推荐答案
Android的相机有两种独立的设置为 previewSize 和 pictureSize 。它们可以具有不同的纵横比，也。例如。
Android camera has two independent settings: previewSize and pictureSize. They may have different aspect ratios, too. E.g.
previewSize=1920x1080
pictureSize=4200x2800
相机不扭曲的形象，它作物了。
The camera does not distort the image, it crops it.
如果你想保留的同一视场中捕获的图片作为你有你的取景器屏幕上，你应该选择两个相同的纵横比。即使这并不能保证捕捉将保留看法完全相同字段（例如，由于集中调整）。
If you want to keep the same field of view in your captured picture as you have on your viewfinder screen, you should choose same aspect ratios for both. Even this does not guarantee that the capture will keep exactly same field of view (e.g. due to focus adjustments).
请注意，您必须选择相机支持的preVIEW大小和图像尺寸。 Android的API包括的 的和的 的
Note that you must choose the preview size and picture size supported by your camera. Android API includes getSupportedPictureSizes() and getSupportedPreviewSizes().
