Adb shell command can i use to open language settings directly?

Issue

I have found that in order to change the language on a device using an adb shell command requires the device to be rooted. Since this is something I don't want to do, I am looking for an adb shell command that opens up the language settings of a device, comparable to:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings

Comparable, is there any database that I can use to find out more about these adb commands?

Thanks in advance!

Solution

For newer devices (3.0 and above) that use fragments, use:

adb shell am start -n com.android.settings/.Settings -e :android:show_fragment com.android.settings.LocalePicker

For older devices (2.3 and below) that don't use fragments, use:

adb shell am start -n com.android.settings/.LocalePicker

Also, for a reference you can just type adb into your terminal and it will display a list of commands that ADB supports. For the am command specifically, you can type adb shell am and it will display a list of options. In most cases if you do not specify any options for an ADB command, it will display help information for that command.
