Earth"));
        planets.add(new Planet("Jupiter"));
        planets.add(new Planet("Mars"));
        planets.add(new Planet("Saturn"));
        planets.add(new Planet("Pluto"));
        PlanetAdapter planetAdapter = new PlanetAdapter(this.getApplicationContext(),planets);
        picker.setAdapter(planetAdapter);
        picker.setHint("Test");
    }

    @Override
    public void onPickerExpanded(CustomPicker picker) {
		//here you can put what do you want to happen on picker expanded , thinks like animations , hide other elements or so.
    }
}

Adapter example :

The adapter must implement PickerActions
public class PlanetAdapter extends ArrayAdapter<Planet> implements PickerActions {

    public PlanetAdapter(Context context, List<Planet> objects) {
        super(context, 0, objects);
    }

    @NonNull
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // Get the data item for this position
        Planet planet = getItem(position);
        // Check if an existing view is being reused, otherwise inflate the view
        if (convertView == null) {
            convertView = LayoutInflater.from(getContext()).inflate(R.layout.adapter_item, parent, false);
        }
        // Lookup view for data population
        TextView tvName = (TextView) convertView.findViewById(R.id.textView);
        // Populate the data into the template view using the data object
        tvName.setText(planet.getName());
        // Return the completed view to render on screen
        return convertView;
    }


    @Override
    public boolean isValid(int position) {
        return true;
    }

    @Override
    public int getValidPosition(int position) {
        return position;
    }

    @Override
    public String getResultforItem(int position) {
        return getItem(position).getName();
    }
}

Custom attributes

picker:resultsListHeight -  set the spinner height. The list is scrollable, so don't worry if you have more elements in the spinner. Just make it look good
picker:resultsViewTextColor - if you want to set the text colour without using the android:theme attribute. That works also, don't worry.
picker:spinnerBackground - set the background color of the spinner
