How to show Toast in Android

If you want to show any message to the user then you need to show toast in android. This toast is just like a snack bar. You can also make a custom toast.

To display a message for a little information in your android application we use Toast class in android. An android toast displays a small message to the users.

We can say it's just a little information for the user for a few seconds and disappears after some time. Normally, the android toast is displayed at the bottom of the screen but you can also change display position and layout.

Android toast vs snackbar

Sometimes we need to show a piece of information to the user as a popup, but I can't use the bootstrap modal for that. So that time we need to create a Snackbar or we can say that a Toast message.

How To Create a Snackbar / Toast Bootstrap

First of all you require to add Toast class in your activity:

import android.widget.Toast;

Android toast duration

Generally, Toast is a popup for showing a piece of small information to the user, this is also using in the android application.

We can customize our Toast layout according to our requirements. It will be shown on the screen when you call it and It will disappear after a few seconds, whatever you have set.

There are two constants of Toast class which are given below for time duration.

Length Long

If you want to show any message to the user for a long duration, then you need to implement this on your toast setting.

Default duration for length long is 3.5 seconds.

LENGTH_LONG

you can use this just like:

Toast.LENGTH_LONG

Length Short

If you want to show any message to the user for a short duration, then you need to implement this on your toast setting.

Default duration for length long is 2 seconds.

LENGTH_SHORT

you can use this just like:

Toast.LENGTH_SHORT

Android Toast Example

Example for simple toast message:

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:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.legendblogs.demo.MainActivity">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Example of Toast"
        android:id="@+id/textView"
        android:layout_marginTop="91dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true" />
    <Button
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click me to get Toast"
        android:id="@+id/button"
        android:layout_marginTop="48dp"
        android:layout_below="@+id/textView"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

MainActivity.java:

package com.legendblogs.demo;
import android.content.Context;
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 {
    private Context context;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        this.context = this;
        Button button_toast = (Button) findViewById(R.id.button);
        button_toast.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(context,"Hello Legend Blogs User",Toast.LENGTH_SHORT).show();
            }
        });
    }
}

You can create your custom toast in android. By using XML layouts. So, just create an XML layout and attach layout with your Toast class object.
