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,
