java - Aligning right in android only work for last view added -

i'm trying align right dynamically several imageviews last 1 aligned.

in order best understanding here picture:

the activity layout set way:

<scrollview         android:layout_width="match_parent"         android:layout_height="match_parent"         android:fillviewport="true"         android:id="@+id/scrollview"         android:layout_below="@+id/button">          <linearlayout             android:id="@+id/imagem"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:orientation="vertical" >          </linearlayout>     </scrollview> 

and in code within linearlayout called imagem add more layouts in order give me final result, here code adding single line:

        linearlayout layout = (linearlayout)findviewbyid(r.id.imagem);         linearlayout llay = new linearlayout(this);         linearlayout comandos = new linearlayout(this);         comandos.setorientation(linearlayout.horizontal);         comandos.setgravity(gravity.right);         llay.setorientation(linearlayout.horizontal);         textview tv = new textview(this);         tv.settext(titulo);         tv.settypeface(null, typeface.bold);         tv.settextsize(tv.gettextsize()*1.05f);         textview tv2 = new textview(this);         tv2.settext(descricao);         layout.addview(tv);         layout.addview(llay);         llay.addview(tv2);         imageview image = new imageview(this);         image.setimagedrawable(e);         comandos.addview(image, new linearlayout.layoutparams(math.round(80*reducao),math.round(60*reducao)));         llay.addview(comandos, new linearlayout.layoutparams(linearlayout.layoutparams.wrap_content,linearlayout.layoutparams.wrap_content,gravity.right)); 

the way add several images keep creating new imageviews , adding them "comandos" layout.

is there mistake making correct alignment last line?

horizontal linearlayout not support gravity.right or left, not know "empty" space left between views.

a simple solution set textview's weight 1, "push" image right , take empty space. so:

    linearlayout layout = (linearlayout)findviewbyid(r.id.imagem);     linearlayout llay = new linearlayout(this);     linearlayout comandos = new linearlayout(this);     comandos.setorientation(linearlayout.horizontal);     llay.setorientation(linearlayout.horizontal);     textview tv = new textview(this);     tv.settext(titulo);     tv.settypeface(null, typeface.bold);     tv.settextsize(tv.gettextsize()*1.05f);     textview tv2 = new textview(this);     tv2.settext(descricao);     tv2.setlayoutparams(new linearlayout.layoutparams(0, viewgroup.layoutparams.wrap_content, 1)); // setting weight 1     layout.addview(tv);     layout.addview(llay);     llay.addview(tv2);     imageview image = new imageview(this);     image.setimagedrawable(e);     image.setlayoutparams(new linearlayout.layoutparams(math.round(80*reducao),math.round(60*reducao)));     comandos.addview(image);     llay.addview(comandos, new linearlayout.layoutparams(linearlayout.layoutparams.wrap_content,linearlayout.layoutparams.wrap_content)); 

edit: did not realise adding more images comandos, fixed answer.
