unity 内嵌h5页面跳转原生app

本文主要是介绍unity 内嵌h5页面跳转原生app，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

unity 内嵌H5界面需要用到Uniwebview 差件，百度搜索下就可以找到插件下载地址，这里就不提供了

Uniwebview 支持Android 、IOS。 PC平台下不显示，需要打包测试。

下面是封装好的动态加载外部网页类

using System;
using UnityEngine;public class WebView : Singleton<WebView> {public delegate void WebOnReceivedMessage(UniWebView webView, UniWebViewMessage message);public WebOnReceivedMessage OnWebReceivedMessage;#if !(UNITY_STANDALONE_OSX || UNITY_STANDALONE_WIN) private UniWebView webView;
#endifprivate Action onClose;private void CreateWebView(Rect panelPosition,Action loadFinished = null) {
#if !(UNITY_STANDALONE_OSX || UNITY_STANDALONE_WIN)if (this.webView == null) {this.webView = this.gameObject.AddComponent<UniWebView>();}          int top, left, bottom, right;
#if UNITY_ANDROIDleft = (int)panelPosition.x;top = (int)panelPosition.y;bottom = (int)(Screen.height - panelPosition.height - top);right = (int)(Screen.width - panelPosition.width - left) ;
#endif#if UNITY_IOSfloat ratio;ratio = 1f / UniWebViewHelper.screenScale;left = (int)(panelPosition.x * ratio);top = (int)(panelPosition.y* ratio);bottom = UniWebViewHelper.screenHeight - (int)((panelPosition.y+panelPosition.height)*ratio);right = UniWebViewHelper.screenWidth - (int)((panelPosition.x + panelPosition.width) * ratio);         
#endifthis.webView.insets = new UniWebViewEdgeInsets(top,left,bottom,right);Color bgColor = Color.white;bgColor.a = 0;this.webView.SetBackgroundColor(bgColor);this.webView.bouncesEnable = false;this.webView.SetShowSpinnerWhenLoading(true);if (loadFinished!=null) {this.webView.OnLoadComplete += (UniWebView webView, bool success, string errorMessage) => {this.webView.AddUrlScheme("http");this.webView.AddUrlScheme("https");loadFinished();};}this.webView.OnWebViewShouldClose += (view) => {return false;};this.webView.OnReceivedMessage += (webView, message) => {OnWebReceivedMessage(webView, message);UniWebviewTest.Instance.text.text = message.rawMessage;Application.OpenURL(message.rawMessage);};
#endif}public void Show(string url, Rect panelPosition, Action loadFinish = null,bool transition = false, Action onclosed = null) {#if UNITY_EDITOR || UNITY_STANDALONE_WINif (loadFinish != null) {loadFinish();}return;
#endif#if !(UNITY_STANDALONE_OSX || UNITY_STANDALONE_WIN) CreateWebView(panelPosition,loadFinish);this.webView.Load(url);this.webView.Show(true, transition ? UniWebViewTransitionEdge.Top : UniWebViewTransitionEdge.None, 0.3f);this.onClose = onclosed;  
#endif}public void Hide() {
#if !(UNITY_STANDALONE_OSX || UNITY_STANDALONE_WIN) if (this.webView == null) {return;}this.webView.Hide(true, UniWebViewTransitionEdge.None, 0.2f, () => {CloseWebView();});
#endif}private void CloseWebView() {
#if !(UNITY_STANDALONE_OSX || UNITY_STANDALONE_WIN) if (this.webView == null) {return;}this.webView.CleanCache();DestroyImmediate(this.webView);this.webView = null;this.onClose.Invoke();this.onClose = null;
#endif}}

Singleton单例

using UnityEngine;public abstract class Singleton<T> : MonoBehaviour where T : MonoBehaviour {private static T instance;// ReSharper disable once StaticMemberInGenericTypeprivate static readonly object Locker = new object();// ReSharper disable once StaticMemberInGenericTypeprivate static bool applicationIsQuitting;public static T Instance {get {if (Singleton<T>.applicationIsQuitting) {return null;}lock (Singleton<T>.Locker) {if (Singleton<T>.instance == null) {Singleton<T>.instance = Object.FindObjectOfType(typeof(T)) as T;if (Object.FindObjectsOfType(typeof(T)).Length > 1) {return Singleton<T>.instance;}if (Singleton<T>.instance == null) {GameObject singleton = new GameObject();Singleton<T>.instance = singleton.AddComponent<T>();singleton.name = "(singleton) " + typeof(T);Object.DontDestroyOnLoad(singleton);} else {}}return Singleton<T>.instance;}}}protected virtual void Awake() {Singleton<T>.applicationIsQuitting = false;}protected virtual void OnDestroy() {}private void OnApplicationQuit() {Singleton<T>.applicationIsQuitting = true;}
}

测试类

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;public class UniWebviewTest : MonoBehaviour {private WebView webView;public UnityEngine.UI.Text text;public static UniWebviewTest Instance;private string session_token = "45dbc533f2f47d9e693b621f0b2361a6";private string id = "10000";private void Awake() {Instance = this;}// Use this for initializationvoid Start () {Rect rect = new UnityEngine.Rect(this.GetComponent<RectTransform>().position, this.GetComponent<RectTransform>().rect.size);this.webView = Singleton<WebView>.Instance;this.webView.OnWebReceivedMessage += ReceivedMessage;this.webView.Show("http://192.168.18.57/pay.html",rect,() => { Debug.Log("H5"); });}private void ReceivedMessage(UniWebView webView, UniWebViewMessage message) {text.text = webView.url + ":" + message.path ;}}
