無法將列表發送到其他活動

在按鈕上單擊我必須將已存儲到列表中的數據發送到活動，在該活動中，我有一個列表，列表將顯示已發送的數據從以前的活動。我到目前爲止所做的是： -無法將列表發送到其他活動

在ActivityOne中，我已經解析了數據並設置了數據在列表視圖中。在這裏有一個場景，有一個JSONArray。我將它存儲在一個List中並獲取了該特定對象的所有數據。但在按鈕上單擊我不能將列表發送到另一個活動。這裏是我的代碼： -

pDialog = new ProgressDialog(getActivity()); 
     pDialog.setMessage("Loading...Please Wait..."); 
     pDialog.setCancelable(false); 
     pDialog.show(); 

     Volley.newRequestQueue(getActivity()).add(new JsonObjectRequest(Request.Method.GET, url, new Response.Listener<JSONObject>() { 
      @Override 
      public void onResponse(JSONObject response) { 
       hidePDialog(); 
       try { 
        JSONObject result = response.getJSONObject("result"); 
        JSONArray jsonArray = result.getJSONArray("course"); 

        System.out.println("Course: == >" + result.getJSONArray("course")); 
        for (int i = 0; i < jsonArray.length(); i++) { 
         JSONObject trainingObj = jsonArray.getJSONObject(i); 
         movie = new Movie(); 
         movie.setCourse_id(trainingObj.getString("course_id")); 
         movie.setParent_course_id(trainingObj.getString("parent_course_id")); 
         movie.setCourse_name(trainingObj.getString("course_name")); 
         movie.setCourse_price(trainingObj.getString("course_price")); 
         movie.setCourse_price_dollar(trainingObj.getString("course_price_doller")); 
         movie.setCourse_price_discount_dollar(trainingObj.getString("course_price_discunt_doller")); 
         movie.setCourse_discount_date(trainingObj.getString("course_discunt_date")); 
         movie.setCourse_description(trainingObj.getString("course_description")); 
         movie.setCourse_image(trainingObj.getString("course_image")); 


//      module = trainingObj.getJSONArray("module"); 
//      jsonArray = module.toString(); 
         List<Module> mod1=new ArrayList<Module>(); 

         JSONArray module = trainingObj.getJSONArray("module"); 
         for (int j = 0; j < module.length(); j++) { 
          JSONObject moduleObj = module.getJSONObject(j); 
          modl=new Module(); 
          modl.setModule_id(moduleObj.getString("module_id")); 
          modl.setVideo_price(moduleObj.getString("video_price")); 
          modl.setVideo_price_doller(moduleObj.getString("video_price_doller")); 
          modl.setVideo_price_discunt(moduleObj.getString("video_price_discunt")); 
          modl.setVideo_price_discunt_doller(moduleObj.getString("video_price_discunt_doller")); 
          modl.setVideo_discunt_date(moduleObj.getString("video_discunt_date")); 
          modl.setVideo_type(moduleObj.getString("video_type")); 
          modl.setVideo_link(moduleObj.getString("video_link")); 
          modl.setVideo_image(moduleObj.getString("video_image")); 
          modl.setVideo_description(moduleObj.getString("video_description")); 
          mod1.add(j,modl); 

         } 
         movie.setModulelist(mod1); 



         trainingList.add(movie);

所有數據已經保存在setModuleList。現在在適配器上點擊一個按鈕，我必須將數據發送到另一個活動。但我無法做到這一點。

btn_view_module.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 



       Intent in = new Intent(activity, ViewModule.class); 

       activity.startActivity(in); 

      } 
     });

單例類在下面給出： -

簡短的回答是，您不能直接將您在活動中的列表發送到新活動。您可以使用this方法在您的活動中發送有限數量的數據。

如果這很困難，那麼你也可以使用單例對象並共享這些變量。

我正在使用Singleton對象。讓我更新代碼並與單身人員分享你 –

我無法控制使用它。請建議我該怎麼做才能克服這個問題 –

讓您的類實現Serializable。如果E類型是Serializable，則可以傳遞一個ArrayList。用做它：

intent.putExtra("modulelist", setModuleList);

，並把它在其他活動中使用：

ArrayList<String> moduleList = (ArrayList<String>) getIntent().getSerializableExtra("modulelist");

檢查這個out。

我已經更新了代碼。請看看並建議我該怎麼辦？ –

基本上讓你的模塊類實現可串行化 –

拿出您的Singleton中的公共構造函數，並用一個私有構造函數替換。然後添加一個靜態getInstance（）方法如下。

static Module instance = null;//Declare instance variable 
private Module(){ 

} 

public static Module getInstance(){ 

if(instance != null){ 
    return instance; 
} 
else{ 

instance = new Module(); 
    return instance; 
} 

}

現在，從其他任何地方使用以下方法來暫緩實例。

Module singletonModule = Module.getInstance();

現在您可以對該實例執行任何方法。
