我面临着一个奇怪的问题。
在我的应用程序,我需要的基础上,从资产的文件夹中的WebView点击按钮加载一个静态的HTML文件。
现在在5个HTML文件,一个HTML文件包含15静态链接。这些链接需要重定向用户到所提到的网址在手机浏览器。我已经使用目标=_空白
为目的,遵循我的HTML文件。
< DIV CLASS =盖子>< A HREF =https://www.irctc.co.in/目标=_空白>铁路预订< / A>< / DIV>
现在,这个工作正常,在一个简单的的WebView一个示例应用程序
无任何 WebViewClient
添加到它。
但我需要一个 WebViewClient
我的其他功能。所以在那个时候 目标=_空白
是完全忽略。并且URL是在一个web视图本身打开。
我找到了一个解决办法,我可以使用 shouldOverrideUrlLoading
如下:
myWebView.setWebViewClient(新WebViewClient(){
公共布尔shouldOverrideUrlLoading(web视图查看,字符串URL){
// TODO自动生成方法存根
如果(url.equalsIgnoreCase(https://www.irctc.co.in/))
{
view.getContext()。startActivity(
新的意图(Intent.ACTION_VIEW,Uri.parse(URL)));
返回true;
}
其他
返回super.shouldOverrideUrlLoading(查看,网址);
}
});
因此,这是开放的特定的URL在默认浏览器。
所以基本上我的问题是:
为什么目标=_空白
忽略,而我们使用 WebViewClient
?而且还有没有其他的解决此问题?因为我有15个链接,我需要比较。我无法加载所有URL在新的浏览器,因为有几个环节,这就需要在同一个web视图中打开了。
我有一个想法,一个解决方法。更换应在新窗口中打开一个自定义模式中的所有环节。然后你就可以处理你自己的。
对于一个最小的中断也设置一个自定义主题,并处理所有配置更改:
<活动机器人:名称=com.example.LinkHandler
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
机器人:主题=@安卓风格/ Theme.Translucent>
<意向滤光器>
<作用机器人:名称=android.intent.action.VIEW/>
<类机器人:名称=android.intent.category.DEFAULT/>
<类机器人:名称=android.intent.category.BROWSABLE/>
<数据机器人:计划=your.link.handler.schema/>
&所述; /意图滤光器>
< /活性GT;
然后在您的链路处理器可以使用 getIntent()读取URL。的getData()
。
也请记住,你应该处理HTTP和HTTPS,我跳,在我短暂例如上面。
下面是一个JavaScript示例如何重写的网址:
的(VAR I = 0; I< document.links.length;我++) {
如果(document.links [I] .TARGET ==_blank){
document.links [I] .href =。your.schema.for+ document.links [I] .href;
}
}
< UL>
<李>< A HREF =http://example.com>试验1< / A>< /李>
<李>< A HREF =http://example.net目标=_空白>测试2版; / A>< /李>
<李>< A HREF =https://example.com目标=_空白>测试第3版; / A>< /李>
<李>< A HREF =https://example.net>测试4℃; / A>< /李>

I am facing a strange issue.
In my application, I need to load a static html file based on clicked button in a WebView from assets folder.
Now among 5 html files, one html file contains 15 static links. These links need to redirect user to the mentioned url in a mobile browser. I have used target="_blank"
for that purpose as follows in my html file.
<div class="lid"><a href="https://www.irctc.co.in/" target="_blank">Railway Reservation </a></div>
Now, this works fine in a sample application with a simple WebView
without any WebViewClient
added to it.
But I need a WebViewClient
for my other functionalities. So at that time target="_blank"
is totally ignored. And the url is opened in a WebView itself.
I found a workaround, that I can use shouldOverrideUrlLoading
as follows:
myWebView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
if(url.equalsIgnoreCase("https://www.irctc.co.in/"))
{
view.getContext().startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
return true;
}
else
return super.shouldOverrideUrlLoading(view, url);
}
});
So this is opening that particular url in a default browser.
So basically my questions are:
Why is target="_blank"
ignored while we use WebViewClient
? And is there any other workaround for this issue? Because I have 15 links, which I would need to compare. I can't load all urls in a new browser, as there are a few links, which need to be opened in a same WebView, too.
I have an idea for a workaround. Replace all links which should been opened in a new window with a custom schema. Then you can handle that by your own.
For a minimal interruption set also a custom theme and handle all configuration changes:
<activity android:name="com.example.LinkHandler"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
android:theme="@android:style/Theme.Translucent">
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
<data android:scheme="your.link.handler.schema"/>
</intent-filter>
</activity>
Then in your link handler you can read the url by using getIntent().getData()
.
Please also keep in mind that you should handle http and https, I skipped that in my short example above.
Here is an JavaScript example how to rewrite the urls:
for(var i=0; i<document.links.length; i++) {
if(document.links[i].target == "_blank") {
document.links[i].href = "your.schema.for."+document.links[i].href;
}
}
<ul>
<li><a href="http://example.com">Test 1</a></li>
<li><a href="http://example.net" target="_blank">Test 2</a></li>
<li><a href="https://example.com" target="_blank">Test 3</a></li>
<li><a href="https://example.net">Test 4</a></li>
</ul>
