从android中的数据库读取到arraylist

我对android开发非常陌生，不知道如何从

数据库/表

读取arrayList。现在我有：

      Cursor c = myDB.rawQuery("SELECT * FROM " + TableName , null);

       int Column1 = c.getColumnIndex("Field1");
       int Column2 = c.getColumnIndex("Field2");

       // Check if our result was valid.
       c.moveToFirst();
       if (c != null) {
        // Loop through all Results
        do {
         String Name = c.getString(Column1);
         int Age = c.getInt(Column2);
         Data =Data +Name+"/"+Age+"\n";
        }while(c.moveToNext());
       }
       TextView tv = new TextView(this);
       tv.setText(Data);
       setContentView(tv);
      }
      catch(Exception e) {
       Log.e("Error", "Error", e);
      } finally {
       if (myDB != null)
        myDB.close();
      }

//ArrayList of Calllog class objects
ArrayList<CallLog> arrCallLogs = null;
Cursor curCalllog = myDB.rawQuery("SELECT * FROM " + TableName , null);

            if(curCalllog != null && curCalllog.moveToFirst()) {
            arrCallLogs = new ArrayList<CallLog>();
            while (curCalllog.isAfterLast() == false) {
                //Calllog is a class with list of fileds 
                CallLog callLog = new CallLog();
                callLog.setId(curCalllog.getLong(curCalllog.getColumnIndex(KEY_ROWID)));
                callLog.setName(curCalllog.getString(curCalllog.getColumnIndex(KEY_NAME)));
                callLog.setNumber(curCalllog.getString(curCalllog.getColumnIndex(KEY_NUMBER)));
                callLog.setNumberType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NUMBERTYPE)));
                callLog.setCallType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_CALLTYPE)));
                callLog.setDatetime(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DATETIME)));
                callLog.setDuration(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DURATION)));
                callLog.set_new(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NEW)));
                arrCallLogs.add(callLog);
                curCalllog.moveToNext();
            }
        }
        curCalllog.close();
    myDB.close();

如何将其读入arraylist

//调用日志类对象的ArrayList
//ArrayList of Calllog class objects
ArrayList<CallLog> arrCallLogs = null;
Cursor curCalllog = myDB.rawQuery("SELECT * FROM " + TableName , null);

            if(curCalllog != null && curCalllog.moveToFirst()) {
            arrCallLogs = new ArrayList<CallLog>();
            while (curCalllog.isAfterLast() == false) {
                //Calllog is a class with list of fileds 
                CallLog callLog = new CallLog();
                callLog.setId(curCalllog.getLong(curCalllog.getColumnIndex(KEY_ROWID)));
                callLog.setName(curCalllog.getString(curCalllog.getColumnIndex(KEY_NAME)));
                callLog.setNumber(curCalllog.getString(curCalllog.getColumnIndex(KEY_NUMBER)));
                callLog.setNumberType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NUMBERTYPE)));
                callLog.setCallType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_CALLTYPE)));
                callLog.setDatetime(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DATETIME)));
                callLog.setDuration(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DURATION)));
                callLog.set_new(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NEW)));
                arrCallLogs.add(callLog);
                curCalllog.moveToNext();
            }
        }
        curCalllog.close();
    myDB.close();

ArrayList arrCallLogs=null；
游标curCalllog=myDB.rawQuery（“SELECT*FROM”+TableName，null）；
if（curCalllog！=null&&curCalllog.moveToFirst（））{
arrCallLogs=newarraylist（）；
while（curCalllog.isAfterLast（）==false）{
//Calllog是一个包含文件列表的类
CallLog CallLog=new CallLog（）；
setId（curCalllog.getLong（curCalllog.getColumnIndex（KEY_ROWID））；
setName（curCalllog.getString（curCalllog.getColumnIndex（KEY_NAME））；
setNumber（curCalllog.getString（curCalllog.getColumnIndex（KEY_NUMBER））；
callLog.setNumberType（curCalllog.getInt（curCalllog.getColumnIndex（KEY_NUMBERTYPE））；
callLog.setCallType（curCalllog.getInt（curCalllog.getColumnIndex（KEY_CALLTYPE））；
setDatetime（curCalllog.getLong（curCalllog.getColumnIndex（KEY_DATETIME））；
setDuration（curCalllog.getLong（curCalllog.getColumnIndex（KEY_DURATION））；
callLog.set_new（curCalllog.getInt（curCalllog.getColumnIndex（KEY_new））；
arrCallLogs.add（callLog）；
curCalllog.moveToNext（）；
}
}
curCalllog.close（）；
myDB.close（）；

这是如何从游标创建arrayList的示例

//ArrayList of Calllog class objects
ArrayList<CallLog> arrCallLogs = null;
Cursor curCalllog = myDB.rawQuery("SELECT * FROM " + TableName , null);

            if(curCalllog != null && curCalllog.moveToFirst()) {
            arrCallLogs = new ArrayList<CallLog>();
            while (curCalllog.isAfterLast() == false) {
                //Calllog is a class with list of fileds 
                CallLog callLog = new CallLog();
                callLog.setId(curCalllog.getLong(curCalllog.getColumnIndex(KEY_ROWID)));
                callLog.setName(curCalllog.getString(curCalllog.getColumnIndex(KEY_NAME)));
                callLog.setNumber(curCalllog.getString(curCalllog.getColumnIndex(KEY_NUMBER)));
                callLog.setNumberType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NUMBERTYPE)));
                callLog.setCallType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_CALLTYPE)));
                callLog.setDatetime(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DATETIME)));
                callLog.setDuration(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DURATION)));
                callLog.set_new(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NEW)));
                arrCallLogs.add(callLog);
                curCalllog.moveToNext();
            }
        }
        curCalllog.close();
    myDB.close();

这里有一个类名Calllog，它包含文件、setter和getter方法的列表。

这里我使用游标创建了一个Calllog对象的ArrayList，下面是一段代码，它向您展示了如何从数据库查询中获取ArrayList

//ArrayList of Calllog class objects
ArrayList<CallLog> arrCallLogs = null;
Cursor curCalllog = myDB.rawQuery("SELECT * FROM " + TableName , null);

            if(curCalllog != null && curCalllog.moveToFirst()) {
            arrCallLogs = new ArrayList<CallLog>();
            while (curCalllog.isAfterLast() == false) {
                //Calllog is a class with list of fileds 
                CallLog callLog = new CallLog();
                callLog.setId(curCalllog.getLong(curCalllog.getColumnIndex(KEY_ROWID)));
                callLog.setName(curCalllog.getString(curCalllog.getColumnIndex(KEY_NAME)));
                callLog.setNumber(curCalllog.getString(curCalllog.getColumnIndex(KEY_NUMBER)));
                callLog.setNumberType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NUMBERTYPE)));
                callLog.setCallType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_CALLTYPE)));
                callLog.setDatetime(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DATETIME)));
                callLog.setDuration(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DURATION)));
                callLog.set_new(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NEW)));
                arrCallLogs.add(callLog);
                curCalllog.moveToNext();
            }
        }
        curCalllog.close();
    myDB.close();

public ArrayList<String> GetAllValues(String aTable,String[] aColumn)
{
    ArrayList<String> list = new ArrayList<String>();
    Cursor cursor = sqlDB.query(aTable, aColumn, null, null, null, null, null);
    if (cursor.moveToFirst())
    {
        do
        {
            list.add(cursor.getString(0));
        }
        while (cursor.moveToNext());
    }
    if (cursor != null && !cursor.isClosed()) 
    {
        cursor.close();
    }

    return list;
}

public ArrayList GetAllValues（字符串aTable，字符串[]aColumn）
{
ArrayList=新建ArrayList（）；
Cursor Cursor=sqlDB.query（aTable，aColumn，null，null，null，null）；
if（cursor.moveToFirst（））
{
做
{
list.add（cursor.getString（0））；
}
while（cursor.moveToNext（））；
}
if（cursor！=null&！cursor.isClosed（））
{
cursor.close（）；
}
退货清单；
}

如果在“aColumn”中提供null，它将提供所有列。我希望这会有帮助

//ArrayList of Calllog class objects
ArrayList<CallLog> arrCallLogs = null;
Cursor curCalllog = myDB.rawQuery("SELECT * FROM " + TableName , null);

            if(curCalllog != null && curCalllog.moveToFirst()) {
            arrCallLogs = new ArrayList<CallLog>();
            while (curCalllog.isAfterLast() == false) {
                //Calllog is a class with list of fileds 
                CallLog callLog = new CallLog();
                callLog.setId(curCalllog.getLong(curCalllog.getColumnIndex(KEY_ROWID)));
                callLog.setName(curCalllog.getString(curCalllog.getColumnIndex(KEY_NAME)));
                callLog.setNumber(curCalllog.getString(curCalllog.getColumnIndex(KEY_NUMBER)));
                callLog.setNumberType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NUMBERTYPE)));
                callLog.setCallType(curCalllog.getInt(curCalllog.getColumnIndex(KEY_CALLTYPE)));
                callLog.setDatetime(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DATETIME)));
                callLog.setDuration(curCalllog.getLong(curCalllog.getColumnIndex(KEY_DURATION)));
                callLog.set_new(curCalllog.getInt(curCalllog.getColumnIndex(KEY_NEW)));
                arrCallLogs.add(callLog);
                curCalllog.moveToNext();
            }
        }
        curCalllog.close();
    myDB.close();
