问题 Here as you can see I used TabLayout , TabHost . I used TabLayout in first twice pictures. In third picture I used TabHost . Usually, TabLayout is looking better than TabHost / TabWidget .TabHost as you can see TabHost is deprecated. So, It would be better if I don't use TabHost . TabLayout isn't deprecated. Here is a question I asked someone said it is duplicate. I thought it was. Look, while I am using ViewPager and TabLayout I can't use those layout directly in MainActivity I meant I have

问题 I am working on my first Android application. I just came to discover Fragments and I need them to create a ViewPager to create nice transitions between my activities, but I fear that it's too late to implement that. I have to put all my code ( MainActivity ) in my MainFragment? Or just some pieces I don't know what I have to keep in my MainActivity Here is my code public class MainActivity extends FragmentActivity { ObjectAnimator anim; ObjectAnimator anim2; private int display, result,

问题 I am using scrollable TabLayout with a ViewPager. I want to make sure that at any given time I have 7 tabs displayed per page. Even if the total number of tabs is 10, I want to have 7 per page, and scroll to expose the other 3. I can't find a property to control the number of tabs displayed. 回答1: Eventually what worked for me was to calculate the desired size of each cell to get the total amount of tabs that I needed per page and set app:tabMaxWidth inside android.support.design.widget

问题 The app uses android viewpager2 (androidx.viewpager2:viewpager2:1.0.0-beta04) to show slides. Each slide have video on its top half and text on its bottom half.

Presentation Activity myViewPager2.setOrientation(ViewPager2.ORIENTATION_HORIZONTAL);

问题 I have a Activity with Custom SwipeRefreshLayout and a Vertical ViewPager which swipes vertically. (basically a deck of cards which can be refershed by using swipe to refresh). So Now when i try to swipe the Vertical Viewpager SwipeRefreshLayout handles the touch event and refresh the layout and the view pager's page does't move. Two things i tried but with no luck: Enable swipe to refresh layout only when user starts from the toolbar. MotionEvent.ACTION_DOWN event getY() gives toolbar's y

问题 I'm using a viewPager to display some forms. My problem is when i rotate the screen of the device and the viewPager is created again, it doesn't see the viewPager when he reaches the findViewById , it's always null . I have no idea how to handle it when rotation change.

So I'm quite blocked now. pager = (CustomViewPager) getActivity()
