如何在android alert對話框中顯示json解析數據？

Question

我必須將java腳本對象表示法解析數據顯示到android的alert對話框中。可能嗎？如果我們看到Play商店應用，並且想要購買或訂閱某部電影，則會顯示提醒對話框以及電影橫幅縮略圖，電影名稱，價格和繼續按鈕。此外，如果你點擊繼續按鈕，另一個對話框打開。所以任何人都可以幫助我，如何創建它？這是Play商店的示例圖片。我想在我的應用程序中創建這種類型的對話框。請建議我天氣有可能與否。

這裏是

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.cartBookDescription); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      inputDialog() 
     } 
    }); 

void inputDialog() { 


    try { 


     textView.setText("my order"); 
     dbhelper.openDataBase(); 
    } catch (SQLException sqle) { 
     throw sqle; 
    } 

    LayoutInflater layoutInflater = LayoutInflater.from(this); 
    View alertDialog = layoutInflater.inflate(R.layout.alert_dialog, null); 

    AlertDialog.Builder alert = new AlertDialog.Builder(this); 
    alert.setView(alertDialog); 



    alert.setTitle("Order Now"); 

    alert.setCancelable(false); 
    alert.setView(edtQuantity); 

    alert.setPositiveButton("Subscribe Now", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int whichButton) { 

      int quantity = 0; 


     } else { 
       dialog.cancel(); 
      } 
     } 
    }); 

    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int whichButton) { 


      dialog.cancel(); 
     } 
    }); 

    alert.show(); 
} 
public void parseJSONData() { 

    try { 
     // request data from menu detail API 
     HttpClient client = new DefaultHttpClient(); 
     HttpConnectionParams.setConnectionTimeout((HttpParams) client.getParams(), 15000); 
     HttpConnectionParams.setSoTimeout((HttpParams) client.getParams(), 15000); 
     HttpUriRequest request = new HttpGet(MenuDetailAPI); 
     HttpResponse response = client.execute(request); 
     InputStream atomInputStream = response.getEntity().getContent(); 


     BufferedReader in = new BufferedReader(new InputStreamReader(atomInputStream)); 

     String line; 
     String str = ""; 
     while ((line = in.readLine()) != null) { 
      str += line; 
     } 


     JSONObject json = new JSONObject(str); 
     JSONArray data = json.getJSONArray("Book"); // this is the "items: [ ] part 

     for (int i = 0; i < data.length(); i++) { 
      JSONObject object = data.getJSONObject(i); 


      Detail_id = object.getString("id"); 
      Detail_audio = object.getString("audiofile"); 
      Detail_bookauthor = object.getString("bookauthor"); 
      Detail_image = object.getString("photo"); 
      Detail_name = object.getString("bookname"); 
      Detail_category = object.getString("bookcategory"); 
      Detail_premium = object.getString("premiumtype"); 
      Detail_price = Double.valueOf(formatData.format(object.getDouble("price"))); 
      Detail_validity = Integer.valueOf((object.getInt("validity")));    
      Detail_description = object.getString("description"); 

     } 


    } catch (MalformedURLException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (JSONException | IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
} 

parseJson方法的AsyncTask下編寫的代碼。 Json數據解析正常，但當我試圖在警報對話框中顯示數據時，警報對話框會崩潰。

Answer 1

是的，你可以。您只需要解析數據並通過創建活動和佈局類來創建自定義對話框。例如可以看出here

Answer 2

你必須創建XML文件，自定義視圖，你想顯示什麼按您的需求量的增加將在警告對話框參考此鏈接How to create a Custom Dialog box in android? 或 https://bhavyanshu.me/tutorials/create-custom-alert-dialog-in-android/08/20/2015
