如何顯示我的SQL數據庫中的數據並垂直顯示在表中

目前我正在使用一個項目來在垂直顯示Android的表中顯示數據庫值。我在水平方向得到了答案，現在我想要垂直方向。如何顯示我的SQL數據庫中的數據並垂直顯示在表中

。

主要Activity.java

public class MainActivity extends Activity { 

String data = "";

       public void run() { 
        ArrayList<Users> users = parseJSON(data); 
        addData(users); 
       } 
      }); 

     } 
    }).start();

     JSONArray jArray = jsono.getJSONArray("agriculture1"); 
     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.setCrop(json_data.getString("crop")); 
      user.setCategory(json_data.getString("category"));

}

activity_main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/activity_main" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" > 

<ScrollView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:fillViewport="true" 
    android:scrollbars="none" 
    android:layout_below="@+id/textView1"> 
    <TableLayout 

     android:layout_width="wrap_content" 
     android:layout_height="0dp" 
     android:stretchColumns="*" 
     android:id="@+id/maintable" > 
    </TableLayout> 
</ScrollView>

你是什麼意思水平？ –

對不起，我需要垂直像第二張圖片。 – Jincy

兩者有什麼區別？看起來相似。你爲什麼要水平？只是獲取數據，並使Listview項目行與Linearlayout方向水平 –

-1

你必須使用1噸能夠？您可以拆分佈局，並使用兩個表格「標題」和一個值作爲表格。

你可以這樣拆分佈局：

<LinearLayout android:orientation="horizontal" android:layout_height="fill_parent" android:layout_width="fill_parent"> 
    <LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="0dp"/> 
    <LinearLayout android:layout_weight="1" android:layout_height="fill_parent" android:layout_width="0dp"/> 
</LinearLayout>

然後添加內佈局內你的表。
