Question

I have some problem in my web view.
I want to load a string from a WordPress blog, witch have html tags such as <a> and image tag and ... .
So my problems are:

As I mention above, I want to load a local string and I want to handle user click on the links, so I load data like this into the web view:

WebView webview = (WebView) this.findViewById(R.id.mainWV);
webview.setWebViewClient(new MyWebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setDomStorageEnabled(true);

String s="<p>It will<a href=\"http://www.bbc.com/\"> enable</a> Seattle-based Alaska to expand into lucrative hubs such</p>\n<p><img class=\"aligncenter size-full wp-image-1035\" src=\"http://ichef.bbci.co.uk/news/660/cpsprodpb/D09F/production/_89070435_89069565.jpg\" alt=\"\" width=\"300\" height=\"120\" /></p>\n<p>as San Francisco and Los Angeles.</p>\n"; 

webview.loadDataWithBaseURL("", s, "text/html", "utf-8", "");

and another way I tried was:

 String head1 = "<head></head>";
    String text = "<html>" + head1
            + "<body  dir=\"rtl\" >" + s
            + "</body></html>";

webview.loadData(text, "text/html", "utf-8");

and my client is :

 class MyWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        Log.d("USER_CLICKED", url + "USER_CLICKED");
        return true;
    }
}

Ok, now when I run the app, and when I click on <a> I never see 'USER_CLICKED', but the webview content change and it seems web view is empty, I mean is white as snow.
notice 1: when I try this:

webview.loadUrl("https://android-arsenal.com/");

and run the app, when I click on the links in the loaded web view, every thing is OK, and i see this Log: 'USER_CLICKED' and the related URL. notice 2: yes i try a lots of different URL, but loading from string, nothings change in click handling.
notice 3: I test in android 5.1 and 4.1 in 4.1 clicked recognized and is see 'User.. but in the 5.1 the white page story happens.(Edit: android 6 also do not show 'USER... ')

my number 2 problem is, when I call this:
```
 webview.loadDataWithBaseURL("", s, "text/html", "utf-8", "");
```
the image tag does not load! I mean it is just ignore to load the images, and I do not know why.
notice 3: when I copy text from inside the web view there is some rectangle in the text.

Answer 1

确定每一个，经过很长一段时间，我发现问题，所以正如我上面提到的，我从WordPress rest API（json）中取出字符串，所以在我看来，字符串应该没问题，但是我发现了，字符串中有一些额外的'\'，字符串如下：

<p>It will<a href=\\\"example URL\\\"> enable</a> Seattle....

，简单就是我只是使用： S = s.replaceAll（ “\\”， “”）; 所以，感谢任何看过这篇文章的人。

Answer 2

网址是一个网址。第一项是HTML，而不是URL。如果要加载URL，则必须传递有效的URL（而不是HTML），并且不要期望从正在加载的HTML字符串中神奇地解析URL。事实上，第一项甚至不是有效的HTML，它是HTML的一部分，可能是一个片段，但它甚至没有包含在我希望Web视图需要的HTML标记中。
