android - 带选项卡的抽屉导航和工具栏

Question

伙计们，我的错误很简单。

我在 Android 应用程序上实现了一个类似于操作栏的自定义工具栏，并实现了一个抽屉导航。

问题是我使用的是 Material Design 主题，所以抽屉导航从屏幕顶部状态栏后面开始，占据所有屏幕高度，但如果我这样做，所有按钮和选项卡主要 Activity 变得无法理解，导致抽屉导航的高度为 7dp，操作栏为 4。我该如何解决？还有一个问题，如何让状态栏有点透明，让抽屉导航显示时背景变暗？

我想做这个效果，让我的标签可以点击:

How to make the status bar a little bit transparent and the make the background getting dark when show the navigation drawer?

半透明系统栏

You can now make the system bars partially translucent with new themes, Theme.Holo.NoActionBar.TranslucentDecor and Theme.Holo.Light.NoActionBar.TranslucentDecor. By enabling translucent system bars, your layout will fill the area behind the system bars, so you must also enable fitsSystemWindows for the portion of your layout that should not be covered by the system bars.

如果您要创建自定义主题，请将这些主题之一设置为父主题或包含 windowTranslucentNavigation和 windowTranslucentStatus主题中的样式属性。

顺便说一下，当抽屉显示时，我认为背景会显示为深色。此外，如果您使用本教程*(来自 - android4devs)*，它可以在之后向您显示深色抽屉正在展示。

• 使用:<android.support.v4.widget.DrawerLayout

希望这对您有所帮助。
