Java Android将片段参数而不是列表传递到ListView

我可以从Web服务器获取数据，并使用以下类将其正确传递到ListView：

ReceiveFields

类结构：

public class ReceiveFields {
    public long lastId;
    public String smsNumber;
    public String mobileNumber;
    public String senderName;
    public String smsBody;
    public String receiveDate;
    private Context ctx;
}

ReceivedSMS

类从Web服务获取数据：

public class ReceivedSMS extends ListFragment implements AbsListView.OnScrollListener {
    private List<ReceiveFields> rows;
    private int prevVisibleItem;
    private TSMS tsms;
    private String username;
    private String password;
    public  Long getLastReceivedSMSID;
    private boolean isFirstTime;
    private Context context;

    public ResivedSMS(Context context, String username, String password) {
        this.username = username;
        this.password = password;
        this.context = context;
    }

    public ResivedSMS(String username, String password, long start, long count,Context context) {
        this.username = username;
        this.password = password;
        this.context = context;
        tsms = new TSMS(context ,new User(username, password));
        getResivedSMS(start , count);
    }

    public ResivedSMS(List<ReceiveFields> receivedSMSList,Context context){
        rows = receivedSMSList;
        this.context = context;
    }

    public List<ReceiveFields> getResivedSMS(long start, long count) {
        tsms = new TSMS(context,new User(this.username, this.password));
        try {
            rows = tsms.getReceivedSMS(start, count);
        }
        catch (TException e) {
            e.printStackTrace();
            Log.e("ERROR IN Fetch SMS From WebService List<ReceiveFields> getResivedSMS(long start, long count) " , String.valueOf(e));
        }
        return rows;
    }

并传递到ListView：

getSupportFragmentManager().beginTransaction().replace(R.id.drawer, receivedSMSList).commit();

所有这些都是正确的，我没有问题。但我想从数据库中获取数据并将其传递，而不是接收数据，如下所示：

List<ReceiveFields> r1 = db.getAllReceivedSMSFromDatabase();

receivedSMSList = new ResivedSMS(r1,context);

getSupportFragmentManager().beginTransaction().replace(R.id.drawer, receivedSMSList).commit();

注意：我的数据库不是空的，有20行

getAllReceivedSMSFromDatabase

返回值与

GetResizedSMS

类似，但我得到以下错误：

getAllReceivedSMSFromDatabase

带有'LogCat:

问题是您正在将一个列表作为参数传递给，而它需要一个片段作为参数

公共抽象片段事务替换（int-containerwid，片段片段）

您已将列表作为参数传递，而不是传递片段

---

尝试传递ReceivedSMS（它

扩展了ListFragment

）而不是ListSMS，后者是一个列表（

列表ListSMS

）

设置列表对象，当它需要片段时，在这里初始化并设置片段类ReceivedSMS。@jitainsharma我做不到。如何？Like ReceivedSMS ReceivedSMS=新的ReceivedSMS（上下文、用户名、密码）；我不相信我，先生。你能用正确的方式粘贴帖子吗TuxWorld 21分钟ago@TuxWorld重复这么多次并不是获得帮助的最佳途径。。。此外，您的时间戳已经在您的消息中，但您也复制了它。

public List<ReceiveFields> getAllReceivedSMSFromDatabase() {
    SQLiteDatabase db = this.getReadableDatabase();
    String selectQuery = "SELECT * FROM " + this.RECEIVE_FIELDS_TABLE ;
    Cursor cursor = db.rawQuery(selectQuery, null);
    List<ReceiveFields> ListSMS = new ArrayList<ReceiveFields>();
    cursor.moveToFirst();
    while (cursor.moveToNext()) {
        ListSMS.add(new ReceiveFields(
                Long.valueOf(cursor.getString(cursor.getColumnIndex("lastId"))),
                cursor.getString(cursor.getColumnIndex("smsNumber")),
                cursor.getString(cursor.getColumnIndex("mobileNumber")),
                cursor.getString(cursor.getColumnIndex("senderName")),
                cursor.getString(cursor.getColumnIndex("smsBody")),
                cursor.getString(cursor.getColumnIndex("receiveDate"))));
    }

    cursor.close();
    db.close();
    return ListSMS;
}
