如何在运行时修改 WearableActionDrawer？

Question

我已经为我的 Wear OS 应用程序创建了一个 ActionDrawer，并且想在运行时间更改图标和文本。此代码有效，我的应用程序继续运行没有错误，但我无法再向上滑动 ActionDrawer。此外，当 ActionDrawerMenu 已经打开并且我按下那里的按钮时，它消失了并且我的应用程序 UI 似乎被冻结了。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //Top navigation drawer
    WearableNavigationDrawerView wearableNavigationDrawer = (WearableNavigationDrawerView) findViewById(R.id.top_navigation_drawer);
    wearableNavigationDrawer.setAdapter(new NavigationDrawerAdapter());
    wearableNavigationDrawer.getController().peekDrawer();

    //Bottom action drawer
    WearableActionDrawerView wearableActionDrawer = (WearableActionDrawerView) findViewById(R.id.bottom_action_drawer);
    wearableActionDrawer.getController().peekDrawer();
    wearableActionDrawer.setOnMenuItemClickListener(this);
}

@Override
public boolean onMenuItemClick(MenuItem menuItem) {
    final int itemId = menuItem.getItemId();

    switch(itemId) {
        case R.id.menuItem_pause:
            if(intent == null) {
                menuItem.setIcon(getDrawable(R.drawable.ic_pause));
                menuItem.setTitle(R.string.actionDrawerMenuPause);
            } else {
                menuItem.setIcon(getDrawable(R.drawable.ic_play));
                menuItem.setTitle(R.string.actionDrawerMenuStart);
            }
            invalidateOptionsMenu();
            return true;
    }

    return false;
}

我尝试了一些使用 invalidateOptionsMenu()、onPrepareOptionsMenu() 和 onCreateOptionsMenu() 的解决方案，但对我没有任何效果。我认为这只适用于标准 Android 移动应用程序，但不适用于 Wear OS。那么如何在按下 MenuItem 时更改 WearableActionDrawer-MenuItems 的文本和图标？

Answer 1

我无意中找到了解决方案。只是这一行代码以编程方式实现了菜单。

//Bottom action drawer
WearableActionDrawerView wearableActionDrawer = findViewById(R.id.bottom_action_drawer);
wearableActionDrawer.getController().peekDrawer();
wearableActionDrawer.setOnMenuItemClickListener(this);
getMenuInflater().inflate(R.menu.action_drawer_menu, wearableActionDrawer.getMenu());
