There are multiple textview marquee problems in Fragment

================================= Problem description ========================== =
An activity contains multiple fragment, 1, 2, 3, 4
There are two textviews in fragment1. When fragment1 is started for the first time, the marquee can run normally;
When I jump to another fragment and then return to fragment1, will the marquee be no longer running?
Is this the focus of textview?
Please help me solve this problem ....
=============================== Solution 1 ========================== ===
It should not be. It should be a life cycle issue. You should not write the marquee in oncreateview ,,,
