我正在使用 Swipey-ViewPagerIndicator。我有三个片段。这些片段的布局包含 ImageView。这是fragment_swipeytab.xml：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffffff"
android:id="@+id/RootView">
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</FrameLayout>
以编程方式为三个片段设置图像。这是 SwipeyTabFragment.java：

问题是 ANR - 当我滑动片段时出现 OutOfMemory 错误。当只有三个片段中只有一个图像（也是相同的资源 R.drawable.both ）时，为什么会发生 OutOfMemory ？如何解决？
