Question

我正在尝试将图像加载到ImageView中并且正在接收OutOfMemoryError。图像根据ViewPager中的特定视图动态显示。但是，在我继续滚动浏览ViewPager之后，图像最终无法加载并导致OutOfMemoryError。

请注意，我在ViewPager中有4个View，并且应用程序似乎在View 2上崩溃。我猜这个图片的大小很大，但我认为Picasso会相应地处理：

毕加索代码：

Picasso.with(getActivity())
    .load(mImageURL)
    .fit()
    .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_CACHE)
    .into((ImageView) rootView.findViewById(R.id.comments_image));

XML

<ImageView
    android:id="@+id/comments_image"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight=".525"
    android:background="@color/black">
</ImageView>

错误

Answer 1

我建议您使用Glide，因为它默认设计用于低成本（和最差硬件）设备。

毕加索和格莱德之间的一个很大区别是，当毕加索的RGB_565时，格莱德的默认格式为ARGB_8888。正如你在下面所看到的，与毕加索相比，它的内存成本要低50％。

Memory cost

但是，如果您不想更改库，可以尝试使用.resize(int, int)方法在Picasso的构建器上调整图像大小。

Answer 2

你做过android：largeheap =＆＃34; true＆＃34;在你最明确的文件中？

<application
    android:name=".MyApplication"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="MyApplication"
    android:largeHeap="true"*
    android:logo="@drawable/logo_for_up"
    android:screenOrientation="portrait"
    android:theme="@style/AppTheme" >
</application>
