Devices with Android + MIUI and setCustomSelectionActionModeCallback

问题

I'm trying to create custom selection menu but it does not work on a device with rom MIUI and Android 6. The result is common menu with "copy" and "select all" items. On other devices and simulators under clean Android it works just fine. The code

       textViewTop.setCustomSelectionActionModeCallback(new android.view.ActionMode.Callback() {
        @Override
        public boolean onCreateActionMode(android.view.ActionMode mode, Menu menu) {

            Log.d(LOG_TAG, "onCreateActionMode");

            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            Log.d(LOG_TAG, "onPrepareActionMode");
            menu.clear();

            int quote_quick = R.drawable.ic_desktop_mac_black_24dp;
            int quote_add = R.drawable.ic_computer_black_24dp;
            int copy = R.drawable.ic_devices_other_black_24dp;

            menu.add(Menu.NONE, QUOTE_START, 3, "").setIcon(quote_quick).setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_ALWAYS);
            menu.add(Menu.NONE, QUOTE_ADD, 2, "").setIcon(quote_add).setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_ALWAYS);
            menu.add(Menu.NONE, CUSTOM_COPY, 1, "").setIcon(copy).setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_ALWAYS);
            return false;
        }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            return false;
        }

        @Override
        public void onDestroyActionMode(ActionMode mode) {

        }
    });

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:

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
    }
}
