android - How to make all child view at vertical center of a horizontal LinearLayout which gravity is center_vertical after add views to it -

here horizontal linearlayout, set it's gravity center_vertical, add 2 views linearlayout, height of first view bigger other, result second view align top of first view, not @ vertical center of linearlayout. how make child view @ vertical center, ideas?

here code:

context context = getactivity(); mpicturecontainer = new linearlayout(context); mpicturecontainer.setbackgroundcolor(0xffffffff); mpicturecontainer.setgravity(gravity.center_vertical); mpicturecontainer.setorientation(linearlayout.horizontal); int leftrightmargin = getresources().getdimensionpixelsize(r.dimen.leftrightmargin); mpicturecontainer.setpadding(leftrightmargin, 0, leftrightmargin, 0); //... maddpicbtn = new imageview(context); maddpicbtn.setlayoutparams(new linearlayout.layoutparams(utils.dip2px(77f), utils.dip2px(77f))); maddpicbtn.setscaletype(scaletype.center_crop); maddpicbtn.setimagedrawable(statelistfactory.createstatelistdrawable(r.drawable.add_prs, -1, r.drawable.add)); //... mpicturecontainer.removeallviews(); arraylist<string> pictures = (arraylist<string>) data.getserializableextra("pictures"); int size = pictures.size(); (int = 0; < size; i++) {     string path = pictures.get(i);     final view view = layoutinflater.from(getactivity()).inflate(r.layout.status_pic_item, mpicturecontainer, false);     view.settag(path);     imageview imageview = (imageview) view.findviewbyid(r.id.picture);     imageview delpicbtn = (imageview) view.findviewbyid(r.id.delpicbtn);     delpicbtn.setimagedrawable(statelistfactory.createstatelistdrawable(r.drawable.del_prs, -1, r.drawable.del));                delpicbtn.setonclicklistener(new onclicklistener() {         @override         public void onclick(view v) {             mpicturecontainer.removeview(view);             if (mpicturecontainer.getchildcount() < 4 && maddpicbtn.getparent() != mpicturecontainer) {                 mpicturecontainer.addview(maddpicbtn);             }         }     });     mpicturecontainer.addview(view, i);     imageloader.loadimage(imageview, "file://" + path); } if (mpicturecontainer.getchildcount() < 4) {     mpicturecontainer.addview(maddpicbtn); } 

and here layout status_pic_item :

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="81dp"     android:layout_height="81dp"     android:layout_marginright="3dp" >      <imageview         android:id="@+id/picture"         android:layout_width="77dp"         android:layout_height="77dp"         android:layout_alignparentbottom="true"         android:scaletype="centercrop" />      <imageview         android:id="@+id/delpicbtn"         android:layout_width="20dp"         android:layout_height="20dp"         android:layout_alignparentright="true"         android:clickable="true" />  </relativelayout>
