setCustomSelectionActionModeCallback无法使用我的editText :(

Question

在我的editText上，当我执行setCustomSelectionActionModeCallback（new Callback（）{}）时，从不调用Callback :(我认为edittext上的所有内容都配置得很好，我做

• settextIsSelectable（真）;
• setfocusable（真）;
• setfocusableInTouchMode（真）;
• setlongClickable（真）;

我的editText中有什么可以禁止回调？如何为我的edittext构建自定义上下文菜单？

这是我的代码：

this.setCustomSelectionActionModeCallback(new Callback() {

    @Override
    public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
        Log.e("onPrepareActionMode","onPrepareActionMode");
        return true;
    }

    @Override
    public boolean onCreateActionMode(ActionMode mode, Menu menu) {
        Log.e("onCreateActionMode","onCreateActionMode");
        return true;
    }

    @Override
    public void onDestroyActionMode(ActionMode mode) {
        Log.e("onDestroyActionMode","onDestroyActionMode");
    }

    @Override
    public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
    Log.e("onActionItemClicked","onActionItemClicked");
    return true;
    }

});
