渲染错误在ExpandableTextView

Question

我不知道为什么我有渲染错误加入ExpandableTextView

<com.ms.square.android.expandabletextview.ExpandableTextView 
     android:id="@+id/expand_text_view" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_toRightOf="@+id/first_linear" 
     expandableTextView:maxCollapsedLines="4" 
     expandableTextView:animDuration="200"> 

     <TextView 
      android:id="@+id/expandable_text" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:padding="10dp" 
      android:layout_marginTop="5dp"/> 


    </com.ms.square.android.expandabletextview.ExpandableTextView> 

依赖性时，compile 'com.ms-square:expandableTextView:0.1.4'

下面是完整的XML文件：

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v7.widget.CardView

      android:padding="@dimen/activity_horizontal_margin"> 

      <ImageView 
       android:id="@+id/up_vote" 
       android:layout_width="wrap_content"

      <TextView

       android:contentDescription="@string/accepted" 
       android:scaleType="fitXY" 
       android:src="@drawable/correct" /> 

     </LinearLayout> 

     <com.ms.square.android.expandabletextview.ExpandableTextView 
      xmlns:expandableTextView="http://schemas.android.com/apk/res-auto" 
      android:id="@+id/expand_text_view"

      expandableTextView:animDuration="200"> 

      <TextView

       android:layout_marginTop="5dp"/> 


     </com.ms.square.android.expandabletextview.ExpandableTextView> 

    </RelativeLayout> 

</android.support.v7.widget.CardView>

也许你错过了命名空间错误。尝试使用这一个 你可以去here的解释。

<com.ms.square.android.expandabletextview.ExpandableTextView 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:expandableTextView="http://schemas.android.com/apk/res-auto" 
    android:id="@+id/expand_text_view" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    expandableTextView:maxCollapsedLines="4" 
    expandableTextView:animDuration="200"> 
    <TextView 
     android:id="@id/expandable_text" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginLeft="10dp" 
     android:layout_marginRight="10dp" 
     android:textSize="16sp" 
     android:textColor="#666666" /> 
    <ImageButton 
     android:id="@id/expand_collapse" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_margin="16dp" 
     android:layout_gravity="right|bottom" 
     android:background="@android:color/transparent"/>
