Android Toast Example

In Android, Toast is a notification message that pop up, display a certain amount of time, and automtaically fades in and out, most people just use it for debugging purpose.

Code snippets to create a Toast message :

//display in short period of time
Toast.makeText(getApplicationContext(), "msg msg", Toast.LENGTH_SHORT).show();
 
//display in long period of time
Toast.makeText(getApplicationContext(), "msg msg", Toast.LENGTH_LONG).show();

In this tutorial, we will show you two Toast examples :

1. Normal Toast view.
2. Custom Toast view.

P.S This project is developed in Eclipse 3.7, and tested with Android 2.3.3.

1. Normal Toast View

Simple Toast example.

File : res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
 
    <Button
        android:id="@+id/buttonToast"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Toast" />
 
</LinearLayout>

File : MainActivity.java

package com.mkyong.android;
 
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
 
public class MainActivity extends Activity {
 
 private Button button;
 
 public void onCreate(Bundle savedInstanceState) {
 
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
 
  button = (Button) findViewById(R.id.buttonToast);
 
  button.setOnClickListener(new OnClickListener() {
 
     @Override
     public void onClick(View arg0) {
 
        Toast.makeText(getApplicationContext(), 
                               "Button is clicked", Toast.LENGTH_LONG).show();
 
     }
  });
 }
}

See demo, when a button is clicked, display a normal Toast message.

2. Custom Toast View

Enchance above example by customize the original Toast view.

File : res/layout/custom_toast.xml – This is the custom Toast view.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/custom_toast_layout_id"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#FFF"
    android:orientation="horizontal"
    android:padding="5dp" >
 
    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_marginRight="5dp" />
 
    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:textColor="#000" />
 
</LinearLayout>

File : MainActivity.java – Read comment, to get above custom view and attach to Toast.

package com.mkyong.android;
 
import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
 
public class MainActivity extends Activity {
 
 private Button button;
 
 public void onCreate(Bundle savedInstanceState) {
 
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
 
  button = (Button) findViewById(R.id.buttonToast);
 
  button.setOnClickListener(new OnClickListener() {
 
   @Override
   public void onClick(View arg0) {
 
    // get your custom_toast.xml ayout
    LayoutInflater inflater = getLayoutInflater();
 
    View layout = inflater.inflate(R.layout.custom_toast,
      (ViewGroup) findViewById(R.id.custom_toast_layout_id));
 
    // set a dummy image
    ImageView image = (ImageView) layout.findViewById(R.id.image);
    image.setImageResource(R.drawable.ic_launcher);
 
    // set a message
    TextView text = (TextView) layout.findViewById(R.id.text);
    text.setText("Button is clicked!");
 
    // Toast...
    Toast toast = new Toast(getApplicationContext());
    toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(layout);
    toast.show();
   }
  });
 }
}

See demo, when a button is clicked, display the custom Toast message.
