我有這樣的佈局Android viewpager沒有顯示？
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
</ScrollView>
最後的LinearLayout顯示選項卡，但是當我切換他們沒有viewpager數據任何責任。我嘗試了tablayout創建另一個佈局，但它仍然不會工作..即時通訊調用這個從片段如下：
public class ProfileFragment : Fragment
{
private static Context _context;
private static Xamarin.Facebook.Profile _profile;
private CircleImageView imgProfile;
private TextView userName;
private TabLayout tabLayout;
private ViewPager viewpager;
public override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your fragment here
}
public static Fragment NewInstance(Activity context , Xamarin.Facebook.Profile profile)
{
_context = context;
_profile = profile;
Fragment fragment = new ProfileFragment();
return fragment;
}
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View view = inflater.Inflate(Resource.Layout.fragmentProfile, container, false);
imgProfile = view.FindViewById<CircleImageView>(Resource.Id.imageProfile);
tabLayout =view.FindViewById<TabLayout>(Resource.Id.tab_layout);
viewpager = view.FindViewById<ViewPager>(Resource.Id.pager);
userName = view.FindViewById<TextView>(Resource.Id.user_name);
userName.Text = _profile.Name;
Picasso.With(_context).Load(_profile.GetProfilePictureUri(180, 180)).Into(imgProfile);
FnInitTabLayout();
return view;
}
void FnInitTabLayout()
{
tabLayout.SetTabTextColors(Android.Graphics.Color.Aqua, Android.Graphics.Color.AntiqueWhite);
//Fragment array
var fragments = new Fragment[]
{
new ActivityFragment(),
new SportsFragment(),
new AboutFragment()
};
//Tab title array
var titles = CharSequence.ArrayFromStringArray(new[] {
"Feed",
"Sports",
"About",
});
//viewpager holding fragment array and tab title text
viewpager.Adapter = new ProileTabsAdapter(FragmentManager, fragments, titles);
tabLayout.SetupWithViewPager(viewpager);
}
}
當我把它的活動僅在標籤和viewpager他們內部並沒有上述佈局完美的工作，但在這種情況下不是。任何人都可以想到我做錯了什麼？
編輯：
這裏是尋呼機適配器
public class ProileTabsAdapter : FragmentPagerAdapter
{
private readonly Fragment[] fragments;
private readonly ICharSequence[] titles;
public ProileTabsAdapter(FragmentManager fm, Fragment[] fragments, ICharSequence[] titles) : base(fm)
{
this.fragments = fragments;
this.titles = titles;
}
public override int Count
{
get
{
return fragments.Length;
}
}
public override Fragment GetItem(int position)
{
return fragments[position];
}
public override ICharSequence GetPageTitleFormatted(int position)
{
return titles[position];
}
}
您是否實施了ViewPager適配器？分享您的viewpager適配器的代碼 – SripadRaj
我編輯帖子以包含適配器 – Drinv
視圖分頁器的wrap_content在滾動視圖內不起作用。嘗試設置layout_height查看尋呼機 –
