android - How to get button width after it's layout visibility is changed from gone to visible -


have linearlayout few buttons in it.

initially visibility set view.gone after user clicks, visibility set visible

this need programmatically detect 1 of button's width , match other button width it.

initial call 

public void onwindowfocuschanged(boolean hasfocus)

does not work since layout not visible.

getmeasuredwdith() , getwidth()

return 0 when called after visibility flags has been changed.

any ideas get width of button?

figured out.

ended going xml.

  1. each row of buttons got own linearlayout.
  2. wrapped button rows in parent linearlayout.
  3. set parent , leading button (to i'll matching widths of other buttons) layout_width "wrap_content"
  4. set other button rows' layout_widths 'fill_parent'

done.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
