如何在Android中的另一个布局xml文件中创建Button对象

您好，我创建了一个Android应用程序，在其中使用CustomAdapter在ListView中添加了一些按钮和图像。

我的文件结构是：

layout
   [1] album ->List View
   [2] album_list -> Button

那么我如何创建Button对象呢？

我的代码是：

album.xml

<GridLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:columnCount="1" >

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_column="0"
        android:layout_gravity="left|top"
        android:layout_row="0" >
    </ListView>
</GridLayout>

album_list.xml

<RelativeLayout
            android:id="@+id/RelativeLayout001"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:columnCount="2"
            android:orientation="horizontal" >



            <Button
                android:id="@+id/btn_eng"
                style="?android:attr/buttonStyleSmall"
                android:layout_width="100px"
                android:layout_height="31px"
                android:layout_marginLeft="11dp"
                android:layout_marginRight="17dp"
                android:layout_marginBottom="5dp"
                android:layout_marginTop="35dp"
                android:layout_alignTop="@+id/btn_hindi"                    
                android:layout_alignBottom="@+id/ImageView12"
                android:layout_alignLeft="@+id/ImageView12"
                android:background="@drawable/normal"
                android:text="ENG"
                android:textColor="@android:color/white" />

            <TextView
                android:id="@+id/tv_albumname"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@+id/tv_go"
                android:layout_alignTop="@+id/iv_album_image"
                android:layout_marginLeft="2dp"
                android:layout_marginTop="2dp"
                android:text="Album Name"
                android:textAppearance="?android:attr/textAppearanceSmall"
                android:textColor="@android:color/white" />

            <Button
                android:id="@+id/btn_hindi"
                style="?android:attr/buttonStyleSmall"
                android:layout_width="100px"
                android:layout_height="31px"
                android:layout_marginTop="7dp"
                android:layout_marginRight="17dp"                   
                android:layout_alignTop="@+id/ImageView12"                  
                android:layout_alignLeft="@+id/btn_eng"
                android:background="@drawable/normal"
                android:text="HINDI"

                android:textColor="@android:color/white" />

        </RelativeLayout>
