Android Library : Object Spinner

Github: https://github.com/ry4nkim/ObjectSpinner

ObjectSpinner is an Android spinner library for object selection and supports searching.

Download

Download the latest AAR or grab via Gradle:

implementation 'kr.ry4nkim:objectspinner:1.0.1'

or Maven:

<dependency>
  <groupId>kr.ry4nkim</groupId>
  <artifactId>objectspinner</artifactId>
  <version>1.0.1</version>
  <type>pom</type>
</dependency>

Usage

Add the ObjectSpinner to your layout XML:

<kr.ry4nkim.objectspinner.ObjectSpinner
    android:id="@+id/spinner"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

Implement ObjectSpinner.Delegate on your object to override the getSpinnerDelegate() method to return the spinner’s delegate:

public class YourObject implements ObjectSpinner.Delegate {
  private String mCode;
  private String mName;
  ...

  @Override
  public String getSpinnerDelegate() {
    return mName;
  }
  ...
}

Add item list to the spinner and listen for select:

ObjectSpinner<YourObject> mObjectSpinner = findViewById(R.id.spinner);

List<YourObject> itemList = new ArrayList<>();

itemList.add(new YourObject("obj0001", "Object 1"));
itemList.add(new YourObject("obj0002", "Object 2"));
itemList.add(new YourObject("obj0003", "Object 3"));

mObjectSpinner.setItemList(itemList);

mObjectSpinner.setOnItemSelectedListener((view, position, item) -> {
  Snackbar.make(view, "Selected Object : " + item, Snackbar.LENGTH_SHORT).show();
});

mObjectSpinner.setOnNothingSelectedListener(view -> {
  Log.i(TAG, "onNothingSelected");
});

You can add attributes to customize the view. Available attributes:
