什么会导致这个XML耗尽内存

Question

我有一个scrollveiw根布局包装一个相对布局与一些Imageview，textviews等。 出于某种原因，在访问此XML文件时，它会占用大量的堆空间。已解决所有lint错误，但仍有问题，这里是代码：

<?xml version="1.0" encoding="utf-8"?>

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    >

    <RelativeLayout 
      android:layout_width="fill_parent"

你的布局文件似乎很大，以至于它可能只是通过这个事实增加了堆的使用量。但如果我不得不指出罪魁祸首，我会选择你的ImageView。请记住，当您加载此布局文件时，所有ImageView都将呈现，如果您的图像文件未经过优化，则可能会出现递增的堆使用情况。

我建议您阅读此参考页，因为您可以确认或放弃这个想法作为罪魁祸首：
