Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.laurachelaru:MultiSelectSpinner:'
	}
	dependencies {
		implementation("com.github.laurachelaru:MultiSelectSpinner:")
	}
	<dependency>
	    <groupId>com.github.laurachelaru</groupId>
	    <artifactId>MultiSelectSpinner</artifactId>
	    <version></version>
	</dependency>

                            
    libraryDependencies += "com.github.laurachelaru" % "MultiSelectSpinner" % ""
        
        

                            
    :dependencies [[com.github.laurachelaru/MultiSelectSpinner ""]]

MultiSelect Spinner with Search/Filter:

How to use (WITHOUT FILTER):

/*  
* Getting array of String to Bind in Spinner
*/
final List<String> list = Arrays.asList(getResources().getStringArray(R.array.sports_array));
	
/**
* Simple MultiSelection Spinner (Without Search/Filter Functionlity)
* 
*  Using MultiSpinner class
*/	
MultiSpinner simpleSpinner = (MultiSpinner) findViewById(R.id.simpleMultiSpinner);

simpleSpinner.setItems(list, "Multi Selection Without Filter", -1, new MultiSpinnerListener() {
	
    @Override
public void onItemsSelected(boolean[] selected) {
		
		// your operation with code...
		for(int i=0; i<selected.length; i++) {
			if(selected[i]) {
				Log.i("TAG", i + " : "+ list.get(i));
			}
		}
	}
});

How to use (WITH FILTER):

/**
 * Search MultiSelection Spinner (With Search/Filter Functionality)
 * 
 *  Using MultiSpinnerSearch class
 */
MultiSpinnerSearch searchSpinner = (MultiSpinnerSearch) findViewById(R.id.searchMultiSpinner);
final List<KeyPairBoolData> listArray = new ArrayList<KeyPairBoolData>();

for(int i=0; i<list.size(); i++) {
	KeyPairBoolData h = new KeyPairBoolData();
	h.setId(i+1);
	h.setName(list.get(i));
	h.setSelected(false);
	listArray.add(h);
}

/***
 * -1 is no by default selection
 * 0 to length will select corresponding values 
 */
searchSpinner.setItems(listArray, "Multi Selection With Filter", -1, new MultiSpinnerSearchListener() {
	@Override
	public void onItemsSelected(List<KeyPairBoolData> items) {

		for(int i=0; i<items.size(); i++) {
			if(items.get(i).isSelected()) {
				Log.i("TAG", i + " : " + items.get(i).getName() + " : " + items.get(i).isSelected());
			}
		}
	}
});

(Optional) Limit setting

/**
 *  Using MultiSpinnerSearch object
 *  call setLimit method
 *  
 */
searchSpinner.setLimit(3, new MultiSpinnerSearch.LimitExceedListener() {
        @Override
        public void onLimitListener(KeyPairBoolData data) {
            Toast.makeText(getApplicationContext(),
                    "Limit exceed ", Toast.LENGTH_LONG).show();
        }
    });
