TextView：如何在TextView中选择文本时避免显示操作菜单？

Question

我有一个可选的TextView，并且我想防止在选择文本时显示操作菜单。

我实现了此代码，但仍显示操作菜单。

   tv.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            // Return true to ensure the yourTextView is still selectable
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            // Remove all action items to provide an actionmode-less selection
            menu.clear();
            return false;
        }

        @Override
        public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) {
            return false;
        }

        @Override
        public void onDestroyActionMode(ActionMode actionMode) {

        }
    });

如何永久删除？

我想，最后写了下面的代码：

    tv.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            removeActionBar(getWindow().getDecorView());
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            return false;
        }

        @Override
        public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem) {
            return false;
        }

        @Override
        public void onDestroyActionMode(ActionMode actionMode) {

        }
    });

    private void removeActionBar(View v) {
            ViewGroup viewgroup = (ViewGroup) v;

            for (int i = 0; i < viewgroup.getChildCount(); i++) {
                    View v1=viewgroup.getChildAt(i);
                    if ( v1 instanceof ViewGroup )
                            removeActionBar(v1);
                    if ( v1 instanceof ActionBarContextView ) {
                            viewgroup.removeView(v1);
                    }
            }
    }
