getActionView is deprecated?
提问by Ross Thomas
Today I decide to translate my android app from Java to Kotlin ! :) But I was very surprise when I type this :
今天我决定将我的 android 应用程序从 Java 翻译成 Kotlin！:) 但是当我输入这个时我很惊讶：
val searchItem = menu.findItem(R.id.action_search)
val searchView = MenuItemCompat.getActionView(searchItem) as SearchView
And Android Studio told me : " 'getActionView(MenuItem!):View!' is deprecated. Deprecated in Java "
Android Studio 告诉我：“'getActionView(MenuItem!):View!' 已弃用。在 Java 中已弃用“
So before to ask you the solution I ask to Google what is the solution and I believed I find the solution : "Use getActionView() directly."
所以在问你解决方案之前，我问谷歌什么是解决方案，我相信我找到了解决方案：“直接使用 getActionView()”。
So I modified my code like this :
所以我像这样修改了我的代码：
val searchView = MenuItemCompat.getActionView() as SearchView
But getActionView()is still crossed so I don't understand at all...
但是getActionView()还是被划掉了所以我完全不明白......
I will be very happy if you can help me :) Thank you !
如果你能帮助我，我会很高兴:) 谢谢！

The Javadoc says:
Javadoc 说：
Use getActionView() directly.
直接使用 getActionView()。
Hence, what you should do is:
因此，你应该做的是：
val searchView = searchItem.getActionView() as SearchView

As suggested by egor, you can do like this
正如 egor 所建议的，你可以这样做
getMenuInflater().inflate(R.menu.menu_items, menu);
MenuItem menuItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) menuItem.getActionView();
search(searchView);
return true;

You can use the same as provided on android developerwebsite
您可以使用与android 开发者网站上提供的相同的
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the options menu from XML
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
// Get the SearchView and set the searchable configuration
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
// Assumes current activity is the searchable activity
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default
return true;
}

Use actionViewdirectly in Kotlin, like this:
actionView在 Kotlin 中直接使用，像这样：
override fun onCreateOptionsMenu(menu: Menu?): Boolean {
menuInflater.inflate(R.menu.actions, menu)
val searchItem = menu?.findItem(R.id.action_search)
val searchView = searchItem?.actionView as SearchView
searchView.animate()
// TODO: Configure the search info and add any event listeners...
return super.onCreateOptionsMenu(menu)
}
