             try{
                 getApplicationContext().setWallpaper(Whatever);
             } catch (IOException e) {

             }
             break;

    }
}
}

`我正在使用 API 23，应用程序的最小 API 是 16.So 我应该如何修复错误

我试过墙纸管理器但出现错误这是代码

 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;

Answer 1

此方法自 API 5 起已弃用，您应该改用 WallpaperManager.setBitMap()。

Answer 2

如果您查看 official docs，您会发现自 API 5 起已弃用此方法，您应该改用 WallpaperManager.setBitmap()。

Answer 3

您可以使用

WallpaperManager.setBitMap()

因为 setWallpaper() 已弃用。

如果您有图片 URI，请使用以下内容：

wallpaperManager = WallpaperManager.getInstance(this);
wallpaperDrawable = wallpaperManager.getDrawable();
mImageView.setImageURI(imagepath)
