问题描述
我正在尝试使用API Picasso保存图像.为此,我正在尝试使用Target
保存,但是我无法完成这项工作.
I'm trying save an image using API Picasso. To do it I'm trying use Target
to save but I can't do this work.
我该怎么做?
尝试
//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)

Solved. now works fine!
我做到了
//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;
}
