Quickly build a selector tool class with Code Selectorhepler

Selectorhepler Tool Class

Generally need to click on the effect or selected, the focus of the state change after the change effect, you need to create a new XML file under the Drawable folder, and then write a selector. Relatively troublesome, so I wrote a quick code to build a Selector tool class.

Selectorhepler Code:

How to use:

Colorstatelist color = Selectorhepler. getinstance(). Getpressedselectorcolor(Color. White, Color. BLUE);Statelistdrawable drawable = Selectorhepler. getinstance(). Getpressedselectordrawable(This, R. drawable. IC_normal, R. drawable. IC_pressed);Tv. SetTextColor(color);Tv. Setbackgrounddrawable(drawable);
