1. 打开recovery串口打印调试

修改bootable/recovery/Android.mk文件,将日志打印重定向到串口,方便调试.

2. 修改代码

旋转UI代码参考了:Android O恢复出厂设置时，图标和屏的方向不一致;
修改当前设备的BoardConfig.mk,定义需要旋转的角度:

BOARD_RECOVERY_UI_ROTATION := 270

修改bootable/recovery/minui/Android.mk,添加以下代码:

+ifeq ($(strip $(BOARD_RECOVERY_UI_ROTATION)), 0)
+  LOCAL_CFLAGS += -DBOARD_RECOVERY_UI_ROTATION_0
+else
+ifeq ($(strip $(BOARD_RECOVERY_UI_ROTATION)), 90)
+  LOCAL_CFLAGS += -DBOARD_RECOVERY_UI_ROTATION_90
+else
+ifeq ($(strip $(BOARD_RECOVERY_UI_ROTATION)), 180)
+  LOCAL_CFLAGS += -DBOARD_RECOVERY_UI_ROTATION_180
+else
+ifeq ($(strip $(BOARD_RECOVERY_UI_ROTATION)), 270)
+  LOCAL_CFLAGS += -DBOARD_RECOVERY_UI_ROTATION_270
+else
+  LOCAL_CFLAGS += -DBOARD_RECOVERY_UI_ROTATION_0
+endif
+endif
+endif
+endif
+

bootable/recovery/minui/graphics_fbdev.cpp添加旋转方向代码:

static GRSurface *gr_rotate_draw = NULL;
#define swap(a, b)             \do                         \{                          \typeof(a) __tmp = (a); \(a) = (b);             \(b) = __tmp;           \} while (0)static GRSurface *rotate_surface_init(GRSurface *surface)
{static GRSurface *rotateSurface = (GRSurface *)malloc(sizeof(GRSurface));if (rotateSurface == NULL){return NULL;}memcpy(rotateSurface, surface, sizeof(GRSurface));#if defined(BOARD_RECOVERY_UI_ROTATION_90) || defined(BOARD_RECOVERY_UI_ROTATION_270)swap(rotateSurface->width, rotateSurface->height);rotateSurface->row_bytes = rotateSurface->width * rotateSurface->pixel_bytes;
#endifrotateSurface->data = (unsigned char *)malloc(rotateSurface->height * rotateSurface->row_bytes);if (rotateSurface->data == NULL){free(rotateSurface);return NULL;}memset(rotateSurface->data, 0, rotateSurface->height * rotateSurface->row_bytes);return rotateSurface;
}static void rotate_surface_exit(GRSurface *surface)
{if (surface){if (surface->data)free(surface->data);free(surface);}surface = NULL;
}static void rotate_surface_0(GRSurface *dst, GRSurface *src)
{memcpy(dst->data, src->data, src->height * src->row_bytes);
}static void rotate_surface_270(GRSurface *dst, GRSurface *src)
{int v, w, h;unsigned int *src_pixel;unsigned int *dst_pixel;for (h = 0, v = src->width - 1; h < dst->height; h++, v--){for (w = 0; w < dst->width; w++){dst_pixel = (unsigned int *)(dst->data + dst->row_bytes * h);src_pixel = (unsigned int *)(src->data + src->row_bytes * w);*(dst_pixel + w) = *(src_pixel + v);}}
}static void rotate_surface_180(GRSurface *dst, GRSurface *src)
{int v, w, k, h;unsigned int *src_pixel;unsigned int *dst_pixel;for (h = 0, k = src->height - 1; h < dst->height && k >= 0; h++, k--){dst_pixel = (unsigned int *)(dst->data + dst->row_bytes * h);src_pixel = (unsigned int *)(src->data + src->row_bytes * k);for (w = 0, v = src->width - 1; w < dst->width && v >= 0; w++, v--){*(dst_pixel + w) = *(src_pixel + v);}}
}static void rotate_surface_90(GRSurface *dst, GRSurface *src)

}

3. 编译

执行以下命令,可以单独编译recovery,但是需要重新刷入recovery.img进行测试验证.

$ source build/envsetup.sh
$ touch bootable/recovery/minui/*
$ make recoveryimage -j8
