Cómo quitar el fragmento de FragmentPagerAdapter?

Sé que hay algunos temas sobre esto aquí ya, pero no pude encontrar una solución que podría llegar a trabajar para mi caso.

Tengo una galería móvil de trabajo usando una FragmentActivity personalizada y FragmentPagerAdapter que contiene una lista de Fragmentos.

• mantener instancias de fragmentos dentro de FragmentPagerAdapter
• ¿Cuándo se llama a getItem de FragmentPagerAdapter?
• Eliminar Elemento + Desplazarse a Siguiente en Android ViewPager
• Android: limitar los fragmentos de carga con una viewPager
• Haga clic en la pestaña de Android

Dentro de la FragmentActivity hay un ImageView "delete". Si se hace clic en la función deleteMedia () se llama que entonces debe quitar el Fragmento actual y el fragmento siguiente debe ser mostrado. ¿Cómo tendría que hacer eso en mi ejemplo?

FragmentActivity:

public class GalleryPagerActivity extends FragmentActivity implements OnClickListener { private Intent intent; private SharedPreferences settings; private PagerAdapter mPagerAdapter; private ViewPager mPager; private List<Fragment> fragments; private List<WhiteboardMedia> wiList; private int selectedPosition; private LinearLayout llTop; private TextView tvTop; private ImageView delete; private ImageView share; private TextView tvCounter; private TextView tvFilename; private TextView tvFilesize; private TextView tvDate; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try { super.setContentView(R.layout.gallery_pager); intent = getIntent(); Type collectionType = new TypeToken<List<WhiteboardMedia>>(){}.getType(); wiList = gson.fromJson(intent.getStringExtra("wiList"), collectionType); selectedPosition = intent.getIntExtra("position", 1); llTop = (LinearLayout) findViewById(R.id.llTop); llTop.setOnClickListener(this); tvTop = (TextView) findViewById(R.id.tvTop); tvTop.setOnClickListener(this); delete = (ImageView) findViewById(R.id.imgDelete); delete.setOnClickListener(this); share = (ImageView) findViewById(R.id.imgShare); share.setOnClickListener(this); tvCounter = (TextView) findViewById(R.id.tvCounter); tvFilename = (TextView) findViewById(R.id.tvFilename); tvFilesize = (TextView) findViewById(R.id.tvFilesize); tvDate = (TextView) findViewById(R.id.tvDate); createContextMenu(); initDropbox(); } catch (Exception e) { Log.e("GalleryPagerActivity", e.getLocalizedMessage()); } } /** * Initialise the pager */ private void initialisePager() { mPager = (ViewPager) super.findViewById(R.id.viewpager); mPager.setAdapter(this.mPagerAdapter); mPager.setOnPageChangeListener(new GalleryPageListener(tvCounter, tvFilename, tvFilesize, tvDate, wiList)); mPager.setCurrentItem(selectedPosition, true); updatePage(selectedPosition); } public void updatePage(int position) { int focusedPage = position + 1; Log.i("onPageSelected", "page selected " + position); WhiteboardMedia wiImage = wiList.get(position); String imageDate = "N/A"; try { Date dateTaken= new Date(); //wiImage.getDate(); SimpleDateFormat sdf = new SimpleDateFormat("yy/MM/dd"); imageDate = sdf.format(dateTaken); } catch (Exception e) { } try { tvCounter.setText(focusedPage + "/" + wiList.size()); tvFilename.setText(wiImage.getFilename()); tvFilesize.setText(wiImage.getSize() + "a"); tvDate.setText(imageDate); } catch (Exception e) { } } @Override protected void onResume() { super.onResume(); } @Override public void onDestroy() { super.onDestroy(); } private WhiteboardMedia getActiveWhiteboardImage() { return wiList.get(mPager.getCurrentItem()); } private final int DELETE = 1; @Override public boolean onCreateOptionsMenu(Menu menu) { menu.add(1, DELETE, 2, R.string.delete).setIcon(R.drawable.menu_btn_trash); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case DELETE: deleteMedia(); return true; } return super.onContextItemSelected(item); } @Override public void onClick(View v) { if (v == delete) { deleteMedia(); } } private void deleteMedia() { // TODO delete the active Fragment and display the next Fragment in the list } /****************************************************************************** * Context Menu *****************************************************************************/ private void createContextMenu() { // context menu stuff } @Override protected Dialog onCreateDialog(int id) { // stuff } } 

FragmentPagerAdapter:

 public class GalleryPagerAdapter extends FragmentPagerAdapter { private final List<Fragment> fragments; public GalleryPagerAdapter(FragmentManager fm, List<Fragment> fragments) { super(fm); this.fragments = fragments; } @Override public Fragment getItem(int position) { return this.fragments.get(position); } @Override public int getCount() { return this.fragments.size(); } } 

¡Gracias por la ayuda!

 mViewPager = (YourViewPager) findViewById(R.id.myPager); 

 public void destroyAllItem() { int mPosition = mViewPager.getCurrentItem(); int mPositionMax = mViewPager.getCurrentItem()+1; if (TABLE.size() > 0 && mPosition < TABLE.size()) { if (mPosition > 0) { mPosition--; } for (int i = mPosition; i < mPositionMax; i++) { try { Object objectobject = this.instantiateItem(mViewPager, TABLE.get(i).intValue()); if (objectobject != null) destroyItem(mViewPager, TABLE.get(i).intValue(), objectobject); } catch (Exception e) { Log.i(TAG, "no more Fragment in FragmentPagerAdapter"); } } } } @Override public void destroyItem(ViewGroup container, int position, Object object) { super.destroyItem(container, position, object); if (position <= getCount()) { FragmentManager manager = ((Fragment) object).getFragmentManager(); FragmentTransaction trans = manager.beginTransaction(); trans.remove((Fragment) object); trans.commit(); } } 

 @Override protected void onPostResume() { super.onPostResume(); if(this.mCustomPagerAdapter!=null){ this.mCustomPagerAdapter.notifyDataSetChanged(); } }
