Make a Toast in Android

What we will need ?

activity_main.xml
MainActivity.java

2 Toasts

2 Buttons

What we will do ?
-> We will display a long timed Toast when we will click on a button and a short timed when clicked on another button.

Step 1 : Make an android application Project with any name say ToastDemo.

Step 2 : Drag a button in activity_main.xml layout found in res->layout from the Palette.

The code for activity_main.xml is given below.

activity_main.xml

<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=".MainActivity" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="69dp"
        android:layout_marginTop="68dp"
        android:text="Long timed toast" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/button1"
        android:layout_below="@+id/button1"
        android:layout_marginTop="40dp"
        android:text="Short timed toast" />

</RelativeLayout>

Step 3 : Select MainActivity.java from src folder. Write the below code in the file.

MainActivity.java

package com.mia.toastdemo;

import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity {

    Button b1;
    Button b2;
   
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
        b1 = (Button) findViewById(R.id.button1);
        b2 = (Button) findViewById(R.id.button2);
       
b1.setOnClickListener(new OnClickListener() {
           
            public void onClick(View v) {
               
        Toast.makeText(getApplicationContext(), "long timed message", Toast.LENGTH_LONG).show();
    }
           
});

b2.setOnClickListener(new OnClickListener() {
   
    public void onClick(View v) {
       
Toast.makeText(getApplicationContext(), "short timed message", Toast.LENGTH_SHORT).show();
}
   
});
    }
}

Step 4 : Run the Project (Click on a Button and Toast will appear).
