如何在安卓程序中通过图片链接编程设置壁纸？

Question

我正在尝试通过图像链接设置壁纸。

我的问题是：如何显示对话框“从服务器加载图像”，然后是“设置壁纸”。此后，弹出窗口会询问用户他们想在哪里设置壁纸。

当前情况：当用户点击“设置壁纸”按钮时，它仅显示对话框消息并继续加载。然后用户需要关闭弹出窗口并再次点击。这意味着他们需要点击两次才能设置壁纸。我希望让他们更容易理解。

基本上，我希望我的用户知道在安卓中运行了哪些进程。

以下是代码：

progressDialog = ProgressDialog.show(getActivity(),"Please wait...","Set as your wallpaper...",false,true);
               

                Picasso.get()
                        .load(setImgLink)
                        .into(new Target() {
                            @Override
                            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                                WallpaperManager wallpaperManager = WallpaperManager.getInstance(getActivity());

                                try {
                                    if (bitmap != null) {
                                        wallpaperManager.setBitmap(bitmap);
                                        Snackbar.make(relative_image_slider, "Wallpaper was set", Snackbar.LENGTH_SHORT).show();
                                        progressDialog.dismiss();
                                        ct_popup.setText("Wallpaper was set");
                                        final AlertDialog.Builder builder1 = new AlertDialog.Builder(getActivity());
                                        builder1.setView(subView);
                                        builder1.setPositiveButton("Close", new DialogInterface.OnClickListener() {
                                            @Override
                                            public void onClick(DialogInterface dialog, int which) {
                                                dialog.cancel();
                                                ((ViewGroup)subView.getParent()).removeView(subView);
                                            }
                                        });
                                        builder1.setIcon(R.mipmap.ic_launcher);
                                        builder1.setCancelable(false);
                                        builder1.create();
                                        builder1.show();
                                    }else {
                                        Toast.makeText(getActivity(), "Unable to set your wallpaper !!", Toast.LENGTH_LONG).show();
                                    }


                                } catch (IOException e) {
                                    Toast.makeText(getActivity(), "Something went wrong !!", Toast.LENGTH_LONG).show();
                                    e.printStackTrace();
                                }
                            }

                            @Override
                            public void onBitmapFailed(Exception e, Drawable errorDrawable) {

                            }

                            @Override
                            public void onPrepareLoad(Drawable placeHolderDrawable) {

                            }
                        });

使用Glide

               Glide.with(context)
                .asBitmap().load(imageurl)
                .listener(object : RequestListener<Bitmap> {
                    override fun onLoadFailed(
                            e: GlideException?,
                            model: Any?,
                            target: com.bumptech.glide.request.target.Target<Bitmap>?,
                            isFirstResource: Boolean
                    ): Boolean {
                        return false
                    }

                    override fun onResourceReady(
                            resource: Bitmap?,
                            model: Any?,
                            target: com.bumptech.glide.request.target.Target<Bitmap>?,
                            dataSource: DataSource?,
                            isFirstResource: Boolean
                    ): Boolean {

                        val wallpaperManager = WallpaperManager.getInstance(context)
                        try {
                            resource?.let {
                                wallpaperManager.setBitmap(it)
                            }

                        } catch (e: Exception) {
                            e.printStackTrace()
                        }

                        return false
                    }
                }).submit()

谢谢@axar的回答，但是答案与我的问题无关。 - Rohit Kumar Sehrawat

Answer 3

你是否在某些情况下多次初始化了 progressDialog？如果是，请只初始化一次并在需要时进行编辑。

ProgressDialog progressDialog = new ProgressDialog(this); // Initialize once
progressDialog.setTitle("Please wait...");// can edit
progressDialog.setMessage("Set as your wallpaper...");// can edit
progressDialog.setCancelable(true);// can edit
progressDialog.setIndeterminate(false);// can edit
progressDialog.show();
progressDialog.dismiss();

- Loop

谢谢@ashik，但我的问题是如何使用Glide在Android中设置壁纸。目前我使用的是Picasso，但它存在一些困难。 - Rohit Kumar Sehrawat
