java - 过多的 ImageButton 会导致应用程序崩溃

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 fragment 中显示其他不同的 43 个。第一个工作正常，当我添加第二个 fragment 时，应用程序崩溃了。不仅如此，如果我想显示应用程序崩溃之前从未使用过的特定图像，单击其中一个图像按钮。

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

这是出现的错误信息:

提前非常感谢您。

将其粘贴到 list 文件中:-

android:largeHeap="true"

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

示例:-

<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>
