If you change your code in a few places, it should work. (It worked for me :))
I have demarked the code changes with //======== START==== and //======= END ==== public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Handler handler=new Handler(); //====== START ==== // 1. I assume you have a TextView defined in your layout.main file. // 2. Make sure you have android:id set e.g. <TextView android:id="@+id/tview" TextView statusField = (TextView) findViewById(R.id.tview); //====== END ====== F thread=new F(this,statusField,handler); thread.start(); } } class F extends Thread{ Context context; TextView statusField; Handler handler; String voto; F(Context context,TextView statusField,Handler handler) {this.context=context;this.statusField=statusField;this.handler=handler;} public void run() { final CharSequence[] items = {"Ottimo", "Buono", "Sufficiente","Insufficiente"}; String voto=""; handler.post(new Runnable(){public void run(){ AlertDialog.Builder builder = new AlertDialog.Builder(context); builder.setTitle("Pick a color"); builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int item) { Toast.makeText (context.getApplicationContext(), items [item], Toast.LENGTH_SHORT).show(); //======== START ======= dialog.cancel(); statusField.setText(items[item]); //========= END ========= } }); AlertDialog alert = builder.create(); alert.show(); }}); //statusField.setText(voto); //REMOVE } } Hope this helps, Balwinder Kaur Open Source Development Center ·T· · ·Mobile· stick together The views, opinions and statements in this email are those of the author solely in their individual capacity, and do not necessarily represent those of T-Mobile USA, Inc.
