fragmentpageradapter

问题 I'm trying to dynamically add and remove Fragments from a ViewPager, adding works without any problems, but removing doesn't work as expected. Everytime I want to remove the current item, the last one gets removed. I also tried to use an FragmentStatePagerAdapter or return POSITION_NONE in the adapter's getItemPosition method. What am I doing wrong? Here's a basic example: MainActivity.java public class MainActivity extends FragmentActivity implements TextProvider { private Button mAdd;

问题 I did search all the question related to this but could not find any solution here is my code. private Toolbar toolbar; private TabLayout tabLayout; private ViewPager viewPager; MyFragmentPagerAdapter pagerAdapter; ArrayList<String> titles = new ArrayList<String>(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_scrollable_tabs); new JSONAsyncTask() .execute(My_Url); toolbar = (Toolbar) findViewById(R.id

问题 This is a continuation from the question I 1st asked here, Creating a new ArrayPagerAdapter with variety of Fragments. You were dead on about me using the wrong ArrayAdapter I just needed to use the one that has v4 support. I have posted the code for it below. One of the next blocks i'm getting stuck on right now is creating the PageDescriptor objects in the ArrayList passed into SimplePageAdapter. I've tried copying and pasting the SimplePageDescriptor class used in the Demo into my code but

问题 I'm using FragmentPageAdapter to have multiple tabs within my app. 1 of those tabs is a ListFragment that is supposed to be replaced by another fragment onItemClick , using FragmentTransaction . The change replace works perfectly if I add the ListFragment to a FrameLayout inside an Activity , but I'm not sure how to do this using FragmentPagerAdapter . Here's a better explanation: Tab1 Tab2 Tab3 Tab4 fragment fragment fragment fragment subclass subclass subclass listview after clicking on one

问题 I am using Xamarin and am having some code trouble in relation to my ViewPager not displaying my Views. Here is my code: MainActivity: public class MainActivity : FragmentActivity { protected override void OnCreate (Bundle bundle) { base.OnCreate (bundle); SetContentView (Resource.Layout.activity_main); var pager = FindViewById<ViewPager>(Resource.Id.viewPager); pager.Adapter = new MyPagerAdapter(SupportFragmentManager); } } MyPagerAdapter: public class MyPagerAdapter : FragmentPagerAdapter {

问题 I am using a FragmentStatePagerAdapter in combination with a view pager, which is nested in a fragment on Android. Thus, I am using the ChildFragmentManager in combination with the FragmentStatePagerAdapter to create my fragments. So far so good, but here is the problem: If I open a different Activity without finishing the activity that hosts the fragment with the view pager and afterwards resume it, the fragment that was selected in the ViewPager is empty. If I switch the fragment in the

问题 i have created my project using this material design example. i have modified the code and now i have 5 tabs now. And now i have created 5 fragment classes and loading it on the view pager. now what i want is, i want to pass the selected sliding menu position as a parameter to the fragment which i am loading. Here the problem is, i can pass the parameter(using Bundle) to the FragmentPagerAdapter , but it is not reloading the fragments based on the parameter i'm passing! the thing is it is not

问题 I have an Activity which extends ActionBarActivity and activity has following code in xml. <android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent" /> It has just ViewPager. I want to display Image with list of options so I opted for creating a fragment with layout I want to be shown as a part of ViewPager. I created an adapter extending FragmentPagerAdapter as

问题 My tabLayout is exhibiting this strange behaviour You can see that by swiping the tabs after clicking a row the content from a tab gets mixed with the content from another. Each row in the listView (the gif only shows one row, of course there'd be more) can be clicked to update a value from the database on which the eye icon is based. So, I want the icon to update at the same time. In the activity source file I also declared the PagerAdapter for the fragment tabs, the fragment and the

问题 I have ~20 fragments inside FragmentPagerAdapter that contains a list where it picks the fragments from so theres no recreation of fragments. private List<TitledFragment> fragments; public SectionsPagerAdapter(FragmentManager fm) { super(fm); this.fragments = new ArrayList<TitledFragment>(); } @Override public Fragment getItem(int i) { return fragments.get(i).getFragment(); } @Override public int getCount() { return fragments.size(); } @Override public CharSequence getPageTitle(int position)
