滾動型是不可見的

Question

下面給出一個代碼塊，重複5時在我的佈局

<RelativeLayout android:layout_alignParentLeft="true" 
      android:layout_below="@+id/button_clock_homescreen" 
      android:layout_width="fill_parent" android:id="@+id/rel1" 
      android:layout_marginTop="40dp" android:layout_height="70dp"> 
      <ImageView android:id="@+id/image_sound_selected" 
       android:visibility="visible" android:layout_marginLeft="10dp" 
       android:src="@drawable/airpurifier_cat" android:layout_width="60dp" 
       android:layout_height="60dp"></ImageView> 
      <LinearLayout android:orientation="vertical" 
       android:layout_height="fill_parent" android:layout_alignParentTop="true" 
       android:layout_toRightOf="@+id/image_sound_selected" 
       android:layout_marginLeft="10dp" android:layout_width="fill_parent"> 
       <LinearLayout android:id="@+id/LinearLayout02" 
        android:layout_width="fill_parent" android:layout_height="wrap_content"> 
        <Button android:background="@drawable/soundselect" 
         android:layout_width="180dp" android:layout_height="40dp" 
         android:textColor="#FFF" android:text="Select Sound" android:id="@+id/button_soundselect1"></Button> 
        <Button android:layout_width="40dp" android:background="@drawable/ipod_play" 
         android:id="@+id/button_player1_play" android:layout_height="30dp"></Button> 

       </LinearLayout> 
       <LinearLayout android:id="@+id/LinearLayout01" 
        android:layout_height="wrap_content" android:layout_width="fill_parent"> 
        <ImageButton android:layout_width="wrap_content" 
         android:layout_height="wrap_content" android:background="@drawable/pitch_balance" 
         android:id="@+id/imagebutton_home_player1_setting"> 
        </ImageButton> 
        <SeekBar android:indeterminateDrawable="@drawable/volumebutton" 
         android:id="@+id/seekbar_player1" android:soundEffectsEnabled="true" 
         android:layout_height="wrap_content" android:layout_gravity="center_vertical" 
         android:layout_width="140dp"></SeekBar> 

       </LinearLayout> 



      </LinearLayout> 


     </RelativeLayout> 
     <LinearLayout android:layout_height="wrap_content" 
      android:id="@+id/linearLayout2" android:layout_width="fill_parent"> 
      <LinearLayout android:layout_width="fill_parent" 
       android:id="@+id/linearlayout_home_mediaplayer1_setting" 
       android:visibility="invisible" android:layout_height="40dp"> 
       <Button android:layout_width="40dp" 
        android:layout_marginLeft="20dp" android:layout_height="20dp" 
        android:background="@drawable/ipod_pause" android:id="@+id/button_player1_setting_playpause"></Button> 
       <Button android:layout_width="50dp" android:background="@drawable/ipod_fforward" 
        android:layout_marginLeft="20dp" android:layout_height="20dp" 
        android:id="@+id/button_player1_setting_forward"></Button> 
       <Button android:layout_width="50dp" 
        android:layout_marginLeft="20dp" android:background="@drawable/ipod_bback" 
        android:id="@+id/button_player1_setting_reverse" 
        android:layout_height="20dp"></Button> 
       <Button android:background="@drawable/ipod_loop_off" 
        android:layout_width="50dp" android:layout_marginLeft="20dp" 
        android:id="@+id/button_player1_setting_loopplay" 
        android:layout_height="20dp"></Button> 
      </LinearLayout> 
     </LinearLayout> 

我已經以這種方式在此塊上應用滾動視圖，我在一個線性佈局封閉這五個重複的塊，並把在寬度爲&高度：fill_parent的滾動視圖內。

這是由此得到的代碼

<ScrollView android:id="@+id/ScrollView01" 
    android:layout_width="fill_parent" android:layout_height="620px" android:fillViewport="true" 
    android:measureAllChildren="true" android:scrollbars="vertical"> 
    <LinearLayout android:id="@+id/LinearLayout02" 
     android:layout_width="fill_parent" android:orientation="vertical" android:layout_height="fill_parent"> 

     <!-- PLAYER ONE START --> 
     <RelativeLayout android:layout_alignParentLeft="true" 
      android:layout_below="@+id/button_clock_homescreen" 
      android:layout_width="fill_parent" android:id="@+id/rel1" 
      android:layout_marginTop="40dp" android:layout_height="70dp">

       android:layout_height="60dp"></ImageView> 
      <LinearLayout android:orientation="vertical" 
       android:layout_height="fill_parent" android:layout_alignParentTop="true"

       </LinearLayout> 



      </LinearLayout>

     </LinearLayout> 
     </LinearLayout>

我感到困惑的是問題，滾動型是不可見的...

嘗試將此標記添加到您的滾動型
