java - 过多的 ImageButton 会使应用程序崩溃

Question

在我的 Android 应用程序中，我必须在选项卡式 Activity 的第一个 fragment 中显示大约 43 个 ImageButton，在另一个中显示其他不同的 43 个。第一个工作正常，当我添加应用程序崩溃的第二个 fragment 时。不仅如此，如果我想显示应用程序崩溃前从未使用过的特定图像，则单击我的 ImageButton 之一。

我的可绘制文件夹中的图像有 1MB(共 159 张图像)，所以我真的不知道它是否太多了。

这是出现的错误提示:

非常感谢您。

将此粘贴​​到 list 文件中:-

android:largeHeap="真"

另请阅读:http://dwij.co.in/increase-heap-size-of-android-application/

例子:-

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