Java 与浏览器相比，Android Web View速度非常慢且响应速度不快，为什么？,java,android,android-webview,Java,Android,Android Webview,我在stack overflow中尝试了类似问题的答案，但没有成功，所以请告诉我我的代码有什么问题，我需要添加什么 在我的android代码中，我包含了以下内容： webView = (WebView) findViewById(R.id.webviews); webView.setWebViewClient(new MyBrowser()); webView.getSettings().setRenderPriority(WebSettings.

我在stack overflow中尝试了类似问题的答案，但没有成功，所以请告诉我我的代码有什么问题，我需要添加什么

在我的android代码中，我包含了以下内容：

        webView = (WebView) findViewById(R.id.webviews);
        webView.setWebViewClient(new MyBrowser());
        webView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
        webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
        webView.getSettings().setLoadsImagesAutomatically(true);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
        webView.getSettings().setDomStorageEnabled(true);
然后呢,

connect.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                connect.setVisibility(View.INVISIBLE);
                editText.setVisibility(View.INVISIBLE);
                uunnamed.setVisibility(View.VISIBLE);
                tv.setVisibility(View.INVISIBLE);

                webView.setVisibility(View.VISIBLE);

                webView.loadUrl("http://192.168.1.8:8081");


            }
        });
和我的webclient类：

private class MyBrowser extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}
问题是什么？为什么它在web视图中速度慢，而在chrome浏览器中速度快？

我不是基于web技术的应用程序的专家，但我的团队是

根据她的代码（）尝试以下设置：

webView.setInitialScale(0);
webView.setVerticalScrollBarEnabled(false);
// Enable JavaScript
final WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setJavaScriptCanOpenWindowsAutomatically(true);
settings.setLayoutAlgorithm(LayoutAlgorithm.NORMAL);

// Enable AppCache
// Fix for CB-2282
settings.setAppCacheMaxSize(5 * 1048576);
settings.setAppCachePath(databasePath);
settings.setAppCacheEnabled(true);
