在android studio中找不到“Theme.Material”

Question

When I create a new Project in Android Studio, the dafault app theme is "Theme.appCompat.light". Whene I try to set "Theme.Material" as theme in the manifest Android Studio shows me no suggestion, and finds no "Theme.Material". I updated everything in the sdk manager. What have I to do to use Material Theme?

Answer 1

To be able to use all of Theme.Material you should:

1. Make sure compileSdkVersion is set to at least 21.
2. Make sure that in your dependencies you have compile 'com.android.support:design:24.0.0'

Both of these can be found on your build.gradle (Module: app) file.

After that you can apply Material Theme simply by going to your AndroidManifest.xml file and inside <application> tag make sure you have a line that says android:theme="@android:style/Theme.Material.Light" .

Answer 2

It won't show up if you just use @style/Theme.Material like with how you'd normally use @style/Theme.AppCompat .

Theme.Material requires you to use @android:style/Theme.Material .

Answer 3

您在android闭包中的compileSdkVersion需要为 21 或更高才能引用Theme.Material 。

Answer 4

此外，如果 AS 编辑器中的 API 版本低于 21，则在尝试更改特定布局的主题时弹出的选择主题窗口中，材质深色和浅色主题部分将为空。
