Android 数据库SQLite Cursor数据遍历读取

1、通过query获取数据：

SQLiteDatabase dataBase=sqliteDB.openDB();

String table="tab_running";

String[] columns={"startaddress","startgpstime","startsystime","endaddress","endgpstime","endsystime"};//你要的数据  

String selection="finished=?";  

String[] selectionArgs={"1"};//具体的条件,注意要对应条件字段  

Cursor cursor=dataBase.query(table, columns, selection, selectionArgs, null, null, null);

2、根据列索引遍历读取列数据：

while(cursor.moveToNext())

{

//根据列的索引直接读取  比如第0列的值

   String strValue= cursor.getString(0);  

}

3、根据列名获取列索引遍历读取列数据：

while(cursor.moveToNext())

{

//根据列名获取列索引   

int nameColumnIndex = cursor.getColumnIndex(“username");

String strValue=cursor.getString(nameColumnIndex); 

}
