    <p>I currently have a simple list view adapter that holds two rows of text. What I am trying to do next is add the option of displaying a photo that the user took in the list view. I modified my list adapter like so: </p> <pre><code>standardAdapter = new SimpleAdapter(this, list, R.layout.post_layout, new String[] { "time", "post", "image"}, new int[] { R.id.postTimeTextView, R.id.postTextView, R.id.post_imageView}); </code></pre> <p>Then I add it to the hash map as usual and refresh the adapter:</p> <pre><code>// create a new hash map with the text from the post feedPostMap = new HashMap&lt;String, Object&gt;(); feedPostMap.put("time", currentTimePost); feedPostMap.put("post", post); if(photoWasTaken == 1){ feedPostMap.put("image", pictureTaken); } //add map to list list.add(feedPostMap); // refresh the adapter standardAdapter.notifyDataSetChanged(); </code></pre> <p>Lastly, here is the code for activity on result:</p> <pre><code>@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); Log.d(TAG, "ON activity for result- CAMERA"); if (resultCode == Activity.RESULT_OK) { //get and decode the file pictureTaken = BitmapFactory.decodeFile("/sdcard/livefeedrTemp.png"); //Display picture above the text box imageViewShowPictureTaken.setImageBitmap(pictureTaken); displayPhotoLayout.setVisibility(LinearLayout.VISIBLE); //NEW - make photo variable = 1 photoWasTaken = 1; } } </code></pre> <p>However I am running into an issue. The photo, in bitmap form, is not being added to the list view. It just appears as empty white space. Am I doing something wrong here? Secondly, if the user decided not to take a picture, then the image view should not be displayed. I'm not sure how to implement this. Should I create a custom list adapter? </p> <p>Thanks for your help</p>

    3. COWhen you access your picture on the sdcard, you should access it by using this.getExternalStorageDirectory()+pathToImage, and not directly by /sdcard/. You should also check you have permission to access for read/write on the external storage in your manifest.xml,and, if you could provide some error code, or some logcat it could be relevant here, because the process you use seems to be right, but I can't really test the code right now.

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.
