    <p>My app sets up a list of football team names, and on clicking a textview, the corresponding class is called in a the intent method.</p> <p>The classes that are called load an xml layout file which is approx 200kb. I would like to implement a progress/loading icon whilst the xml file loads in the background.</p> <p>I've looked on this site and read about ASynchTask but I don't know what code I need to write in the doInBackground() method.</p> <p>Here is my class:</p> <p>I have an array of textviews that get initialised, and an array of classnames assigned to each textview when clicked.</p> <p>Can anybody help me? I'm a noobie.</p> <p>As an alternative, is there a way of loading all these classes in the background when the user first clicks on the app?</p> <p>public class Transfers extends Activity {</p> <pre><code>public final int[] teams = { R.id.ars, R.id.ast, R.id.bir, R.id.bla, R.id.blp, R.id.bol, R.id.che, R.id.eve, R.id.ful, R.id.hul, R.id.lee, R.id.liv, R.id.mid, R.id.mnc, R.id.mnu, R.id.nor, R.id.nwu, R.id.por, R.id.qpr, R.id.sto, R.id.sun, R.id.swa, R.id.tot, R.id.wes, R.id.wig, R.id.wol }; public final String[] teamnames = { "ars", "ast", "bir", "bla", "blp", "bol", "che", "eve", "ful", "hul", "lee", "liv", "mid", "mnc", "mnu", "nor", "nwu", "por", "qpr", "sto", "sun", "swa", "tot", "wes", "wig", "wol" }; TextView tv; Class classname; String prefix = "ttj.android.ft.teams."; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.m_transfers); for (int i = 0; i &lt; teams.length; i++) { final int j = i; tv = (TextView) findViewById(teams[i]); tv.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { try { classname = Class.forName(prefix + teamnames[j]); Intent open = new Intent(Transfers.this, classname); startActivity(open); } catch (ClassNotFoundException e) { e.printStackTrace(); } } }); } ; } </code></pre>

    3. COwhen you are starting to call your next activity, just display the ProgressDialog, do the background process, and dismiss it in handler, very easy.

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.
