解决Android中WebView跳转到浏览器的问题-USB迷|专注于互联网分享

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
