上传进度监听器没有被解雇（谷歌驱动API） [英] Upload progress listener not fired (Google drive API)
本文介绍了上传进度监听器没有被解雇（谷歌驱动API）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想用谷歌驱动的API来显示通过上传文件的百分比进度。
我menthod已经成功上载前的文件，但它无法看到上传进度。
我已经看到了，并添加<一href="http://stackoverflow.com/questions/13580109/check-progress-for-upload-download-google-drive-api-for-android-or-java">this FileUploadProgressListener 但 mediaHttpUploader.getProgress（）只显示0.0（进度开始）和1.0（时进度完成）。我不能让进步％的时间。
如何使它工作？
下面是我上传code：
公共无效UploadFile（最终DFile uploadFile）{
如果（！isLoggedIn（））{
OnUploadGoogleChecked（FALSE，未登录）;
返回;
}
AsyncTask的＆LT;虚空龙，串＆GT;任务=新的AsyncTask＆LT;虚空龙，串＆GT;（）{
的java.io.File fileContent;
FileContent mediaContent;
com.google.api.services.drive.model.File体;
com.google.api.services.drive.model.File文件;
私人ProgressDialog mDialog;
长mFileLen;
@覆盖
在preExecute保护无效（）{
// TODO自动生成方法存根
super.on preExecute（）;
mDialog =新ProgressDialog（行为）;
mDialog.setMax（100）;
mDialog.setMessage（上传）;
mDialog.setProgressStyle（ProgressDialog.STYLE_HORIZONTAL）;
mDialog.setProgress（0）;
mDialog.setButton（取消，新OnClickListener（）{
@覆盖
公共无效的onClick（DialogInterface为arg0，INT ARG1）{
// TODO自动生成方法存根
}
}）;
mDialog.show（）;
}
类FileUploadProgressListener实现MediaHttpUploaderProgressListener {
@覆盖
公共无效progressChanged（MediaHttpUploader上传）抛出IOException异常{
Log.d（海豚得到百分比，将String.valueOf（uploader.getProgress（）））;
开关（uploader.getUploadState（））{
案例INITIATION_STARTED：
的System.out.println（初始启动）;
打破;
案例INITIATION_COMPLETE：
的System.out.println（启动完成）;
打破;
案例MEDIA_IN_PROGRESS：
的System.out.println（正在上传）;
的System.out.println（上传百分比：+ uploader.getProgress（））;
打破;
案例MEDIA_COMPLETE：
的System.out.println（上传完成！）;
打破;
案例NOT_STARTED：
的System.out.println（上传未启动！）;
打破;
}
}
}
@覆盖
保护字符串doInBackground（虚空......为arg0）{
尝试 {
java.io.File的UPLOAD_FILE =新的java.io.File（uploadFile.getNameAndDir（））;
//文件的元数据。
fileContent =新的java.io.File（uploadFile.getNameAndDir（））;
mFileLen = fileContent.length（）;
InputStreamContent mediaContent2 =新InputStreamContent（图像/ JPEG，新的BufferedInputStream（新的FileInputStream（UPLOAD_FILE）））;
mediaContent2.setLength（UPLOAD_FILE.length（））;
身体=新com.google.api.services.drive.model.File（）;
body.setTitle（fileContent.getName（））;
body.setMimeType（为image / jpeg）;
字符串parentId的= NULL;
body.setParents（Arrays.asList（新ParentReference（）SETID（uploadFile.getFileHostFolderId（））））;
。Drive.Files.Insert MINSERT = service.files（）插入（身体，mediaContent2）;
MediaHttpUploader上传= mInsert.getMediaHttpUploader（）;
uploader.setDirectUploadEnabled（真正的）;
uploader.setProgressListener（新FileUploadProgressListener（））;
文件= mInsert.execute（）;
如果（文件！= NULL）{
}
}赶上（UserRecoverableAuthIOException E）{
Log.d（海豚出现错误，无法登录+ E）;
}赶上（IOException异常E）{
e.printStackTrace（）;
}
返回null;
}
保护无效onPostExecute（字符串结果）{
mDialog.dismiss（）;
OnUploadGoogleChecked（TRUE，上传完成）;
};
};
task.execute（）;
}
解决方案
要取得进步，必须使用 uploader.setDirectUploadEnabled（假）; ，而不是（真）和 uploader.setChunkSize（MediaHttpUploader.MINIMUM_CHUNK_SIZE）; 或必须
I want to show progress by percent of an uploading file using Google drive API.
My menthod has successful upload a file before but It can't see upload progress.
I've seen and added this FileUploadProgressListener but mediaHttpUploader.getProgress() show only 0.0 (start of progress) and 1.0 (when progress finished). I can't get percent of progress in time.
How to make It work?
Here is my Upload code:
public void UploadFile(final DFile uploadFile) {
if (!isLoggedIn()) {
OnUploadGoogleChecked(FALSE, "Not logged in");
return;
}
AsyncTask<Void, Long, String> task = new AsyncTask<Void, Long, String>() {
java.io.File fileContent;
FileContent mediaContent;
com.google.api.services.drive.model.File body;
com.google.api.services.drive.model.File file;
private ProgressDialog mDialog;
long mFileLen;
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
mDialog = new ProgressDialog(act);
mDialog.setMax(100);
mDialog.setMessage("Uploading ");
mDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mDialog.setProgress(0);
mDialog.setButton("Cancel", new OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub
}
});
mDialog.show();
}
class FileUploadProgressListener implements MediaHttpUploaderProgressListener {
@Override
public void progressChanged(MediaHttpUploader uploader) throws IOException {
Log.d("Dolphin got percent", String.valueOf(uploader.getProgress()));
switch (uploader.getUploadState()) {
case INITIATION_STARTED:
System.out.println("Initiation Started");
break;
case INITIATION_COMPLETE:
System.out.println("Initiation Completed");
break;
case MEDIA_IN_PROGRESS:
System.out.println("Upload in progress");
System.out.println("Upload percentage: " + uploader.getProgress());
break;
case MEDIA_COMPLETE:
System.out.println("Upload Completed!");
break;
case NOT_STARTED:
System.out.println("Upload Not Started!");
break;
}
}
}
@Override
protected String doInBackground(Void... arg0) {
try {
java.io.File UPLOAD_FILE = new java.io.File(uploadFile.getNameAndDir());
// File's metadata.
fileContent = new java.io.File(uploadFile.getNameAndDir());
mFileLen = fileContent.length();
InputStreamContent mediaContent2 = new InputStreamContent("image/jpeg", new BufferedInputStream(new FileInputStream(UPLOAD_FILE)));
mediaContent2.setLength(UPLOAD_FILE.length());
body = new com.google.api.services.drive.model.File();
body.setTitle(fileContent.getName());
body.setMimeType("image/jpeg");
String parentId = null;
body.setParents(Arrays.asList(new ParentReference().setId(uploadFile.getFileHostFolderId())));
Drive.Files.Insert mInsert = service.files().insert(body, mediaContent2);
MediaHttpUploader uploader = mInsert.getMediaHttpUploader();
uploader.setDirectUploadEnabled(true);
uploader.setProgressListener(new FileUploadProgressListener());
file = mInsert.execute();
if (file != null) {
}
} catch (UserRecoverableAuthIOException e) {
Log.d("Dolphin got error", "not login " + e);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String result) {
mDialog.dismiss();
OnUploadGoogleChecked(TRUE, "Upload complete");
};
};
task.execute();
}
解决方案
To get progress, you must use uploader.setDirectUploadEnabled(false); (instead of true) and uploader.setChunkSize(MediaHttpUploader.MINIMUM_CHUNK_SIZE); or any value which must be the multiply of MediaHttpUploader.MINIMUM_CHUNK_SIZE, else it will cause error.
