我在我的应用程序，我已经测试工作在Android 4.0的一个选项菜单。 在code为如下图所示：

I have a options menu in my application which I have tested to work on Android 4.0. The code is as shown below:

@Override
    public boolean onCreateOptionsMenu(Menu menu)
    {
        MenuInflater menuInflater = getMenuInflater();
        menuInflater.inflate(R.layout.menu, menu);
        return true;
    }

    /**
     * Event Handling for Individual menu item selected
     * Identify single menu item by it's id
     * */
    @Override
    public boolean onOptionsItemSelected(MenuItem item)
    {

        switch (item.getItemId())
        {

        case R.id.menu_share:

             //code to do something when chosen etc


            return true;

        default:
            return super.onOptionsItemSelected(item);
        }
    } 

现在，如果我运行在Android 4.4在同一code（我测试了摩托G），选项菜单没有出现。

Now if I run the same code on Android 4.4 (I tested on Moto G), the options menu is not appearing.

知不知道我必须做的，因为有关联的设备？

Any idea what I must do since there is no Android menu button on the device?

推荐答案

您的活动类里面将这个如果要强制应用程序以显示操作溢出：

Put this inside your activity class if you want to Force to the Application to show the Action Overflow:

    try {
        ViewConfiguration config = ViewConfiguration.get(this);
        Field menuKeyField = ViewConfiguration.class
                .getDeclaredField("sHasPermanentMenuKey");
        if (menuKeyField != null) {
            menuKeyField.setAccessible(true);
            menuKeyField.setBoolean(config, false);
        }
    } catch (Exception ex) {
        // Ignore
    }
