Android Studio 中的 XML 属性顺序

我面临的问题是如何在 Android Studio 中保持 XML 属性的正确顺序。正如您在下面看到的，style属性位于 layout_*属性之间，但是我希望它按名称排序(就像在 Eclipse 中一样)。我使用的是标准的 Intellij 代码格式化程序，Android Studio 允许用户设置自己的 XML 排序规则。设置位于 Code Style -> XML -> Arrangement，但它似乎不工作或我使用它错误。如何使用默认代码格式化程序按名称对 XML 属性进行排序？

android:layout_width="match_parent"
style="@style/BackgroundLight"
android:layout_height="wrap_content">

There is a plugin for IntelliJ which might do what you're after...

Finally got it.

  1. Choose File > Settings > Code Style > XML > Set from > Predefined Style > Android
  2. Set File > Settings > Editor > Formatting > Show "Reformat Code" dialog
  3. Run formatting on a XML file (CTRL+ALT+L by default)
  4. You will see a popup window, set the Rearrange entries flag
  5. Disable Reformat Code dialog in the settings

This way every XML file formatting will set the attributes in a proper order.

Edit: Starting with Android Studio 0.2.6 release the XML Android style formatting is set by default, but you still have to set the Rearrange Entries flag manually.

Automatically apply the Android XML code style if a code style hasn't already been customized. This will make it possible to automatically order XML attributes (check the "Rearrange Entries" checkbox in the "Code > Reformat Code..." dialog.)

To delete empty lines between them:

Preferences > Code Style > XML > Other > Keep blank lines: 0

And then just reformat your XML files.

File > Settings > Editor > XML > Arrangement Select Scheme and choose Default

UPDATE: the method I described below is an official way to fix this known issue, see: https://developer.android.com/studio/releases

After updating to the newest Android Studio v3.4.2 I found that it doesn't format XML code properly anymore. For instance, attributes ordering didn't work in layouts. It did indentation and namespaces ordering only.

I don't know the reason why it was broken after an update but was lucky to fix this:

  1. Go to Settings (CMD + , ) on Mac.
  2. Type format in Search box and click on Editor -> XML setting.
  3. Click on the Android tab and make the same settings here as it's on a picture:

Android tab in XML formatting Setting Settings on a picture quite normal, but of course you can tune this tab setting up to you.

  1. Go to the Arrangement tab and you will see something like this:

Arrangement tab in XML formattings Setting The reason why attributes are not getting sorted - sorting rules are empty.

  1. To fix this:

    1. Choose Scheme and play with Default IDE and Project options. Switching between them may help.
    2. Or choose Scheme which suites your needs and then click on Set from... blue text in right upper corner -> Predefined Style -> Android. You will see restored rules in the window:

Finally you will see restored rules here I also chose Force rearrange - Always

To save result – click Apply.

Also you can click on a gear icon near Scheme and copy settings or even restore defaults.

P.S. To me standard rules are comfortable, but it can be customized further. Here is an article which may help doing this: https://medium.com/@VeraKern/formatting-xml-layout-files-for-android-47aec62722fc
