android - how to download images with bad quality? -


i have recyclerview imageview , textview , , populate using download in bad quality accelerate download process.

the imageview has onclick method display dialog image downloaded background, so, want download image in bad quality , when user clicked in image , download image in hight quality.

this code download:

try {      ruta = "http://192.168.1.67/apptequila/fotos/" + usuariojson + "/" + fotojson;      url url = new url(ruta);      httpurlconnection connection = (httpurlconnection) url.openconnection();     connection.setconnecttimeout(15000);     connection.connect();     inputstream input = connection.getinputstream();     bitmap = bitmapfactory.decodestream(input);        }catch (sockettimeoutexception e){     cancelarhilo(3);     } catch (exception e) {     log.i("sms", "error al obtener foto: " + e.tostring());      bitmap = bitmapfactory.decoderesource(getresources(), r.drawable.sin_perfil);      }      data.add(new mimodel(nombrejson, categoriajson, likesjson, lemajson, bitmap, idsjson,latitudjson,longitudjson,distanciajson));

code of onclick imageview:

    public void pressimage(final int position) {         customdiag = new dialog(mainactivity.this);         customdiag.requestwindowfeature(window.feature_no_title);         customdiag.setcontentview(r.layout.dialog);                     relativelayout relativelayout = (relativelayout)customdiag.findviewbyid(r.id.root);                 drawable drawable = new bitmapdrawable(getapplicationcontext().getresources(),                         data.get(position).getimagen());                 if(build.version.sdk_int > 16) {                     relativelayout.setbackground(drawable);                 }else{                     relativelayout.setbackgrounddrawable(drawable);                 }                  customdiag.show(); }

why want that? use picasso or volley allow downloading/caching of images. display images in listviews extremely well. mitigate issue of attempting reduce memory burden making images "bad".
