Question

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

我已经在stackoverflow上阅读了关于此主题的所有可用帖子。问题是我试图从Fragment和Activity都没有扩展的类中打开一个片段。

这是一个我从数据库中填充listview的类。

请，任何帮助都应该得到满足。

这是我的代码

请帮助。除了FragmentManager之外，其他所有工作都在工作。感谢

你不应该致电getFragmentManager()。 1）那不是支持片段2）你应该只从Activity类调用它，而不是在适配器中调用它。

您可以在该适配器的构造函数中添加android.support.v4.app.FragmentManager，这可能是获得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;
    ....

从适配器的创建开始，传入getSupportFragmentManager()
