Android將按鈕ID從解析的JSON數據輸入到列表視圖中

Question

如何將解析的JSON數據中的按鈕ID從ID列表中輸入到列表視圖中？

目前我有這個方法：

@Override 
    protected void onPostExecute(Void result) { 
     super.onPostExecute(result); 
     // Dismiss the progress dialog 
     if (pDialog.isShowing()) 
      pDialog.dismiss(); 
     /** 
     * Updating parsed JSON data into ListView 
     * */ 
     ListAdapter adapter = new SimpleAdapter(
       MainActivity.this, contactList, 
       R.layout.list_item, new String[]{"name", "description", 
       "release_at", "details" }, new int[]{R.id.name, 
       R.id.description, R.id.release_at}); 

     lv.setAdapter(adapter); 
    } 

我想要的ID添加到創建的按鈕，像這樣：

<Button 
     android:id="@+id/gameDetails"  // <- here I want to add my id 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content"/> 

後來我想創建一個意圖，併發布按鈕ID到新的活動是這樣的：

public void openDetails(View view) { 
    String getContactId = new GetContacts().getButtonId(); 
    Intent paralaxActivityItent = new Intent(MainActivity.this, ParalaxToolbarActivity.class); 
    paralaxActivityItent.putExtra("id", id); // the button id 
    MainActivity.this.startActivity(paralaxActivityItent); 
} 

在其他活動我想顯示數據相關我發佈的ID。

因爲即時通訊新的Android開發我不知道如果這是正確的。

編輯：

這是我的適配器：

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.ViewHolder> { 

    private List<String> friends; 
    private Activity activity; 
    private ArrayList<HashMap<String, String>> contactList; 

    public RecyclerAdapter(Activity activity, List<String> friends) { 
     this.friends = friends; 
     this.activity = activity; 
    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) { 

     //inflate your layout and pass it to view holder 
     LayoutInflater inflater = activity.getLayoutInflater(); 
     View view = inflater.inflate(android.R.layout.simple_list_item_1, viewGroup, false); 
     ViewHolder viewHolder = new ViewHolder(view); 

     return viewHolder; 
    } 

    @Override 
    public void onBindViewHolder(RecyclerAdapter.ViewHolder viewHolder, int position) { 

     viewHolder.item.setText(friends.get(position)); 
    } 

    @Override 
    public int getItemCount() { 
     return (null != friends ? friends.size() : 0); 
    } 

    /** 
    * View holder to display each RecylerView item 
    */ 
    protected class ViewHolder extends RecyclerView.ViewHolder { 
     private TextView item; 

     public ViewHolder(View view) { 
      super(view); 
      item = (TextView) view.findViewById(android.R.id.text1); 
     } 
    } 

} 

MyGetContact類：

/** 
* Async task class to get json by making HTTP call 
*/ 
private class GetContacts extends AsyncTask<Void, Void, Void> { 

    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     // Showing progress dialog 
     pDialog = new ProgressDialog(MainActivity.this); 
     pDialog.setMessage("Please wait"); 
     pDialog.setCancelable(false); 
     pDialog.show(); 

    } 

    @Override 
    protected Void doInBackground(Void... arg0) { 
     HttpHandler sh = new HttpHandler(); 

     // Making a request to url and getting response 
     String jsonStr = sh.makeServiceCall(url); 

     Log.e(TAG, "Response from url: " + jsonStr); 

     if (jsonStr != null) { 
      try { 
       // Getting JSON Array node 
       JSONArray jsonArray = new JSONArray(jsonStr); 

       // looping through All Contacts 
       for (int i = 0; i < jsonArray.length(); i++) { 
        JSONObject c = jsonArray.getJSONObject(i); 

        String id = c.getString("id"); 
        String name = c.getString("name"); 
        String description = c.getString("description"); 
        String video_url = c.getString("video_url"); 
        String platform = c.getString("platform"); 
        String avaible = c.getString("avaible"); 
        String release_at = c.getString("release_at"); 

        // tmp hash map for single contact 
        HashMap<String, String> data = new HashMap<>(); 

        // adding each child node to HashMap key => value 
        data.put("id", id); 
        data.put("name", name); 
        data.put("description", description); 
        data.put("video_url", video_url); 
        data.put("platform", platform); 
        data.put("release_at", release_at); 

        // adding contact to contact list 
        contactList.add(data); 
       } 
      } catch (final JSONException e) { 
       Log.e(TAG, "Json parsing error: " + e.getMessage()); 
       runOnUiThread(new Runnable() { 
        @Override 
        public void run() { 
         Toast.makeText(getApplicationContext(), 
           "Json parsing error: " + e.getMessage(), 
           Toast.LENGTH_LONG) 
           .show(); 
        } 
       }); 

      } 
     } else { 
      Log.e(TAG, "Couldn't get json from server."); 
      runOnUiThread(new Runnable() { 
       @Override 
       public void run() { 
        Toast.makeText(getApplicationContext(), 
          "Couldn't get json from server. Check LogCat for possible errors!", 
          Toast.LENGTH_LONG) 
          .show(); 
       } 
      }); 

     } 

     return null; 
    } 
@Override 
protected void onPostExecute(Void result) { 
    super.onPostExecute(result); 
    // Dismiss the progress dialog 
    if (pDialog.isShowing()) 
     pDialog.dismiss(); 
    /** 
    * Updating parsed JSON data into ListView 
    * */ 
    ListAdapter adapter = new SimpleAdapter(
      MainActivity.this, contactList, 
      R.layout.list_item, new String[]{"name", "description", 
      "release_at", "details" }, new int[]{R.id.name, 
      R.id.description, R.id.release_at}); 

    lv.setAdapter(adapter); 
}

我認爲有關於如何處理你的問題更好的方法。但是，如果你真的想改變視圖的ID（在這種情況下按鈕），再有就是對這個

How can I assign an ID to a view programmatically?

Answer 2

我真的不認爲分配按鈕查看IDS從解析的JSON數據是一些很好的解釋好主意。

如何：

1. 獲取JSON數據，分析它，並設計數據結構來保存數據，像JsonDataMode在我〔實施例。

2. 解析json數據並將其添加到列表數據結構中，如List。

3. 設計並實現ListView的適配器。用數據列表初始化適配器。

4. 設置子視圖的標籤，使子視圖能夠包含數據。

5. 有一個OnclickListener供此列表視圖在點擊子視圖項目時作出反應。
