Android imitation news top navigation tab switching effect

Recently, due to personal interest, I wrote a demo that imitates the navigation tab at the top of the news. See the figure below for details.

So basically we'll use this knowledge.

1.Fragment 2. FragmentPagerAdapter 3. horizontalscrollview 4. PopupWindow

OK, then go to the first step first.

In order to implement the top label, we need to use horizontalscrollview, because the original horizontalscrollview control can no longer meet our needs. So here we customize a horizontalscrollview

After that, do you need to write a fragment? In order to display the effect in the figure, we will customize one here to facilitate control

news_ fragment. xml

OK, for ease of control, let's write an adapter

After that, you're almost ready to write the activity code.

actiivty_ top_ news. xml

The above is the whole content of this article. I hope it will be helpful to your study, and I hope you can support programming tips.
