Hi you can use this code if You have Image path.
嗨，如果您有图像路径，则可以使用此代码。
is = new FileInputStream(new File(imagePath));
bis = new BufferedInputStream(is);
Bitmap bitmap = BitmapFactory.decodeStream(bis);
Bitmap useThisBitmap = Bitmap.createScaledBitmap(
bitmap, parent.getWidth(), parent.getHeight(), true);
bitmap.recycle();
if(imagePath!=null){
System.out.println("Hi I am try to open Bit map");
wallpaperManager = WallpaperManager.getInstance(this);
wallpaperDrawable = wallpaperManager.getDrawable();
wallpaperManager.setBitmap(useThisBitmap);
if you have image URI then use this
如果您有图像 URI，则使用它
wallpaperManager = WallpaperManager.getInstance(this);
wallpaperDrawable = wallpaperManager.getDrawable();
mImageView.setImageURI(imagepath);
Let me know if there is any issue .
让我知道是否有任何问题。

If you have the image URL you can open the resource it represent using the stream(abstraction):
new URL("your.image.url.com").openStream(). This method call will return an object of type InputStreamwhich you can pass as an argument to setStream()method.
如果您有图像 URL，则可以使用 stream(abstraction): 打开它代表的资源
new URL("your.image.url.com").openStream()。此方法调用将返回一个类型的对象InputStream，您可以将其作为参数传递给setStream()方法。
If you dont want to specify a stream directly, you can open the remote stream, create a Bitmap and then either use a WallpaperManagerinstance or do a context.setWallpaper(bitmap)(this is deprecated) to set your bitmap as the wallpaper.
如果不想直接指定流，可以打开远程流，创建位图，然后使用WallpaperManager实例或执行context.setWallpaper(bitmap)（已弃用）将位图设置为墙纸。
For reference take a look at thisthread.
