共享元素过渡动画问题

Question

我有一个LoginActivity，其中包含两个按钮登录和注册。我正在尝试分享从LoginActivity到RegistrationActivity的注册按钮。过渡动画正在发生，但动画并不顺利。问题是注册按钮在移至LoginActivity之前占据RegistrationActivity的整个高度和宽度。

以下是问题的屏幕截图。您可以看到注册按钮，其中包含布局的整个高度和宽度：

我的LoginActivity代码，我跳转到ResgitrationActivity：

Intent intent = new Intent(LoginActivity.this, RegistrationActivity.class);
                ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(LoginActivity.this, register, "register");
                startActivity(intent, options.toBundle());

在我onPause()和LoginActivity的{​​{1}}中我称之为：

RegistrationActivity

这是我的@Override protected void onPause() { super.onPause(); overridePendingTransition(0, 0); } ：

style.xml

我正在使用Marshmallow驱动的Android设备进行测试。 为什么动画不流畅？
