In Android I want to display a toast message at the bottom of the screen, I tried this:

Toast.makeText(test.this,"bbb", Toast.LENGTH_LONG).show();

It doesn't work, how do I do it correctly?

In Xamarin.Android, this displays toast at center of screen:

            Toast toast = Toast.MakeText(ApplicationContext, "bbb", ToastLength.Long);
            toast.SetGravity(GravityFlags.Center, 0, 0);
            toast.Show();

The below code worked for me.

Toast.makeText(this, "Toast in center", Toast.LENGTH_SHORT).setGravity(Gravity.CENTER,0,0).show();

Layout file for custom toast

<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" />

.java file for custom toast on button's click event

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();
        }
    });
}

}

Toast toast = new Toast(context);
        toast.setGravity(Gravity.FILL_HORIZONTAL | Gravity.BOTTOM, 0, 0);
toast.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:

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.
