If you user the Looper and another handler to your class F, it would
work.
Code marked with //NEW
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 Handler mHandler;
public void run()
{
Looper.prepare(); //NEW
final CharSequence[] items = {"Ottimo", "Buono",
"Sufficiente","Insufficiente"};
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();
dialog.cancel();
statusField.setText(items[item]);
Message m = new Message(); //NEW
m.what = 1; //NEW, any id is fine,
a const would be better :)
m.arg1 = item; //NEW
mHandler.sendMessage(m); //NEW
}
});
AlertDialog alert = builder.create();
alert.requestWindowFeature
(Window.FEATURE_NO_TITLE);
alert.getWindow().setFlags
(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
alert.show();
}});
mHandler = new Handler() { //NEW
public void handleMessage(Message msg) {
switch (msg.what) {
case 1:
voto = items[msg.arg1].toString();
Log.d("Class F" , voto);
break;
default:
super.handleMessage(msg);
}
}
};
Looper.loop(); // NEW
}
