在pixcel找到距离

要计算一个视图底部与另一个视图顶部之间的距离:

View oneView = ...;
View otherView = ...;

RectF oneRect = calculeRectOnScreen(oneView);
RectF otherRect = calculeRectOnScreen(otherView);

float distance = Math.abs(oneRect.bottom - otherRect.top);

util方法:

public static RectF calculeRectOnScreen(View view) {
    int[] location = new int[2];
    view.getLocationOnScreen(location);
    return new RectF(location[0], location[1], location[0] + view.getMeasuredWidth(), location[1] + view.getMeasuredHeight());
}

在某些情况下,您需要替换view.getLocationOnScreento view.getLocationInWindow.
