App force在加载gridview activity时关闭(java.lang.OutOfMemoryError)

Question

在我的主活动中有一个按钮，当它被点击时，它会导致我的GridView活动，但应用程序强制关闭。
我的activity_gridview.xml文件:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.myapps.gridviewexample.GridViewActivity"
android:padding="4dp">
    <GridView
        android:id="@+id/gridview"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:numColumns="3"
        android:columnWidth="150dp"
        android:horizontalSpacing="10dp"
        android:verticalSpacing="10dp"
        android:gravity="center"
        >
    </GridView>
</LinearLayout>

对于遇到大图像问题的人，请查看谷歌文档有效加载大位图，了解如何加载大图像而不会出现OutOfMemoryError。还可以看看Adam Stelmaszczyk的代码，它修复了同样的问题。
