但之前利用Debug，发现下面两项debug数据都正常，为啥不能正常进入相机预览程序呢
//手机支持预览图片尺寸集合
List<Camera.Size>pictureList = parameters.getSupportedPictureSizes();
//手机支持的预览尺寸集合
List<Camera.Size>previewList = parameters.getSupportedPreviewSizes();
以下参数均正确I/System.out: width:------------------------1920, height :-------------1080
I/System.out: width:------------------------1920, height :-------------1080
//设置为当前手机的最大尺寸
parameters.setPictureSize(pictureList.get(2).width,pictureList.get(2).height);
//设置为当前使用手机的最大尺寸
parameters.setPreviewSize(previewList.get(2).width,pictureList.get(2).height);
原因分析：
可能是以下屏幕预览数据设置失败，原因未知，可能是由于特定设备不兼容
//设置为当前手机的最大尺寸
parameters.setPictureSize(pictureList.get(2).width,pictureList.get(2).height);
//设置为当前使用手机的最大尺寸
parameters.setPreviewSize(previewList.get(2).width,pictureList.get(2).height);
解决方案：
移除上述设置代码，启用系统自定义尺寸；或者设置设备支持的预览尺寸，相机程序就出来了
