我尝试在数据库中创建2个表，但是我得到了下一个sintax错误：

第一个错误似乎出现在下一行代码中：

String CREATE_ACTIVITIES_DETAILS_TABLE = "CREATE TABLE " +
            TABLE_ACTIVITIES_DETAILS + "(" +
            ACTIVITY_ID + " INTEGER FOREIGN KEY REFERENCES " + 
            TABLE_ACTIVITIES + "(" + KEY_ID + "), " +
            KEY_HEARTRATE + " INTEGER, "+
            KEY_HEARTBEATNO + " INTEGER, "+
            KEY_DISTANCE + " INTEGER, " +
            KEY_SPEED + " INTEGER, " +
            KEY_STRIDES + " INTEGER," +
            KEY_CURRENTDATETIME + " TEXT" +
            ")";
    db.execSQL(CREATE_ACTIVITIES_DETAILS_TABLE);

这是我的DatabaseHandler类：

public class DatabaseHandler extends SQLiteOpenHelper {

// All Static variables
// Database Version
private static final int DATABASE_VERSION = 2;

// Database Name
private static final String DATABASE_NAME = "YastDB.com.yast.db";

// Activities table name
private static final String TABLE_ACTIVITIES = "Activities";
private static final String TABLE_ACTIVITIES_DETAILS = "ActivitiesDetails";

// Activities Table Col names
private static final String KEY_ID = "id";
private static final String KEY_ACTIVITYTYPE = "ActivityType";
private static final String KEY_STARTDATETIME = "StartDateTime";
private static final String KEY_ENDDATETIME = "EndDateTime";


//Activities details table col names
private static final String ACTIVITY_ID = "id";
private static final String KEY_HEARTRATE = "heartRate";
private static final String KEY_HEARTBEATNO = "heartBeatNo";
private static final String KEY_DISTANCE = "Distance";
private static final String KEY_SPEED = "Speed";
private static final String KEY_STRIDES = "Strides";
public static final String  KEY_CURRENTDATETIME = "CurrentDateTime";

private String[] PROJECTION = new String[]{ KEY_ID,
        KEY_ACTIVITYTYPE, KEY_STARTDATETIME,KEY_ENDDATETIME };

private String[] PROJECTIONDETAILS = new String[]{ ACTIVITY_ID,
        KEY_HEARTRATE, KEY_HEARTBEATNO, KEY_DISTANCE,
        KEY_SPEED,KEY_STRIDES,KEY_CURRENTDATETIME};

public DatabaseHandler(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

// Creating Tables
@Override
public void onCreate(SQLiteDatabase db) {
    String CREATE_ACTIVITIES_TABLE = "CREATE TABLE " + TABLE_ACTIVITIES + "("
            + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
            KEY_ACTIVITYTYPE + " INTEGER,"+
            KEY_STARTDATETIME + " TEXT," +
            KEY_ENDDATETIME + " TEXT" +
            ")";
    db.execSQL(CREATE_ACTIVITIES_TABLE);

    String CREATE_ACTIVITIES_DETAILS_TABLE = "CREATE TABLE " + TABLE_ACTIVITIES_DETAILS + "(" +
            ACTIVITY_ID + " INTEGER FOREIGHN KEY REFERENCES " + TABLE_ACTIVITIES + "(" + KEY_ID + "), " +
            KEY_HEARTRATE + " INTEGER, "+
            KEY_HEARTBEATNO + " INTEGER, "+
            KEY_DISTANCE + " INTEGER, " +
            KEY_SPEED + " INTEGER, " +
            KEY_STRIDES + " INTEGER," +
            KEY_CURRENTDATETIME + " TEXT" +
            ")";
    db.execSQL(CREATE_ACTIVITIES_DETAILS_TABLE);
}

// Upgrading database
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    // Drop older table if existed
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_ACTIVITIES);
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_ACTIVITIES_DETAILS);

    // Create tables again
    onCreate(db);
 }

}

ActivityEntity的属性和构造函数如下所示。它为所有属性设置了/ get方法

public class ActivityEntity {

//private variables

private int id;
private int activityType;
private String startDateTime;
private String endDateTime;

// Empty constructor
public ActivityEntity(){

}
// constructor
public ActivityEntity(int id, int activityType, String startDateTime, String endDateTime){
    this.id = id;
    this.activityType = activityType;
    this.startDateTime = startDateTime;
    this.endDateTime = endDateTime;
}

public ActivityEntity(int activityType,  String startDateTime, String endDateTime){
    this.activityType = activityType;
    this.startDateTime = startDateTime;
    this.endDateTime = endDateTime;
}

ActivityDetails的属性和构造函数如下所示。它为所有属性设置了/ get方法

 public class ActivityDetalis {

    //private variables

   private  int activityId;
   private int heartRate;
   private int heartBeatNo;
   private int distance;
   private int speed;
   private int strides;
   private String currentDateTime;
    // Empty constructor
    public ActivityDetalis() {
    }


    public ActivityDetalis(int activityId, int heartRate, int heartBeatNo, int distance, int speed, int strides, String currentDateTime) {
        this.activityId = activityId;
        this.heartRate = heartRate;
        this.heartBeatNo = heartBeatNo;
        this.distance = distance;
        this.speed = speed;
        this.strides = strides;
        this.currentDateTime = currentDateTime;
    }

    public ActivityDetalis(int heartRate, int heartBeatNo, int distance, int speed, int strides, String currentDateTime) {
        this.heartRate = heartRate;
        this.heartBeatNo = heartBeatNo;
        this.distance = distance;
        this.speed = speed;
        this.strides = strides;
        this.currentDateTime = currentDateTime;
    }

答案 0 :(得分：2)

表名中有空格。删除空格，或将表名放在双引号中：

private static final String TABLE_ACTIVITIES_DETAILS = "ActivitiesDetails";

或

private static final String TABLE_ACTIVITIES_DETAILS = "\"Activities Details\"";
