我想在垂直recyclerview中创建水平recyclerview，例如Google Play商店，并通过 Volley 和显示获取数据，我看到这个示例http://android-pratap.blogspot.co.uk/2015/12/horizontal-recyclerview-in-vertical.html 但不使用volley在recyclerview中显示数据，如何使用此API在recyclerview水平recyclerview内部垂直recyclerview中使用volley显示数据？ API:http://monaasoft.com/indianfm/api/test.json 请帮助我
数据
public class Data {
private String title;
private List<Section> section;
public Data(){
}
public Data(String title,List<Section> sections){
this.title=title;
this.section=section;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public List<Section> getSection() {
return section;
}
public void setSection(List<Section> section) {
this.section = section;
}
}
部分
public class Section {
private String name;
private String image;
public Section(){
}
public Section(String name,String image){
this.name=name;
this.image=image;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
RecyclerViewDataAdapter
public class RecyclerViewDataAdapter extends
RecyclerView.Adapter<RecyclerViewDataAdapter.ItemRowHolder> {
private List<Data> dataList;
private Context mContext;
public RecyclerViewDataAdapter(Context context, List<Data> dataList) {
this.dataList = dataList;
this.mContext = context;
}
@Override
public ItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v =
LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_item,
null);
ItemRowHolder mh = new ItemRowHolder(v);
return mh;
}
@Override
public void onBindViewHolder(ItemRowHolder itemRowHolder, int i) {
final String sectionName = dataList.get(i).getTitle();
List singleSectionItems = dataList.get(i).getSection();
itemRowHolder.itemTitle.setText(sectionName);
SectionListDataAdapter itemListDataAdapter = new
SectionListDataAdapter(mContext, singleSectionItems);
itemRowHolder.recycler_view_list.setHasFixedSize(true);
itemRowHolder.recycler_view_list.setLayoutManager(new
LinearLayoutManager(mContext, LinearLayoutManager.HORIZONTAL, false));
itemRowHolder.recycler_view_list.setAdapter(itemListDataAdapter);
itemRowHolder.recycler_view_list.setNestedScrollingEnabled(false);
/* itemRowHolder.recycler_view_list.setOnTouchListener(new
View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = event.getAction();
switch (action) {
case MotionEvent.ACTION_DOWN:
// Disallow ScrollView to intercept touch events.
v.getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_UP:
//Allow ScrollView to intercept touch events once again.
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
// Handle RecyclerView touch events.
v.onTouchEvent(event);
return true;
}
});*/
itemRowHolder.btnMore.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(v.getContext(), "click event on more,
"+sectionName , Toast.LENGTH_SHORT).show();
}
});
/* Glide.with(mContext)
.load(feedItem.getImageURL())
.diskCacheStrategy(DiskCacheStrategy.ALL)
.centerCrop()
.error(R.drawable.bg)
.into(feedListRowHolder.thumbView);*/
}
@Override
public int getItemCount() {
return (null != dataList ? dataList.size() : 0);
}
public class ItemRowHolder extends RecyclerView.ViewHolder {
protected TextView itemTitle;
protected RecyclerView recycler_view_list;
protected Button btnMore;
public ItemRowHolder(View view) {
super(view);
this.itemTitle = (TextView) view.findViewById(R.id.itemTitle);
this.recycler_view_list = (RecyclerView) view.findViewById(R.id.recycler_view_list);
this.btnMore= (Button) view.findViewById(R.id.btnMore);
}
}
}
节列表数据适配器
public class SectionListDataAdapter extends
RecyclerView.Adapter<SectionListDataAdapter.SingleItemRowHolder> {
private List<Section> itemsList;
private Context mContext;
public SectionListDataAdapter(Context context, List<Section> itemsList) {
this.itemsList = itemsList;
this.mContext = context;
}
@Override
public SingleItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v =
LayoutInflater.from(viewGroup.getContext())
.inflate(R.layout.list_single_card,
null);
SingleItemRowHolder mh = new SingleItemRowHolder(v);
return mh;
}
@Override
public void onBindViewHolder(SingleItemRowHolder holder, int i) {
Section singleItem = itemsList.get(i);
holder.tvTitle.setText(singleItem.getName());
Glide.with(mContext)
.load(singleItem.getImage())
.diskCacheStrategy(DiskCacheStrategy.ALL)
.centerCrop()
.into(holder.itemImage);
}
@Override
public int getItemCount() {
return (null != itemsList ? itemsList.size() : 0);
}
public class SingleItemRowHolder extends RecyclerView.ViewHolder {
protected TextView tvTitle;
protected ImageView itemImage;
public SingleItemRowHolder(View view) {
super(view);
this.tvTitle = (TextView) view.findViewById(R.id.tvTitle);
this.itemImage = (ImageView) view.findViewById(R.id.itemImage);
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(v.getContext(), tvTitle.getText(),
Toast.LENGTH_SHORT).show();
}
});
}
}
}
主要 Activity
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private RecyclerView my_recycler_view;
private RecyclerView.LayoutManager layoutManager;
private RecyclerView.Adapter adapter;
List<Data> allSampleData;
private String TEST_URL="http://monaasoft.com/indianfm/api/test.json";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
allSampleData=new ArrayList<Data>();
my_recycler_view = (RecyclerView) findViewById(R.id.my_recycler_view);
my_recycler_view.setHasFixedSize(true);
RecyclerViewDataAdapter adapter = new
RecyclerViewDataAdapter(MainActivity.this, allSampleData);
my_recycler_view.setLayoutManager(new
LinearLayoutManager(MainActivity.this, LinearLayoutManager.VERTICAL,
false));
my_recycler_view.setAdapter(adapter);
JsonArrayRequest newreq=new JsonArrayRequest(TEST_URL, new
Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
Log.d("main",""+response);
for (int i=0 ; i<=response.length();i++){
try {
JSONObject sectionObj= (JSONObject) response.get(i);
String title=sectionObj.getString("title");
List<Section> sections=new ArrayList<Section>();
JSONArray sectionArray=sectionObj.getJSONArray("section");
for(int j=0;j<sectionArray.length();j++){
JSONObject obj=(JSONObject) sectionArray.get(j);
Section section = new Section();
section.setName(obj.getString("name"));
section.setImage(obj.getString("image"));
sections.add(section);
Data data= new Data();
data.setTitle(title);
data.setSection(sections);
allSampleData.add(data);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
MySingleton.getInstance(this).addToRequestQueue(newreq);
}
}
我的单例
public class MySingleton {
private static MySingleton mInstance;
private RequestQueue mRequestQueue;
private ImageLoader mImageLoader;
private static Context mCtx;
private MySingleton(Context context) {
mCtx = context;
mRequestQueue = getRequestQueue();
mImageLoader = new ImageLoader(mRequestQueue,
new ImageLoader.ImageCache() {
private final LruCache<String, Bitmap>
cache = new LruCache<String, Bitmap>(20);
@Override
public Bitmap getBitmap(String url) {
return cache.get(url);
}
@Override
public void putBitmap(String url, Bitmap bitmap) {
cache.put(url, bitmap);
}
});
}
public static synchronized MySingleton getInstance(Context context) {
if (mInstance == null) {
mInstance = new MySingleton(context);
}
return mInstance;
}
public RequestQueue getRequestQueue() {
if (mRequestQueue == null) {
// getApplicationContext() is key, it keeps you from leaking the
// Activity or BroadcastReceiver if someone passes one in.
mRequestQueue =
Volley.newRequestQueue(mCtx.getApplicationContext());
}
return mRequestQueue;
}
public <T> void addToRequestQueue(Request<T> req) {
getRequestQueue().add(req);
}
public ImageLoader getImageLoader() {
return mImageLoader;
}
}
