我在百川sdk的旺旺群中，追问这个问题N多次，一直没有人答复，哎，凡事都要靠自己.....
1、先查看下百川sdk中，是怎么处理咱们传递过去的 WebViewClient
public class l implements WebViewService {
private static final String b = l.class.getSimpleName();
private static final String c;
private static final String d;
private String e;
public static boolean a;
private String f = "";
private String g;
private HashMap<String, String> h = new HashMap();
public l() {
}
public void bindWebView(WebView var1, WebViewClient var2) {
if(var1 != null) {
a = false;
WebSettings var5 = var1.getSettings();
try {
var5.setJavaScriptEnabled(true);
} catch (Exception var7) {
;
}
var5.setSavePassword(false);
var5.setUseWideViewPort(true);
var5.setLoadWithOverviewMode(true);
var5.setJavaScriptCanOpenWindowsAutomatically(false);
var5.setDomStorageEnabled(true);
this.g = var1.getContext().getApplicationContext().getDir("cache", ).getPath();
var5.setAppCachePath(this.g);
var5.setAllowFileAccess(true);
var5.setAppCacheEnabled(true);
if(CommonUtils.isNetworkAvailable(var1.getContext())) {
var5.setCacheMode(-);
} else {
var5.setCacheMode();
}
var5.setBuiltInZoomControls(false);
StringBuilder var6 = new StringBuilder();
this.e = var5.getUserAgentString();
if(this.e != null) {
var6.append(this.e);
}
if(!WebViewUtils.isLoginDowngraded()) {
var6.append(d);
}
var6.append(c);
var5.setUserAgentString(var6.toString());
if(VERSION.SDK_INT >= ) {
CookieManager.getInstance().setAcceptThirdPartyCookies(var1, true);
int var10000 = d.e == null?-:d.e.getIntValue("mixedContentMode", -);
int var8 = var10000;
if(var10000 != -) {
var5.setMixedContentMode(var8);
}
}
if(var2 == null) {
var1.setWebViewClient(new m(this));
} else {
var1.setWebViewClient(new n(this));
}
}
}
public void releaseWebView(WebView var1) {
var1.getSettings().setUserAgentString(this.e);
d.m.removeCookies();
}
protected static void a(String var0) {
if(!WebViewUtils.isLoginDowngraded()) {
try {
CookieManagerWrapper.INSTANCE.refreshCookie(var0);
} catch (Exception var1) {
AliSDKLogger.e("ui", "fail to refresh cookie", var1);
}
}
}
static {
c = " AliApp(BC/" + ConfigManager.TAE_SDK_VERSION.toString() + ")";
d = " tae_sdk_" + ConfigManager.SDK_INTERNAL_VERSION;
a = false;
}
}关键在 bindWebView(WebView var1, WebViewClient var2) 方法中 var2 做了些什么！！...
if(var2 == null) {
var1.setWebViewClient(new m(this));
} else {
var1.setWebViewClient(new n(this));
}哇擦擦，只是用来判断，连基本的保存都没有。可想我的 WebViewClient 死的多惨。
既然百川不带咱们的 WebViewClient 玩，那就想想其他办法，它不带咱们玩，那就咱们带它玩吧....
那怎么玩呢？咱们的 WebViewClient 来包裹百川的 WebViewClient ，然后在通过 webView.setWebViewClient 方法把新的 WebViewClient 重新设置进去。
具体实现如下
1、首先绑定百川的 WebView 服务
mWebViewService = AlibabaSDK.getService(WebViewService.class);
mWebViewService.bindWebView(webView, null);
2、通过反射从系统的 WebView 获得百川的 WebViewClient
/** 获得隐藏成员变量mProvider中的WebViewClient */
public WebViewClient getProviderWebViewClient() {
WebViewClient webViewClient = null;
try {
Class<?> cls = this.getClass();
Method method = cls.getMethod("getWebViewProvider");
method.setAccessible(true);
Object object = method.invoke(this); // object => WebViewChromium implements WebViewProvider
Field field = object.getClass().getDeclaredField("mContentsClientAdapter");
field.setAccessible(true);
object= field.get(object); // object => WebViewContentsClientAdapter
field = object.getClass().getDeclaredField("mWebViewClient");
field.setAccessible(true);
object= field.get(object);
if (object instanceof WebViewClient) { webViewClient = (WebViewClient) object; }
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (NoSuchFieldException e) {
e.printStackTrace();
} finally { return webViewClient; }
}
3、将自己的WebViewClient 和百川的WebViewClient 结合
package com.emar.bcsdk; import android.annotation.TargetApi;
import android.graphics.Bitmap;
import android.net.http.SslError;
import android.webkit.SslErrorHandler;
import android.webkit.WebView;
import android.webkit.WebViewClient; /**
* Created by ak_star on 2016/6/2.
*/
public class MixBaiCWebViewClient extends WebViewClient {
private WebViewClient mMyselfClient = null; // 自己应用的WebViewClient
private WebViewClient mBaiCClient = null; // 百川WebViewClient public MixBaiCWebViewClient(WebViewClient myself, WebViewClient baiClient) {
mMyselfClient = myself;
mBaiCClient = baiClient;
} @Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
super.onReceivedError(view, errorCode, description, failingUrl);
if (mBaiCClient != null) { mBaiCClient.onReceivedError(view, errorCode, description, failingUrl); }
if (mMyselfClient != null) { mMyselfClient.onReceivedError(view, errorCode, description, failingUrl); }
} @Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
if (mBaiCClient != null) { mBaiCClient.onPageStarted(view, url, favicon); }
if (mMyselfClient != null) { mMyselfClient.onPageStarted(view, url, favicon); }
} @Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
if (mBaiCClient != null) { mBaiCClient.onPageFinished(view, url); }
if (mMyselfClient != null) { mMyselfClient.onPageFinished(view, url); }
} @Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
boolean result = super.shouldOverrideUrlLoading(view, url);
if (mMyselfClient != null)
result = mMyselfClient.shouldOverrideUrlLoading(view, url);
if (mBaiCClient != null) {
if (!result) {
result = mBaiCClient.shouldOverrideUrlLoading(view, url);
} else { mBaiCClient.shouldOverrideUrlLoading(view, url); }
}
return result;
} @TargetApi()
@Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
super.onReceivedSslError(view, handler, error);
if (mBaiCClient != null) {
mBaiCClient.onReceivedSslError(view, handler, error);
} else if (mMyselfClient != null) {
mMyselfClient.onReceivedSslError(view, handler, error);
}
}
}
4、最后重新设置给 WebView
webView.setWebViewClient(new MixBaiCWebViewClient(client, baiCWebViewClient));
上述方案已经经过本人测试，可以实现 淘宝授权免登服务，同时也触发了自己的 WebViewClient 中的方法执行。
但毕竟此方案不是正规途径，有正规方法，还是用正规方法。
注意：1、此方法再升级百川sdk后，要重新检查是否仍然可行
2、由于使用了反射，android sdk 如果变量名称、类型改变也可能失效，需要重新确定反射对象。
