我在片段上有一个完美的搜索表单。目前我在表单底部有RecyclerView，但我希望它在新活动中加载搜索结果。请帮忙

}
单击搜索按钮时，我希望它打开新活动并在那里加载结果。
答案 0 :(得分：0)
您可以将此searchText传递给下一个活动（我将其称为ResultsActivity），方法是将其作为额外内容传递给Intent：
private void firebaseUserSearch(String searchText) {
Intent intent = new Intent(getActivity(), ResultsActivity.class);
intent.putExtra("searchText",searchText);
startActivity(intent);
}
String searchText = getIntent().getExtras().getString("searchText");
最后从该Activity中填充RecyclerView：
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);
