I have a problem in my code, can someone help me?
I need to make a game history of applications, for example, Messenger app I want to display a list of images and videos in viewpager automatically or manually
I do this, but I ran into some problem
At first:
when the page with the image is displayed, and the sound reproduced during the playback of the image is played on the next page, because the pager loads the next fragment, which I used mViewPager.setOffscreenPageLimit (0); but i did nothing
Second:
when I move manually with the video so that the image does not stop when I was looking for a solution, I found this:
public void setUserVisibleHint(boolean isVisibleToUser) { super.setUserVisibleHint(isVisibleToUser); if (this.isVisible()) { if (!isVisibleToUser)
it stops the player, but if there is video on the next page, it does not play How can I solve this problem?
My code is:
