如何分別移動每個矩形？

Question

我有五個可繪制的矩形，我必須將矩形設置為 (-20,-15,-10,-5,0) 度角。 每個矩形都有四個 colors 燈罩。 現在我需要一個一個地為每個矩形設置動畫，如果用戶從左向右拖動，則頂部矩形從左向右移動。

問題是，我不能單獨移動每個矩形。 如何分別識別和實現每個矩形？

這是我必須做的示例快照。 http://postimage.org/image/13sa96sbo/

public ColorFanDraw(Context context) {
    super(context);
    // TODO Auto-generated constructor stub
}


@Override
protected void onDraw(Canvas canvasObject) {

    int x = 100;
    int y = 50;
    int width = 70;
    int convasSize =200;       

    Paint thePaint = new Paint();

    thePaint.setColor(mTouchedColor-200);   
    canvasObject.rotate(-15, centerX,centerY); 
    canvasObject.drawRect(new Rect(x,y,x+width,y+convasSize), thePaint);

    thePaint.setColor(mTouchedColor-50);    
    canvasObject.rotate(10, centerX,centerY);
    canvasObject.drawRect(new Rect(x,y,x+width,y+convasSize), thePaint);

    canvasObject.rotate(10, centerX,centerY);
    thePaint.setColor(mTouchedColor);
    canvasObject.drawRect(new Rect(x,y,x+width,y+convasSize), thePaint);

    rotation = AnimationUtils.loadAnimation(contextObj,
                                     R.anim.view_transition_in_left);

    ImageView img = new ImageView(contextObj);

    img.startAnimation(rotation);


}

Answer 1

在將矩形對象繪制到 Canvas 之前，您需要將它們存儲在變量中。

Rect rectangle1 = new Rect(x,y,x+width,y+convasSize);
canvasObject.drawRect(rectangel1, thePaint);

Rect rectangle2 = new Rect(x,y,x+width,y+convasSize);
canvasObject.drawRect(rectangel2, thePaint);

等等。

然后，您可以在執行 animation 的任何地方參考各個矩形。
