Android 11.0 Camera 分辨率从高到低排列

路径：packages/apps/Camera2/src/com/android/camera/settings/PictureSizeLoader.java

用 Collections 对相机具备的像素集合数据进行排序。

s2与s1的先后顺序决定：将像素按高度从高到低还是从低到高进行排序
​​​s2.getHeight()-s1.getHeight()​​

private List<Size> computeSizesForCamera(CameraDeviceSelector facingSelector) {
....
+                //wangrui Resolution sort
+                try {

+                        public int compare(Size o1, Size o2) {
+                            if (o1 instanceof Size && o2 instanceof  Size){
