How to show Toast on Button Click | Android Studio 2.2.1 Tutorial

A toast provides simple feedback about an operation in a small popup. It only fills the amount of space required for the message and the current activity remains visible and interactive. Toasts automatically disappear after a timeout.

How to do ?

Add a button in activity_main.xml

 <?xml version="1.0" encoding="utf-8"?>  
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   xmlns:tools="http://schemas.android.com/tools"  
   android:id="@+id/activity_main"  
   android:layout_width="match_parent"  
   android:layout_height="match_parent"  
   android:paddingBottom="@dimen/activity_vertical_margin"  
   android:paddingLeft="@dimen/activity_horizontal_margin"  
   android:paddingRight="@dimen/activity_horizontal_margin"  
   android:paddingTop="@dimen/activity_vertical_margin"  
   android:background="@android:color/white"  
   tools:context="com.sabithpkcmnr.toast.MainActivity">  
   <Button  
     android:id="@+id/bt"  
     android:layout_width="wrap_content"  
     android:layout_height="wrap_content"  
     android:text="Click to Toast"  
     android:layout_centerVertical="true"  
     android:layout_centerHorizontal="true" />  
 </RelativeLayout>  

MainActivity

 package com.sabithpkcmnr.toast;  
   
 import android.support.v7.app.AppCompatActivity;  
 import android.os.Bundle;  
 import android.view.View;  
 import android.widget.Button;  
 import android.widget.Toast;  
   
 public class MainActivity extends AppCompatActivity {  
   Button btn;  
   @Override  
   protected void onCreate(Bundle savedInstanceState) {  
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.activity_main);  
     btn = (Button) findViewById(R.id.bt);  
     btn.setOnClickListener(new View.OnClickListener() {  
       @Override  
       public void onClick(View v) {  
         Toast.makeText(getApplicationContext(),"Here is my Toast Text",Toast.LENGTH_LONG).show();  
       }  
     });  
   }  
 }

we had shown the Toast programmatically in MainActivity


That's it.
Thanks for your time
