【中文标题】以编程方式创建多个recycleviewer Android【英文标题】：creating multiple recycleviewer programmatically Android 【发布时间】：2018-04-29 05:44:39 【问题描述】：我想通过循环遍历我的Json 结果来创建可以多次使用的RecyclerView。
我想要的是创建产品类别（RecyclerViews），每个产品都包含可以水平滚动的产品，就像这些Image 一样。
所以我在Internet 周围搜索了任何东西。
然后我决定这样做：
-
创建多个 recyclerView（例如 recycler_1、recycler_2）
然后循环通过我的 Json，同时将适配器 (
data) 添加到这些回收器中
现在我的问题是，当用户到达底部时，我想添加更多类别（及其产品），我不知道如何以编程方式或任何其他替代方式添加更多 recyclerViews。
这是我的一些代码：
这是我的 Json 结果
"products":[
"category":[
"category_name":"Audio & TV"
,
"inner_products":[
"id":"3442",
"product_thumb":"19279c812c9e56a0ca8fea095f36cb22.jpeg",
"brand_name":"Others",
"product_name":"4ga wiring kit",
"saved_amount":"0",
"product_price":"269",
"supplier_logo":"467909bb980b06aca7588be54fa4cb68.jpeg"
,
"id":"3444",
"product_thumb":"dd07c851cfaf1830f6b44f7c55298a18.jpeg",
"brand_name":"Kenwood",
"product_name":"car radio double din ",
"saved_amount":"400",
"product_price":"2299",
"supplier_logo":"467909bb980b06aca7588be54fa4cb68.jpeg"
]
]
,
"category":[
"category_name":"building tools"
,
"inner_products":[
"id":"124",
"product_thumb":"c482e6b5ea0ee76c4e6524b86442bf27.png",
"brand_name":"Others",
"product_name":"drill bosch blue cordless 18v 4a",
"saved_amount":"0",
"product_price":"3695",
"supplier_logo":"21fa5955772bea6a5a1beae155860e6f.jpeg"
,
"id":"123",
"product_thumb":"124591fc38e03702774c99fa00515ca7.png",
"brand_name":"Others",
"product_name":"grinder bosch blue angle 125mm 850w",
"saved_amount":"0",
"product_price":"799.95",
"supplier_logo":"21fa5955772bea6a5a1beae155860e6f.jpeg"
]
]
]
这就是我如何循环遍历Json
final ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setMessage("Loading ");
progressDialog.show();
StringRequest productsStringrequest = new StringRequest(Request.Method.GET, products_url,
new Response.Listener<String>()
@Override
public void onResponse(String response)
progressDialog.dismiss();
try
JSONObject jsonObject = new JSONObject(response);
JSONArray productsArray = jsonObject.getJSONArray("products");
for (int i = 0; i < productsArray.length(); i++)
int[] procustRecycler = new int[]R.id.procustRecycler_0, R.id.procustRecycler_1, R.id.procustRecycler_2, R.id.procustRecycler_3, R.id.procustRecycler_4, R.id.procustRecycler_5, R.id.procustRecycler_6, R.id.procustRecycler_7, R.id.procustRecycler_8, R.id.procustRecycler_9;
int[] pr_header = new int[]R.id.product_header_0, R.id.product_header_1, R.id.product_header_2, R.id.product_header_3, R.id.product_header_4, R.id.product_header_5, R.id.product_header_6, R.id.product_header_7, R.id.product_header_8, R.id.product_header_9 ;
JSONObject categoryObject = productsArray.getJSONObject(i);
JSONArray categoryArray = categoryObject.getJSONArray("category");
for (int b = 0; b < categoryArray.length(); b++)
JSONObject singleCategoryObject = categoryArray.getJSONObject(0);
RecyclerView allProductsRecycler = (RecyclerView) findViewById(procustRecycler[i]);
allProductsRecycler.setHasFixedSize(true);
allProductsRecycler.setLayoutManager(new LinearLayoutManager(Products.this, LinearLayoutManager.HORIZONTAL, false));
List<ProductsItems> products_list = new ArrayList<>();
if(b == 0)
TextView product_header = (TextView) findViewById(pr_header[i]);
product_header.setText(singleCategoryObject.getString("category_name"));
continue;
JSONObject productsCategoryObject = categoryArray.getJSONObject(b);
JSONArray singleProductsArray = productsCategoryObject.getJSONArray("inner_products");
for (int c=0; c< singleProductsArray.length(); c++)
JSONObject object = singleProductsArray.getJSONObject(c);
ProductsItems items = new ProductsItems(
object.getInt("id"),
object.getString("product_name"),
object.getString("product_thumb"),
object.getString("supplier_logo"),
object.getString("brand_name"),
object.getString("product_price"),
object.getString("saved_amount")
);
products_list.add(items);
RecyclerView.Adapter allProductsAdapter = new ProductsAdapter(products_list, getApplicationContext());
allProductsRecycler.setAdapter(allProductsAdapter);
catch (JSONException e)
System.out.println(e.getMessage());
Toast.makeText(Products.this, "Catche error: "+e.getMessage(), Toast.LENGTH_LONG).show();
,
new Response.ErrorListener()
@Override
public void onErrorResponse(VolleyError error)
progressDialog.dismiss();
if (error instanceof TimeoutError )
Toast.makeText(Products.this, "Network time out", Toast.LENGTH_LONG).show();
else if (error instanceof AuthFailureError)
Toast.makeText(Products.this, "Login fail", Toast.LENGTH_LONG).show();
else if (error instanceof ServerError)
Toast.makeText(Products.this, "Server error", Toast.LENGTH_LONG).show();
else if (error instanceof NetworkError)
Toast.makeText(Products.this, "Network error", Toast.LENGTH_LONG).show();
else if (error instanceof ParseError)
Toast.makeText(Products.this, "Unknown", Toast.LENGTH_LONG).show();
);
SingleTon.getInstance(getApplicationContext()).addToRequestQue(productsStringrequest);
