Android中的自定义小部件

Question

I need to customize my Android application for ancient people, which typically have vision problems.

If is not so difficult increase the font size of EditText or TextView fields, I can't say the same about the TimePicker , DatePicker or NumberPicker . For these widget I think that I can't change the size. Right?

Someone knows how can I solve this problem? I need to create a custom plugin? If so, where I can found materials for this purpose?

Answer 1

What you want is call "Custom Widget" or "Custom View"
