Screen-Adaptive code for the UI in Unity

public void Screenuiselfadptation (Transform scaleui)
{
float widthrate = unityengine.screen.width/1920.0f;
float heightrate = unityengine.screen.height/1080.0f;
float postion_x = scaleui.getcomponent<recttransform> (). anchoredposition.x * widthrate;
float postion_y = scaleui.getcomponent<recttransform> (). ANCHOREDPOSITION.Y * heightrate;
Scaleui.localscale = new Vector3 (Widthrate, heightrate, 1);

Scaleui.getcomponent<recttransform> (). anchoredposition = new Vector2 (postion_x, postion_y);
}

UnityEngine.Screen.width and UnityEngine.Screen.height are the screen resolution sizes you want to publish.

1920.0f; x 1080.0f; is the resolution size in the Gam e view when you make the UI.
