Android Toast Example

A toast displays a simple message in a small popup, which automatically disappear after a timeout. The code to display a Toast is:

Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();

Position of Toast: A standard toast notification appears near the bottom of the screen, centered horizontally. You can change this position with the setGravity(int, int, int) method. This accepts three parameters: a Gravity constant, an x-position offset, and a y-position offset. For example, if you decide that the toast should appear in the top-right corner, you can set the gravity like this:

toast.setGravity(Gravity.TOP|Gravity.RIGHT, 0, 0);

Now let’s create an app which Toast a message on button click.

Step 1: Create a new project and name it toastexample. Select File -> New -> New Project. Fill the forms and click “Finish” button.

Step 2: Open res -> layout -> xml (or) main.xml and add following code. Here we will create a Button in a LinearLayout.

<LinearLayout
    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"
    android:padding="10dp"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:background="#f00"
        android:padding="10dp"
        android:text="Show Toast"
        android:textColor="#fff"
        android:textStyle="bold" />
 
</LinearLayout>

Step 3: Open app -> java -> package and open MainActivity.java. Add following code in it. Here we will Toast a message “This is my toast” when the user clicks the Button.

package example.myandroid.toastexample;

import android.graphics.Color;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity {

    //Declare Button
    private Button button1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //Find Button using it's id from xml file
        button1 = (Button) findViewById(R.id.button1);

        //Set an onClickListener for the Button
        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //Toast a message when Button is clicked
                Toast.makeText(getApplicationContext(),"This is my toast", Toast.LENGTH_SHORT).show();
            }
        });
   }

}

Output:

Now run the app and click on the button. The app will show toast message “This is my toast”.
