Android calls camera API to take pictures and cause picture distortion

Since basically all Android phones support images with a ratio of 4:3 and 16:9, sometimes the custom Surfaceview size does not meet these two proportions and will deform.

Another situation is that the default previewsize and the ratio of our view will also cause deformation; the solution is from params.getsupportedpreviewsizes () Choose the appropriate proportions and then params.setpreviewsize (), at which point the size of the preview is set, and the resulting photo does not matter, if you want to set the scale of the resulting photo, You can select the appropriate scale from the params.getsupportedpicturesizes () and then Params.setpicturesize ().
