Я внедрил свое навигационное приложение с помощью навигационного ящика, но один из элементов открывал фрагмент с двумя вкладками.FragmentTabHost horizontal swipe
Вкладки Я реализовал «FragmentTabHost», потому что Roman Nurik не рекомендует использовать «ViewPager» с «NavigationDrawer».

Все работает отлично меня проблема у меня есть, что FragmentTabHost Можно ли осуществлять горизонтальную красть между вкладками?
Приложить код:
Main_Activity.xml
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"

<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"

mTabHost.setup(getActivity(), getChildFragmentManager(), R.layout.fragment1);
mTabHost.addTab(mTabHost.newTabSpec("noticas").setIndicator("Noticias"), FragmentTab1.class, null);
mTabHost.addTab(mTabHost.newTabSpec("promociones").setIndicator("Promociones"), FragmentTab2.class, null);
return mTabHost;
}
//Detach FragmentTabHost
@Override
public void onDetach() {
super.onDetach();
try {
Field childFragmentManager = Fragment.class
.getDeclaredField("mChildFragmentManager");
childFragmentManager.setAccessible(true);
childFragmentManager.set(this, null);
} catch (NoSuchFieldException e) {
throw new RuntimeException(e);
} catch (IllegalAccessException e) {
throw new RuntimeException(e);
}
}
//Remove FragmentTabHost
@Override
public void onDestroyView() {
super.onDestroyView();
mTabHost = null;
}
}
Может быть реализован горизонтальный красть с FragmentTabHost?
Я искал информацию, но все говорят, что такие вещи лучше использовать ViewPager.
Этот первый пример (в EDIT :) бесполезен. Он обеспечивает половину кода ... – Brandon
