Question

这里是OnClickListener：

holder.btnTakeTest.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        ((FragmentActivity) mCtx).getSupportFragmentManager().beginTransaction()
            .replace(R.id.container_id, new TestFragment(), "TestFragment")
            .addToBackStack(null)
            .commit();
   }
});

这是堆栈跟踪：

这是按钮findviewby id：

 public static class RecyclerVH extends RecyclerView.ViewHolder {

    Button btnTakeTest;

    public RecyclerVH(@NonNull View itemView) {
        super(itemView);

        btnTakeTest = itemView.findViewById(R.id.btn_take_test);
    }
}

Answer 1

您的布局文件必须缺少Fragment元素，或者其id不是container_id。

func loadInitialState<T>(inital: InitialState) -> T?  {
    switch inital {
    case .listTableView(let test):
        return test as? T
    }
    return nil
}

请检查您的布局文件。
