new AlertDialog.Builder(MainActivity.this)
            .setTitle("dialog")
            .setMessage("三者的区别")
            .setPositiveButton("positive", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {

                }
            })
            .setNegativeButton("negative", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {

                }
            })
            .setNeutralButton("neutral", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {

                }
            })
            .show();
