Make dialogs focusable to support automation testing

[saggywaggy2012]

Context:

• Some automation testing framework like Appium and Selenuim uses Android UI Automator Viewer tool to capture and process view hierarchy data.
• Android UI Automator Viewer can only capture view hierarchy from focusable windows.
• Our DateAndTimePickerDialogs are added to window with FLAG_NOT_FOCUSABLE flag. Due to this all DateAndTimePickerDialogs are not focusable and so Android UI Automator Viewer not able to capture them in a view hierarchy.
• Such dialogs are not accessible from automation testing frameworks like Appium and Selenuim.

Changes Details:

• To make DateAndTimePickerDialog views accessible from UI Automator Viewer, need to make the dialogs focusable.
• Added support to make DateAndTimePickerDialog focusable by using below ways:
  • SingleDateAndTimePickerDialog.Builder#focusable()
  • SingleDateAndTimePickerDialog#setFocusable(boolean)
  • DoubleDateAndTimePickerDialog.Builder#focusable()
  • DoubleDateAndTimePickerDialog#setFocusable(boolean)
