【问题描述】：
我正在尝试在 android 的回收站视图中显示数据。我但它一直只显示最后的数据，我不知道为什么。我似乎做的一切都是正确的。并且recycler view有一个view pager。
这是我的 我的适配器类
public class MyAdapter extends RecyclerView.Adapter<MyHolder> {
Context c;
List<Getter> getter;
public MyAdapter(List<Getter> getter, Context c) {
super();
this.c = c;
this.getter = getter;
}
//INITIALIZE VIEWHODER
@Override
public MyHolder onCreateViewHolder(ViewGroup parent, int viewType) {
//VIEW OBJ
View v= LayoutInflater.from(parent.getContext()).inflate(R.layout.model,null);
//HOLDER
MyHolder holder=new MyHolder(v);
return holder;
}
//BIND VIEW TO DATA
@Override
public void onBindViewHolder(MyHolder holder, int position) {
String images[] = {getter.get(position).getUrl1(), getter.get(position).getUrl2()};
holder.gamename.setText(getter.get(position).getGame_name());
holder.cost.setText(getter.get(position).getCost());
holder.usname.setText(getter.get(position).getFull_name());
Picasso.with(c)
.load(getter.get(position).getPicture())
.placeholder(R.drawable.placeholder)
.error(R.drawable.error)
.transform(new CircleTransform())
.fit()
.into(holder.usimage);
CustomPagerAdapter mCustomPagerAdapter = new CustomPagerAdapter(c,images);
holder.mViewPager.setAdapter(mCustomPagerAdapter);
holder.indicator.setViewPager(holder.mViewPager);
holder.setItemClickListener(new ItemClickListener() {
@Override
public void onItemClick(View v, int pos) {
Snackbar.make(v,getter.get(pos).getGame_name(),Snackbar.LENGTH_SHORT).show();
}
});
}
@Override
public int getItemCount() {
return getter.size();
}
}
这是我的 mainactivty 类
public class All_timeline extends Fragment {
SqlHandler sqlHandler;
RecyclerView rv;
MyAdapter adapter;
private List<Getter> getter;
public All_timeline() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View x = inflater.inflate(R.layout.all_timeline, container, false);
sqlHandler = new SqlHandler(getActivity());
//recycler
rv = (RecyclerView) x.findViewById(R.id.mRecycler);
getter= new ArrayList<>();
rv.setLayoutManager(new LinearLayoutManager(getActivity()));
rv.setItemAnimator(new DefaultItemAnimator());
rv.addItemDecoration(new SimpleDividerItemDecoration(getResources()));
registerUser("arinzeaco@gmail.com");
adapter=new MyAdapter(getter,getActivity());
rv.setAdapter(adapter);
return x;
}
public void registerUser(final String email) {
OkHttpClient client = new OkHttpClient();
RequestBody body = new FormBody.Builder()
.add("username", email)
.build();
Request request = new Request.Builder().url("http://www.thethinker.com.ng/gamer/allpost.php").post(body).build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
Toast.makeText(getActivity(), "Registration failed",
Toast.LENGTH_SHORT).show();
}
@Override
public void onResponse(Call call, Response response) throws IOException {
final String myResponse = response.body().string();
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
JSONObject jso;
Getter contactListItems = new Getter();
try {
jso = new JSONObject(myResponse);
JSONArray categories = jso.getJSONArray("posts");
for (int i = 0; i < categories.length(); i++) {
String image1 = categories.getJSONObject(i).getString("image_1");
String image2 = categories.getJSONObject(i).getString("image_2");
String username = categories.getJSONObject(i).getString("username");
String video_url = categories.getJSONObject(i).getString("video_url");
String liked = categories.getJSONObject(i).getString("liked");
String cost = categories.getJSONObject(i).getString("cost");
String following = categories.getJSONObject(i).getString("following");
String game_name = categories.getJSONObject(i).getString("game_name");
String full_name = categories.getJSONObject(i).getString("full_name");
String userimage = categories.getJSONObject(i).getString("userimage");
contactListItems.setUsername(username);
contactListItems.setGame_name(game_name);
contactListItems.setCost(cost);
contactListItems.setFollowing(following);
contactListItems.setLiked(liked);
contactListItems.setFull_name(full_name);
contactListItems.setVideo(video_url);
contactListItems.setUrl1(image1);
contactListItems.setUrl2(image2);
contactListItems.setPicture(userimage);
getter.add(contactListItems);
}
} catch (JSONException e) {
e.printStackTrace();
}
}});
}
});
}
}
我还检查了其他 stackoverflow 问题，例如 RecyclerView displaying the last item in the adapter several times. Need all adapter items to show in RecyclerView。但我只是不明白我做错了什么。
