推荐答案

AlertDialog 适合您的需求，并且易于实施.

AlertDialog suits your needs, and simple to implement.

   AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
            builder.setCancelable(true);
            builder.setTitle("Title");
            builder.setMessage("Message");
            builder.setPositiveButton("Confirm",
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                        }
                    });
            builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                }
            });

            AlertDialog dialog = builder.create();
            dialog.show();
