TextView 中的 paddingBottom 和 paddingEnd 有什么区别？

Question

I understand the difference between padding and margin, but I don't understand the difference between those two pairs of attributes: bottom and end and on the other hand start and top. Documentation

Answer 1

It's pretty clear: your TextView has a bound and padding is distance from the bound to the context (where text is rendered)

In the picture, padding is green area.

• paddingTop is upper distance
• paddingBottom is down distance
• paddingStart is right distance if rtl is enabled, otherwise it's left distance
• paddingEnd is left distance if rtl is enabled, otherwise it's right distance
