用到了腾讯x5的webview 当然原生的也可以
//腾讯x5 implementation 'com.tencent.tbs.tbssdk:sdk:43939' MyApplication->onCreate新增 我的是kt语法，，具体就是创建map添加进去
// 在调用TBS初始化、创建WebView之前进行如下配置 // 在调用TBS初始化、创建WebView之前进行如下配置 val map = mapOf(TbsCoreSettings.TBS_SETTINGS_USE_SPEEDY_CLASSLOADER to true,TbsCoreSettings.TBS_SETTINGS_USE_DEXLOADER_SERVICE to true) QbSdk.initTbsSettings(map)自定义webview
package com.anguomob.video.view import android.annotation.SuppressLint import android.content.Context import android.util.AttributeSet import com.tencent.smtt.sdk.WebSettings import com.tencent.smtt.sdk.WebView import com.tencent.smtt.sdk.WebViewClient class X5WebView @SuppressLint("SetJavaScriptEnabled") constructor( arg0: Context?, arg1: AttributeSet? ) : WebView(arg0, arg1) { private val client: WebViewClient = object : WebViewClient() { /** * 防止加载网页时调起系统浏览器 */ override fun shouldOverrideUrlLoading(view: WebView, url: String?): Boolean { view.loadUrl(url) return true } } private fun initWebViewSettings() { val webSetting: WebSettings = this.getSettings() webSetting.setJavaScriptEnabled(true) webSetting.setJavaScriptCanOpenWindowsAutomatically(true) webSetting.setAllowFileAccess(true) webSetting.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS) webSetting.setSupportZoom(true) webSetting.setBuiltInZoomControls(true) webSetting.setUseWideViewPort(true) webSetting.setSupportMultipleWindows(true) // webSetting.setLoadWithOverviewMode(true); webSetting.setAppCacheEnabled(true) // webSetting.setDatabaseEnabled(true); webSetting.setDomStorageEnabled(true) webSetting.setGeolocationEnabled(true) webSetting.setAppCacheMaxSize(Long.MAX_VALUE) // webSetting.setPageCacheCapacity(IX5WebSettings.DEFAULT_CACHE_CAPACITY); webSetting.setPluginState(WebSettings.PluginState.ON_DEMAND) // webSetting.setRenderPriority(WebSettings.RenderPriority.HIGH); webSetting.setCacheMode(WebSettings.LOAD_NO_CACHE) // this.getSettingsExtension().setPageCacheCapacity(IX5WebSettings.DEFAULT_CACHE_CAPACITY);//extension // settings 的设计 } init { this.setWebViewClient(client) // this.setWebChromeClient(chromeClient); // WebStorage webStorage = WebStorage.getInstance(); initWebViewSettings() this.getView().setClickable(true) } }总结
核心是因为下面的client没有设置 所以才跳转到 了系统默认浏览器 可以直接用webweb.setVewViewClient去设置一下就可以了
private val client: WebViewClient = object : WebViewClient() { /** * 防止加载网页时调起系统浏览器 */ override fun shouldOverrideUrlLoading(view: WebView, url: String?): Boolean { view.loadUrl(url) return true } } this.setWebViewClient(client)使用
