Dialog dialog = new Dialog(context)
dialog.setCanceledOnTouchOutside(true); 
//use this to dismiss the dialog on outside click of dialog

dialog.setCanceledOnTouchOutside(false);
//use this for not to dismiss the dialog on outside click of dialog.

我也面临着同样的问题。为了处理它，我设置了一个对话框的OntouchListener，在里面什么都不做。但旋转屏幕时对话框也会消失。为了解决这个问题，我设置了一个变量来告诉我对话框是否正常解散。然后我设置了一个OnDismissListener到我的对话框，在里面我检查变量。如果对话框正常解散，我什么都不做，否则我再次运行对话框(并将他的状态设置为在我的情况下解散时)。

builder.setCancelable(假);

Mensaje(视图v){

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("¿Quieres ir a el Menú principal?");
    builder.setMessage("Al presionar SI iras a el menú y saldras de la materia.");
    builder.setPositiveButton("SI", null);
    builder.setNegativeButton("NO", null);
    builder.setCancelable(false);
    builder.show();
}

对我来说有用的是创建DialogFragment并将其设置为不可取消:

dialog.setCancelable(false);

Dialog dialog = new Dialog(context)
dialog.setCanceledOnTouchOutside(true); 
//use this to dismiss the dialog on outside click of dialog

dialog.setCanceledOnTouchOutside(false);
//use this for not to dismiss the dialog on outside click of dialog.

dialog.setCancelable(false);
//used to prevent the dismiss of dialog on backpress of that activity

dialog.setCancelable(true);
//used to dismiss the dialog on onbackpressed of that activity

以下是我的解决方案:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select The Difficulty Level");
builder.setCancelable(false);
