检查设备通过亚行景观 [英] Check if device is landscape via ADB

问题描述

是否有可能通过ADB检查设备的方向？

Is it possible to check a devices orientation via ADB?

不受安装任何软件，调用任何现有的软件，只是通过亚洲开发银行。猜想有一个状态文件某处的/ proc ，但无法找到它。

Not by installing any software, calling any existing software, just through ADB. Would guess there is a status file somewhere in /proc, but could not find it yet.

推荐答案

这可以通过以下命令来完成：

This can be done through the following command:

adb shell dumpsys | grep 'SurfaceOrientation' | awk '{ print $2 }'

的输出将是一个整数范围从0到3为四个可能的方位。 0和2是风景而1和3是人像。由于 dumpsys 输出是非常大的，该命令可能需要几秒钟才能完成。

The output will be an integer ranging from 0 to 3 for each of the four possible orientations. 0 and 2 are landscapes while 1 and 3 are portraits. As the dumpsys output is very large, the command might take a few seconds to complete.

更新： dgmltn的修改可能要快得多：

Update: dgmltn's modification is likely much faster:

adb shell dumpsys input | grep 'SurfaceOrientation' | awk '{ print $2 }'
