java - android take multiple image with camera -


i've made code capturing image using device built-in camera , archiving in database server. each time captures image , views it, make imageview layout dynamically (ex: image ic_launcher).

whenever ic_launcher image clicked, go mainactivity.java page, use of intent, take image.

my question is, how can view of captured images / archived images in uploadactivity.java?

note: image viewed in uploadactivity.java

mainactivity.java

 private void captureimage() {     intent intent = new intent(mediastore.action_image_capture);      fileuri = getoutputmediafileuri(media_type_image);      intent.putextra(mediastore.extra_output, fileuri);      // start image capture intent     startactivityforresult(intent, camera_capture_image_request_code); }  @override protected void onsaveinstancestate(bundle outstate) {     super.onsaveinstancestate(outstate);      // save file url in bundle null on screen orientation     // changes     outstate.putparcelable("file_uri", fileuri); }  @override protected void onrestoreinstancestate(bundle savedinstancestate) {     super.onrestoreinstancestate(savedinstancestate);      // file url     fileuri = savedinstancestate.getparcelable("file_uri"); }    /**  * receiving activity result method called after closing camera  * */ @override protected void onactivityresult(int requestcode, int resultcode, intent data) {     // if result capturing image     if (requestcode == camera_capture_image_request_code) {         if (resultcode == result_ok) {              launchuploadactivity(true);           } else if (resultcode == result_canceled) {              // user cancelled image capture             toast.maketext(getapplicationcontext(),                     "user cancelled image capture", toast.length_short)                     .show();          } else {             // failed capture image             toast.maketext(getapplicationcontext(),                     "sorry! failed capture image", toast.length_short)                     .show();         }      } }  private void launchuploadactivity(boolean isimage){     intent = new intent(mainactivity.this, uploadactivity.class);     i.putextra("filepath", fileuri.getpath());     i.putextra("isimage", isimage);     startactivity(i); }  /**  * ------------ helper methods ----------------------   * */   public uri getoutputmediafileuri(int type) {     return uri.fromfile(getoutputmediafile(type)); }   private static file getoutputmediafile(int type) {      // external sdcard location     file mediastoragedir = new file(             environment                   .getexternalstoragepublicdirectory(environment.directory_pictures),             config.image_directory_name);      // create storage directory if not exist     if (!mediastoragedir.exists()) {         if (!mediastoragedir.mkdirs()) {             log.d(tag, "oops! failed create "                     + config.image_directory_name + " directory");             return null;         }     }      // create media file name     string timestamp = new simpledateformat("yyyymmdd_hhmmss",             locale.getdefault()).format(new date());     file mediafile;         mediafile = new file(mediastoragedir.getpath() + file.separator                 + "img_" + timestamp + ".jpg");       return mediafile; }

note: got code androidhive

ok think understand problem. understand code check this:

what sharedpreferences?

show image view file path in android?

create imageviews dynamically inside loop

last edit: add commit() solve problem

what going try save file paths in arraylist , save array in sharedpreferences:

layout_example.xml <-- create layout on xml add imageviews inside

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_margintop="5dp"     android:padding="5dp">       <linearlayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical"         android:id="@+id/mylinearlayout"></linearlayout> </relativelayout>
