Question

你好，那里的程序员！在一开始我必须说我现在正在学习机器人3天，所以这可能是一些愚蠢的问题，但我依靠你的理解。我正在尝试创建一个简单的Activity，它将是一种DiceRoller。它工作了一段时间，但突然间，当我甚至进入活动时，它开始崩溃。我无法理解错误 - 这就是为什么我在困扰你。

我的XML代码： http://www.wklej.org/id/3118631/

Java代码： http://www.wklej.org/id/3118642/

不得不从我的角色限制的原因中删除代码。

错误日志：

在下面的评论中通过farhan patel的建议学习什么是Glide时，我发现了一个现在正在添加的解决方案

机器人：largeHeap = “真”

进入我的清单文件。它现在看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.daniel.scrolltest3">
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/logo"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:largeHeap="true"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

    </application>

首先，请勿使用fill_parent使用match_parent。大约7年前， fill_parent 重命名为 match_parent 。他们做同样的事情，但不推荐使用 fill_parent 名称。

在我看来，您收到此错误是因为您将所有图片都放入 drawable 文件夹中。此行为会使您的设备重新缩放图像，这会导致分辨率较高的图像出现OutOfMemory错误。

您需要根据屏幕DPI调整所有图片的大小，并将它们放入如下所示的可绘制文件夹中：

抽拉-xxxhdpi
抽拉-xxhdpi
抽拉-xhdpi
抽拉-HDPI
抽拉-MDPI

检查this和this以获取更多信息。
