sqlite的光標設置錯列

Question

爲什麼這個光標：

Objects object = new Objects(cursor.getString(0),cursor.getString(1), 
       cursor.getString(2),cursor.getString(3)); 

我有這樣的結果：

Objects{id=1, name='http://www.escmobile.com/projects/android/okhttp/saul.jpg', url='null', type='null' 

但選擇的結果是這樣的

TYPE=IMAGES NAME=Image1 URL=http://www.escmobile.com/projects/android/okhttp/saul.jpg 

這種方式我插入數據

void addObjects(Objects object) { 
    SQLiteDatabase db = this.getWritableDatabase(); 
    onCreate(db); 
    ContentValues values = new ContentValues(); 

    //values.put(OBJECT_ID,object.getId()); // OBJECT Name 
    values.put(OBJECT_NAME, object.getName()); // OBJECT Name 
    values.put(OBJECT_URL, object.getUrl()); // OBJECT URL 
    values.put(OBJECT_TYPE, object.getType()); // Contact type 
    System.out.println(values); 

    // Inserting Row 
    long id = db.insert(TABLE_OBJECTS, null, values); 
    System.out.println("id:"+id); 
    db.insert(TABLE_OBJECTS, null, values); 
    db.close(); // Closing database connection 
} 

//從主要活動

DatabaseHandler db = new DatabaseHandler(getApplicationContext()); 
Log.d("Insert: ", "Inserting .."); 
db.addObjects(new Objects("Image1", "http://www.escmobile.com/projects/android/okhttp/saul.jpg", "IMAGES", "Leb Funny")); 
db.addObjects(new Objects("Image1", "http://www.escmobile.com/projects/android/okhttp/saul.jpg","IMAGES","Leb Funny")); 
db.addObjects(new Objects("Image1", "http://www.escmobile.com/projects/android/okhttp/saul.jpg", "IMAGES", "Leb Funny")); 


List<Objects> Objects = db.getAllObjects(); 
Log.d("hehe","tttttt"); 
System.out.println(Objects); 
DBadapter adapter = new DBadapter(getApplicationContext(), R.layout.grid_item_layout, Objects); 

這個Object類

public Objects(String name, String url,String type,String category) { 
     //this.id=id; 
     this.name = name; 
     this.url = url; 
     this.type = type; 
     this.category =category; 
    } 
    public Objects() 
    { 

    } 
    public int getId() 
    { 
     return id; 
    } 

    public String getName() 
    { 
     return name; 
    } 

    public String getUrl() 
    { 
     return url; 
    } 
    public String getType() 
    { 
     return type; 
    } 

    public String getCategory() 
    { 
     return category; 
    } 
    public void setId(int id) 
    { 
     this.id=id; 
    } 

    public void setName(String name) 
    { 
     this.name=name; 
    } 
    public void setUrl(String url) 
    { 
     this.name=url; 
    } 

    public void setcategory(String category) 
    { 
     this.category=category; 
    } 

} 

Answer 1

檢查Objects class

public void setUrl(String url){ 
    this.name=url; 
} 

是不是應該

public void setUrl(String url){ 
    this.url=url; 
} 

Answer 2

您添加setter方法爲類型

public void setType(String type) 
{ 
    this.type =type ; 
}
