推荐答案

主页按钮：

=>您不能覆盖​​的home键的行为。

=> You can't override the behaviour of home button.

返回按钮：

=>为了捕获或覆盖默认后退按钮preSS在安卓以下的onkeydown方法可以通过活动来实现。

=> In order to capture or override the default back button press in Android the following onKeyDown method can be implemented by the Activity.

 @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
            moveTaskToBack(true);
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
