如何调用卡片正在显示的信息以及它正在显示的高度。

我正在研究一个平衡的三进制时钟，我想根据卡片调整脸部大小。

编辑：我找到了解决方案。

// detect the height of a card. And call resizers.
// baseLedge is the default bottom of the watch
// tallness is the height of the display
// tallable is the portion of the screen height offered to the face.
// ledge is the adjusted bottom of the watch
// ledgeSpace is a desired margin above the ledge
// puff is the ratio of the adjusted display to the standard display
// puffer() is a module (or method or whatever the correct term is) that applies the resizing.
    // no clue what the Override wrapper does or how it work.   
    @Override
    // Rect -> none
    public void onPeekCardPositionUpdate(Rect bounds) {
        super.onPeekCardPositionUpdate(bounds);
        if (!bounds.equals(mCardBounds)) {
            mCardBounds.set(bounds);
            if (bounds.top == 0){bounds.top = (int)tallness;}
            if (bounds.top < baseLedge || ledge != baseLedge) {
                ledge = Math.min(bounds.top, baseLedge);
                puff = (ledge - dispTop -) / tallable; 
                if (puff < (float).25) {puff = (float).25; }
                puffer ();
            }
            invalidate(); // redraw screen without updating time.
        }
    }

注意：做一个标志并找到高度，下面的代码可以放在 onPeekCardPositionUpdate()

yesCard = bounds.top != (int)0; // boolean that will be true if a card is showing.
cardHeight = (float)bounds.top;

你问的是偷看卡吗？如果是这样，则在该链接中记录了获取其尺寸。
