android - 为自定义操作栏项目设置 onClick 事件

Question

当我尝试在自定义 ActionBar 的项目上添加 onClick 事件时，出现以下异常。当我在 ActionBar 中单击 searchiconactionbar 时，我的应用程序崩溃了。我已将方法 onClick() 放入 Activity 中只有。为什么我会收到此错误？是否有任何其他方法可以为自定义 ActionBar 项目设置 onClickListener？

代码-

        LayoutInflater mInflater2 = LayoutInflater.from(this);
        View mCustomView2 = mInflater.inflate(R.layout.actionbar_gip, null);
  searchtext=(EditText)mCustomView2.findViewById(R.id.actionsearchtext);
        searchIcon=(ImageView)mCustomView2.findViewById(R.id.searchiconactionbar);
          getSupportActionBar().setCustomView(R.layout.actionbar_gip);
   public void clickEvent(View v) {
        if (v.getId() == R.id.searchiconactionbar) {
            if (searchtext.getVisibility() == View.GONE)
                expand(searchtext);
            else
                collapse(searchtext);
        }

    }

Answer 1

替换

getSupportActionBar().setCustomView(R.layout.actionbar_gip);

通过

 getSupportActionBar().setCustomView(mCustomView2);

解决了我的问题..
