    <p>I am trying to find a way to call a MessageBox from inside a thread. But every piece of code/example I've found didn't work. Can someone elaborate a solution/example with the easiest and most simple way with the fewest lines of code as possible?</p> <p>This is my code so far:</p> <pre><code>public class MainActivity extends Activity { void MessageBox(String msg){ AlertDialog deleteAlert = new AlertDialog.Builder(this).create(); deleteAlert.setTitle("This is the title"); deleteAlert.setMessage(msg); deleteAlert.show(); } Button b1; TextView tv1; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); b1 = (Button) findViewById(R.id.button1); tv1 = (TextView) findViewById(R.id.editText1); b1.setOnClickListener(new OnClickListener(){ public void onClick(View arg0) { MyRunnable myRunnable = new MyRunnable(); Thread myThread = new Thread(myRunnable); myThread.setDaemon(true); myThread.start(); } }); MainActivity.this.runOnUiThread(new Runnable() { public void run() { MessageBox("This is a message"); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.activity_main, menu); return true; } } class MyRunnable implements Runnable{ Socket Client; public void run() { try { Client = new Socket("192.168.1.20", 3333); //MessageBox } catch (UnknownHostException e) { //MessageBox } catch (IOException e) { //MessageBox } } } </code></pre>

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.
