アンドロイドのテーブルレイアウトでJsonデータを埋める方法

Question

私は自分のjsonデータをテーブルレイアウトに表示しようとしています。そのためにエラーなしで正常に動作するphpwebserviceを1つ用意しています。 tは

TableActivity ..私のコードがある、それはtablelayoutに移入されていないと私のアプリは、残念ながらstopped.hereを持っている理由を理解するここで

Answer 1

あなたString結果からJSONArrayを解析しているが、それはあなたがこのように渡すことにしていJSONOjectです。 ..

JSONObject jObj = new JSONObject(result); 
JSONArray jArray =jObj.getJSONArray("Users"); 
for (int i = 0; i < jArray.length(); i++) { 
    JSONObject json_data = jArray.getJSONObject(i); 
    Users user = new Users(); 
    user.setId(json_data.getInt("id")); 
    user.setName(json_data.getString("name")); 
    user.setUsername(json_data.getString("username")); 
    user.setEmail(json_data.getString("email")); 
    users.add(user); 
} 

Answer 2

テーブルレイアウトに行を追加した方法あなたは、単一の行を複数回追加しているあなたのコードのように複数の行を追加し、あなたのtableLayoutオブジェクトに

てみてください複数TableRowインスタンスを追加することができます。これはために動作します

void addHeader(){ 
    /** Create a TableRow dynamically **/ 
    tr = new TableRow(this); 

    /** Creating a TextView to add to the row **/ 
    label = new TextView(this); 
    label.setText("Name"); 
    label.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, 
      LayoutParams.WRAP_CONTENT)); 
    label.setPadding(5, 5, 5, 5); 
    label.setBackgroundColor(Color.RED); 
    LinearLayout Ll = new LinearLayout(this); 
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, 
      LayoutParams.WRAP_CONTENT); 
    params.setMargins(5, 5, 5, 5); 
    //Ll.setPadding(10, 5, 5, 5); 
    Ll.addView(label,params); 
    tr.addView(Ll); // Adding textView to tablerow. 


    tr1=new TableRow(this); 
    /** Creating Qty Button **/ 
    TextView uname = new TextView(this); 
    uname.setText("Username"); 
    uname.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, 
      LayoutParams.WRAP_CONTENT)); 
    uname.setPadding(5, 5, 5, 5); 
    uname.setBackgroundColor(Color.RED); 
    L2 = new LinearLayout(this); 
    params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, 
      LayoutParams.WRAP_CONTENT); 
    params.setMargins(0, 5, 5, 5); 
    //Ll.setPadding(10, 5, 5, 5); 
    L2.addView(uname,params); 
    tr1.addView(L2); // Adding textview to tablerow. 

    // Add the TableRow to the TableLayout 
    tl.addView(tr); 
    tl.addView(tr1); 


    tr2=new TableRow(this); 

    /** Creating Qty Button **/ 
    TextView email = new TextView(this); 
    email.setText("email"); 
    email.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, 
      LayoutParams.WRAP_CONTENT)); 
    email.setPadding(5, 5, 5, 5); 
    email.setBackgroundColor(Color.RED); 
    L3 = new LinearLayout(this); 
    params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, 
      LayoutParams.WRAP_CONTENT); 
    params.setMargins(0, 5, 5, 5); 
    //Ll.setPadding(10, 5, 5, 5); 
    L3.addView(email,params); 
    tr2.addView(L3); // Adding textview to tablerow. 

    // Add the TableRow to the TableLayout 
    tl.addView(tr2); 
    } 

希望：コードの下に試してみてください
