copied!<p>You are searching for AsyncTasks <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="nofollow">http://developer.android.com/reference/android/os/AsyncTask.html</a></p> <p>It's pretty simple: You implement a class with AsyncTask as it's superclass and override the three methods:</p> <p>The <code>onPreExecute()</code>-method should show a <code>ProgressDialog</code></p> <p>The <code>doInBackground(Context... arg0)</code>-method collects the data from the database.</p> <p>The <code>onPostExecute(String result)</code>-method puts the data into the list and closes the <code>ProgressDialog</code></p> <p>In your code you should split your method into two: The first one (let's call it <code>getData()</code>) from the start to <code>db.close();</code> and everything after that in the second method (for example <code>showData()</code>)</p> <p>Then you create a class in your activity like this:</p> <pre><code>protected class LoadDataTask extends AsyncTask<Context, Integer, String> { ProgressDialog myLoadingDialog; @Override protected void onPreExecute() { myLoadingDialog = new ProgressDialog(YourActivity.this); myLoadingDialog.setMessage("Loading"); myLoadingDialog.setIndeterminate(false); myLoadingDialog.setCancelable(false); myLoadingDialog.show(); super.onPreExecute(); } @Override protected String doInBackground(Context... arg0) { getData(); return null; } @Override protected void onPostExecute(String result) { showData(); myLoadingDialog.dismiss(); super.onPostExecute(result); } } </code></pre> <p>Put the variables outside of the methods, which you need in both methods.</p>
