android – 使用毕加索从url保存图像？

概述我正在尝试使用API​​毕加索保存图像.要做到这一点,我正在尝试使用Target来保存,但我无法做到这一点. 我该怎么做？ 试 //save image public static void imageDownload(Context ctx){ Picasso.with(ctx) .load("http://blog.concretesol 我正在尝试使用API​​毕加索保存图像.要做到这一点,我正在尝试使用Target来保存,但我无法做到这一点.

我该怎么做？

试

//save image    public static voID imageDownload(Context ctx){        Picasso.with(ctx)                .load("http://blog.concretesolutions.com.br/wp-content/uploads/2015/04/AndroID1.png")                .into(getTarget("http://blog.concretesolutions.com.br/wp-content/uploads/2015/04/AndroID1.png"));    }    //target to save    private static Target getTarget(final String url){        Target target = new Target(){            @OverrIDe            public voID onBitmapLoaded(final Bitmap bitmap,Picasso.LoadedFrom from) {                new Thread(new Runnable() {                    @OverrIDe                    public voID run() {                        //Log.i("PRODUTOS_FolDER",CreateAppFolder.getProdutosFolder());                        file file = new file(Environment.getExternalStorageDirectory() + url);                        try {                            file.createNewfile();                            fileOutputStream ostream = new fileOutputStream(file);                            bitmap.compress(Bitmap.CompressFormat.JPEG,100,ostream);                            ostream.flush();                            ostream.close();                        }                        catch (Exception e) {                            e.printstacktrace();                        }                    }                }).start();            }            @OverrIDe            public voID onBitmapFailed(Drawable errorDrawable) {            }            @OverrIDe            public voID onPrepareLoad(Drawable placeHolderDrawable) {            }        };        return target;    }

例外

java.io.IOException: open Failed: ENOENT (No such file or directory)

解决方法 解决了.现在工作正常！

我做了

//save image    public static voID imageDownload(Context ctx,String url){        Picasso.with(ctx)                .load("http://blog.concretesolutions.com.br/wp-content/uploads/2015/04/AndroID1.png")                .into(getTarget(url));    }    //target to save    private static Target getTarget(final String url){        Target target = new Target(){            @OverrIDe            public voID onBitmapLoaded(final Bitmap bitmap,Picasso.LoadedFrom from) {                new Thread(new Runnable() {                    @OverrIDe                    public voID run() {                        file file = new file(Environment.getExternalStorageDirectory().getPath() + "/" + url);                        try {                            file.createNewfile();                            fileOutputStream ostream = new fileOutputStream(file);                            bitmap.compress(Bitmap.CompressFormat.JPEG,80,ostream);                            ostream.flush();                            ostream.close();                        } catch (IOException e) {                            Log.e("IOException",e.getLocalizedMessage());                        }                    }                }).start();            }            @OverrIDe            public voID onBitmapFailed(Drawable errorDrawable) {            }            @OverrIDe            public voID onPrepareLoad(Drawable placeHolderDrawable) {            }        };        return target;    }
