许多设备中出现的屏幕失真（黑线）

Question

我的设备通过USB线连接到PC很长时间了。当我进入我的应用程序并按下屏幕时，我会看到图像中的黑线。我检查了我的ADB日志

正如在日志系统中试图做“memalloc”“gralloc”!!不确定有什么问题!!请帮忙

使用的设备：三星Galaxy S3

Answer 1

这似乎是设备端的问题。这里变量的变量是我正确的设备吗？两个设备上的代码是相同的（如果我错了，请纠正我），所以关键是要查找S2和S3之间的不同之处（即屏幕密度，显示，api级别）。所以这就是我要做的事情：在另一部手机上试试你的应用程序（可能是你的好友的手机或其他什么），看看会发生什么。而不是试图找到手机的系统属性之间的相似性，试图拼凑出错误的原因。我希望这个帮助能祝你好运！似乎S3正在发生一些事情。我今天才发现这个question。看看this也是
