You can do it without using custom style or inflating the custom view like below code.

您可以不使用自定义样式或像下面的代码那样对自定义视图进行充气。

public void createDialog() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Do you want to exit from app");
    builder.setCancelable(false);
    builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });

    builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(ViewPagerStyle1Activity.this,
                    "You exit from app", Toast.LENGTH_LONG).show();

        }
    });

    AlertDialog alert = builder.create();
    alert.show();
    TextView messageText = (TextView) alert
            .findViewById(android.R.id.message);
    messageText.setBackgroundColor(Color.RED);
    Button nbutton = alert.getButton(DialogInterface.BUTTON_NEGATIVE);
    nbutton.setBackgroundColor(Color.MAGENTA);
    Button pbutton = alert.getButton(DialogInterface.BUTTON_POSITIVE);
    pbutton.setBackgroundColor(Color.YELLOW);
}
