In this tutorial I am going to discuss you about how to implement toast in android application .
A toast is just a kind o operation that show a simple small popup to the user for better user experience . It is used for showing messages in current activity for short intervals of time and the current activity remain visible .
Toasts automatically disappear after some duration of time . The default Toast’s view contains a TextView for showing messages on it.
Create a new project in Android Studio from File ⇒ New Project and select Empty Activity from templates to implement toast in android app .
1. Create a button to your main layout file :
Now we create a button to your main layout file i.e. activity_main.xml of your Main_Activity.java file or just implement the following xml code.
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/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Btn"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal"/>
</LinearLayout>
2. Now open your MainActivity.java and add following code :
Here we create a Toast with one of the makeText( ) methods. This method takes three parameters: the application Context , the text message, and the duration for the toast. It returns a properly initialised Toast message. You can display the toast notification with show( ) method .
package com.technxtcodelabs;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
Button btn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Create a Toast message here
Toast.makeText(getApplicationContext(),"Your message here",Toast.LENGTH_SHORT).show();
}
});
}
}
You can also customise toast with adding an image to it and changing size, colour of the message text .
Now run the project/app to test toast in android app through android device or any Emulator .
