我想打電話給從服務器的JSON API中的android：如何在android中的自定義採用者中使用json數組列表？
STEP1
我有一個JSON 2列表（菜單和結果）
{
"page": 1,
"menus": [ { m1:"v1" },{ ... },..., "count_menus": 10],
"results": [ { r1:"v1",r2:"v2" },{ ... },"count_results": 273 ]
, "total_count": 5450, "total_pages": 283
。 }
問題1：首先，json結構是否正確？
---------
我創建了一個MedicAPI.java類：
public class MedicApi {
private static Retrofit retrofit = null;
public static Retrofit getClient() {
if (retrofit == null) {
retrofit = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.baseUrl("http://www.example.com/api/")
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}
和
public interface MedicService {
@GET("service/last.php")
Call<LastMedic> getTopRatedMovies(
@Query("api_key") String apiKey,
@Query("language") String language,
@Query("page") int pageIndex
);
}
而現在，我創建了一些模型：
public class LastMedic {
@SerializedName("page")
@Expose
private Integer page;
@SerializedName("results")
@Expose
private List<LastMedicResult> results = new ArrayList<LastMedicResult>();
@SerializedName("menus")
@Expose
private List<LastMedicMenu> menus = new ArrayList<LastMedicMenu>();
@SerializedName("total_counts")
@Expose
private Integer totalCounts;
@SerializedName("total_pages")
@Expose
private Integer totalPages;
public Integer getPage() {
return page;
}
public void setPage(Integer page) {
this.page = page;
}
public List<LastMedicResult> getResults() {
return results;
}
public void setResults(List<LastMedicResult> results) {
this.results = results;
}
public List<LastMedicMenu> getMenus() {
return menus;
}
public void setMenus(List<LastMedicMenu> menus) {
this.menus = menus;
}
public Integer gettotalCounts() {
return totalCounts;
}
public void settotalCounts(Integer totalCounts) {
this.totalCounts = totalCounts;
}
public Integer getTotalPages() {
return totalPages;
}
public void setTotalPages(Integer totalPages) {
this.totalPages = totalPages;
}
}
而且兩種模式菜單和結果爲LastMedicMenu和LastMedicResults
所以我覺得我的代碼是完整的API。
步驟1，工作在另一個項目
STEP2
這是我的樣本數據Dataserver.java
public class DataServer {
private DataServer() {
}
public static List<MultipleItem> getMultipleItemData() {
List<MultipleItem> list = new ArrayList<>();
for (int i = 0; i <= 5; i++) {
thisCounter++;
list.add(new MultipleItem(MultipleItem.IMG_TEXT, MultipleItem.IMG_TEXT_SPAN_SIZE_MIN,"menu"));
}
for (int i = 0; i <= 10; i++) {
list.add(new MultipleItem(MultipleItem.SERVICE_LIST, MultipleItem.SERVICE_SPAN_SIZE));
}
}
}
和
public class MultipleItem implements MultiItemEntity {
public static final int TEXT = 1;
public static final int TEXT_SPAN_SIZE = 4;
public static final int IMG = 2;
public static final int IMG_SPAN_SIZE = 1;
public static final int IMG_TEXT = 3;
public static final int IMG_TEXT_SPAN_SIZE = 4;
public static final int IMG_TEXT_SPAN_SIZE_MIN = 2;
public static final int SERVICE_LIST = 4;
public static final int SERVICE_SPAN_SIZE = 4;
private int itemType;
private int spanSize;
public MultipleItem(int itemType, int spanSize, String content) {
this.itemType = itemType;
this.spanSize = spanSize;
this.content = content;
}
public MultipleItem(int itemType, int spanSize) {
this.itemType = itemType;
this.spanSize = spanSize;
}
public int getSpanSize() {
return spanSize;
}
public void setSpanSize(int spanSize) {
this.spanSize = spanSize;
}
private String content;
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
@Override
public int getItemType() {
return itemType;
}
}
步驟2，適用於樣本數據。
比如我可以在adobter使用此代碼綁定XML：
protected void convert(BaseViewHolder helper, MultipleItem item) {
switch (helper.getItemViewType()) {
case MultipleItem.TEXT:
helper.setText(R.id.tv, item.getContent());
STEP3
現在，我想合併第一步和第二步。
我的意思是我想用json數據代替樣本數據。
例如，對於這樣的：
for (int i = 0; i <= 5; i++) {
thisCounter++;
list.add(new MultipleItem(MultipleItem.IMG_TEXT, MultipleItem.IMG_TEXT_SPAN_SIZE_MIN,"menu"));
}
我想使用JSON 菜單名單。
併爲此
for (int i = 0; i <= 10; i++) {
list.add(new MultipleItem(MultipleItem.SERVICE_LIST, MultipleItem.SERVICE_SPAN_SIZE));
}
我想用導致JSON列表。
步驟4 這段代碼是真實的負載列表形式的服務器？
callLastMedicApi().enqueue(new Callback<LastMedic>() {
@Override
public void onResponse(Call<LastMedic> call, Response<LastMedic> response) {
List<LastMedicResult> results = fetchResults(response);
List<LastMedicMenu> menus = fetchResults2(response);
}
@Override
public void onFailure(Call<LastMedic> call, Throwable t) {
t.printStackTrace();
//
}
});
private Call<LastMedic> callLastMedicApi() {
return medicService.getTopRatedMovies(
getString(R.string.my_api_key),
"en_US",
currentPage
);
}
如果是的話，怎樣才能使用這段代碼和DataServer類以及MultipleItem類？
我希望能做到這一點（例如）：
protected void convert(BaseViewHolder helper, MultipleItem item) {
switch (helper.getItemViewType()) {
case MultipleItem.TEXT:
helper.setText(R.id.tv, item.getMenu(M1));
