相当多的java文件和布局。如果需要，将上传。

Answer 1

请提供替换片段的视图的正确ID。

FragmentManager fragmentManager = getSupportFragmentManager（）; fragmentManager.beginTransaction（）。replace（R.id.note_list_container，fragment）.commit（）;

请提供容器R.id.note_list_container的正确ID，您希望在其中替换您的片段。它必须在您的活动布局中。框架布局可以是。所以请提供FrameLayout的正确ID。

Answer 2

我遇到了同样的问题，我的解决方案是使单个窗格id具有相同的名称在这里查看

one pane

two panes

两个文件中每个帧布局的ID必须相同

处理片段
