Hello,

I prepared AsyncTask with AlertDialog in which are Yes / No button. I need return 1 for Yes and 0 for No.
I dont understand AsyncTask fully. What hate to add to wait for click? Current state doesnt wait :/

CODE CLASS:

class MyTask extends AsyncTask<Void,Integer,Integer> {
    TextView ozn_=null;
    AlertDialog dialog=null;
    AlertDialog.Builder builder=null;
    ImageView icon=null;
    int ret=0;

    public int getRetValue(){
        return ret;
    }

    public MyTask(int a){
        ret=a;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        ozn_ = new TextView(LoginActivity.this);
        AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
        ImageView icon = new ImageView(LoginActivity.this);
        icon.setBackgroundResource(R.drawable.warn);
        builder.setMessage("oznam");
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(set_dp(60), set_dp(60));
        icon.setLayoutParams(params);
        ozn_.setGravity(Gravity.LEFT);
        LinearLayout l1 = new LinearLayout(LoginActivity.this);
        l1.setPadding(set_dp(12), set_dp(12), set_dp(12), set_dp(20));
        l1.setOrientation(LinearLayout.HORIZONTAL);
        l1.setGravity(Gravity.CENTER_VERTICAL);
        ozn_.setPadding(set_dp(12), 0, 0, 0);
        l1.addView(icon);
        l1.addView(ozn_);
        builder.setView(l1);

        builder.setPositiveButton("Áno", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                publishProgress(11);                   //somewhere  here is needed control of wait
                getResources().notifyAll();
                dialog.dismiss();
            }
        });
        builder.setNegativeButton("Nie", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                publishProgress(222);             //somewhere  here is needed control of wait
                getResources().notifyAll();
                dialog.dismiss();
            }
        });

        dialog = builder.create();
        dialog.setOnShowListener(new DialogInterface.OnShowListener() {
            @Override
            public void onShow(DialogInterface arg0) {
                dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(0xff00b300);
                dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(0xffd56300);
            }
        });
        dialog.setCancelable(false);                 //backbutton
        dialog.setCanceledOnTouchOutside(false);     //klick outside dialog
        dialog.show();
    }

    @Override
    protected Integer doInBackground(Void... rets) {
            return ret;
    }

    @Override
    protected void onProgressUpdate(Integer... values) {
        super.onProgressUpdate();
        ret++;
    }

    @Override
    protected void onPostExecute(Integer aVoid) {
        super.onPostExecute(aVoid);
        Toast.makeText(LoginActivity.this, "post"+ret, Toast.LENGTH_SHORT).show();
    }
}

and CODE IN ACTIVITY:
*****************************
int a=654;
MyTask task=new MyTask(a);
task.execute();
a=task.getRetValue();

SOLVED!

This solution is waiting on click event really and return value.

     private boolean resultValue;
  public boolean getDialogValueBack(Context context)
 {
    final Handler handler = new Handler()
{
    @Override
    public void handleMessage(Message mesg)
    {
        throw new RuntimeException();
    } 
};

AlertDialog.Builder alert = new AlertDialog.Builder(context);
alert.setTitle("Title");
alert.setMessage("Message");
alert.setPositiveButton("Return True", new DialogInterface.OnClickListener()
{
    public void onClick(DialogInterface dialog, int id)
    {
        resultValue = true;
        handler.sendMessage(handler.obtainMessage());
    }
});
alert.setNegativeButton("Return False", new DialogInterface.OnClickListener()
{
    public void onClick(DialogInterface dialog, int id)
    {
        resultValue = false;
        handler.sendMessage(handler.obtainMessage());
    }
});
alert.show();

try{ Looper.loop(); }
catch(RuntimeException e){}

return resultValue;

}
