Universal adapter (2) Extract CommonAdapter

The data and methods in the BaseAdapter are basically the same

getCount(), getItemId(), getItem() 

The main thing is that the getView implementation is different,

Common methods will be extracted

Take a look at the simplified MagicAdapter

(1) Inherit custom CommonAdapter

(2) The main implementation of control assignment method convert(); \
