`我使用的是API23，应用程序的最小API是16。那么我应该怎么做来修复这个错误
我试过墙纸管理器但是出错了
这是密码
case R.id.button:
InputStream yeaaa =getResources().openRawResource(toPhone);
Bitmap Whatever = BitmapFactory.decodeStream(yeaaa);
WallpaperManager myWallpaper =WallpaperManager.getInstance(this);
try{
myWallpaper.setBitmap(Whatever);
} catch (IOException e) {
e.printStackTrace();
}
break;

最佳答案
你可以用
WallpaperManager.setBitMap()
因为setWallpaper（）已被弃用。
如果有图像uri，请使用以下命令：
wallpaperManager = WallpaperManager.getInstance(this);
wallpaperDrawable = wallpaperManager.getDrawable();
mImageView.setImageURI(imagepath)
