我尝试使用进度条修改下载示例中的koush代码,使其写入FileOutputStream而不是File,但是eclipse会给我以下错误:
方法progressHandler(new ProgressCallback(){})未定义 类型ResponseFuture
以下是代码:
File file = new File(DownloadPath, uri.getLastPathSegment());
FileOutputStream fos = null;
try {
fos = new FileOutputStream(file);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
}
Future<FileOutputStream> downloading = Ion.with(getApplicationContext())
.load(uri)
.write(fos)
.progressHandler(new ProgressCallback() {
@Override
public void onProgress(int downloaded, int total) {
// inform the progress bar of updates in progress
}
})
.setCallback(new FutureCallback<FileOutputStream>() {
@Override
public void onCompleted(Exception e, FileOutputStream file) {
// download done...
// do stuff with the File or error
}
});
答案 0 :(得分:7)
你好像搞砸了订单。请试试这个:
Future<FileOutputStream> downloading = Ion.with(getApplicationContext())
.load("http://example.com/test.txt")
.progressHandler(new ProgressCallback() {
@Override
public void onProgress(int downloaded, int total) {
// inform the progress bar of updates in progress
}
})
.write(fos)
.setCallback(new FutureCallback<FileOutputStream>() {
@Override
public void onCompleted(Exception e, FileOutputStream file) {
// download done...
// do stuff with the File or error
}
});
