java - 如何修复无法降低 ContextWrapper 继承方法的可见性错误？

Question

“private void setWallpaper(Bitmap bitmap)”行给了我一个 Cannot lower the Visibility of the returned method from ContextWrapper 错误，我不知道如何修复它。所以你能帮我吗，谢谢。

这是我的代码:

Thread t = new Thread(new Runnable(){
           public void run(){
               final Bitmap  bmWallpaper = loadImage(toPhone2);
               runOnUiThread(new Runnable(){
               public void run() {
                  setWallpaper(bmWallpaper);    
               }
            });}}
        );
        t.start();
        break;
            }
        }

        private Bitmap loadImage(int id) {
            InputStream WP = getResources().openRawResource(id);
            Bitmap wallpaper = BitmapFactory.decodeStream(WP);
            DisplayMetrics metrics = new DisplayMetrics(); 
            getWindowManager().getDefaultDisplay().getMetrics(metrics);
            int height = metrics.heightPixels; 
            int width = metrics.widthPixels;
            Bitmap tempbitMap = BitmapFactory.decodeResource(getResources(), toPhone2);
            Bitmap bitmap = Bitmap.createScaledBitmap(tempbitMap,width,height, true);
            return bitmap;
        }

        private void setWallpaper(Bitmap bitmap) {
               try{
                    wallpaperManager.setBitmap(bitmap);
                    getApplicationContext().setWallpaper(wallpaper);
                }catch(IOException e){
                    e.printStackTrace();
                }
        }

您重写了函数但更改了范围。只有让它更加明显，而不是更少，才能做到这一点。修复函数的范围，它将编译。
