basic4android - 减少按钮 statelistdrawablecode

Question

我的项目中有几次这段代码运行良好，但想知道最简单的方法是允许它用于多个按钮而不重复代码。例如 - 我在下面有 mybuttonBTN1 并想添加 mybuttonBTN2 等。 - 我尝试了几种方法，但总是得到奇怪的结果。

Dim buttonSLD As StateListDrawable
buttonSLD.Initialize
Dim buttonSTS(2) As Int
buttonSTS(0) = buttonSLD.State_Enabled
buttonSTS(1) = -buttonSLD.State_Pressed
buttonSLD.AddState2(buttonSTS, buttonENL)
Dim buttonSTS(1) As Int
buttonSTS(0) = bbuttonSLD.State_Pressed
buttonSLD.AddState2(bbuttonSTS, buttonPRS)
mybuttonBTN1.Background = buttonSLD

Answer 1

就像是：

Sub SetStateDrawable (Btn As Button, Pressed As Drawable, Enabled As Drawable)
 Dim buttonSLD As StateListDrawable
 buttonSLD.Initialize
 Dim buttonSTS(2) As Int
 buttonSTS(0) = buttonSLD.State_Enabled
 buttonSTS(1) = -buttonSLD.State_Pressed
 buttonSLD.AddState2(buttonSTS, Pressed)
 Dim buttonSTS(1) As Int
 buttonSTS(0) = bbuttonSLD.State_Pressed
 buttonSLD.AddState2(bbuttonSTS, Enabled)
 Btn.Background = buttonSLD
End Sub

 SetStateDrawable(myButtonBTN1, buttonPRS, buttonENL)
