android - Bizarre Invalidate behaviour -

i have custom viewgroup (custom2) inside custom viewgroup (custom1).

custom1 has imageview displaying rectshape shapedrawable , 2 textviews.

i set onclicklistener in custom2 removes imageview using this.removeviewat(0) , creates new textureview, calling this.addview (mtextureview, 0) , invalidate. textureview play video using mediaplayer.

here code:

public void settotextureview() {         //textureview when not debugging         textureview view;         view = (textureview) new textureview(mcontext);         view.setlayoutparams(new layoutparams(600, 500));         this.removeviewat(0);         this.addview(view, 0);         view.invalidate();         log.d("debug", "invalidate called");          view.setsurfacetexturelistener(new textureview.surfacetexturelistener() {             @override             public void onsurfacetextureavailable(surfacetexture surface, int width, int height) {                 surface msurface = new surface(surface);                  mediaplayer mmediaplayer = new mediaplayer(); //debug mediaplayer issues setting itemtodebug = "mediaplayer"                 try {                     mmediaplayer.setdatasource(mcontext, uri.parse("android.resource://" + mcontext.getpackagename() + "/" + r.raw.t));                     if (itemtodebug.equals("mediaplayer")) {                         log.d("mediaplayer", "data source set");                     }                     mmediaplayer.setsurface(msurface);                     if (itemtodebug.equals("mediaplayer")) {                         log.d("mediaplayer", "surface set");                     }                     mmediaplayer.prepare();                     if (itemtodebug.equals("mediaplayer")) {                         log.d("mediaplayer", "prepared");                     }                 } catch (ioexception e) {                     log.d("ioexception", e.getmessage());                 }                 mmediaplayer.setonpreparedlistener(new mediaplayer.onpreparedlistener() {                     @override                     public void onprepared(mediaplayer mp) {                         if (itemtodebug.equals("mediaplayer")) {                             log.d("debug", "media player prepared");                         }                         mp.start();                     }                 });             } 

now, notice bizarrely imageview disappears , empty space appears (of correct size) when click view, no video plays, although code appears execute fine upto invalidate();

however, can textureview surfacetexture , play video when interrupt program , go in (i.e pressing button takes screen open programs, , selecting activity again.)

i don't have understanding of happening pretty sure no surfacetexture being created because onattached() isn't being called.

does know might going on?

cheers,

the view disappears, need call requestlayout() in order draw else there.
