android - How to create imageviews dynamically on runtime? -


im building android app needs create max of 1-4 imageviews depending on number of images need display on screen. have written small code doesn't seem divide screen equally on 4 imageviews though. top 2 little larger bottom 2 in case. following code cant think issue is

private void createscreen() {     int screenheight = getwindowmanager().getdefaultdisplay().getheight();     int screenwidth = getwindowmanager().getdefaultdisplay().getwidth();      int matrixn = 2;      int maxwforeachscreen = screenwidth / matrixn;     int maxhforeachscreen = screenheight / matrixn;     relativelayout relativelayout = (relativelayout) findviewbyid(r.id.relativelayoutfullscreen);      imageview imgview1 = new imageview(liveviewer.this);     imageview imgview2 = new imageview(liveviewer.this);     imageview imgview3 = new imageview(liveviewer.this);     imageview imgview4 = new imageview(liveviewer.this);      int size = 3;      if(size >= 3 && size <= 4)     {         imgview1.setimageresource(r.drawable.icon);         imgview2.setimageresource(r.drawable.icon);         imgview3.setimageresource(r.drawable.icon);         imgview4.setimageresource(r.drawable.icon);          relativelayout.layoutparams params1 = new relativelayout.layoutparams(100, 100);         relativelayout.layoutparams params2 = new relativelayout.layoutparams(100, 100);         relativelayout.layoutparams params3 = new relativelayout.layoutparams(100, 100);         relativelayout.layoutparams params4 = new relativelayout.layoutparams(100, 100);          params1.height = maxhforeachscreen/2;         params1.width = maxwforeachscreen/2;          params2.height = maxhforeachscreen/2;         params2.width = maxwforeachscreen/2;          params3.height = maxhforeachscreen/2;         params3.width = maxwforeachscreen/2;          params4.height = maxhforeachscreen/2;         params4.width = maxwforeachscreen/2;          params1.setmargins(0, 0, 0, 0);         params2.setmargins(maxwforeachscreen/2, 0, 0, 0);         params3.setmargins(0, maxhforeachscreen/2, 0, 0);         params4.setmargins(maxwforeachscreen/2, maxhforeachscreen/2, 0, 0);          relativelayout.addview(imgview1, params1);         relativelayout.addview(imgview2, params2);         relativelayout.addview(imgview3, params3);         relativelayout.addview(imgview4, params4);           } }

you can set weightsum of parentlayout equal number of views.. , set 1 weight of every view...this make each views occupy equal space..

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
