从适配器（类）通过EventBus跳转到Fragment并传值 超简单

在适配器类里做一个点击监听（EventBus使用截EventBus使用）

viewHolder.itemView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { int id = rxxp.getCommodityList().get(i).getCommodityId(); EventBus.getDefault().post(id);//EventBus发送 } });

到你要接收的Fragment里接收替换

/** * 从适配器传过来id 替代当前Fragment * @param id */ @Subscribe(threadMode = ThreadMode.MAIN) public void getMessage(Integer id) { Log.d(TAG, "getMessage: " + id); String ID = id.toString(); DetailsFrgament detailsFrgament = new DetailsFrgament();//要替换的Frameent类 Bundle bundle = new Bundle();//传值用 bundle.putString("ids",ID); detailsFrgament.setArguments(bundle); getFragmentManager()//开启事务管理 .beginTransaction() .addToBackStack(null)//将当前Fragment加入到返回栈 .replace(R.id.home_frameLayout,detailsFrgament).commit();//home_frameLayout是当前布局里的FrameLayout }

我的布局
