Demonstration 2: PagerTabStrip

Figure 4 PagerTabStrip

 
In the official document, PagerTabStrip and PagerTitleStrip are described as "PagerTabStrip is an interactive indicator of the current, next, and previous pages ofViewPager. "And" PagerTitleStrip is a non-interactive indicator of the current, next, and previous pages ofViewPager."
To put it simply, PagerTabStrip and PagerTitleStrip can both implement slide switching to the Tab page, but PagerTabStrip also implements switching to the Tab page by clicking the Tab, while PagerTitleStrip cannot.

Demonstration 3: ViewPager and dynamic Fragment

Figure 5 ViewPager and dynamic Fragment

 
The difference between FragmentStatePagerAdapter and FragmentPagerAdapter is that FragmentStatePagerAdapter only exists in the previous Fragment, and other Fragment will be destroyed, which is suitable for loading multiple data. FragmentPagerAdapter is applicable to all Fragment, therefore, it is not suitable for loading a large number of data slices or something, and it is easy to cause memory overflow.
