    <p>I have been reading up about threads in my java book and I wanted to try making updates with two consecutive threads at the same time.</p> <p>OF course though threads can't update the UI. I have used handlers a little bit but only by passing messengers from one class to another to capture location from a service to an activity.</p> <p>But this must be simpler than that.</p> <p>I assume I should use AsyncTask but i want to count 1-10 in each field and I don't want to keep dipping in and out of the asynctask class.</p> <p>Any pointers appreciated</p> <p>Stephen</p> <p><em>UPDATE</em></p> <p>So I did a little more experimenting. I wrote a handler method to handle any messages sent to it. It checks which field it should be updating and then performs a setText on said field. Here is the code</p> <pre><code>Handler myHandler = new Handler(){ public void handleMessage(Message msg){ msg = Message.obtain(); Bundle bundle = msg.getData(); String fieldName = bundle.getString("fieldName"); int count = bundle.getInt("count"); if(fieldName=="text1"){ text1.setText(count); }else{ text2.setText(count); } } }; </code></pre> <p>I then have some code in the onCreate of my activity which launches two threads and each thread passes a messages with my int count to the handler. It also passes in a TextView name so my handler knows which textview it should be updating. Here is the code...</p> <pre><code>public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); text1 = (TextView)findViewById(R.id.text1); text2 = (TextView)findViewById(R.id.text2); new Thread(){ public void run(){ for(int i=1;i&lt;10;i++){ message = Message.obtain(myHandler); Bundle bundle = new Bundle(); bundle.putCharSequence("fieldName", "text1"); message.setData(bundle); myHandler.sendMessageDelayed(message, 1000); } } }.start(); new Thread(){ public void run(){ for(int i=1;i&lt;10;i++){ message = Message.obtain(myHandler); Bundle bundle = new Bundle(); bundle.putCharSequence("fieldName", "text2"); message.setData(bundle); myHandler.sendMessageDelayed(message, 1000); } } }.start(); } </code></pre> <p>But I am getting an error on the setText</p> <p>05-17 17:13:00.013: ERROR/AndroidRuntime(966): android.content.res.Resources$NotFoundException: String resource ID #0x0</p> <p>Any ideas?</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.
