【发布时间】：2015-11-24 20:07:29
【问题描述】：

每当用户尝试访问列表中的项目时，我的应用程序都会出现问题。此问题仅发生在 5.1 版（Xperia Z2 (D6503)、Z3 Compact Xperia (D5803)）的设备上

该应用程序已经过测试并且在版本 (4.1) (4.4) (2.3.3)、(2.3.7)、(4.0.3)、(4.0.4) 上运行良好

错误报告说：

我无法完全理解源代码的哪一部分有问题。所以我不知道代码的哪一部分必须贴在这里。有时，用户第一次按下元素列表时可以正常工作，但随后出现错误并且不允许再次访问。

以下代码展示了用户如何访问列表项：

 list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View viewClicked,
                                int position, long id) {

                itemList currentlog = (itemList )parent.getItemAtPosition(position);
                sendToFragmentInterface(currentlog.getUserId());
                MyLogs.clear();
        }
    });

此时，会打开一个包含用户个人资料详细信息的片段。但是，您可以从主菜单访问相同的片段并且运行良好。似乎……只有当您尝试从列表中访问时，应用程序才会崩溃。

这是界面：

public interface openUserProfile {
    public void getUserProfile(String user_id);
}

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);

    if (activity instanceof openUserProfile ) {
        listener = (openUserProfile ) activity;
    } else {
        throw new ClassCastException(activity.toString()
                + " must implemenet MyListFragment.interfazCambiaFragment");
    }
}

public void sendToFragmentInterface(String user_id) {

    listener.getUserProfile(user_id);
}

这是 MainActivity 中的代码“getUserProfile”，它持有调用并打开片段：

Bundle args = new Bundle();
    Fragment fragment = new UserProfile();

    args.putString("user_id",user_id);
    fragment.setArguments(args);

    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction()
            .replace(R.id.container, fragment)
            .addToBackStack(null)
            .commit();

    setTitle("Profile");

该应用程序已经过测试并且在版本 (4.1) (4.4) (2.3.3)、(2.3.7)、(4.0.3)、(4.0.4) 上运行良好 ...谁能告诉我什么发生了什么？

【问题讨论】：

错误在HeaderViewListAdapter:164。你能把这段代码贴出来吗？
@DeividiCavarzan 我的片段中没有任何标头适配器。 OnCreate 中只有这一行：'header = ((LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.header_profile, null);'
当然，我的错，没看到包裹

【解决方案1】：

经过一段时间的分析，我意识到 mylogs.clear() 使用它后清理列表的行是导致错误的行。我把它放在那里是因为我认为我可以节省内存。高于 5.0 的 Android 版本不支持此功能。
