Awesome Android Spinner

With Awesome Spinner you can implement a material spinner with access to define direction layout and hint text.

Including the library

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency:

implementation 'com.github.sadra:AwesomeSpinner:1.5.1'

How To Use

Step 1. From very firts, you should add the Awsome Spinner component inside of your layout:

    <com.isapanah.awesomespinner.AwesomeSpinner
        android:id="@+id/my_spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

• If you want to add a default value for hint just add the spinnerHint into your component
• The default spinner has RTL direction, if you want to declare the direction of spinner just add the spinnerDirection to RTL or LTR so the complete example with LTR direction and hint text to Select a category is:

    <com.isapanah.awesomespinner.AwesomeSpinner
        android:id="@+id/my_spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:spinnerDirection="ltr"
        app:spinnerHint="Select a category" />

Step 2. Define the component class into your activity:

AwesomeSpinner my_spinner = (AwesomeSpinner) findViewById(R.id.my_spinner);

Then Create your adapter. For now, there is two way to define apadter:

• With String List, define a List<String> in your activity and the attach that with your adapter:

List<String> categories = new ArrayList<String>();
categories.add("Automobile");
categories.add("Ariplane");

ArrayAdapter<String> categoriesAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories);

my_spinner.setAdapter(categoriesAdapter);

• With String-Array, define a string-array in your strings.xml file and attach that with your adapter:

ArrayAdapter<CharSequence> provincesAdapter = ArrayAdapter.createFromResource(this, R.array.iran_provinces, android.R.layout.simple_spinner_item);

spinnerRTL.setAdapter(provincesAdapter, 0);

Step 3. For final step, you can create a Listener for listening on item selection:

my_spinner.setOnSpinnerItemClickListener(new AwesomeSpinner.onSpinnerItemClickListener<String>() {
    @Override
    public void onItemSelected(int position, String itemAtPosition) {
        //TODO YOUR ACTIONS
    }
});
