import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;

import java.util.ArrayList;
import java.util.List;

public class Spinner extends AppCompatActivity {

    android.widget.Spinner spinner;
    List<String> list;
    ArrayAdapter<String> SpinnerAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_spinner);
        spinner = (android.widget.Spinner) findViewById(R.id.spinner);
        list = new ArrayList<String>(); // List of Items
        list.add("Select your favorite city");

                (this, android.R.layout.simple_spinner_item, list){
            public View getView(int position, View convertView,
                                ViewGroup parent) {
                View v = super.getView(position, convertView, parent);
                ((android.widget.TextView) v).setTextColor(Color.parseColor("#009b9b"));
                return v;
            }
            public View getDropDownView(int position, View convertView,
                                        ViewGroup parent) {
                View v = super.getDropDownView(position, convertView,
                        parent);
                v.setBackgroundColor(Color.parseColor("#9A9393"));
                ((android.widget.TextView) v).setTextColor(Color.parseColor("#ffffff"));
                return v;
            }
        };
        SpinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(SpinnerAdapter);  // Set Adapter in the spinner
        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
                String state = parentView.getItemAtPosition(position).toString(); // selected item in the list
                ((TextView) findViewById(R.id.text)).setText(state);
            }
            @Override
            public void onNothingSelected(AdapterView<?> parentView) {

            }
        });
    }
}

•  Now Open res -> layout -> activity_main.xml and then add following code :

XML (activity_main.xml)

<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#F2F2F2"
    tools:context=".Spinner">
    <Spinner
        android:id="@+id/spinner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="left"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="18dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

Output:

Finally, run this project.
