问题描述

我在禁用菜单按钮有问题，我不想要的菜单按钮，可以启用，停用通过返回假在上prepareOptionsMenu 的功能，但它隐藏了所有行动项目在我的行动吧，这样如何禁用不影响我的动作条菜单按钮？

I have a problem in disabling menu button , I dont want the menu button to be enable , I disable is by returning false in onPrepareOptionsMenu function , but it hides all action items in my action bar, so How to disable menu button without affecting my actionbar?

推荐答案

硬件菜单按钮不被在prepareOptionsMenu控制（）。一般来说，它是不是很好的做法，改变硬件按钮的行为，因为用户所期望的行为以一定的方式（我认为这是扩大溢出菜单）。

Hardware menu button is not controlled by onPrepareOptionsMenu(). Generally speaking, it is not good practice to change the behavior of hardware buttons because users expect it to behave a certain way (which I believe is to expand the overflow menu).

如果你绝对要禁用它，你可以听它是pssed我们的活动像这样$ P $：

If you absolutely have to disable it, you could listen for it to be pressed in our Activities like this:

public boolean dispatchKeyEvent(KeyEvent event) {
    final int keycode = event.getKeyCode();
    final int action = event.getAction();
    if (keycode == KeyEvent.KEYCODE_MENU && action == KeyEvent.ACTION_UP) {
        return true; // consume the key press
    }
    return super.dispatchKeyEvent(event);
}
