Question

我正在使用带有PagerAdapter的自定义视图寻呼机，当我有＆＃34;不要保持活动时，我会遇到以下崩溃问题。打开了：

来自我的PagerAdapter的

instantiateItem看起来像这样：

public class CustomAdapter extends PagerAdapter {

public CustomAdapter(Context context) {
    this.mContext = context;
}

@Override
public Object instantiateItem(ViewGroup collection, int position) {
    LayoutInflater inflater = LayoutInflater.from(mContext);
    mViewPagerLayout = inflater.inflate(R.layout.custom_view_pager, collection, false);

    mViewPagerLayout.setTag("pos" + position);
    collection.addView(mViewPagerLayout);
    return mViewPagerLayout;
}

CustomViewPager：

public class CustomViewPager extends ViewPager {

public CustomViewPager(Context context) {
    super(context);
}


// more code

}

正在使用自定义视图寻呼机的xml：

<view xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    class="com.android.lib.views.WrapperView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <com.android.lib.views.CustomViewPager
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_gravity="center_horizontal|bottom"
      android:layout_alignParentBottom="true"
      android:layout_marginBottom="5dp"
      android:clipToPadding="false"
      android:paddingLeft="20dp"
      android:paddingTop="0dp"
      android:paddingBottom="0dp"
      android:paddingRight="20dp"
      android:visibility="gone"
      tools:visibility="visible"/>
 </view>

我在这里查看了解决方案ClassNotFoundException when unmarshalling: android.support.v4.view.ViewPager$SavedState，但这些是片段，但我使用View和PagerAdapter来保持它的重量轻。任何想法我能做什么？

解组时的PagerAdapter ClassNotFoundException：android.support.v4.view.ViewPager $ SavedState
