离开父级时，Android 视图消失 [英] Android View Disappearing When Go Outside Of Parent

问题描述

我在这个 LinearLayout 中有一个 LinearLayout 和 ImageView.

I have a LinearLayout and ImageView inside this LinearLayout.

ImageView 有翻译效果.

There is a translation effect for ImageView.

// v = ImageView    
ObjectAnimator animation2 = ObjectAnimator.ofFloat(v, "translationY", 200);
                        animation2.setDuration(3000);
                        animation2.setTarget(v);
                        animation2.start();

动画工作但当 ImageView 超出 LinearLayout 时它消失了.

Animation working but it's disappearing when ImageView go outside of LinearLayout.

如何在不修改 LinearLayout 高度的情况下修复它.

How can i fix it without modify LinearLayout's height.

推荐答案

找到 ImageView 所属的 ViewGroup 并应用 ViewGroup.setClipChildren(false).默认情况下，子视图的绘制仅限于父视图组的边界.

Find the ViewGroup that the ImageView belongs to and apply ViewGroup.setClipChildren(false). By default, the drawing of the children is limited to the bounds of the parent ViewGroup.
