【问题讨论】：

您的堆栈跟踪应该有更多内容，包括一系列“由”部分。
就是这样......我的堆栈中没有部分原因:(
您是否尝试使用百分比设置图像宽度？
有，你把它剪掉。它说它正在发送一个信号，但你没有复制那部分。

【解决方案1】：

听起来像是内存问题或低版本的兼容性

使用记忆工具，例如谷歌浏览器内存快照 adb shell dumpsys meminfo com.example.appname

为了兼容性，您可以尝试降低 gradle 中的 sdk 版本

【解决方案2】：

您的应用使用了多少内存？每个设备都有自己的最大允许内存，正在运行的应用程序可以使用。您可以使用以下代码行来检查您正在运行的特定设备的最大限制是多少。由于显而易见的原因，旧设备的这个数字较低，而新设备的这个数字较高。

Runtime rt = Runtime.getRuntime();
long maxMemory = rt.maxMemory();
Log.i("Android", "maxMemory:" + Long.toString(maxMemory / 1000000) + "Mb");

这将返回您的应用可以使用的最大 RAM 量（以 MB 为单位）。然后，您可以轻松地将这个数字与 Android Studio 的 Android Profiler 部分中看到的数字进行比较。从那里你应该能够找出问题所在。
