fixed size , and demand is inconsistent.
requirements are as follows :
1. TextView size , along with the text how much it will change its size , can not be fixed . Ie, text and more , View it bigger .
2. while the background image, and the TextView can always maintain the same size , that image size, size of the decision by the TextView , rather than by the picture decision.
