Toast is a transient notification that stays visible for a few seconds before fading out. It provides a simple feedback about an operation in a small popup without interrupting the application. We can use Toast for debugging purpose as well.
Toasts are excellent for informing our users of events without forcing them to open an Activity or browse a Notification. They provide a perfect mechanism for alerting users of events occurring in background services without interrupting the foreground applications. Generally, your application should show Toasts only if one of its Activities is active.
Creating Simple (Default) Android Toast :
The Toast class consists of a static make Text method that makes a standard Toast display window.
1. Open “MainActivity.java” file and add following JAVA code.
File :src/package-name/MainActivity.java
MainActivity.javaJava
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;
public class Main Activity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void SimpleToast(View view) {
// Call Toast to show msg
Toast.makeText(this, “Android Simple Toast”, Toast.LENGTH_LONG).show();
}
}
2. Open “res/layout/activity_main.xml” file and put this xml code it into file:
File : res/layout/activity_main.xml
activity_main.xml
XHTML
android:layout_width=”match_parent”
android:layout_height=”match_parent”
>
android:id=”@+id/tv_simple_toast”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:layout_marginTop=”10dp”
android:padding=”5dp”
android:text=”Android Simple Toast Example” />
android:id=”@+id/btn_click”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:layout_alignParentLeft=”true”
android:layout_alignParentRight=”true”
android:layout_below=”@+id/tv_simple_toast”
android:layout_marginTop=”41dp”
android:text=”Simple Toast Click”
android:onClick=”SimpleToast”/>
In Android Studio, create a new Toast, pass the current Context, the text message to show and also the length of your time to show (LENGTH_SHORT or LENGTH_LONG) into the make Text method. Once the Toast has been made, you’ll be able to show it by calling show.
Creating a Custom Toast View :
Sometimes a simple text message is not enough, we have to use a customized layout for our toast notification. To make a custom layout, define a view layout, in XML or in your application code and pass the root view object to the set View (View) method.
1. Create “res/layout/mycustom_toast.xml” file and put this xml code it into a file:
File : res/layout/mycustom_toast.xmlCustom_layout
android:orientation=”vertical” android:layout_width=”match_parent”
android:layout_height=”match_parent”
android:background=”#d4ffcd”
android:id=”@+id/custom”
>
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:background=”@drawable/sucess”
android:id=”@+id/iv_success” />
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
android:text=”RECORD SUCESSFULLY SAVED”
android:id=”@+id/tv_record”
android:layout_marginTop=”5dp”
android:textSize=”20dp”
android:layout_gravity=”center_horizontal”
android:layout_alignParentTop=”true”
android:layout_alignParentRight=”true”
android:layout_alignParentEnd=”true”
android:layout_toRightOf=”@+id/iv_success”
android:layout_toEndOf=”@+id/iv_success” />
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
android:text=”CUSTOM TOAST “
android:id=”@+id/tv_custom_toast”
android:textSize=”15dp”
android:layout_marginTop=”5dp”
android:layout_gravity=”center_horizontal”
android:layout_below=”@+id/tv_record”
android:layout_toRightOf=”@+id/iv_success”
android:layout_toEndOf=”@+id/iv_success” />
Custom Toast in java, that Layout of the Toast is “customtoast.xml” call by View.
My Custom Toast
R.id.btn_custom:
//get your custom_toast.xml layout
LayoutInflaterinflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.customtoast,null);
Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.BOTTOM, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();

By now, you should be able to create a Taost.
