查看搜索结果新活动

Question

我在片段上有一个完美工作的片段上的搜索表格。目前，我在表单的底部有一个RecyclerView，但我希望它将搜索结果加载到新活动上。请帮助

        Toast.makeText(getActivity(), "Started Search", Toast.LENGTH_LONG).show();
        Query firebaseSearchQuery = mUserDatabase.orderByChild("title").startAt(searchText).endAt(searchText + "uf8ff");

            Glide.with(ctx).load(userImage).into(user_image);

        }


    }

单击搜索按钮时，我希望它打开新活动并加载结果。

您可以将此searchText传递给下一个活动(我称之为结果(，通过将其作为额外的意图传递：

private void firebaseUserSearch(String searchText) {
    Intent intent = new Intent(getActivity(), ResultsActivity.class);
    intent.putExtra("searchText",searchText);
    startActivity(intent);
}

然后使用intent.getExtras((在其他活动上接收它：

String searchText = getIntent().getExtras().getString("searchText");

最终从该活动中填充了回收库：

Query firebaseSearchQuery = mUserDatabase.orderByChild("title").startAt(searchText).endAt(searchText + "uf8ff");
FirebaseRecyclerAdapter<Cars, UsersViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Cars, UsersViewHolder>(
        Cars.class,
        R.layout.list_layout,
        UsersViewHolder.class,
        firebaseSearchQuery
) {
    @Override
    protected void populateViewHolder(UsersViewHolder viewHolder, Cars model, int position) {

        viewHolder.setDetails(getActivity().getApplicationContext(), model.getTitle(), model.getDesc(), model.getImage(), model.getMileage(), model.getTrans(), model.getFuel(), model.getPrice(), model.getLocation());
    }
};
mResultList.setAdapter(firebaseRecyclerAdapter);
