                        });
                    }
                }
            }
        }

    } catch (Exception ex) {}   


}

在动画结束时，我调用removeview，然后发生错误。为什么？

这是android的一个奇怪问题，你无法在animationEnd中更改视图层次结构。

您所要做的就是推迟拨打电话：

@Override
public void onAnimationEnd(Animation animation) {
    post(new Runnable() {
        public void run() {
            myLinearLayoutAll.removeView(img2);
        }
    });
}

动画时出现Android removeview错误
