Displaying Toast Notification in Android

Toast notification is a mechanism in Android application to display a message for short duration to the user.The Toast notification is displayed on top of the current screen and occupies partial screen space.It is like a popup in windows applications.It goes away itself after a short duration.

To display toast notification in Android you need to call the following two methods of the Toast object:

• makeText()
• show()

To display the toast notification first create and set properties of the toast object using the following code:

Toast.makeText(context, message, length).show();

• context : Represents an activity
• message: Message that is to be displayed to the user

After this show the toast notification using the show() method:

toast.show();

Custom Toast Notification

Define the view to be used with toast:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/custom_toast"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textColor="#000000"
/>
</LinearLayout>

Use the LayoutInflater,which connects the view with the viewgroup, using the following code:

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_toast,
(ViewGroup) findViewById(R.id.container));

After this we are setting the text of the text layout by using the following code:

TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("This is a custom toast");

Finally we are creating a toast object:

Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();
