毕加索库不从的Adroid SD卡载入图像 [英] Picasso library does not load images from SD card on adroid

问题描述

我需要从图片库路径的文件，并尝试按以下步骤加载一个图像视图。文件路径是：/storage/sdcard0/DCIM/Camera/1436267579864.jpg。我也试过路过乌里我也看过权限到SD卡上。

它结束了在的onError（）方法。然而类似的方法工作正常的网页的URL。我该如何解决此问题？

 私人无效的getImage（档案文件）{

        如果（file.exists（））{

            Picasso.with（活动）
                    .load（文件）
                    .error（R.drawable.noimage）
                    。走进（IMG preVIEW，新的回调（）{
                        @覆盖
                        公共无效的onSuccess（）{
                            如果（进度= NULL和放大器;！＆安培;！IMG preVIEW = NULL）{

                                IMG preview.setVisibility（View.VISIBLE）;
                                IMG preview.setTag（装）;
                                progressBar.setVisibility（View.GONE）;

                            }
                        }

                        @覆盖
                        公共无效onerror的（）{
                            如果（进度= NULL和放大器;！＆安培;！IMG preVIEW = NULL）{
                                IMG preview.setVisibility（View.VISIBLE）;
                                progressBar.setVisibility（View.GONE）;
                            }
                        }

                    }）;
   }

解决方案

虽然为时已晚，但我还是坚持到同样的问题，所以我解决了下面的方法。仅仅使用和追加的文件：//在路径的开始。看看这样的：

  Picasso.with（上下文）//
                    .load（文件：//+ myFilePath）//
                    .error（R.mipmap.error）
                    .placeholder（R.mipmap.ic_launcher）
                    。适合（）
                    .TAG（MyActivity.this）//
                    。走进（ImageView的，新的ImageLoadedCallback（进度）{
                        @覆盖
                        公共无效的onSuccess（）{
                            progressBar.setVisibility（View.GONE）;
                        }

                        @覆盖
                        公共无效onerror的（）{
                            Log.d（毕加索错误，错误）;

                        }
                    }）;
 

这解决了我的问题。只是回答，这样如果有一个人摔倒在同样的问题，来这里的解决方案，那么他可能会得到他的问题，通过这个解决。

I take a file from path from image gallery and try to load it a image view as follows. File path is: /storage/sdcard0/DCIM/Camera/1436267579864.jpg. I also tried passing Uri I also have read privileges to SD card.

It ends up in onError() method. However similar method works fine for web urls. How can I resolve this?

private void getImage(File file) {

        if(file.exists()) {

            Picasso.with(activity)
                    .load(file)
                    .error(R.drawable.noimage)
                    .into(imgPreview, new Callback() {
                        @Override
                        public void onSuccess() {
                            if (progressBar != null && imgPreview != null) {

                                imgPreview.setVisibility(View.VISIBLE);
                                imgPreview.setTag("loaded");
                                progressBar.setVisibility(View.GONE);

                            }
                        }

                        @Override
                        public void onError() {
                            if (progressBar != null && imgPreview != null) {
                                imgPreview.setVisibility(View.VISIBLE);
                                progressBar.setVisibility(View.GONE);
                            }
                        }

                    });
   }

解决方案

Though it is too late , but I stuck into same problem, so I solved in the following way . Just using and appending "file://" in the starting of path. take a look at this:

 Picasso.with(context) //
                    .load("file://" +myFilePath) //
                    .error(R.mipmap.error)
                    .placeholder(R.mipmap.ic_launcher)
                    .fit()
                    .tag(MyActivity.this) //
                    .into(imageView, new ImageLoadedCallback(progressBar) {
                        @Override
                        public void onSuccess() {
                            progressBar.setVisibility(View.GONE);
                        }

                        @Override
                        public void onError() {
                            Log.d("Picasso Error", "Error");

                        }
                    });

This solves my problem . Just answering so that if some one fall in the same problem and came here for solution then he may get his problem solved through this.
