adb command to open settings and change them

Question

I'm looking for adb command to open settings and change them. For example: this command open display settings

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

I want to go further in menu to Display output mode then choose 720P 60HZ

As my menu is like this on android tv box:

Settings > Display > Display output Mode > HDMI 720P60HZ etc

Is there a adb command to do this go through settings then choose 720P60Hz directly with shell ?

Answer 1

Use this command to see a help on how you can use the settings adb shell command:

adb shell settings

Use get and put commands (after settings) to change the settings.

You will have to figure out the KEYs (use list) and acceptable VALUEs yourself (read documentation like https://developer.android.com/reference/android/provider/Settings.Global for the global NAMESPACE).

Answer 2

As far as I know ther is no such functionality. However, you can use the

adb shell input tap <x> <y>

command to trigger a touch event. Unfortunately, such code will not work device-indepently as the position of your settings on the screen depends on the device you are using.

Alternatively you can try the

adb shell input keyevent <19|20|21|22>

command to emulate curser events to select the setting you want to alter.

Finally, you can use

adb shell input keyevent 66

to trigger the enter key. This should work on all devices having the same options in the settings submenu.

I'm not sure how to change the value directly, but to expand on another answer (and also because it sounds like this is what you're asking for), you can use adb to navigate through settings windows and pick different things in the UI. I've done that with some settings I can't seem to set a value from a single adb command. I just use the virtual Tab key to navigate through the menu items then press Enter to select a submenu or toggle an option.

I don't have an android tv box so I don't have the setting you do, but the commands would look something like this:

adb shell am start -a android.settings.DISPLAY_SETTINGS
adb shell input keyevent TAB
adb shell input keyevent TAB
adb shell input keyevent ENTER
adb shell input keyevent TAB
adb shell input keyevent TAB
adb shell input keyevent TAB
adb shell input keyevent TAB
adb shell input keyevent ENTER
adb shell am force-stop com.android.settings

You can try sending one tab command at a time to see how many you need to send before getting to the item you want.

Tips:

You can also use the Back button to go back a page:

adb shell input keyevent BACK

And you can use the arrow keys to navigate through confirmation popups (or move brightness/volume sliders):

adb shell input keyevent DPAD_RIGHT
adb shell input keyevent DPAD_LEFT
adb shell input keyevent DPAD_UP
adb shell input keyevent DPAD_DOWN

Here's a list of more key commands you can use (just look for the ones preceded by KEYCODE_, and remove that part. e.g. KEYCODE_BACK would be BACK as illustrated above):

And here's a list of more direct settings windows you can launch:
