android – OutOfMemoryError：使用1080 * 1920的图像执行启动页面[复制]

参见英文答案 > Strange out of memory issue while loading an image to a Bitmap object41个
我想在我的Android应用程序中实现启动页面.所以在布局xml中,有一个imageView,而图像文件是一个1080 * 1920的png文件,当运行应用程序时,它会发生OutOfMemoryError错误,我该如何解决？

XML文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/welcome1"/>

</LinearLayout>

错误信息：

解决方法

如果您在drawable文件夹中有welcome1.png,请将其放在drawable-nodpi中.

这是因为drawable被解释为drawable-mdpi,因此当你将它加载到更高密度的手机上时,它将被放大(成为一个巨大的位图).
