它抛出了一个错误，可能是因为您正在运行/测试的设备。我在使用QRScanner时遇到了相同的问题 尝试更改参数。setPreviewFrameRate（60）；setPreviewSize（19201080）；根据您正在使用的设备。

快乐编码不要使用静态预览大小，请尝试使用中介绍的受支持的预览大小
Camera.Parameters=Camera.getParameters（）；
列出customSizes=parameters.getSupportedPreviewSizes（）；
//选择所需的预览大小
Camera.Size customSize=//添加的大小
parameters.setPreviewSize（customSize.width、customSize.height）；
设置参数（参数）；
camera.startPreview（）；
使用这种方法会更安全，因为所有设备都不支持手动大小，而不是使用静态预览大小。请尝试使用中引入的支持预览大小
Camera.Parameters=Camera.getParameters（）；
列出customSizes=parameters.getSupportedPreviewSizes（）；
//选择所需的预览大小
Camera.Size customSize=//添加的大小
parameters.setPreviewSize（customSize.width、customSize.height）；
设置参数（参数）；
camera.startPreview（）；
使用这种方法会更安全，因为所有设备都不支持手动大小您使用的是虚拟设备还是真实设备？我使用的是真实设备？您使用的是虚拟设备还是真实设备？我使用的是真实设备？customSize的值是多少？@User这将是最适合您的应用程序的预览大小使用此'Camera.size customSize=customSize.get（0）；'“customSize”的值是多少？@User它将是最适合您的应用程序的预览大小使用此“Camera.size customSize=customSize.get（0）；”
Camera.Parameters parameters = camera.getParameters();
List<Camera.Size> customSizes = parameters.getSupportedPreviewSizes();
// Choose desired preview size
Camera.Size customSize = //Added size
parameters.setPreviewSize(customSize.width, customSize.height);
camera.setParameters(parameters);
camera.startPreview();
