本文介绍了一个Unity中的UI元素，用于显示聊天消息。该元素能够根据消息类型（文本或图片）调整布局，包括背景颜色、箭头颜色、文字宽度等，以适应不同消息的展示需求。

public class ListItem4 : MonoBehaviour
{
public Text mMsgText;
public Image mMsgPic;
public Image mIcon;
public Image mItemBg;
public Image mArrow;
public Text mIndexText;
int mItemIndex = -1;
float maxWidth;
private void Awake()
{
maxWidth = mMsgText.GetComponent<RectTransform>().sizeDelta.x;
}
public int ItemIndex
{
get
{
return mItemIndex;
}
}
public void Init()
{

}

public void SetItemData(ChatMsg itemData, int itemIndex)
{
mIndexText.text = itemIndex.ToString();
PersonInfo person = ChatMsgDataSourceMgr.Get.GetPersonInfo(itemData.mPersonId);
mItemIndex = itemIndex;
if (itemData.mMsgType == MsgTypeEnum.Str)
{
mMsgPic.gameObject.SetActive(false);
mMsgText.gameObject.SetActive(true);
mMsgText.text = itemData.mSrtMsg;

mIcon.sprite = ResManager.Get.GetSpriteByName(person.mHeadIcon);
float width = mMsgText.preferredWidth >= maxWidth ? maxWidth : mMsgText.preferredWidth;
float height = mMsgText.preferredHeight;
mMsgText.GetComponent<RectTransform>().sizeDelta = new Vector2(width, height);
mMsgText.GetComponent<ContentSizeFitter>().SetLayoutVertical();
Vector2 size = mMsgText.GetComponent<RectTransform>().sizeDelta + new Vector2(20, 20);
mItemBg.GetComponent<RectTransform>().sizeDelta = size;
if (person.mId == 0)
{
mItemBg.color = new Color32(160, 231, 90, 255);
mArrow.color = mItemBg.color;
}
else
{
mItemBg.color = Color.white;
mArrow.color = mItemBg.color;
}
RectTransform tf = gameObject.GetComponent<RectTransform>();
float y = size.y;
if (y < 75)
{
y = 75;
}
tf.SetSizeWithCurrentAnchors(RectTransform.Axis.Vertical, y);
}
else
{
mMsgPic.gameObject.SetActive(true);
mMsgText.gameObject.SetActive(false);
mMsgPic.sprite = ResManager.Get.GetSpriteByName(itemData.mPicMsgSpriteName);
mMsgPic.SetNativeSize();
mIcon.sprite = ResManager.Get.GetSpriteByName(person.mHeadIcon);
Vector2 size = mItemBg.GetComponent<RectTransform>().sizeDelta;
size.x = mMsgPic.GetComponent<RectTransform>().sizeDelta.x + 20;
size.y = mMsgPic.GetComponent<RectTransform>().sizeDelta.y + 20;
mItemBg.GetComponent<RectTransform>().sizeDelta = size;
if (person.mId == 0)
{
mItemBg.color = new Color32(160, 231, 90, 255);
mArrow.color = mItemBg.color;
}
else
{
mItemBg.color = Color.white;
mArrow.color = mItemBg.color;
}
RectTransform tf = gameObject.GetComponent<RectTransform>();
float y = size.y;
if (y < 75)
{
y = 75;
}
tf.SetSizeWithCurrentAnchors(RectTransform.Axis.Vertical, y);
