制作好APP在真機上運行時發現頁面總是略大于屏幕，查詢網上的解決方法，通過Android原生webview設置分辨率啦、縮放啦、自適應等等，沒啥用。后來看到X5WebView很多人贊，行吧，我也試試看好了。

走攻略下載X5WebView項目，主要從demo項目中復制下圖對應文件夾下的文件到我的項目中來。


在gradle.properties中加入代碼

android.useDeprecatedNdk=true

在build.gradle中defaultConfig {}塊中寫入代碼

ndk{abiFilters "armeabi", "armeabi-v7a", "x86", "mips"}

然后呢，寫一個類來使用X5WebView，在這里就要寫好WebView導入了，不然會和Android元素WebView混一起。

我需要做一個內嵌網頁的登錄和登出，登錄成功記住賬號和密碼，登出的時候登錄頁不顯示注冊頁而是老用戶登錄頁。

package com.example.com.hello1;import android.annotation.SuppressLint; import android.content.ActivityNotFoundException; import android.content.Context; import android.content.Intent; import android.graphics.Bitmap; import android.graphics.Color; import android.graphics.Rect; import android.text.TextUtils; import android.util.AttributeSet; import android.view.View; import com.tencent.smtt.sdk.WebSettings; import com.tencent.smtt.sdk.WebSettings.LayoutAlgorithm; import com.tencent.smtt.sdk.WebView; import com.tencent.smtt.sdk.WebViewClient; import java.net.URISyntaxException;public class X5WebView extends WebView {static boolean isx5Reset = false;static boolean delay = false;static String x5url = "";static boolean IS_NEED_CLAER = false;private WebViewClient client = new WebViewClient() {/*** 防止加載網頁時調起系統瀏覽器*/@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {WebView.HitTestResult hitTestResult = view.getHitTestResult();//hitTestResult==null解決重定向問題(刷新后不能退出的bug)if (!TextUtils.isEmpty(url) && hitTestResult == null) {return true;}if (shouldOverrideUrlLoadingByApp(view, url)) {return true;}return super.shouldOverrideUrlLoading(view, url);}@Overridepublic void onPageStarted(WebView view, String url, Bitmap favicon) {super.onPageStarted(view, url, favicon);}@Overridepublic void onPageFinished(WebView view, String url) {super.onPageFinished(view, url);//url.equals() 首頁網址后面如果沒有/結尾的話，該判斷總是返回falseif (url.equals(MainActivity.reurl)) { //限制只有首頁url操作if (MainActivity.USERNAME != "") view.loadUrl("javascript:(function() { document.getElementById('username').value='" + MainActivity.USERNAME + "';"+ "document.getElementById('password').value='" + MainActivity.PASSWORD + "';document.getElementsByClassName('Login')[0].style.display = 'block';document.getElementsByClassName('Register')[0].style.display = 'none';})()");//通過loadUrl進行JavaScript函數操作，進行元素的賦值、設置可見屬性}if (!delay) {delay = true;view.setBackgroundColor(Color.TRANSPARENT); //設置背景透明，這個可以處理加載網頁前的白屏，白屏閃一下在顯示頁面最討厭了view.setVisibility(View.VISIBLE); //之前設置了背景圖片，該web設置了隱藏，頁面加載完畢就把它顯示出來，且只執行一次，delay約束}if (url.equals("退登網址")) {MainActivity.getStr();//靜態重讀賬號和密碼的SharedPreferences數據view.loadUrl(MainActivity.reurl);//退登后馬上進入登錄頁面IS_NEED_CLAER = true;//清除訪問的歷史記錄}}@Overridepublic void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {super.onReceivedError(view, errorCode, description, failingUrl);// 在這里顯示自定義錯誤頁if (!isx5Reset) {//約束網絡異常時reset.html只加載一次isx5Reset = true;x5url = failingUrl;view.loadUrl("file:///android_asset/html/reset.html");}}@Overridepublic void doUpdateVisitedHistory(WebView view, String url, boolean isReload) {super.doUpdateVisitedHistory(view, url, isReload);if (IS_NEED_CLAER) {IS_NEED_CLAER = false;view.clearHistory();//清除歷史記錄}}};@SuppressLint("SetJavaScriptEnabled")public X5WebView(Context arg0, AttributeSet arg1) {//X5WebView初始化super(arg0, arg1);this.setWebViewClient(client);initWebViewSettings();this.getView().setClickable(true);}private void initWebViewSettings() {WebSettings mWebSettings = this.getSettings();mWebSettings.setJavaScriptEnabled(true);mWebSettings.setJavaScriptCanOpenWindowsAutomatically(true);mWebSettings.setAllowFileAccess(true);mWebSettings.setLayoutAlgorithm(LayoutAlgorithm.NARROW_COLUMNS);mWebSettings.setSupportZoom(true);mWebSettings.setBuiltInZoomControls(true);mWebSettings.setUseWideViewPort(true);mWebSettings.setSupportMultipleWindows(true);mWebSettings.setAppCacheEnabled(true);mWebSettings.setDomStorageEnabled(true);mWebSettings.setGeolocationEnabled(true);mWebSettings.setAppCacheMaxSize(Long.MAX_VALUE);mWebSettings.setPluginState(WebSettings.PluginState.ON_DEMAND);mWebSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);mWebSettings.setMixedContentMode(android.webkit.WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);}public X5WebView(Context arg0) {super(arg0);setBackgroundColor(85621);}/*** 根據url的scheme處理跳轉第三方app的業務*/private boolean shouldOverrideUrlLoadingByApp(WebView view, String url) {if (url.startsWith("http") || url.startsWith("https") || url.startsWith("ftp")) {//不處理http, https, ftp的請求return false;}Intent intent;try {intent = Intent.parseUri(url, Intent.URI_INTENT_SCHEME);} catch (URISyntaxException e) { // XLLog.e(TAG, "URISyntaxException: " + e.getLocalizedMessage());return false;}intent.setComponent(null);try {getContext().startActivity(intent);} catch (ActivityNotFoundException e) {//XLLog.e(TAG, "ActivityNotFoundException: " + e.getLocalizedMessage());return false;}return true;} }

載入X5內核的初始化需要定義MyApplication類，且AndroidManifest.xml中application的name名就為MyApplication。首次打開APP就需要成功加載X5內核，失敗則用原生的WebView

package com.example.com.hello1;import android.app.Application; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.support.annotation.Nullable;import com.tencent.smtt.sdk.QbSdk;public class MyApplication extends Application {@Overridepublic void onCreate() {super.onCreate();preinitX5WebCore();//預加載x5內核Intent intent = new Intent(this, AdvanceLoadX5Service.class);startService(intent);}private void preinitX5WebCore() {if (!QbSdk.isTbsCoreInited()) {QbSdk.preInit(getApplicationContext(), null);// 設置X5初始化完成的回調接口}}// x5 init servicepublic class AdvanceLoadX5Service extends Service {@Nullable@Overridepublic IBinder onBind(Intent intent) {return null;}@Overridepublic void onCreate() {super.onCreate();initX5();}private void initX5() {// 預加載X5內核QbSdk.initX5Environment(getApplicationContext(), cb);}QbSdk.PreInitCallback cb = new QbSdk.PreInitCallback() {@Overridepublic void onViewInitFinished(boolean arg0) {// TODO Auto-generated method stub//初始化完成回調}@Overridepublic void onCoreInitFinished() {// TODO Auto-generated method stub}};} }
