推荐答案

您可以设置位图作为使用的 WallpaperManager 。它定义了方法<一href=\"http://developer.android.com/reference/android/app/WallpaperManager.html#setBitmap%28android.graphics.Bitmap%29\"相对=nofollow> setBitmap（）它允许你设置位图作为墙纸。

You can set a Bitmap as a wallpaper using the WallpaperManager. It defines a method setBitmap() which allows you to set the bitmap as wallpaper.

然而，要做到这一点，你需要设置在清单中定义墙纸的权限。

However, to do that, you need the permission to set the wallpaper to be defined in the manifest.

如何将我的位图发送到GALLARY 结果
您需要创建相应的扩展名的文件，然后使用 COM $ p $（PSS）方法将其写入该文件。结果
这里是一个快速code，我从另外一个答案承担了这样：

how can i send my bitmap to gallary
You need to create a file with appropriate extension and then use the compress() method to write it to that file.
Here is a quick code that I took from another answer on SO:

try {
       FileOutputStream out = new FileOutputStream(filename);
       bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
} catch (Exception e) {
       e.printStackTrace();
}
