基本上，这个错误是在以下位置被定位的：

View view = inflater.inflate(R.layout.input, container,false);

这只会在模拟器中发生，而不会发生在手机上。这里出了什么问题？

- PeakGen

Answer 1

检查你的drawable/background_main，也就是你的根布局背景图片 - 当解码位图时，虚拟机会因为内存不足而崩溃。将图片尺寸缩小。

- laalto

---

你好，你是指减小位图的大小吗？ - PeakGen

是的，通过减小图像尺寸即分辨率来减小位图大小。 - laalto

这个答案帮助了我。谢谢 :) - Stephen

我也遇到了同样的问题，我的情况是我的图片大小约为2MB，尺寸大约为4000x3000像素。 - Diogo Garcia

这个答案帮了我很多。事实上，我一直在使用可绘制资源来实现圆角，这导致我的应用程序崩溃。通过这个答案，我得到了线索并找到了确切的问题。 - Ghanshyam Bagul

Answer 2

我的问题在于，我有一个带有颜色为 ?selectableItemBackground 的 <solid> 形状。虽然这是个特殊情况，但我在这里发布它以便其他人不会犯同样的错误。

- jobbert

Answer 3

问题的原因是因为 *drawable/background_main* 包含了一张高分辨率的图片。因此，当它被加载时，虚拟机内存不足。

所以最好的方法是减小图片的大小或分辨率。

- Piyush

Answer 4

您正在片段中使用此布局，而不是在活动中使用。还有另一个异常OutOfMemory，您的背景图片非常大，请尝试缩小它。

- kalyan pvs

Answer 5

对于那些遇到这个问题的人：有一些情况可能会导致应用程序崩溃。我看到了这些情况中最常见的几种。

1- 使用?selectableItemBackground可能会导致此问题。

2- 如果使用大型图像（或其他）使应用程序出现错误，例如“分配失败”等，当硬件加速开启时会发生这种情况。在这种情况下，您可以将其设置为关闭，并在清单（应用程序元素）中使用large-heap。

3- 如果您有一个在v-21分支中的drawable，并且您在低于21的设备上运行应用程序，也可能会导致此问题。

祝你好运！ https://stacklearn.ir

- Hossein Karami

Answer 6

可能真正的罪魁祸首是由于java.lang.OutOfMemoryError：位图大小超过VM预算。尝试使用较小的图像来查看是否存在与内存相关的问题。 查看以下链接以了解类似问题的示例：

java.lang.OutOfMemoryError：bitmap size exceeds VM budget - android - how many images？ 和 从外部存储加载位图时的OutOfMemory异常

- M D

Answer 7

尝试使用不同分辨率的图片，例如 mdpi、hdpi、xhdpi。如果仅使用高分辨率的图片，则可能会导致低分辨率手机崩溃。

- Tushar Saha

Answer 8

我已经通过减小所有 XML 文件中 .png 按钮的尺寸来解决了相同的问题。

- Ivan Aracki

Answer 9

在我的情况下，我正在使用来自

drawable-v24

的可绘制对象，当我将其移动到

drawable

时，它对我起作用了。

- Abd-Elwahab Zayed

Answer 10

嗯，在我的情况下，答案在xml设计中，冲突android:backgroundTint和android:tint

我设计了一个像这样的FloatinActionButton：

<android.support.design.widget.FloatingActionButton
                    android:id="@+id/fa_close_patient"
                    android:layout_width="50dp"
                    android:layout_height="50dp"
                    android:scaleX="0.8"
                    android:scaleY="0.8"
                    android:layout_alignParentEnd="true"
                    android:layout_centerVertical="true"
                    android:layout_gravity="right"
                    android:layout_marginEnd="30dp"
                    android:backgroundTint="@color/white"
                    android:src="@drawable/ic_close_black_24dp"
                    android:tint="@color/colorPrimaryDark" />

这个没问题，但是API > 23

如果你的设计是针对API_LEVEL < 23的，那么这就是解决方法

<android.support.design.widget.FloatingActionButton
                    android:id="@+id/fa_close_patient"
                    android:layout_width="50dp"
                    android:layout_height="50dp"
                    android:scaleX="0.8"
                    android:scaleY="0.8"
                    android:layout_alignParentEnd="true"
                    android:layout_centerVertical="true"
                    android:layout_gravity="right"
                    android:layout_marginEnd="30dp"
                    app:backgroundTint="@color/white"
                    android:src="@drawable/ic_close_black_24dp"/>

希望我能帮到你，

祝好！
