Sei que já existem alguns tópicos sobre isso aqui, mas não consegui encontrar uma solução para trabalhar no meu caso.

Tenho uma galeria deslizante de trabalho usando um @ personalizaFragmentActivity eFragmentPagerAdapter que contém uma lista de fragmento

Dentro doFragmentActivity é umImageView "excluir". Se clicada, a funçãodeleteMedia() é chamado e, em seguida, deve remover o @ atuFragment e os seguintesFragment deve ser exibido. Como eu teria que fazer isso no meu exemplo?

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();
}
}

Obrigado pela ajuda!
