Toast.makeText(test.this,"bbb", Toast.LENGTH_LONG).show();
It doesn't work, how do I do it correctly?

คำตอบ:
To display the Toast in center of the screen.
Toast toast = Toast.makeText(test.this,"bbb", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 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.
ใน Xamarin Android สิ่งนี้จะแสดงขนมปังที่ตรงกลางหน้าจอ:
Toast toast = Toast.MakeText(ApplicationContext, "bbb", ToastLength.Long);
toast.SetGravity(GravityFlags.Center, 0, 0);
toast.Show();

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