Question

目前正在发生什么

我在适配器中有2个实体（线性布局），点击它使片段事务成为新片段
这两个元素都会导致新片段
如果我点击一个班轮布局，它的工作正常。但是当我在做的时候测试，我注意到，如果我点击它们两个错误（因为a row有两个点击导致相同的片段）两个提交不能正如错误所暗示的那样工作
在某种程度上我可以解决这个问题，保持我的架构完整

Answer 1

不要全局创建片段事务。每次都必须创建新的片段事务。

Answer 2

分享我的解决方案::

实际上问题已经创建，因为我在适配器中有两个项目，解决这个问题是设置一个会话变量。它可能不是fesable，但它是解决问题的好方法，因为它在许多地方使用

public class AdptHome extends BaseAdapter {

    ArrayList<HashMap<String, String>> listData;
    Context context;
    FragmentManager fm;

    public AdptHome(ArrayList<HashMap<String, String>> _listData,
            Context _context, FragmentManager fragmentManager) {
        // TODO Auto-generated constructor stub
        listData = _listData;
        context = _context;
        fm = fragmentManager;
    }

    @Override
    public int getCount() {
        return listData.size();
    }

    @Override
    public Object getItem(int position) {
        return listData.get(position);
    }

    @Override
    public long getItemId(int position) {
