Show one progress dialog only at a time in android

Question

I wonder android support multiple dialog? Since when I first open the dialog. I allow user to click cancel, that will open one more dialog to confirm whether the user want to exit , the problem is if the user do not want to exit, the original dialog will disappear, how to fix the problem? Thanks

public static ProgressDialog showProgressDialog(final Context ctx, boolean isCancelable) {
    ProgressDialog dialog =  new ProgressDialog(ctx);
    dialog.setCancelable(false);
    dialog.setTitle(ctx.getResources().getString(R.string.system_info));
    dialog.setMessage(ctx.getResources().getString(R.string.downloading));
    dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    dialog.setProgress(0);

    if (isCancelable){
        dialog.setButton(DialogInterface.BUTTON_NEGATIVE, ctx.getResources().getString(R.string.cancel), new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                AlertDialog.Builder builder = new Builder(ctx);
                builder.setMessage(R.string.cancel_offline_mode);
                builder.setTitle(R.string.system_info);
                builder.setPositiveButton(ctx.getResources().getString(R.string.confirm), new OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.dismiss();
                    }
                });
                builder.setNegativeButton(ctx.getResources().getString(R.string.cancel), null);
                builder.create().show();
            }
        });
    }
    return dialog;
}

Update:

Here is what I would expected:

1. The first dialog showing the download progress (eg. Downloaded 60% etc..)
2. At the first dialog there is a cancel button, if click on it show the second dialog
3. The second dialog ask whether confirm to cancel download
4. If confirm, do cancel()...
5. If not , return to the first dialog and show the percentage

Thanks

Try this

public void showProgressDialog(final Context ctx, boolean isCancelable) {
        ProgressDialog dialog =  new ProgressDialog(ctx);
        dialog.setCancelable(false);
        dialog.setTitle("Title dialog");
        dialog.setMessage("downloading");
        dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        dialog.setProgress(0);

        if(isCancelable)
        {
            dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                   showDialog2(ctx);
                }

            });
        }
        dialog.show();
    }

    private void showDialog2(final Context ctx) {
         AlertDialog.Builder builder = new Builder(ctx);
           builder.setMessage("cancel");
           builder.setTitle("dialog title");
           builder.setPositiveButton("cancel", new OnClickListener() {
               @Override
               public void onClick(DialogInterface dialog, int which) {
                   showProgressDialog(ctx, false);
                   dialog.dismiss();
               }
           });
           builder.setNegativeButton("confirm", null);
           builder.create().show();                 
    }

By dismissing second dialog you have to call first dialog by yourself and send any result data if you need.
