    <p>I have an application that loads a dialog with some images specified in the dialog's XML layout. I've read a lot about using images in Android and being careful with the VM budget so I believe that any handling of images with the potential to take up a decent amount of memory should be handled off of the main thread. With that said I was wondering if it is wise to load an entire layout off of the UI thread using an ASyncTask. I have a working code but I couldn't find out if this was good practice through some Google searches. Here is the code below.</p> <p>This is the case statement that triggers when the user presses a button to load the dialog.</p> <pre><code>case R.id.showDialog: vibrator.vibrate(vibrateMilis); mDialog = new Dialog(getActivity(), R.style.CustomDialog); new LoadLayout().execute(""); break; </code></pre> <p>And here is the ASyncTask</p> <pre><code>private class LoadLayout extends AsyncTask&lt;String, Void, String&gt; { ProgressDialog progressDialog; @Override protected String doInBackground(String... params) { mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE); mDialog.setContentView(R.layout.dialog_layout); mDialog.setCancelable(true); return null; } @Override protected void onPostExecute(String result) { progressDialog.cancel(); mDialog.show(); } @Override protected void onPreExecute() { progressDialog = new ProgressDialog( getActivity()); progressDialog.setMessage("Loading..."); progressDialog.setCancelable(false); progressDialog.show(); } @Override protected void onProgressUpdate(Void... values) { // Do nothing } } </code></pre> <p>So this code works but the question I have is this. Is this considered good practice? It seems a bit hacky for my taste. I didn't come across this with multiple Google searches so that's why I'm a bit concerned. I mean if it was good practice it would've been documented somewhere right?</p> <p>Thanks for any input.</p>

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.
