次のコードを使用して、MultipartEntityBuilder を使用してサーバーに写真をアップロードしています。最後のどこかにそれは言い// FIXME Put your progress bar stuff here!ます。関数全体を Asynctask に入れるべきか、ファイルのアップロード中に進行状況を表示するために何をすべきかわかりません。
MultipartEntityBuilder を使用して、進行状況バーを使用して HTTP フォームからファイルをアップロードすることを確認しましたが、実際には役に立ちません。
public String postFile(String fileName) throws Exception {
fileName = "/mnt/sdcard/DCIM/100MEDIA/IMAG0309.jpg";
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://www.mywebsite.com/upload_file.php");
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
final File file = new File(fileName);
FileBody fb = new FileBody(file);
builder.addPart("file",fb);
String userid = session_userid;
builder.addTextBody("userID", userid);
final HttpEntity yourEntity = builder.build();
class ProgressiveEntity implements HttpEntity {
@Override
public void consumeContent() throws IOException {
yourEntity.consumeContent();
}
@Override
public InputStream getContent() throws IOException,

}
yourEntity.writeTo(new ProgressiveOutputStream(outstream));
}
};
ProgressiveEntity myEntity = new ProgressiveEntity();
post.setEntity(myEntity);
HttpResponse response = client.execute(post);
return getContent(response);
}
これが私がやったことですが、それを完了するにはまだ皆さんが必要です:
