推荐答案

这个尝试，它可以解决你的问题：

Try with this, it may solve your problem:

@Override

    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if ((keyCode == KeyEvent.KEYCODE_HOME)) {
            System.out.println("KEYCODE_HOME");
            return true;
        }
        if ((keyCode == KeyEvent.KEYCODE_BACK)) {
            System.out.println("KEYCODE_BACK");
            return true;
        }
        if ((keyCode == KeyEvent.KEYCODE_MENU)) {
            System.out.println("KEYCODE_MENU");
            return true;
        }
