我的网络视图在果冻豆和kitkat版本中搞砸了，但在棒棒糖和更高版本中效果很好.我该怎么把它做成果冻豆和泡菜

Question

下面是我的代码：

public void mywebview(){
try {
    webview.setBackgroundColor(0);
    webview.getSettings().setJavaScriptEnabled(true);
    webview.addJavascriptInterface(new MyJavaScriptInterface(), "MYOBJECT");
    webview.getSettings().setAllowUniversalAccessFromFileURLs(true);
    webview.getSettings().setUseWideViewPort(true);
    webview.getSettings().setLoadWithOverviewMode(true);
    webview.getSettings().setBuiltInZoomControls(true);
    webview.getSettings().setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
    webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    webview.getSettings().setAllowFileAccess(true);
    webview.canScrollHorizontally(1);
    webview.setInitialScale(1);
    webview.getSettings().setDefaultFontSize(2);
    webview.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            webview.setHorizontalScrollBarEnabled(true);
            webview.setInitialScale(1);
            return false;
        }
    });
    webview.setWebViewClient(new WebViewClient() {

        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(view.getContext(), "Authentication Error", Toast.LENGTH_LONG).show();
            CookieManager cookieManager = CookieManager.getInstance();
            cookieManager.setCookie(USERNAME, PASSWORD);
            super.onReceivedError(view, errorCode, description, failingUrl);
        }
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return super.shouldOverrideUrlLoading(view, url);
            }
        }
        public void onReceivedHttpAuthRequest(WebView view, HttpAuthHandler handler, String host, String realm) {
        }
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
            SharedPreferencesManager mgr = SharedPreferencesManager.getInstance();
            StringBuilder stringBuilder = new StringBuilder();
            DefaultHttpClient client = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet(URL);
            try {
                HttpResponse response = client.execute(httpGet);
                StatusLine statusLine = response.getStatusLine();
                int statusCode = statusLine.getStatusCode();
                if (statusCode == 200) {
                }
            } catch (Exception e) {
            }
            CookieStore cookieStore = mgr.getCookieStore();
            Cookie cookie = cookieStore.getCookies().get(1);
            CookieManager cookieMgr = CookieManager.getInstance();
            cookieMgr.setCookie(url, cookie.getName() + "=" + cookie.getValue());
            CookieSyncManager.getInstance().sync();
            return super.shouldInterceptRequest(view, url);
        }
    });
    webCookieManager = CookieManager.getInstance();
    webCookieManager.setAcceptCookie(true);
    CookieStore cookieStore = mgr.getCookieStore();
    Cookie cookie = cookieStore.getCookies().get(1);
    webCookieManager.setCookie(URL, cookie.getName() + "=" + cookie.getValue() + ";");
    CookieSyncManager.getInstance().sync();
    webview.loadUrl(URL);
} catch (Exception e) {
    e.printStackTrace();
}
}

看起来webresourceresponse只兼容棒棒糖版本及以上版本。有没有一种方法可以修复它，使其适用于较低版本，即果冻豆和kitkat？此外，我所说的"混乱"是指它看起来都垂直对齐，塞进一个视图中，不像棒棒糖+版本，视图看起来像预期的那样组织得很好。这是我的xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/myholder"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000"
     >
 <WebView
        android:id="@+id/my_webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
</RelativeLayout>

Answer 1

我认为没有办法改变这一点，除非你使用旧的方法来处理旧的API参见此

Answer 2

最好/唯一的方法是编写特定于版本的代码，一个用于jelly-bean和kitkat，另一个用于lollypop及以上版本。我还没有研究过让它在较低版本上工作的代码，但处理它的方法是检查SDK版本，并执行特定版本的代码。

示例：（代码修改自：如何在您的代码中支持多个android版本？）

// System information
private final int sdkVersion = Build.VERSION.SDK_INT;
// If you want to go really old:
// (actually, there is a question about how this issue should be handled
// systematically. Suggestions welcome.)
// final int sdkVersion = Integer.parseInt(Build.VERSION.SDK);
// For meaning of other variable, see notification documentation on the android website.
if (sdkVersion > Build.VERSION_CODES.LOLLIPOP) {
    myWebviewForLollipopAndAbove webview = new myWebviewForLollipopAndAbove();
    //Do things with the webview, finish implementing
}
else {
    myWebviewForBelowLollipop webview = new myWebviewForBelowLollipop();
    //Do things with the webview, finish implementing
}

显然，这段代码必须放在初始化web视图的地方，并且您需要为其他SDK版本创建另一个web视图类。
