android - ImageView image not resizing with ImageView -


i have tablelayout cells of imageviews. trying create zooming effect incrementing size of imageviews in tabel. works zooming out( picture resizes imageview) but, problem zooming in. picture not resize when imageview made bigger.

here example: enter image description here

i want image same size imageview(each black square imageview)

here code zooming ( tips on better implementation appreciated, don't want use pinch zoom ).

zoomindex ranges -2, 2. (only allow them zoom twice in each direction) zoominthreshold = 2, zoomoutthreshold = -2.  defaultsize = 50, zoomincrement = 15;                   if(zoomindex < zoominthreshold)                     defaultsize += zoomincrement;                   for(int = 0; < table.getchildcount(); ++i)                 {                     tablerow row = (tablerow)table.getchildat(i);                     for(int r = 0; r < row.getchildcount(); ++r)                     {                         imageview img = (imageview)row.getchildat(r);                          if(zoomindex  < zoominthreshold)                         {                             tablerow.layoutparams imglayoutparams = new tablerow.layoutparams(                                     defaultsize,                                     defaultsize                             );                             img.setlayoutparams(imglayoutparams);                              if(img.getdrawable() != null)                             {                                 img.setadjustviewbounds(true);                                 img.setmaxheight(defaultsize);                                 img.setmaxwidth(defaultsize);                                 img.setscaletype(imageview.scaletype.center_inside);                             }                         }                     }                 }                 if(zoomindex < zoominthreshold)                     zoomindex++;

figured out problem, problem happens when load drawings xml files. had add line when loading drawing

img.setadjustviewbounds(true);

this how fits in:

                if(drawableid != -1)                 {                     bitmap pic = bitmapfactory.decoderesource(getresources(), drawableid);                     bitmap resizedbitmap = bitmap.createscaledbitmap(pic, 50, 50, true);                     im.setimagebitmap(resizedbitmap);                      ic.setimage(im);                      im.settag(ic);                      im.setadjustviewbounds(true);                      //rotate icon                     im.setscaletype(imageview.scaletype.matrix);                     matrix matrix = new matrix();                     matrix.set(im.getimagematrix());                     matrix.postrotate(rotangle, pic.getwidth() / 2, pic.getheight() / 2);                     im.setimagematrix(matrix);                      im.setonlongclicklistener(longlisten);//only set listener if there there                 }

i had img.setadjustviewbounds(true); in zoom buttons press.

postgresql - how to get points from linestring postgis -

i have linestring (0 0 , 2 4 , 5 5); i need output in form : x (1st cell) || y (2nd cell) 0 || 0 2 || 4 5 || 5 and same polygon. how ? you can use st_x , st_y in conjunction st_pointn x , y of individual points, , use generate_series create index each point of linestring, eg, with line (select st_geomfromtext('linestring(0 0, 2 4, 5 5)') geom) select st_x(st_pointn(geom,num)) x, st_y(st_pointn(geom,num)) y line, (select generate_series(1, (select st_numpoints(geom) line)) num) series;
