Have just begun styling and theming an app.
I have many EditTexts in TextInputLayouts in an AppCompatActivity. 
My questions are:
- Not sure what the line (the blue line above) in the EditTextwidget is called, just referring it as 'ruler'. How can the rulers (invisible above), be made visible, and in any custom color. Presently, the ruler shows only on tapping theEditText.
- The EditTextcursor does not show, how can it be made visible?
- How can the button 'Add' above be customized regarding its background color and text color?
- How can the focus be set to the first EditTextinitially?
- How can the TextInputLayout's hint color be changed after it shrinks and flies to the top? (Presently, blue.)
- Is the default Android font Roboto? How can I change the font to anything that's available out there, 'real quick'?
Greatly appreciate any help or pointers.
