Difference between Android Framework widgets and their AppCompat version

问题

I have lately noticed that there are AppCompat versions of most View types in Android, for example ListView / ListViewCompat, Button / AppCompatButton etc.

For these more simple Views (not counting for example SwitchCompat), what are the difference between them and the Android Framework version? I have not found any documentation on this matter...

I'm interested in knowing the consequences of choosing either version and if there are any advantages in chosing one over the other.

Specifically:

Difference between ListView and ListViewCompat
Difference between Button / AppCompatButton
Difference between ImageView / AppCompatImageView
Difference between EditText / AppCompatEditText
Difference between TextView / AppCompatTextView

I changed from normal to AppCompat versions with the expectation that colors would be used from the theme and look the same on Lollipop and pre-lollipop, but it rather had the opposite effect on some views (such as ListView)

回答1:

AppCompat is support older version of android os like AppCompat-v7 is support from android 6.1.1 to android 2.6.0

for above reason they have created AppCompat classes of below widgets in this support library nothing more.

from Documentation
