Setting Holo theme for Android application
提问by Derek Organ
I have a simple login screen with username and password.
我有一个带有用户名和密码的简单登录屏幕。
I'd like it to show the EditTextfields in the same way as you see in the Holo theme on Ice Cream Sandwich and Honeycomb.
我希望它以EditText与您在 Ice Cream Sandwich and Honeycomb 的 Holo 主题中看到的相同的方式显示字段。
In my manifest file I have
在我的清单文件中，我有
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@android:style/Theme.Holo">
Shouldn't the text fields now look different e.g. have no top, left and right borders?
文本字段现在看起来不应该有所不同，例如没有顶部、左侧和右侧边框吗？
Mine seem to look the exact same. I'm sure I'm doing something very basically wrong but any suggestions welcome.
我的似乎看起来完全一样。我确定我做的事情基本上是错误的，但欢迎提出任何建议。
This is what I see in the emulator:
这是我在模拟器中看到的：

The original Android Holo Theme is just for API Level 11+. But there is an open source project called HoloEverywhere.
原始的 Android Holo 主题仅适用于 API 级别 11+。但是有一个名为 HoloEverywhere 的开源项目。
Take a look at this. This should solve your Problems.
看看这个。这应该可以解决您的问题。
So if you refere it as an Library you can set your Theme like this:
因此，如果您将其称为库，则可以像这样设置主题：
android:theme=“@style/Theme.Holo
// or if you want to use the Holo light theme:
android:theme=“@style/Theme.Holo.Light
回答by The Holo Dev
Try doing it on a per-activity basis. That's how I've always done it. It looks to me like the theme is not taking effect at all in your screenshot. Theme.Holo is dark. The white theme is Theme.Holo.Light.
尝试在每个活动的基础上进行。我一直都是这样做的。在我看来，您的屏幕截图中的主题根本没有生效。Theme.Holo 是黑暗的。白色主题是 Theme.Holo.Light。
<activity
android:name=".login"
android:label="@string/login"
android:noHistory="true"
android:theme="@android:style/Theme.Holo.Light"/>
<activity
android:name=".Preferences"
android:theme="@android:style/Theme.Holo.Light" >
etc rather than in the app level
等而不是在应用程序级别
Also, to correct Ahmad, Holo is available from Honeycomb and on, or 11+.
此外，为了更正 Ahmad，Holo 可从 Honeycomb 和 11+ 获得。
回答by Aleq
Actually, Holo is available since API 11; it's just Theme.Holo.Light.DarkActionBarthat came in API level 14. There is no need for 15+.
实际上，Holo 从 API 11 开始就可用了；只是Theme.Holo.Light.DarkActionBarAPI 级别为 14。不需要 15+。
For older API Levels, HoloEverywhere, ActionBarSherlock, ViewPageIndicatorand such are neccessary, as mentioned by Ahmad as well.
对于较旧的 API 级别，HoloEverywhere、ActionBarSherlock、ViewPageIndicator等是必要的，正如 Ahmad 所提到的。
