的TextView不滾動水平模式

Question

這裏是我的一個Android應用XML：

<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:layout_weight="5" 
    android:background="@drawable/gradient" 
    android:gravity="fill_horizontal" 
    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=".PNRActivity" > 

    <EditText 
     android:id="@+id/pnr_num" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:ems="10" 
     android:gravity="top|center" 
     android:hint="@string/pnr_number" 
     android:inputType="number" 
     android:maxLength="10" > 

     <requestFocus /> 
    </EditText> 

    <LinearLayout 
     android:id="@+id/linearLayout1" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:orientation="horizontal" 
     android:paddingTop="45dip" > 

     <Button 
      android:id="@+id/btnStatus" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_weight="1" 
      android:background="@drawable/btn_pnr" 
      android:text="@string/btnGetStatus" /> 

     <TextView 
      android:id="@+id/centerPoint" 
      android:layout_width="5dip" 
      android:layout_height="wrap_content" 
      android:paddingTop="15dip" 
      android:text="" /> 

     <Button 
      android:id="@+id/btnClear" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_weight="1" 
      android:background="@drawable/btn_pnr" 
      android:text="@string/btnClear" /> 
    </LinearLayout> 

    <TextView 
     android:id="@+id/txtOutput" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_alignLeft="@+id/linearLayout1" 
     android:layout_alignRight="@+id/linearLayout1" 
     android:layout_below="@+id/linearLayout1" 
     android:layout_marginTop="20dp" 
     android:textAppearance="?android:attr/textAppearanceMedium" 
     android:maxLines = "10" 
     android:text="@string/txtOut" 
     android:scrollbars = "vertical" 
     android:freezesText="true" 
     android:background="@drawable/border" 
     android:padding="10dip" /> 

</RelativeLayout> 

我想要的TextView與ID爲txtOutput滾動。我做到這一點：

textView.setMovementMethod(new ScrollingMovementMethod()); 

然而在水平方向滾動不起作用！ 另外我使用freezesText使文本以水平佈局顯示。但水平滾動仍然不起作用。 我該如何使它工作？

從相對佈局的水平滾動視圖更改佈局，以你的佈局，所以......
