java - UnsupportedOperationException : Use MenuItemCompat. setOnActionExpandListener()

Question

我之前成功创建了一个搜索项并调用了 .setOnActionExpandListener()，但是现在我收到了一个 UnsupportedOperationException 并且不知道如何解决。这可能与我的 gradle 中 compileSDKVersion、targetSDKVersion 之间的冲突有关，但我不确定。我读过其他 SO 帖子，表明它实际上是 Google 支持库 中的错误，并且已修复，但我无法确认。我最近更新了我正在使用的 Android 支持库，这也可能是导致该问题的原因，请参阅下面的详细信息:

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_search, menu);
    // Retrieve the SearchView and plug it into SearchManager

    SupportMenuItem searchItem = (SupportMenuItem) menu.findItem(R.id.search);

    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);


    searchItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
        @Override
        public boolean onMenuItemActionExpand(MenuItem menuItem) {
            Toast.makeText(getApplicationContext(), "OPEN", Toast.LENGTH_LONG).show();

            return false;
        }

        @Override
        public boolean onMenuItemActionCollapse(MenuItem menuItem) {
            Toast.makeText(getApplicationContext(), "Close", Toast.LENGTH_LONG).show();
            finish();
            return false;
        }
    });

异常:

错误日志很好地描述了异常的原因:

This is not supported, use MenuItemCompat.setOnActionExpandListener()

这意味着，而不是:

searchItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {...});

你应该这样做:

MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() {...})
