android - Viewflipper Receiver 在 2.1 和 2.2 中方向改变时未注册错误

Question

我正在使用 viewflipper 进行手势识别，在 2.0 和之前的版本中一切正常，但在 2.2 和 2.1 中它抛出异常，如“java.lang.IllegalArgumentException: Receiver not registered: android.widget.ViewFlipper”下面是完整的调试跟踪。

There is issue on Google related to this bug 6191.

而且那里提到的解决方案似乎只有在您通过代码创建 ViewFlipper 时才有效，但在我的情况下，我使用 XML 中的 ViewFlipper，这是我的布局文件，所以我不能使用提到的解决方案来扩展我尝试使用的 ViewFlipper延迟似乎没有任何作用。

我被这个问题困住了，非常感谢任何帮助。

下面是我的布局代码。

<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/flipper"
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent">
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/parentView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/listingBG">
        <TextView 
                android:id="@+id/statusMessage" 
                android:layout_height="fill_parent" 
                android:layout_width="fill_parent"
                style="@style/TextLabel.Normal" android:visibility="gone" 
                android:text="No result" android:padding="15dp" android:gravity="center_horizontal"/>
        <ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent" android:scrollbars="none" android:id="@+id/scrollView" >
            <RelativeLayout android:id="@+id/parentItemView" android:layout_height="wrap_content" android:layout_width="fill_parent">
            </RelativeLayout>
        </ScrollView>
    </LinearLayout>
</ViewFlipper>

Answer 1

您可以扩展 ViewFlipper 并在 xml 布局文件中使用新类的全名(带包):


<com.yourpackage.FixedViewFlipper>
...
</com.yourpackage.FixedViewFlipper>


您甚至可以使用像 res/layout-v7 这样的布局目录名称为 2.1 和 2.2 版本创建不同的 xml 文件。和 res/layout-v8 .
