Working with Spinner Android Studio Tutorial.

Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one.

                                                   

Here we have two spinners we will read spinner element using Array another with String.xml.Let's see the code for it.

MainActivity.java

package com.example.user.application2;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
    Spinner spinner1,spinner2;
    String[] Array={ "January","February","March","April","May","June","July","August","September","Octobe","November","December"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        spinner1 = (Spinner) findViewById(R.id.spinner1);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,Array);
       spinner1.setAdapter(adapter);
      spinner2 = (Spinner) findViewById(R.id.spinner2);
        ArrayAdapter adapter1 = ArrayAdapter.createFromResource(this,R.array.days,android.R.layout.simple_spinner_item);
        spinner2.setAdapter(adapter1);
        spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(MainActivity.this, ""+Array[position], Toast.LENGTH_SHORT).show();
           }
            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });


        spinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                TextView tv = (TextView) view;
                Toast.makeText(MainActivity.this, ""+tv.getText(), Toast.LENGTH_SHORT).show();
           }
            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
       });
   }
}

activity.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
   android:orientation="vertical"
    tools:context="com.example.user.application2.MainActivity">
   <Spinner
       android:id="@+id/spinner1"
       android:layout_marginTop="40dp"
       android:layout_width="match_parent"
       android:layout_height="wrap_content">
   </Spinner>
    <Spinner

        android:layout_width="match_parent"
