A toast provides simple feedback about an operation in a small popup. It only fills the amount of space required for the message and the current activity remains visible and interactive. Toasts automatically disappear after a timeout.

For example, clicking Send on an email triggers a "Sending message..." toast, as shown in the following screen capture:

Toasts are not clickable. If user response to a status message is required, consider instead using a Notification.

The Basics

First, instantiate a Toast object 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 initialized Toast object. You can display the toast notification with show() , as shown in the following example:

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

This example demonstrates everything you need for most toast notifications. You should rarely need anything else. You may, however, want to position the toast differently or even use your own layout instead of a simple text message. The following sections describe how you can do these things.

You can also chain your methods and avoid holding on to the Toast object, like this:

Kotlin Toast.makeText(context, text, duration).show() Java Toast.makeText(context, text, duration).show();

Positioning your 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-left corner, you can set the gravity like this:

Kotlin toast.setGravity(Gravity.TOP or Gravity.LEFT, 0, 0) Java toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);

If you want to nudge the position to the right, increase the value of the second parameter. To nudge it down, increase the value of the last parameter.

Creating a Custom Toast View

If a simple text message isn't enough, you can create a customized layout for your toast notification. To create a custom layout, define a View layout, in XML or in your application code, and pass the root View object to the setView(View) method.

The following snippet contains a customized layout for a toast notification (saved as layout/custom_toast.xml ):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/custom_toast_container" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="8dp" android:background="#DAAA" > <ImageView android:src="@drawable/droid" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="8dp" /> <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#FFF" /> </LinearLayout>

Notice that the ID of the LinearLayout element is "custom_toast_container". You must use this ID and the ID of the XML layout file "custom_toast" to inflate the layout, as shown here:

Kotlin val inflater = layoutInflater val container: ViewGroup = findViewById(R.id.custom_toast_container) val layout: ViewGroup = inflater.inflate(R.layout.custom_toast, container) val text: TextView = layout.findViewById(R.id.text) text.text = "This is a custom toast" with (Toast(applicationContext)) { setGravity(Gravity.CENTER_VERTICAL, 0, 0) duration = Toast.LENGTH_LONG view = layout show() } Java LayoutInflater inflater = getLayoutInflater(); View layout = inflater.inflate(R.layout.custom_toast, (ViewGroup) findViewById(R.id.custom_toast_container)); TextView text = (TextView) layout.findViewById(R.id.text); text.setText("This is a custom toast"); Toast toast = new Toast(getApplicationContext()); toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0); toast.setDuration(Toast.LENGTH_LONG); toast.setView(layout); toast.show();

First, retrieve the LayoutInflater with getLayoutInflater() (or getSystemService() ), and then inflate the layout from XML using inflate(int, ViewGroup) . The first parameter is the layout resource ID and the second is the root View. You can use this inflated layout to find more View objects in the layout, so now capture and define the content for the ImageView and TextView elements. Finally, create a new Toast with Toast(Context) and set some properties of the toast, such as the gravity and duration. Then call setView(View) and pass it the inflated layout. You can now display the toast with your custom layout by calling show() .
