after loading a picture, imageview does not update

Question

When i press load button, im suppose to go to the galley, choose a picture and then set the imageview img to that picture. The problem is after i choose a picture in galley, the imageview does not update. However, if i press load button a second time, it take a second or two to load the galley and in that time, imageview will load the picture i previously choosen. Can someone help me so i can get imageview to refresh correctly

 load.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { Intent intent = new Intent(); intent.setType("image/*"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE); try { FileInputStream in = new FileInputStream(selectedImagePath); bMap = BitmapFactory.decodeStream(in); img.setImageBitmap(bMap); if (in != null) { in.close(); } img.invalidate(); } catch (Exception e) {} } });

Well, this doesn't work this way :) You should move your code for loading and setting the bitmap to the onActivityResult method. Also it's a very bad practive to catch an instance of Exception - try catching only the respective checked exception here - i.e FileNotFoundException or something -you can delete your try - catch clasuse and afterwards pres ctrl + 1 in Eclipse while you have selected the FileInputStream in = new ... row --> choose the surround with try-catch option and eclipse will auto-generate for you the appropriate catch clause( and here I mean just the proper checked exception to be handled, not the catch clause body :) ).

thanks, after i put loading and setting bitmap to my onactivityresult, it worked
