【问题描述】：

我想将我的数据从 sqlite 显示到我使用 xml 使用 tablelayout 创建的表中，我想怎么做？有什么例子吗？我不知道如何将值传递到表中。它和我们做 listview 或 textview 一样吗？

下面是我的xml

这是我的代码..

private SQLiteDatabase database;
private ArrayList<String> result = new ArrayList<String>(); 
private ArrayList<Long> idList = new ArrayList<Long>();
private ArrayAdapter<String> adapter;

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.glucose_view);
    TableLayout myTable = (TableLayout)findViewById(R.id.myTableLayout);

    DBHelper helper = new DBHelper(this);
    database = helper.getWritableDatabase();

    // view data

    try{
        String query = "select * from " + DBHelper.TABLE_GLUCOSE;

        Cursor c = database.rawQuery(query, null);

        c.moveToFirst();
        c.moveToPosition(3);  // may be two, not sure if the cursor starts at 0 or 1
        while (c.isAfterLast() == false) {
            String tblName = c.getString(1);
            Cursor table = database.rawQuery("SELECT * FROM " + DBHelper.TABLE_GLUCOSE,null);
            table.moveToFirst();
            if (table.getString(table.getColumnIndex("Title")) != null) {
                //  Your code to create table
            }
            c.moveToNext();
        }
}

谁能帮帮我..

【问题讨论】：

您是否尝试使用此代码...它提供了什么...
和我们做listview或者textview一样吗？ => 是的，这很简单，因为我们在 TextView 中设置了值。
这是什么意思？在 textview 中设置值？
我可以这样使用吗？ try{ if( cursor != null ){ if (cursor.moveToFirst()) { do { idList.add(cursor.getInt(0)); list.add(cursor.getString(1));} while (cursor.moveToNext()); } } } catch(SQLException e){ } cursor.moveToFirst(); TextView TV_Name = (TextView) findViewById(R.id.TVName);TV_Name.setText(cursor.getString(1));cursor.close();
你的问题是什么，你想达到什么目的，为什么要把光标移到第4条记录

【解决方案1】：

试试这个

  if((cursor.moveToFirst())
      {
      do
       {
      LinearLayout layout=new LinearLayout(context);
      layout.setOrienation(LinearLayout.HORIZONTAL);
       for(int i=0;i<cursor.getColumnCount();i++)
        {
         TextView text=new TextView(context);
         switch(cursor.getType(i))      
         {
          case  Cursor.FIELD_TYPE_INTEGER:
           text.setText(String.valueOf(cursor.getInt(i)))
           break;
       case  Cursor.FIELD_TYPE_STRING:
           text.setText(cursor.getString(i))
           break;
...
..


          }
layout.addView(text);

        }
    tablelayout.addView(layout);
        }
        }whilie(cursor.moveToNext())

在你的活动内容上下文中声明一个全局变量上下文；并在 onCreate 中设置 context=this，现在使用这个上下文变量。上下文意味着范围
真的很抱歉，我只是这方面的初学者，这与我创建的 xml 代码一起使用对吗？但是我们想如何用我们想要显示的数据来声明 tablerows？
按下控制键，然后光标后的空格会显示可用的方法，developer.android.com/reference/android/database/…
它显示，但不在我创建的表中.. 我想如何将 db 中的第 1 列放在 android 表布局中的 column1 中
