webview

In this article , I will focus on the WebView approach .

本文我将重点介绍WebView方法。

The WebView is a fairly complex class that can be highly customized .

WebView是一个相当复杂的类，可高度定制。

The method creates the appropriate WebView dialog .

该方法创建适当的WebView对话框。

In this way , the Java code can execute JavaScript code defined in the WebView .

这样，Java代码就可以执行WebView中定义的JavaScript代码了。

For the purposes of this application , the WebView control is somewhat minimally deployed .

对于此应用程序的目的来说，WebView控件已经进行了最低限度的部署。

To cause the WebView control to navigate to a page , you have a couple of different options .

要导致WebView控件导航到一个页面，可以采用几种不同的方式。

For a somewhat more complex example , you are encouraged to walk through the code sequence when the Dynamic button is selected in the WebView .

对于一个稍微复杂一点的例子，鼓励您好好看一下Dynamic按钮在WebView中被选中时的代码段。

You will revisit the Button setup code later in this article ; for now focus on the setup of the WebView control or widget .

本文稍后还会详细介绍Button设置代码，现在将重点放在WebView控件或小部件的设置上。

Note that if the single sign-on method is not defined or the native Facebook application is not present , the SDK will default to the WebView approach for authentication / login .

注意，如果没有定义单点登录方法，或者没有给出原生Facebook应用程序，那么SDK将默认对身份认证/登录使用WebView方法。

For example , the WebView contains an id of calculator ; however , the TextView does not contain an id as its value is not changed throughout the lifetime of the application .

例如，WebView包含calculator的一个id；但是TextView不包含id，因为它的值在应用程序的整个生命期内是不变的。

The SDK provides two methods to authenticate , one that is referred to as single-sign on which uses , if installed , the native Facebook application dialogs , and the default WebView approach to dialogs .

SDK提供两种方法进行身份认证，一种称之为单点登录，如果安装了的话，它使用原生的Facebook应用程序对话框，另一种是默认的WebView方法。
