將Spinner擴展爲添加索引，錯誤膨脹類

我需要向Spinner添加兩個索引，所以我創建了一個Spin類擴展Spinner。現在在XML文件中，我使用了Spin類的完整路徑名，但它給了我「路徑中沒有找到類」和「錯誤膨脹類」錯誤。下面是代碼：將Spinner擴展爲添加索引，錯誤膨脹類

public class AcceptTimetable extends Activity 
{ 
class Spin extends Spinner 
{ 
    int i, j; 
    public Spin(Context context) 
    { 
     super(context); 
    } 

    public Spin(Context context, AttributeSet attrs) 
    { 
     super(context, attrs); 
    } 

    public Spin(Context context, int mode) 
    { 
     super(context, mode); 
     // TODO Auto-generated constructor stub 
    } 

    public Spin(Context context, AttributeSet attrs, int defStyle, int mode) 
    { 
     super(context, attrs, defStyle, mode); 
     // TODO Auto-generated constructor stub 
    } 

    public Spin(Context context, AttributeSet attrs, int defStyle) 
    { 
     super(context, attrs, defStyle); 
     // TODO Auto-generated constructor stub 
    } 

    public void setIndices(int a, int b) 
    { 
     i=a; 
     j=b; 
    } 

    public int getRow() 
    { return i; } 

    public int getColumn() 
    { return j; } 
} 

Spin hours[][]=new Spin[6][6]; 

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.accept_timetable); 

    hours[0][0]=(Spin)findViewById(R.id.ttmon1); 
//error at this line 


}

下面是XML（只是相關部分）：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context=".AcceptTimeTable" > 

<TextView 
    android:id="@+id/entertt" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="Enter the time table:" /> 

<HorizontalScrollView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/entertt" >" 

<TableLayout 
    android:id="@+id/tableLayout1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:paddingTop="15dp" 
    android:layout_below="@id/entertt" > 

    <TableRow 
     android:id="@+id/monday" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="match_parent" 
      android:text="Mon:" /> 

     <AcceptTimetable.Spin 
      android:id="@+id/ttmon1" 
      android:layout_width="wrap_content" 
      android:layout_height="match_parent"/>

的包是「com.example.bunkmaster」，並且代替使用「AccpetTimetable.Spin 「，即使我說」com.example.bunkmaster.AcceptTimetable.Spin「，它也會給出相同的錯誤。只是「旋轉」也給出了相同的錯誤。我是Android新手，無法理解這一點，請幫助。

這裏是堆棧跟蹤，當我開始AcceptTimetable活動：

我想通了，夥計們。我在自己的java文件中定義了Spin類，並在XML中使用了「com.example.bunkmaster.Spin」。像魅力一樣工作^ _^
