Number picker Rendering

[paulbalomiri]

This is an aggegate for several minor issues:

• The number pickers in the Options section of the screen (below widgets) shows a white intransparent background on first load. This background disappears upon any touch of the number pickers' handles (+ or -) and only seems to appear if the option is not initialized as a checkbox
• The Number pickers in the Options section change in height when transitioning between checkbox and numbered style.
  • Also the font changes away from the default font.
  • The text inside the Number picker should never (exept for sg./plural changes) change it's appearance or position.
  • The number picker does not make a clicking sound when pressed while being in chackbox state
  • When pressing a number picker the visible overlay effect should be over the whole element at all times (any state) when changing values.

    Visibility/enabling rules for numberpicker in checkbox state ( set_zero_checked = true)

    1. checkbox unchecked: value = 0 and set_zero_checked = True
    2. checkbox checked: value = 1 and set_zero_checked = True si max_value = 1
    3. checkbox unchecked: visible as in 1. if value = max_value=0, but DISABLED
    4. checkbox checked visible as in 2) if value = min_value=max_value=1, but DISABLED

In states 3 and 4 the checkbox shall be visible but not enabled, thus yielding no visible or audible effects

Conditions for resolving this issue:

• [ ] The background of numberpickers is always the same and never has an intransparent background (only appears in Oprions section)
• [ ] No change in Numberpicker overall position, height or width upon pressing interaction with it.
• [ ] No change in the Number pickers' text position inside the number picker upon changing the number picker state (Exception: changing the label text for singular and plural forms
• [ ] Audible click can be heared when a user touches an enabled handle on the numberpicker
• [ ] Change the visible overlay effect on the numberpicker when making a change such that it consistently (= in any state) will show as an overlay over the whole number picker widget

The actual issue with the audible click seems to be related to the fact that the OS Provider UI Elements used are of button class for the number picker's + and -, and of checkbox type for the checkbox.

Using another Button subclass might make the behaviour consitent for the audible touch behaviour.

Don't start playing around with sounds, just try fo find another subclass that behaves under most Android OS in the same manner as the + and - buttons
