如何调用显示卡片的信息以及显示卡片的高度。
我正在制作一个平衡的三元闹钟，我想根据卡片调整脸部的大小。
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：制作一个标志并找到以下代码可放入onPeekCardPositionUpdate（）的高度
yesCard = bounds.top != (int)0; // boolean that will be true if a card is showing.
cardHeight = (float)bounds.top;
