    <p>I'm using a photo picker intent to choose an image and write it to an application-private file. Most of my important source code is shown below. Once I press a button and perform the first image selection intent, then it successfully updates the image view. However, once I press the image selection button again (in the same activity), then the image view does NOT update, unless I exit and restart the activity. So I know the image is getting successfully saved, but why would the ImageView in the layout not refresh or update?</p> <pre><code>public void onResume() { super.onResume(); ImageView myImageView = (ImageView)findViewById(R.id.contact_image); if (hasImage) { myImageView.setImageURI(Uri.fromFile(getFileStreamPath(TEMP_PHOTO_FILE))); } } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case PHOTO_PICKED: if (resultCode == RESULT_OK) { if (data != null) { Bundle extras = data.getExtras(); if (extras != null) { hasImage = true; bmp = (Bitmap) extras.get("data"); } } } break; } } private OnClickListener mChooseImage = new OnClickListener() { @Override public void onClick(View v) { try { // Launch picker to choose photo for selected contact Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null); intent.setType("image/*"); intent.putExtra("crop", "true"); intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); intent.putExtra("outputX", ICON_SIZE); intent.putExtra("outputY", ICON_SIZE); intent.putExtra("scale", true); intent.putExtra("return-data", false); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile())); intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString()); startActivityForResult(intent, PHOTO_PICKED); } catch (ActivityNotFoundException e) { // LOG THIS } } }; private File getTempFile() { try { if (!hasImage) { FileOutputStream fos = openFileOutput(TEMP_PHOTO_FILE, MODE_WORLD_WRITEABLE); fos.close(); } return getFileStreamPath(TEMP_PHOTO_FILE); } catch (FileNotFoundException e) { // To be logged later return null; } catch (IOException e) { // To be logged later return null; } } </code></pre> <p>upon activity result, I set the ImageView's image URI to this file.</p> <p>When it first completes, the ImageView changes to reflect this. However, if I attempt to choose the image again (same activity), the ImageView will not update until I exit and re-enter the activity. I'm not sure why this happens, is it because I'm trying to write to the temp.jpg everytime? Or do I need to refresh my layout somehow to reflect changes in the ImageView?</p>

    1. COIs there some code missing? From what you wrote it shouldn't be required to open output streams to the selected image.

    2. COI have added a majority of my source code. I also find that if I just return the value from the intent as a bitmap, then the image view successfully updates. However, I still want to know the source of the problem.

    3. COso is there something I don't know about ImageViews or the image picker intent? something which does not reflect the change until restarting the activity?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
