Android ActionMode不适用于所有Android版本

Question

我的下面的代码不适用于Android 4.x，我搜索更多有关该问题的解决方案，但我无法解决此问题

private void makeSelectable(ViewGroup viewGroup, final int mPosition, final int mIndexPosition) {
        for (int i = 0; i < viewGroup.getChildCount(); i++) {
            final View child = viewGroup.getChildAt(i);
            if (child instanceof ViewGroup) {
                makeSelectable((ViewGroup) child, mPosition, mIndexPosition);
            } else if (child instanceof TextView) {
                Log.e("FOUND ", " TEXTVIEW " + i);
                ((TextView) child).setGravity(Gravity.RIGHT);
                ((TextView) child).setTextIsSelectable(true);
                ((TextView) child).setTextSize(TypedValue.COMPLEX_UNIT_SP, textSize == 0 ? 14 : textSize);

                child.setFocusable(true);
                child.setFocusableInTouchMode(true);

                ((TextView) child).setMovementMethod(LinkMovementMethod.getInstance());
                ((TextView) child).setCustomSelectionActionModeCallback(new ActionMode.Callback() {
                    ...
                });
            }
        }
    }
