Android通过getSupportFragmentManager将类数据传入ListVew

Question

从webServer或DataBase获取数据后，我想用getSupportFragmentManager将数据传递给ListView。此方法从具有以下结构的类中获取数据：

public class ReceiveFields {

    public long lastId;
    public String 
    public String 
    public String 
    public String 
    public String 
    private Context 
    public 
  }
}

从数据库中传递和获取数据：

ListSMS = db.getAllReceivedSMSFromDatabase();

getAllReceivedSMSFromDatabase函数：

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;

    }

getAllReceivedSMSFromDatabase函数没有任何问题，可以以List<ReceiveFields>格式返回数据

创建数据并将其传递到ListView

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

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

我现在得到了一个错误：

Error:(288, 63) java: no suitable method found for replace(int,java.util.List<ir.tsms.wsdl.ReceiveFields>)
    method android.support.v4.app.FragmentTransaction.replace(int,android.support.v4.app.Fragment,java.lang.String) is not applicable
      (actual and formal argument lists differ in length)
    method android.support.v4.app.FragmentTransaction.replace(int,android.support.v4.app.Fragment) is not applicable
      (actual argument java.util.List<ir.tsms.wsdl.ReceiveFields> cannot be converted to android.support.v4.app.Fragment by method invocation conversion)

因为我没弄错，你正在尝试替换一个List而不是Fragment，getSupportFragmentManager().beginTransaction().replace期望一个占位符和一个你没有提供的片段对象。

编辑:您不能通过replace以这种方式将数据结构传递给片段！您可以在替换yourFragment对象后获取它，然后将数据作为参数传递给它，或者定义一个接口并实现callBack方法：

YouFragment frag = (YouFragment) SupportfragmentManager.findFragmentByTag("YourFragment");
frag.initList(ReceivedSmsList);
