Unity UI适配屏幕心得

安卓版本apk UI 适配问题：

适配原理：

效果：

的
1：1024*768

2：1920*1080

void OnGUI(){print("--GUI--");switch (SlideAnctor){case Slide.Bottom:gameObject.transform.localPosition = new Vector3(0 + Deviation_Value.x, -Screen.height / 2 + Deviation_Value.y, 0);break;case Slide.Center:gameObject.transform.localPosition = new Vector3(0 + Deviation_Value.x, 0 + Deviation_Value.y, 0);break;case Slide.CenterLeft:gameObject.transform.localPosition = new Vector3(Screen.width / 2 + Deviation_Value.x, 0 + Deviation_Value.y, 0);break;case Slide.CenterRigth:gameObject.transform.localPosition = new Vector3(-Screen.width / 2 + Deviation_Value.x, 0 + Deviation_Value.y, 0);break;case Slide.Top:gameObject.transform.localPosition = new Vector3(0 + Deviation_Value.x, Screen.height / 2 + Deviation_Value.y, 0);gameObject.transform.localPosition = new Vector3(0 + Deviation_Value.x, Screen.height / 2 + Deviation_Value.y, 0);break;case Slide.TopLeft:gameObject.transform.localPosition = new Vector3(-Screen.width / 2 + Deviation_Value.x, Screen.height / 2 + Deviation_Value.y, 0);break;case Slide.TopRight:gameObject.transform.localPosition = new Vector3(Screen.width / 2 + Deviation_Value.x, Screen.height / 2 + Deviation_Value.y, 0);break;case Slide.BottomLeft:gameObject.transform.localPosition = new Vector3(-Screen.width / 2 + Deviation_Value.x, -Screen.height / 2 + Deviation_Value.y, 0);break;case Slide.BottomRight:gameObject.transform.localPosition = new Vector3(Screen.width / 2 + Deviation_Value.x, -Screen.height / 2 + Deviation_Value.y, 0);break;}// print(gameObject.transform.localPosition);switch (style){case Style.NormalBehavior:break;case Style.Both:sceenValue = new Vector2(Screen.width, Screen.height);gameObject.GetComponent<RectTransform>().sizeDelta = sceenValue;break;case Style.Heigth:sizeDelta = gameObject.GetComponent<RectTransform>().sizeDelta;sizeValue = sizeDelta.x * (Screen.height / sizeDelta.y);gameObject.GetComponent<RectTransform>().sizeDelta = new Vector2(sizeValue, Screen.height);break;case Style.Width:sizeDelta = gameObject.GetComponent<RectTransform>().sizeDelta;sizeValue = sizeDelta.y * (Screen.width / sizeDelta.x);gameObject.GetComponent<RectTransform>().sizeDelta = new Vector2(Screen.width, sizeValue);break;case Style.proportion:sizeDelta = gameObject.GetComponent<RectTransform>().sizeDelta;sizeDelta = sizeDelta * value; print("1:" + value);gameObject.GetComponent<RectTransform>().sizeDelta = sizeDelta;break;}_isActor = true;}

2；像素改变：

/*
获取原始UI像素，保存，初始化需要原始数据
*/
public void GetSizeDelta(){sizeDelta = new List<Vector2>();ratioSceen = new List<Vector2>();//gameObject.tag = "Stretching";Vector2 size = new Vector2();if (Stretching.Count > 0){foreach (GameObject g in Stretching){g.tag = "Stretching";size = g.GetComponent<RectTransform>().sizeDelta;ratioSceen.Add(new Vector2(size.x / layoutScale.x, size.y / layoutScale.y));sizeDelta.Add(size);if (!sizeDic.ContainsKey(g))sizeDic.Add(g, size);elsesizeDic[g] = size;}}}/*
摆放屏幕：实际的屏幕
*/public void SetSizeDelta(Vector2 stretch){Vector2 size = new Vector2();nowSizeDelta = new List<Vector2>();if (stretch.x > stretch.y){if (stretch.y > 2){// return;}else{//如果长、宽比例差太多，取1.3做比例值（初始UI设计的高宽比例大概1.3，如果长或者宽拉的过于大，图片失真的会很明显）if (stretch.x / stretch.y > 1.3f){stretch.x = stretch.y * 1.3f;}int v1 = (Mathf.FloorToInt((stretch.x/stretch.y) * 10));float v = v1 * 0.1f;foreach (GameObject g in sizeDic.Keys){size = new Vector2(sizeDic[g].x * v, sizeDic[g].y);nowSizeDelta.Add(size);g.GetComponent<RectTransform>().sizeDelta = size;}print(v);}}else if (stretch.y > stretch.x){if (stretch.x > 2){}else{//如果长、宽比例差太多，取1.3做比例值if (stretch.x / stretch.y > 1.3f){stretch.x = stretch.y * 1.3f;}int v1 = (Mathf.FloorToInt((stretch.x / stretch.y) * 10));float v = v1 * 0.1f;foreach (GameObject g in sizeDic.Keys){size = new Vector2(sizeDic[g].x, sizeDic[g].y * v);nowSizeDelta.Add(size);g.GetComponent<RectTransform>().sizeDelta = size;}}print("c2:" + stretch);}else{int i = 0;foreach (GameObject g in sizeDic.Keys){g.GetComponent<RectTransform>().sizeDelta = sizeDelta[i];i++;}}}

3，位置移动

/*
获取原始UI位置
*/
public void GetDisplacementObject(){displacement = new List<GameObject>();displacementPos = new List<Vector3>();displaceDic = new Dictionary<GameObject, Vector3>();if (displacementParent.Count>0){int count = 0;GameObject game;foreach (GameObject g in displacementParent){count = g.transform.childCount;for (int i = 0; i < count; i++){if (g.transform.GetChild(i).gameObject.tag == "Displacement"){game = g.transform.GetChild(i).gameObject;displacement.Add(game);displacementPos.Add(game.transform.localPosition);if (displaceDic.ContainsKey(game)){displaceDic[game] = game.transform.localPosition;}elsedisplaceDic.Add(game, game.transform.localPosition);}}}}else{int count = gameObject.transform.childCount;GameObject game;for (int i = 0; i < count; i++){if (gameObject.transform.GetChild(i).gameObject.tag == "Displacement"){game = gameObject.transform.GetChild(i).gameObject;displacement.Add(game);displacementPos.Add(game.transform.localPosition);if (displaceDic.ContainsKey(game)){displaceDic[game] = game.transform.localPosition;}elsedisplaceDic.Add(game, game.transform.localPosition);}}}}
/*
屏幕像素变了，一些UI的位置也是需要调整
*/public void DisplacementValue(Vector2 stretch){ if (stretch.x > stretch.y){if (stretch.y > 2){}else{if (stretch.x / stretch.y > 1.3f){stretch.x = stretch.y * 1.3f;}//int v0 = (Mathf.FloorToInt((stretch.x - stretch.y + 1) * 100));int v1 = (Mathf.FloorToInt((stretch.x / stretch.y) * 10));float v = v1 * 0.1f;foreach (GameObject g in displaceDic.Keys){g.transform.localPosition = new Vector3(displaceDic[g].x * v, displaceDic[g].y, displaceDic[g].z);}}}else if (stretch.y > stretch.x){/*if (stretch.y > 2)return;*/if (stretch.y / stretch.x > 1.3f){stretch.y = stretch.x * 1.3f;}//int v0 = (Mathf.FloorToInt((stretch.y - stretch.x + 1) * 100));int v1 = (Mathf.FloorToInt((stretch.x / stretch.y) * 10));float v = v1 * 0.1f;foreach (GameObject g in displaceDic.Keys){g.transform.localPosition = new Vector3(displaceDic[g].x, displaceDic[g].y * v, displaceDic[g].z);}}else {foreach (GameObject g in displaceDic.Keys){g.transform.localPosition = displaceDic[g];}}}

心得：

效果目前看着还可以，这个项目可能效果还行，但是拿出到其他项目可能会有很多其他的问题，希望能得到更多的人的修改意见，然后可以修改成比较好的适配效果，主要是想有其他思路。
