Android2.2 API Chinese Document Series (1)-textview

 

Like the gadgets in a mechanical maze game-every widget is a useful tool in our hands. Due to time issues, you can learn its basic usage for the moment, however, you only need to learn it from the system at a time. At least you need to know that there is such an attribute and there is such a method, so that you can play a key role in some problems. Only by fully understanding it can you use it freely.
