工具栏隐藏在特定的webview URL上无效

Question

我有一个ID为“toolbar_footer”的工具栏。如何为特定网址隐藏此工具栏，例如：'index.php'。我的项目主要活动的部分在下面给出了我已经尝试了很多次并且无法使其与给定的答案一起正常工作，因此使用xml布局代码更新代码。

请帮忙..我这个问题持续数月了

private class UriWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            String host = Uri.parse(url).getHost();

            urlData = url;


            if (target_url_prefix.equals(host)) {
                if(url.contains("index.php") || url.contains("login.php") || url.contains("register.php"))          {
                    System.out.println("This is my target url 2");
                    System.out.println(url);
                    //showToolBar = false;
                    findViewById(R.id.toolbar_footer).setVisibility(View.GONE);
                }
                else
                {
                    findViewById(R.id.toolbar_footer).setVisibility(View.VISIBLE);
                }
                if (mWebviewPop != null) {
                    mWebviewPop.setVisibility(View.GONE);
                    mContainer.removeView(mWebviewPop);
                    mWebviewPop = null;
                }

                return false;

            }

            boolean result = UrlHander.checkUrl(MainActivity.this, url);
            if (result) {
                ProgressDialogHelper.dismissProgress();
            } else {
                currentUrl = url;

                if (!show_content) {
                    if(url.contains("index.php") || url.contains("login.php") || url.contains("register.php"))          {
                        System.out.println("This is my target url 2");
                        System.out.println(url);
                        //showToolBar = false;
                        findViewById(R.id.toolbar_footer).setVisibility(View.GONE);
                        findViewById(R.id.fab).setVisibility(View.GONE);
                    }
                    else
                    {
                        findViewById(R.id.toolbar_footer).setVisibility(View.VISIBLE);
                        findViewById(R.id.fab).setVisibility(View.VISIBLE);
                    }

                    ProgressDialogHelper.showProgress(MainActivity.this);
                }
            }
            return result;
        }


        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
            if (!NetworkHandler.isNetworkAvailable(view.getContext())) {
                view.loadUrl("file:///android_asset/NoInternet.html");

            }
            hideStatusBar();
            ProgressDialogHelper.dismissProgress();
        }

        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            super.onReceivedError(view, errorCode, description, failingUrl);
            if (!NetworkHandler.isNetworkAvailable(view.getContext())) {
                view.loadUrl("file:///android_asset/NoInternet.html");
            }
            hideStatusBar();
            ProgressDialogHelper.dismissProgress();
        }

        @Override

            super.onReceivedHttpError(view, request, errorResponse);

                view.loadUrl("file:///android_asset/NoInternet.html");
            }
            hideStatusBar();
            ProgressDialogHelper.dismissProgress();
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            if(url.contains("index.php") || url.contains("login.php") || url.contains("register.php"))          {
                System.out.println("This is my target url 2");
                System.out.println(url);
                //showToolBar = false;
                findViewById(R.id.toolbar_footer).setVisibility(View.GONE);
                findViewById(R.id.fab).setVisibility(View.GONE);
            }
            else
            {
                findViewById(R.id.toolbar_footer).setVisibility(View.VISIBLE);
                findViewById(R.id.fab).setVisibility(View.VISIBLE);
            }

        }

Answer 1

隐藏工具栏你必须把这条线。 getSupportActionBar().hide();

因此，首先检查是否有网址然后将此行放入if block

if(url.contains(“your text”){
getSupportActionBar().hide();
}
