Hi,
I open my app (developed by AppDesigner), I want it startup and auto go to (activate) one edit-field compoenent, no need to click it, so I could immediately type something.
Thanks!

Please refer to the below answer for a temporary workaround
In order to make it working with respect to R2021b, change the startup function to the below code, by adding a pause between the declaration of the Robot and key press function call. Adding another pause between the key press and key release would let you type into the field during the corresponding interval.
import java.awt.*;
import java.awt.event.*;
rob = Robot;
pause(1)
rob.keyPress(KeyEvent.VK_TAB)
pause(10) %duration for which the edit field is enabled
rob.keyRelease(KeyEvent.VK_TAB)
rob.keyPress(KeyEvent.VK_TAB)
rob.keyRelease(KeyEvent.VK_TAB)
