如何获取相机的屏幕尺寸
我有一个应用程序，可以在相机拍摄的位图上添加效果。它在我的 Galaxy 门户上运行良好，但在 HTC Desire 上尝试该应用程序时，jpeg 图像很小。如何设置最终显示的图片尺寸为全屏尺寸？在 Galaxy 上，我使用了 BitmapFacory.Options 样本大小=1，这使得图像与捕获的图像大小相同，但在不同的手机上，这不起作用。谢谢。
I've an app that places an effect on a bitmap from a camera shot. it works fine on my Galaxy portal but when trying the app on HTC Desire the jpeg image is small. How can i set the picture size that is ultimately displayed to the full size of the screen? On the Galaxy i've used BitmapFacory.Options sample size=1, this makes the image the same size as the one captured, but on different phones this doesn't work. thanks.

捕获尺寸和预览尺寸之间存在差异（屏幕尺寸永远不会改变，这是特定于设备的），所以我假设您正在谈论捕获尺寸。
您只能选择相机支持的拍摄尺寸选择支持的图像尺寸 所以我想您可以选择相机支持的最大尺寸，但如果您想标准化尺寸（在每个相机上制作相同的尺寸），那么您必须根据需要向上或向下缩放生成的图像。
但我想知道这是否是您真正想要的，或者您是否试图将图像放置在特定位置（例如捕获图像的中心）并可能将覆盖图像缩放到捕获图像的百分比？
There is a difference between the capture size and the preview size (the screen size never changes that's device specific) so I am assuming you are talking about the capture size.
You can only select a capture size that is supported by the camera Selecting Supported Image Sizes so I suppose you could select the highest size that a camera supports, but if you want to normalize the size (make same on each camera) then you would have to scale the resulting image up or down dependent.
But I am wondering if this is what you are really after, or are you trying to place the image in a specific location (like the center of the captured image) and possibly scaling the overlaid image to a percentage of the captured image?
