<!-- Current queue drawer --> 
<RelativeLayout 
    android:id="@+id/main_activity_queue_drawer" 
    android:layout_width="320dp" 
    android:layout_height="match_parent" 
    android:layout_gravity="end" > 

    <TextView 
     android:id="@+id/empty_queue_text" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerHorizontal="true" 
     android:layout_centerVertical="true" 
     android:text="@string/queue_is_empty" 
     android:layout_marginLeft="25dp"

<com.mobeta.android.dslv.DragSortListView 
      xmlns:dslv="http://schemas.android.com/apk/res/com.jams.music.player" 
      android:id="@+id/queue_list_view" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:drawSelectorOnTop="true" 
      dslv:click_remove_id="@+id/remove_song_from_queue" 
      dslv:drag_enabled="true" 
      dslv:drag_handle_id="@+id/playlists_flipped_handle" 
      dslv:drag_scroll_start="0.33" 
      dslv:drag_start_mode="onDown" 
      dslv:float_alpha="0.6" 
      dslv:max_drag_scroll_speed="0.8" 
      dslv:remove_enabled="true" 
      dslv:remove_mode="clickRemove" 
      dslv:slide_shuffle_speed="0.5" /> 

从小窗口中提到移除这个名称空间，并将其添加到父布局。下面xmlns:dslv="http://schemas.android.com/apk/res/com.jams.music.player

提到的事情，你应该在attrs.xml提到资源

  click_remove_id 
      drag_enabled 
      drag_handle_id 
      drag_scroll_start 
      drag_start_mode 
      float_alpha 
      max_drag_scroll_speed 
      remove_enabled 
      remove_mode 
      slide_shuffle_speed 

Answer 2

Boopathi的答案是正确的。

它只需要这些属性的数据类型。在attrs.xml文件中添加下面提到的代码

<attr name="click_remove_id" format="string" /> 
    <attr name="drag_enabled" format="boolean" /> 
    <attr name="drag_handle_id" format="integer" /> 
    <attr name="drag_scroll_start" format="float" /> 
    <attr name="drag_start_mode" format="string" /> 
    <attr name="float_alpha" format="float" /> 
    <attr name="max_drag_scroll_speed" format="float" /> 
    <attr name="remove_enabled" format="boolean" /> 
    <attr name="remove_mode" format="string" /> 
    <attr name="slide_shuffle_speed" format="float" />
