Android自定义视图'；滚动时填充

我编写了一个自定义文本视图（实际上是什么类型的视图并不重要），它扩展自

视图

。我在XML文档中向该视图添加了填充，并读取这些填充，然后将其传递给

super

，以应用这些填充。在我的

onDraw

和

onMeasure

中，我也考虑了这些填充，一切正常

除了，如果我通过方法

view.scrollTo（）

滚动此视图，填充将不再有效。所谓“不再有效”，是指在

画布上绘制的内容不考虑视图的填充，如下图所示：


我想知道这方面是否有解决办法？（PS：不要告诉我使用
TextView
而不是自己制作。我之所以这样做是出于某种原因，我想解决的唯一问题是填充内容，而不是一些出色的替代品，谢谢！）

编辑：
我的xml

在我看来：

public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    ......
    setMeasuredDimension(getPaddingLeft()+contentWidth+getPaddingRight()
    ,getPaddingTop()+contentHeight+getPaddingBottom());
    //whereas the contentWidth and contentHeight is determined by the widthMeasureSpec 
    // and heightMeasureSpec and some certain logic inside the view.
    // I don't think this will cause the view's content to exceed the conten area
}

在我的脑海里：

public void onDraw(Canvas canvas){
    Path path = new Path();
    for(String eachLine: text){
        path.moveTo(startX,startY);
        path.lineTo(endX,endY);
        canvas.drawTextOnPath(eachLine,path,0,0,painter);
        ...
    }
    ....
//the startX,startY,endX, endY has already took the padding into consideration.
//*NOTE: The only solution that I can think of is that I control this 
//drawing logic according to the padding. But this approach still won't fix the 
//problem, for example: what if I scroll half line height? How do I draw the 
//half of the line? So there must be some other approach that I don't know.
}

发布您的xmlcode@SathishKumarJ
如果这很重要。发布完整的xmlcode@SathishKumarJ我已经添加了一些代码，如果还不够的话，我将添加更多细节code@SathishKumarJ
