Android -- ProgressBar(进度条的使用)

我们在开发程序是经常会需要软件全屏显示、自定义标题（使用按钮等控件）和其他的需求，今天这一讲就是如何控制Android应用程序的窗体显示.

　　requestWindowFeature可以设置的值有：（具体参考 点击链接查看效果）
 　　　  1.DEFAULT_FEATURES：系统默认状态，一般不需要指定
        // 2.FEATURE_CONTEXT_MENU：启用ContextMenu，默认该项已启用，一般无需指定
        // 3.FEATURE_CUSTOM_TITLE：自定义标题。当需要自定义标题时必须指定。如：标题是一个按钮时
        // 4.FEATURE_INDETERMINATE_PROGRESS：不确定的进度    圆形的进度条
        // 5.FEATURE_LEFT_ICON：标题栏左侧的图标
        // 6.FEATURE_NO_TITLE：无标题
        // 7.FEATURE_OPTIONS_PANEL：启用“选项面板”功能，默认已启用。
        // 8.FEATURE_PROGRESS：进度指示器功能
        // 9.FEATURE_RIGHT_ICON:标题栏右侧的图标
