android - 无法设置 OnActionExpandListener : This is not supported, 使用 MenuItemCompat.setOnActionExpandListener()

Question

这听起来像是一个重复的问题，但事实并非如此。

我正在尝试设置 OnActionExpandListener到我的搜索菜单项:

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_country_picker, menu);
    MenuItem menuItem = menu.findItem(R.id.search);
    menuItem.setOnActionExpandListener(this);
    //more code
    return true;
}

当我运行它时，我得到了这个异常:

java.lang.UnsupportedOperationException: This is not supported, use MenuItemCompat.setOnActionExpandListener()
                                                                            at android.support.v7.view.menu.MenuItemImpl.setOnActionExpandListener(MenuItemImpl.java:743)

很酷，让我们使用 MenuItemCompat.setOnActionExpandListener()那么!

这是我替换 menuItem.setOnActionExpandListener(this); 时得到的结果与 MenuItemCompat.setOnActionExpandListener(menuItem, this); :

简单描述:

尝试使用A:不支持，使用B。

尝试使用B:不支持，使用B。

我的一些可能相关的 build.gradle 配置:

compileSdkVersion 23
buildToolsVersion '25.0.2'

defaultConfig {
    minSdkVersion 21
    targetSdkVersion 23
}

dependencies {
    compile 'com.android.support:support-v4:23.4.0'
    androidTestCompile 'com.android.support:support-annotations:26.0.0-alpha1'
    ...
}

附言:MenuItemCompat.setOnActionExpandListener()已弃用，文档建议使用 MenuItem.setOnActionExpandListener(MenuItem.OnActionExpandListener ，这是我最初尝试的方法，但如您所见，它没有用。

有什么想法吗？

com.android.support:support-annotations:26.0.0-alpha1 已离开 alpha 版本。尝试更新到 com.android.support:support-annotations:26.0.0
