不兼容的类型：android.app.FragmentManager无法转换为android.support.v4.app.FragmentManager

-1

我一直在Error：（103，92）错误：不兼容的类型：android.app.FragmentManager无法转换到android.support.v4.app.FragmentManager不兼容的类型：android.app.FragmentManager无法转换为android.support.v4.app.FragmentManager

我已阅读关于此主题在stackoverflow上的所有可用的帖子。问题是，我试图从一个类中打开片段和活动都不扩展的片段。

这是一个类，我从数据库中填充了我的listview。

请任何帮助appriciated。

这是我的代码

AllModuleRequestList

      } 
     }); 

    } catch (Exception e) { 

     e.printStackTrace(); 
    } 


    return listViewItem; 
} 




}

请帮助。除了FragmentManager之外，其他所有的东西都在工作。谢谢

顺便说一句，不要使用字符串数组。做一个实际的'Module'类。 https://github.com/codepath/android_guides/wiki/Using-an-ArrayAdapter-with-ListView#using-a-custom-arrayadapter –

@ cricket_007，铸造FragmentActivity为我工作。非常感谢，也感谢其他人。我也将采取此建议 – devloper2009

你不应该打电话getFragmentManager()。 1）这不是支持片段2）你应该只从Activity类调用它，而不是在适配器中。

您可以在该Adapter的构造函数中添加一个android.support.v4.app.FragmentManager，这可能是获取所需内容的最简单方法。

public AllModulesRequestList(Context context, FragmentManager fm, ....) { 
    super(context, R.layout.fragment_allmodules_layout, ModuleID); 
    this.context = context; 
    this.fm = fm; 
    ....

而且从创建适配器，通过在getSupportFragmentManager()

铸造FragmentActivity为我工作 – devloper2009

它会工作，但不建议使您的适配器依赖明确的FragmentActivity –

谢谢，这是一个更好的解决方案。我删除了铸件并使用这种方法。你是一个安全的生活 – devloper2009
