android - Loading Bitmaps and display in ImageView Efficiently -

my program decode bitmap , display it.

the origin decode code , display code works perfect on pc.

when use code in android device, code can decode stream.

the problem image show in imageview is't efficiently.

below part of code

i use thread call decode function , show on imageview

class processdata extends thread{     message message;         string obj="run";         readrawfileimage readmyrawdata=new readrawfileimage();       public void run() {              log.e("///enter processdata thread ","processdata thread");            while(true){         bitmap image=bitmap.createbitmap (320, 240, bitmap.config.rgb_565);                     image.setpixels(pixeldata,0,320 ,0 ,0,320,240);         message = handler.obtainmessage(1,obj);         handler.sendmessage(message);             }    public handler handler = new handler(){        @suppresslint("newapi")     @override     public void handlemessage(message msg) {             super.handlemessage(msg);                        string msgstring = (string)msg.obj;              if (msgstring.equals("run"))             {             log.e("///enter handler ","setimagebitmap");                                                                                                                              myimageview.setimagebitmap(image);              }       } };

and set bitmap again!

and show kind of 10605k/13575k, paused 11ms+5ms, total 50ms again~~

imageview not built video previews. , don't create bitmap's on fly in real time applications either.

use surfaceview,textureview or surfacetexture rendering camera frames.
