my image

here xml code:

<linearlayout                         android:layout_width="match_parent"                         android:layout_height="match_parent"                         >                          <android.support.v4.view.viewpager                             android:layout_width="200dp"                             android:layout_height="match_parent"                             android:layout_gravity="center"                             android:id="@+id/view_pager">                          </android.support.v4.view.viewpager>                      </linearlayout>                  </linearlayout> 

her define adapter:

public class customswipadapter extends pageradapter {     private context context;     private layoutinflater layoutinflater;     bitmap[] bitmaps;     public customswipadapter(context context, bitmap[] bitmaps)     {         this.context=context;         this.bitmaps=bitmaps;     }     @override     public int getcount() {         return bitmaps.length;     }      @override     public boolean isviewfromobject(view view, object object) {         return (view==( linearlayout)object);     }      @override     public float getpagewidth(int position) {         return 0.7f;     }      @override     public object instantiateitem(viewgroup container, int position) {         layoutinflater=(layoutinflater)context.getsystemservice(context.layout_inflater_service);         view item_view=layoutinflater.inflate(r.layout.swip_layout,container,false);         imageview imageview=(imageview)item_view.findviewbyid(r.id.swip_image );         imageview.setimagebitmap(bitmaps[position]);         //item_view.setpadding(0,0,0,0);         item_view.setbackgroundcolor(color.argb(255, 255, 255, 255));         container.addview(item_view);         return item_view;     }      @override     public void destroyitem(viewgroup container, int position, object object) {         container.removeview((linearlayout)object);     } } 

here show view pager in fragment:

private void compressing()     {         bytearrayoutputstream stream=new bytearrayoutputstream();         for(int i=0;i<icons.length;i++)             icons[i].compress(bitmap.compressformat.jpeg, 40, stream);         adapter=new customswipadapter(getactivity(),icons);         viewpager.setadapter(adapter);         viewpager.setoffscreenpagelimit(adapter.getcount());          viewpager.setpagemargin(15);          viewpager.setclipchildren(false);      }
