    <p>I've got to set an autocompletion for my application.</p> <p>I've already understood the AutoCompleteTextView operation, but I'd like to dynamically modify the <code>String[]</code> used by android autocompletion.</p> <p>What I wanna do : call a PHP page which will give me a <code>String[]</code> that I'll use in my AutoCompleteTextView, but i wanna do that ONLY if a key was pressed at least 500 milliseconds after the last one.</p> <hr> <h1>EDIT :</h1> <p>Okay, I was wrong. I want to have my asynctask running if NO KEY is pressed in the 500 milliseconds after the last press (you know, avoiding overcharging our servers by calling a request on every character typed in.)</p> <hr> <p>Here is how I think I'll do :</p> <pre><code>zipBox.setAdapter(myAdapter); //zipBox is an AutoCompleteTextView zipBox.addTextChangedListener(new TextWatcher(){ @Override public void onTextChanged(CharSequence s, int start, int before, int count){ d = new Date(); GetAutocompletion ac = new GetAutocompletion(); ac.execute(zipBox.getText().toString()); } // Other methods to implement }); private class GetAutocompletion extends AsyncTask&lt;String, String, String&gt;{ @Override protected String doInBackground(String... params){ //adapter.notifyDataSetChanged(); try{ wait(500); } catch(InterruptedException e){} Date d1 = new Date(); if(d1.getTime() - d.getTime() &gt; 500){ String res = ""; try{ URLConnection conn = new URL("myUrl.php?term=" + params[0]).openConnection(); InputStream in = conn.getInputStream(); Scanner s = new Scanner(in).useDelimiter("\\A"); while (s.hasNext()) res += s.next(); s.close(); in.close(); } catch(Exception e){ Log.d("eduine", "error during autocompletion receive"); } return json; } else return null; } @Override protected void onPostExecute(String result){ super.onPostExecute(result); Log.d("eduine", "json result : " + result); } } </code></pre> <p>What do you think? Is there anyway I could use Timer class?</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.
