android 获取类对象(代码片段)

1、定义一个object对象

private static final Object sInstanceLock = new Object();
private static WallpaperColorInfo sInstance;

2、获取方法：

public static WallpaperColorInfo getInstance(Context context) {
        synchronized (sInstanceLock) {
            if (sInstance == null) {
                sInstance = new WallpaperColorInfo(context.getApplicationContext());
            }
            return sInstance;
        }
    }

3、调用：

WallpaperColorInfo wallpaperColorInfo = WallpaperColorInfo.getInstance(this);
