How To display a simple Toast Notificatin in Android

To create a simple Toast Notification instantiate a Toast object passing the context, the text and the duration to its makeText() method, then call the show() method. The duration can be : Toast.LENGTH_LONG or Toast.LENGTH_SHORT.
Example:

Context context = getApplicationContext();
CharSequence text = "Write the toast message here";
int duration = Toast.LENGTH_SHORT;
Toast toastNodification = Toast.makeText(context, text, duration);
toastNodification.show();

You can also use the short (chained) version :

Toast.makeText(getApplicationContext(), "short version", Toast.LENGTH_SHORT).show();

Don't forget to add imports:

import android.content.Context;
import android.widget.Toast;

The result:


Complete code :

main.java

package com.blog.simpletoastnotification;

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

public class main extends Activity {
 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  Button simpleBtn = (Button) findViewById(R.id.button1);
  simpleBtn.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    Context context = getApplicationContext();
    CharSequence text = "Write the toast message here";
    int duration = Toast.LENGTH_SHORT;
    Toast toastNodification = Toast.makeText(context, text, duration);
    toastNodification.show();
    
    // short version
   // Toast.makeText(getApplicationContext(),
"short version Toast", Toast.LENGTH_SHORT).show();
   }
  });

 }
}
