圖Line

我有繪畫線問題如上面一峯。我怎樣才能做到這一點？這是視圖的代碼，我需要實現它。我想我需要使用畫布，但我不確定。感謝您的任何建議！

<RelativeLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center" 
     android:layout_marginTop="@dimen/linear_layout_buttons_margin_top" 
     android:orientation="vertical"> 

     <TextView 
      android:id="@+id/button_from_city" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:layout_marginBottom="4dp" 
      android:layout_marginLeft="60dp" 
      android:layout_marginRight="60dp" 
      android:layout_marginTop="4dp" 
      android:background="@drawable/button_white" 
      android:drawableLeft="@drawable/ic_green" 
      android:drawablePadding="@dimen/dots_white_button_padding" 
      android:drawableStart="@drawable/ic_green" 
      android:gravity="center_vertical" 
      android:hint="@string/from_place" 
      android:padding="@dimen/dots_white_button_padding" 
      android:textColor="@color/color_accent" 
      android:textColorHint="@color/text_view_hint_color"/> 

     <TextView 
      android:id="@+id/button_to_city" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:layout_below="@id/button_from_city" 
      android:layout_marginBottom="4dp" 
      android:layout_marginLeft="60dp" 
      android:layout_marginRight="60dp"
