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

    }
}
}

`我正在使用 API 23，应用程序的最低 API 是 16。那么我应该怎么做才能修复错误

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，您应该使用 WallpaperManager.setBitMap()相反。
