Question

我使用WebView创建应用程序来加载一个描述DHTML网格的JSP页面。我的问题是当我们在Web视图中滚动此网格大约100行我的应用程序挂起，内存上升并显示ANR报告，但如果我们滚动20到30行它工作正常。请建议我，我们做错了什么。这是JSP错误或我的应用程序错误。

  web_view = (WebView) findViewById(R.id.web_view);
        WebSettings settings = web_view.getSettings();
        settings.setJavaScriptEnabled(true);
        settings.setDomStorageEnabled(true);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            if (0 != (getApplicationInfo().flags & ApplicationInfo.FLAG_DEBUGGABLE))
            { WebView.setWebContentsDebuggingEnabled(true); }
        }
        web_view.setWebViewClient(new WebViewClient() {
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }

            public void onPageFinished(WebView view, String url) {

            }

            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

            }
        });

        web_view.loadUrl("http://192.168.x.xyz:1212/grid.jsp?");

以下是在log cat中打印的错误
