【中文标题】在表格布局中显示来自 sqlite 的数据，【英文标题】：Display data from sqlite in Table layout, 【发布时间】：2013-02-22 06:56:03 【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 【参考方案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())
【讨论】：
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 @user2089567 我会在 20 分钟后回来以上是关于在表格布局中显示来自 sqlite 的数据，的主要内容，如果未能解决你的问题，请参考以下文章
