che sto cercando di attuare viewpager utilizzando MultiViewPager e utilizzo di Google zoomoutpageTransformer come effetto, lo scopo è raggiungere qualcosa di simile a questa immagine:MultiViewPager + ZoomOutPageTransformer non funziona correttamente
ma non riesco a visualizzare quelli due pagine a destra e a sinistra, ogni volta che ottengo una singola pagina in mezzo allo schermo! questo è il mio visualizzazione del codice cercapersone:
mViewPager.setPageMargin(
-64);
mAdapter = new ViewPagerAdapter(getActivity(), mClasses);
mViewPager.setPageTransformer(true, new ZoomOutPageTransformer());
mViewPager.setAdapter(mAdapter);
questo è il mio viewpager in xml:
<ir.phzrobin.Utils.MultiViewPager
android:id="@+id/viewPager"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_margin="20dp"
app:matchChildWidth="@+id/textview_class_title" >
</ir.phzrobin.Utils.MultiViewPager>
e questo è il mio layout di pagina viewpager:
<TextView
android:id="@+id/textview_class_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:layout_gravity="top"
android:layout_margin="5dp"
android:gravity="center_horizontal"
android:padding="10dp"
android:text="fsafjabf"
android:textAlignment="gravity"
android:textColor="@color/white"
android:textSize="17sp" />
<TextView
android:id="@+id/textview_class_teacher"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/textview_class_title"
android:layout_centerVertical="true"
android:layout_margin="5dp"
android:gravity="center_horizontal"
android:padding="10dp"
android:text="fsafjabf"
android:textAlignment="gravity"
android:textColor="@color/white"
android:textSize="17sp" />
<ImageView
android:id="@+id/button_options"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_margin="20dp"
android:layout_marginRight="2dp"
android:background="@drawable/overflow" />
</RelativeLayout>
quello che ho provato è this e anche la risposta dello sviluppatore multiviewpager da here qualcuno può aiutarmi per favore a raggiungere un obiettivo? grazie
questo è adattatore vista cercapersone:
public class ViewPagerAdapter extends PagerAdapter {
// ImageLoader imageLoader = ImageLoader.getInstance();

this.items = items;
notifyDataSetChanged();

DatabaseHandler _db = new DatabaseHandler(ContextVal

_db.deleteClass(items.get(pos));
_db.deleteClassNotes(items.get(pos).getID());
ContextVal.mViewFragment.RefreshViewPager(); // Refresh Items !

dialog.dismiss();
}
});
builder.setNegativeButton("خیر", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// Do nothing
Log.e("onClick", "NO");
dialog.dismiss();
}
});
AlertDialog alert = builder.create();
alert.show(); }
return true;
}
});
popup.show();
}
});
container.addView(view, 0);
return view;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
// TODO Auto-generated method stub

}
Si prega di inserire il codice per ViewPagerAdapter –
