如何在 Android Studio (2.1.1) 中关闭 Java 中的自动缩进?(Windows 7的)

如果我有一行包含 8 个空格(是的，空格，而不是制表符)和一些文本...

If I have a line with 8 spaces (yes, spaces, not tabs) and some text...

        x=3;

... 并且我的光标位于分号之后，当我按下 Enter 键时，它会将光标定位在 x 下方.换句话说，它缩进了 8 个位置.如果我然后按退格键，它会将光标定位在分号之后！我希望退格键能让我在新行中返回 1 个空格.

... and my cursor is placed after the semicolon, when I hit Enter it positions the cursor under the x. In other words it indents it 8 positions. If I then hit backspace it positions the cursor after the semicolon! I expect the backspace to take me back 1 space on the new line.

在Editor>Code Style > Java中，Tab size = 1，Indent = 0，Continuation indent = 0.注意如果我尝试将 Tab 大小设置为 0，则下次我打开该对话框时为 1，因此 Android Studio 显然不能接受 0，即使我在几个 S.O.问题.

In Editor>Code Style > Java, Tab size = 1, Indent = 0, Continuation indent = 0. N.B. that if I try to set Tab size to 0 it's 1 next time I bring up that dialog, so 0 is apparently not acceptable to Android Studio, even though I see it suggested in several S.O. questions.

在编辑器>代码样式中，我取消选中检测并使用现有文件缩进进行编辑，现在如果我在分号后用光标按 Enter 键，它会将光标定位 4 个空格从右边开始，换句话说，它仍然缩进，只是没有那么多.

In Editor > Code Style I UNchecked Detect and use existing file indents for editing and now if I hit Enter with the cursor after the semicolon it positions the cursor 4 spaces in the from the right, in other words it still indents, just not as much.

注意，在进行这些设置后，我做了一个文件 > 使缓存无效/重新启动.

N.B, that after making these settings I did a File > Invalidate Caches / Restart.

我不想要任何自动缩进.当我按 Enter 时，我希望它将光标定位在新行的第一个位置，当我按退格键时，我希望它返回 1 个位置，就像一个普通的愚蠢"编辑器.如何关闭 Android Studio 中的所有自动缩进?

I don't want any automatic indenting. When I hit Enter I want it to position the cursor at the first position of the new line, and when I hit backspace I want it to go back 1 position, just like an ordinary "dumb" editor. How do I turn off all automatic indenting in Android Studio?
