SlidingDrawer를 구현하는 동안 handle 속성이 기존 자식을 참조해야합니다.

Question

SlidingDrawer을 구현하려고합니다. 내 응용 프로그램이 충돌합니다.

XML 파일

<?xml version="1.0" encoding="UTF-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

    <SlidingDrawer 
     android:id="@+id/drawer" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:content="@+id/content" 
     android:handle="@+id/handle" > 
    </SlidingDrawer> 

    <LinearLayout 
     android:id="@+id/contentLayout"

     </include> 

     <ListView 
      android:id="@android:id/list" 
      android:layout_width="fill_parent"

Answer 1

Caused by: java.lang.IllegalArgumentException: The handle attribute is must refer to an existing child. 

android:handle="@+id/handle" 

SlidingDrawer 속성에서

. 하지만 '핸들'이라는 ID를 가진 슬라이딩 서랍의 기존 아이는 없습니다. 핸들 속성에 대한

확인 documentation : 서랍의 손잡이를 나타내는 아이

식별자.

"@ [+] [package :] type : name"또는 "? [package :] [type :] name"형식의 테마 속성에 대한 참조 여야합니다. .

그래서 당신은 같은으로 XML 파일을 수정해야합니다 :

<SlidingDrawer 
     android:id="@+id/drawer" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:content="@+id/content" 
     android:handle="@+id/handle" > 

    <ImageView 
      android:id="@id/handle" 
      android:layout_width="88dip" 
      android:layout_height="44dip" /> 

</SlidingDrawer> 

는 도움이되기를 바랍니다.

Answer 2

SDK에서 SlidingDrawer 코드를 복사하여 프로젝트로 가져 오는 경우 비슷한 문제가 발생했습니다. 내 문제는 레이아웃 파일의 네임 스페이스입니다.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:dd="http://schemas.android.com/apk/res/com.example.actionbarslider" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 


<com.example.actionbarslider.MySlidingDrawer 
    android:id="@+id/drawer" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    dd:content="@+id/mycontent" 
    dd:handle="@+id/handle" 
    dd:orientation="0" > 

    <ImageView 
     android:id="@id/handle" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:background="@drawable/exit_light" /> 

    <LinearLayout 
     android:id="@id/mycontent" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical" > 

     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:padding="20dp" 
      android:text="Hello" 
      android:textSize="20sp" /> 

     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:padding="20dp" 
      android:text="World" 
      android:textSize="20sp" /> 
    </LinearLayout>  

</com.example.actionbarslider.MySlidingDrawer> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Top Drawer"/> 
</LinearLayout> 

참고 : 나는 styleable 속성을 참조하기 위해 내 자신의 네임 스페이스를 만든 표준을 일치 "안드로이드"

내가 제대로 나는이 같은 언급했다 어떤 속성 식별하여 문제를 해결 네임 스페이스. "XMLNS : DD =". ... "

나는이처럼 attrs.xml이 파일에 대해 동일한 일을했다 :

<?xml version="1.0" encoding="utf-8"?> 

<declare-styleable name="MySlidingDrawer"> 

    <!-- Identifier for the child that represents the drawer's handle. --> 
    <attr name="handle" format="reference" /> 

    <!-- Identifier for the child that represents the drawer's content. --> 
    <attr name="content" format="reference" /> 

    <!-- Orientation of the SlidingDrawer. --> 
    <attr name="orientation" format="integer"/> 

    <!-- Extra offset for the handle at the bottom of the SlidingDrawer. --> 
    <attr name="bottomOffset" format="dimension" /> 

    <!-- Extra offset for the handle at the top of the SlidingDrawer. --> 
    <attr name="topOffset" format="dimension" /> 

    <!-- Indicates whether the drawer can be opened/closed by a single tap 
     on the handle. (If false, the user must drag or fling, or click 
     using the trackball, to open/close the drawer.) Default is true. --> 
    <attr name="allowSingleTap" format="boolean" /> 

    <!-- Indicates whether the drawer should be opened/closed with an animation when the user clicks the handle. Default is true. --> 
    <attr name="animateOnClick" format="boolean" /> 
</declare-styleable>  

이제 모든 작업.
