    According to https://developer.android.com/guide/topics/ui/menus#CAB you need to create menu in onCreateActionMode.

    I made it like this (in kotlin):

        val actionModeCallbackA = object : ActionMode.Callback {
    override fun onActionItemClicked(mode: ActionMode?, p1: MenuItem?): Boolean {
        Log.wtf("ACTION MODE", "onActionItemClicked")
        actionModeB = startActionMode(actionModeCallbackB)
        return true
    }

    override fun onCreateActionMode(mode: ActionMode?, menu: Menu?): Boolean {
        Log.wtf("ACTION MODE", "onCreateActionMode")
        val inflater = mode?.getMenuInflater()
        inflater?.inflate(R.menu.context_menu, menu)
        return true
    }

    override fun onPrepareActionMode(p0: ActionMode?, p1: Menu?): Boolean {
        Log.wtf("ACTION MODE", "onPrepareActionMode")
        return false
    }

    override fun onDestroyActionMode(p0: ActionMode?) {
        Log.wtf("ACTION MODE", "onDestroyActionMode")
            actionModeA = null
    }
}

    Just some thoughts. What if you take menu item onCreateOptionsMenu and change it.

    Like this:

    public boolean onCreateOptionsMenu(final Menu menu) {
  getSupportMenuInflater().inflate(R.menu.main, menu);
  new Handler().post( -> {
      final View menuItemView = findViewById(R.id.menu_action_item);
      ...
  }
}

    So I figured out a workaround, but it makes sense only if you absolutely need it to work on MIUI devices. It's generally a little awkward:

    I noticed that the Wikipedia app has custom actions working on a Xiaomi device, and after looking through the code I found out it works fine when the texts is selected in a WebView. You can basically use a WebView and override onActionModeStarted in your Activity

    Acivity:

    String html = "<!DOCTYPE html>\n" +
        "<html>\n" +
        "<head>\n" +
        "</head>\n" +
        "<body>\n" +
        "\n" +
        "<h1>WebView text</h1>\n" +
        "\n" +
        "</body>\n" +
        "</html>\n";

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

    WebView webView = findViewById(R.id.web_view);
    webView.setWebViewClient(new WebViewClient());
    webView.loadData(html, "text/html", "UTF-8");
}

@Override
public void onActionModeStarted(ActionMode mode) {
    super.onActionModeStarted(mode);
        Menu menu = mode.getMenu();
        menu.clear();
        mode.getMenuInflater().inflate(R.menu.menu_text_select, menu);
}

    Menu: 

    <item android:id="@+id/id1"
      android:title="miui"
      app:showAsAction="ifRoom" />

<item android:id="@+id/id2"
      android:title="has"
      app:showAsAction="ifRoom" />

<item android:id="@+id/id3"
      android:title="bugs"
      app:showAsAction="ifRoom" />

<item android:id="@+id/id4"
    android:title="D:"
    app:showAsAction="ifRoom" />

    Result:

    I had similar problem, maybe my solution would help someone. I had to make a view composed of several horizontal neighboring EditText's, and add ability to paste text to them (one letter of text to one editText) I used ActionMode.Callback's approach and it was working fine, except Xiaomi devices. The solution for Xiaomi devices was using OnLongClickListener on edit texts and create PopupMenu on long click:

    editText.setOnLongClickListener(v -> {
    PopupMenu menu = new PopupMenu(context,v);
    MenuInflater inflater = menu.getMenuInflater();
    inflater.inflate(R.menu.paste_menu_item, menu.getMenu());
    menu.setOnMenuItemClickListener(item -> {
       pasteText();//some custom function to handle selected action
       return false;
    });
    menu.show();
    return true;
});
