Android Custom Toasts

In android, Toast is a small popup notification which is used to display an information about the operation which we performed in our app. The Toast will show the message for a small period of time and it will disappear automatically after a timeout.

 

Generally, the size of Toast will be adjusted based on the space required for the message and it will be displayed on the top of main content of an activity for a short period of time.

Generally, the Toast notification in android will be displayed with simple text like as shown in above image. In android, we can customize the layout of our toast notification to change the appearance of based on requirements like include images in toast notification or change the background colour of toast notification, etc.

 

Following is the pictorial representation of using Custom Toast notification in android applications.

To customize the appearance of Toast notification, we need to create a custom layout in our XML or application code and pass the root View object to the setView(View) method.

Create a Custom Toast in Android

To create a custom Toast notification in android, we need to define a custom View layout in XML, for that create a custom XML file (custom_toast.xml) in layout (/layout) folder and write the code like as shown below.

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   
android:id="@+id/custom_toast_container"
   
android:orientation="horizontal"
   
android:layout_width="match_parent"
   
android:layout_height="match_parent"
   
android:paddingLeft="10dp"
   
android:paddingRight="10dp"
   
android:background="#80CC28">
    <
ImageView android:src="@drawable/ic_notification"
       
android:layout_width="wrap_content"
       
android:layout_height="wrap_content"
       
android:layout_marginRight="10dp" />
    <
TextView android:id="@+id/txtvw"
       
android:layout_width="wrap_content"
       
android:layout_height="wrap_content"
       
android:layout_marginTop="13dp"
       
android:textColor="#FFF"
       
android:textStyle="bold"
       
android:textSize="15dp" />
</
LinearLayout>

To use this custom layout as Toast notification in our android application, we need to inflate the layout using following code.

 

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.
custom_toast, (ViewGroup) findViewById(R.id.custom_toast_layout));
TextView tv = (TextView) layout.findViewById(R.id.
txtvw);
tv.setText(
"Custom Toast Notification");
Toast toast =
new Toast(getApplicationContext());
toast.setDuration(Toast.
LENGTH_LONG);
toast.setView(layout);
toast.show();

If you observe above code, we created an instance of LayoutInflater with getLayoutInflater(), and then inflate our XML layout using inflate(int, ViewGroup). Here the first parameter is the layout resource ID and the second is the root View and this inflated layout will help us to find the View objects in the layout. After that we created a new Toast with Toast(Context) and set required properties of the toast, then we call setView(View) and pass it to the inflated layout.

 

Once we are done with required configurations, then we can show the custom toast notification by calling show() method.

 

Now we will see how to implement a custom Toast  notification in android applications with examples.

Android Custom Toast Example

Create a new android application using android studio and give names as ToastExample. In case if you are not aware of creating an app in android studio check this article Android Hello World App.

 

Now open an activity_main.xml file from \res\layout path and write the code like as shown below.

activity_main.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" >

    <
Button
       
android:id="@+id/btnShow"
       
android:layout_width="wrap_content"
       
android:layout_height="wrap_content"
       
android:text="Show Custom Toast"
       
android:layout_marginTop="150dp" android:layout_marginLeft="110dp"/>
</
LinearLayout>

If you observe above code we created a one Button control in XML Layout file to show the custom toast notification when we click on Button.

 

Now we need to create a custom layout for our toast notification, for that create a new xml file (custom_toast.xml) in /layout folder and write the code like as shown below.

Custom_toast.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   
android:id="@+id/custom_toast_layout"
   
android:orientation="horizontal"
   
android:layout_width="match_parent"
   
android:layout_height="match_parent"
   
android:paddingLeft="10dp"
   
android:paddingRight="10dp"
   
android:background="#80CC28">
    <
ImageView android:src="@drawable/ic_notification"
       
android:layout_width="wrap_content"
       
android:layout_height="wrap_content"
       
android:layout_marginRight="10dp" />
    <
TextView android:id="@+id/txtvw"
       
android:layout_width="wrap_content"
       
android:layout_height="wrap_content"
       
android:layout_marginTop="13dp"
       
android:textColor="#FFF"
       
android:textStyle="bold"
       
android:textSize="15dp" />
</
LinearLayout>

If you observe above code we are loading image (ic_notification) from drawable folder so you need to add your icon in drawable folder to show it in notification. 

 

Once we are done with creation of layout with required controls, we need to load the XML layout resource from our activity onCreate() callback method, for that open main activity file MainActivity.java from \java\com.tutlane.toastexample path and write the code like as shown below.

MainActivity.java

package com.tutlane.customtoastexample;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
   
@Override
   
protected void onCreate(Bundle savedInstanceState) {
       
super.onCreate(savedInstanceState);
        setContentView(R.layout.
activity_main);
        Button btn = (Button)findViewById(R.id.
btnShow);
        btn.setOnClickListener(
new View.OnClickListener() {
           
@Override
           
public void onClick(View v) {
                LayoutInflater inflater = getLayoutInflater();
                View layout = inflater.inflate(R.layout.
custom_toast, (ViewGroup) findViewById(R.id.custom_toast_layout));
                TextView tv = (TextView) layout.findViewById(R.id.
txtvw);
                tv.setText(
"Custom Toast Notification");
                Toast toast =
new Toast(getApplicationContext());
                toast.setGravity(Gravity.
CENTER_VERTICAL, 0, 100);
                toast.setDuration(Toast.
LENGTH_LONG);
                toast.setView(layout);
                toast.show();
            }
        });
    }
}

If you observe above code we are calling our custom toast notification by using LayoutInflater object and showing a toast notification on Button click.

 

Generally, during the launch of our activity, onCreate() callback method will be called by android framework to get the required layout for an activity.

Output of Android Custom Toast Example

When we run above example using android virtual device (AVD) we will get a result like as shown below.

 

Android Custom Toast Notification Example Result

 

If you observe above result we created a custom toast notification and showing it on Button click based on our requirements.

 

This is how we can create custom toast notifications in android applications based on our requirements.
