填充表布局使用JSON字符串

Question

我有一个JSON字符串我的web服务返回如下：

{ “checkrecord”[{ “rollno”： “ABC2”， “百分比”：40，“出席“：12，”错过“：34}]，”Table1“：[]}

上面的String表示我的数据集。我已将字符串转换为JSON对象，现在我想将字符串中的数据放入TableLayout中。

我想在Android应用程序时显示的表是这样的：

rollno  percentage attended missed 
    abc2   40    12  34 

这是我使用的是现在的代码：

//json processing code 

public void jsonprocessing(String c) 
    { 
     try 
     { 

     JSONObject jsonobject = new JSONObject(c); 

     JSONArray array = jsonobject.getJSONArray("checkrecord"); 

     int max = array.length(); 

     for (int j = 0; j < max; j++) 
     { 

    JSONObject obj = array.getJSONObject(j); 
    JSONArray names = obj.names(); 

    for (int k = 0; k < names.length(); k++) 
     { 
      name = names.getString(k); 
      value= obj.getString(name); 
       createtableLayout(); 

     } 


     }  

    } 

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

} 

//create table layout 
public void createtableLayout() 
{ 

    Log.d("values",value); //I am able to see the values abc2,40,12 and 34 over here in logcat 
    TableLayout t= (TableLayout)findViewById(R.id.tablelayout); 
     TableRow r1=new TableRow(this); 
     r1.setLayoutParams(new LayoutParams(
     LayoutParams.FILL_PARENT, 
     LayoutParams.WRAP_CONTENT));  
     TextView t1 = new TextView(this); 
     t1.setText(value); 
     t1.setTextColor(Color.BLACK); 
     t1.setLayoutParams(new LayoutParams(
      LayoutParams.FILL_PARENT, 
      LayoutParams.WRAP_CONTENT)); 
     r1.addView(t1); 
     t.addView(r1, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); 

} 

我TableLayout包含一个按钮和一个作为第一个TableRow的EditText。我点击按钮后，我得到JSON字符串。所以我需要按照我的要求动态插入2个TableRows。

我截至目前XML如下：

<?xml version="1.0" encoding="utf-8"?> 
    <TableLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/tablelayout" 
     android:layout_height="fill_parent" 
     android:layout_width="fill_parent" 
     android:background="#000044"> 
    <TableRow> 

    <EditText 
     android:id="@+id/edittext" 
     android:width="200px" /> 

    <Button 
     android:id="@+id/button" 
     android:text="Check Record"/> 

    </TableRow> 

    </TableLayout> 

所以我的问题是如何增加的2个额外的TableRows，以便它们与字符串值填充？

我的代码无法正常工作。我无法获得所需的输出。

任何人都可以帮助我吗？

感谢

您可以使用多列列表视图你的目的，

解析JSON响应，并得到值到不同的字符串，并使用这个博客你的目的

Multicolumn Listview

你，或许，可以定义你的XML的2个排，使他们最初不可见的。然后在收到您的数据后，将您的数据放在这些行中并使其可见。
