Android将按钮ID从解析的JSON数据输入到列表视图中

Question

如何将解析的JSON数据中的按钮ID从ID列表中输入到列表视图中？

目前我有这个方法：

@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添加到创建的按钮，像这样：

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

后来我想创建一个意图，并发布按钮ID到新的活动是这样的：

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); 
} 

在其他活动我想显示数据相关我发布的ID。

因为即时通讯新的Android开发我不知道如果这是正确的。

编辑：

这是我的适配器：

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类：

/** 
* 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); 
}

我认为有关于如何处理你的问题更好的方法。但是，如果你真的想改变视图的ID（在这种情况下按钮），再有就是对这个

How can I assign an ID to a view programmatically?

Answer 2

我真的不认为分配按钮查看IDS从解析的JSON数据是一些很好的解释好主意。

如何：

1. 获取JSON数据，分析它，并设计数据结构来保存数据，像JsonDataMode在我〔实施例。

2. 解析json数据并将其添加到列表数据结构中，如List。

3. 设计并实现ListView的适配器。用数据列表初始化适配器。

4. 设置子视图的标签，使子视图能够包含数据。

5. 有一个OnclickListener供此列表视图在点击子视图项目时作出反应。
