从RecycleView Adapter Onclick启动片段 [英] start Fragment from RecycleView Adapter Onclick

问题描述

我有一个RecycleView Adapter和一个按钮.我希望该按钮启动片段.我可以开始一项活动，但不能开始一段片段.我已经为我的Button

Hi I have A RecycleView Adapter and A button. I want that button to start a Fragment. I can start an activity but not a fragment. I have tried this Onclick method for my Button

@Override
        public void onClick(View v) {
            Bundle bundle = new Bundle();
            bundle.putParcelable("event", events.get(getLayoutPosition()));
            Fragment fragment = new EditEventDetailFragment();
            fragment.setArguments(bundle);
            fragment.getFragmentManager().beginTransaction().replace(R.id.contentMainDrawer,fragment).commit();
        }

但是在调用null对象(contentMainDrawer)时出错是我的主要活动content_layout.

But have error invoke null object (contentMainDrawer) is my Main activity content_layout.

非常感谢您的帮助.片段主机回收视图是从Mainactivity调用的

Any help is much appreciate. The Fragment host recycle view is call from Mainactivity

Hi I have found 2 answer that help whoever needed. The answer is to use the Activity that host the calling fragment. Many thanks @Mohit Suthar

Bundle bundle = new Bundle();
            bundle.putParcelable("event", events.get(getLayoutPosition()));
            Fragment fragment = new EditEventDetailFragment();
            fragment.setArguments(bundle);

            FragmentManager fragmentManager = ((MainActivity) context).getSupportFragmentManager();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.contentMainDrawer, fragment, "tag").commit();
