在ViewPager中禁用动画 [英] Disabling animation in ViewPager

问题描述

我想在自定义 ViewPager 中禁用所有动画，以进行过渡。
此视图分页器包含四个选项卡-每个选项卡均加载 Fragment -，并且该视图分页器的作用是切换选项卡：例如，第一个选项卡是索引，第二个是地图，等等。

I'd like to disable all the animations for the transitions in my custom ViewPager. This view pager contains four tabs -and each tab loads a Fragment- and what the view pager does is to switch the tabs: for example first tab is the index, second is map, etc.

问题是，如果作为第一个选择的标签，我单击了第四个标签，我可以看到 ViewPager 经过第二个和第三个选项卡，然后在第四个选项卡上停止，我不希望这种情况发生。

The problem is that if, being the first tab chosen, I click on the fourth tab, I can see how the ViewPager goes through the second and third tab and stops on the fourth, and I don't want that to happen.

我尝试过禁用此 ViewPager 的所有动画，尝试将 setAnimation 用作 null 每次用户选择要显示的新标签，但仍然无法正常工作。

I tried to disable all the animations for this ViewPager trying to use a setAnimation to null every time the user chooses a new tab to be displayed, but it still doesn't work.

有什么想法可以实现吗？
提前谢谢！

Any idea to achieve this, please? Thanks a lot in advance!

编辑：我还尝试为每个<$覆盖 onCreateAnimation c $ c> Fragment 但仍然无法工作

I also tried to override onCreateAnimation for each Fragment but still not working

推荐答案

我终于发现：问题可能是只需调用 mViewPager.setCurrentItem（position）并使用 false 的额外参数即可解决，这是平滑滚动的方法 ViewPager 。
此后，滚动将完成而不会进行任何平滑处理，因此将看不到动画。

I finally found out: the issue can be solved by just calling the mViewPager.setCurrentItem(position) with an extra parameter to false, which is the smooth scroll for the ViewPager. After this, the scroll will be done without any smoothing and thus the animations won't be seen.
