Bitmap类型格式问题

同样一张图片在2.2模拟器上格式为RGB565

但是在真机2.3.4上格式却为RGB8888

酷毙额

typedef struct 
{
    uint8_t alpha;
    uint8_t red;
    uint8_t green;
    uint8_t blue;
} argb;

enum AndroidBitmapFormat {
    ANDROID_BITMAP_FORMAT_NONE      = 0,
    ANDROID_BITMAP_FORMAT_RGBA_8888 = 1,
    ANDROID_BITMAP_FORMAT_RGB_565   = 4,
    ANDROID_BITMAP_FORMAT_RGBA_4444 = 7,
    ANDROID_BITMAP_FORMAT_A_8       = 8,
};

注意RGBA_8888
