i using library,https://github.com/dm77/zbarscanner

how customize size of scanner frame?

protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate);

    if(!iscameraavailable()) {         // cancel request if there no rear-facing camera.         cancelrequest();         return;     }      // hide window title.     requestwindowfeature(window.feature_no_title);     getwindow().addflags(windowmanager.layoutparams.flag_fullscreen);      mautofocushandler = new handler();      // create , configure imagescanner;     setupscanner();      // create relativelayout container hold surfaceview,     // , set content of our activity.     mpreview = new camerapreview(this, this, autofocuscb);     setcontentview(mpreview); } 

you wrap in framelayout:

    mpreview = new camerapreview(this, this, autofocuscb);      //create framelyout hold views     framelayout layout = new framelayout(this);     framelayout.layoutparams layoutparams=new framelayout.layoutparams(viewgroup.layoutparams.match_parent, viewgroup.layoutparams.match_parent, gravity.center_horizontal|gravity.center_vertical);     layout.setlayoutparams(layoutparams);      //example of toolbar view add     toolbar bar = (toolbar) layoutinflater.from(this).inflate(r.layout.toolbar_general, layout, false);      layout.addview(mpreview);//add camerapreview     layout.addview(bar);//<----add example toolbar     //layout.addview(imageoverlay1);//<----this you'll add more views     //layout.addview(imageoverlay2);     setcontentview(layout); 

hope helps.
