Question

我正在构建我自己的Android应用程序，当我把它放在我的Nexus 5和Xperia Neo上工作正常，但在Nexus 4或Galaxy S3上运行缓慢。我不知道它发生了什么。你可以帮帮我吗？我正在使用android：minSdkVersion =“14”和android：targetSdkVersion =“17”，Fragments和一个DrawerLayout。

好的，我发现了错误。随着Lint警告，我正在透支我的背景。但我不知道如何解决它。我改变了这个：

 <style name="AppBaseTheme" parent="android:Theme.Holo">
 </style>

到此：

<style name="AppBaseTheme" parent="android:Theme.Holo">
 <item name="android:windowContentOverlay">@null</item>
 <item name="android:windowBackground">@null</item>
</style>

现在我可以将每个layout.xml放在我的背景上。但我的问题是，在我改变之前，我的按钮看起来像一个“真正的按钮”，但现在新的更改看起来像没有边框的TextView。

我的新Android应用程序速度慢
