Answer 1

将取消设为

dialog.setCancelable(false);


dialog.setOnKeyListener(new Dialog.OnKeyListener() {
        @Override
        public boolean onKey(DialogInterface dialogs, int keyCode,
                             KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_HOME) {
                 //what should i do
                 return true;
            }
            return false;
        }
    });

如果您的上述代码在您的服务中有效，则只需返回true即可。

dialog.setOnKeyListener(new Dialog.OnKeyListener() {
            @Override
            public boolean onKey(DialogInterface dialogs, int keyCode,
                                 KeyEvent event) {

                if (keyCode == KeyEvent.KEYCODE_BACK) {
                     return true;
                }
                if (keyCode == KeyEvent.KEYCODE_HOME) {
                     return true;
                }
                return false;
            }
        });

注意： 返回true将表明系统您将处理更多事件，并且无法进一步转发event
