在TextView选择ActionMode中删除默认的CAB项目 [英] Remove default CAB items in TextView selection ActionMode

问题描述

当用户从 TextView 元素中选择一些文本时，我试图从CAB中删除默认项，例如复制和全选。

I'm trying to remove default items, such as "Copy" and "Select All", from the CAB when the user selects some text from a TextView element.

我已使用此代码覆盖了默认操作，但增加新菜单资源并不会删除默认项。

I've overridden the default action using this code, but inflating a new menu resource doesn't remove default items.

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

        mode.setTitle("Test");
        mode.getMenuInflater().inflate(R.menu.new_menu_selection, menu);
        return true;
    }

    @Override
    public boolean onPrepareActionMode(ActionMode mode, Menu menu) {

        return false;
    }

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

    @Override
    public void onDestroyActionMode(ActionMode mode) {

    }
});

有解决方案吗？

推荐答案

要删除默认项目，可以在添加新菜单之前调用 menu.clear（）：

To remove the default items you can call menu.clear() before inflate the new menu:

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

        menu.clear();

        mode.setTitle("Test");
        mode.getMenuInflater().inflate(R.menu.new_menu_selection, menu);
        return true;
    }

    @Override
    public boolean onPrepareActionMode(ActionMode mode, Menu menu) {

        return false;
    }

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

    @Override
    public void onDestroyActionMode(ActionMode mode) {

    }
});
