推荐答案
最后，我发现我的解决方案，现在我能够将图像从相机（它可以在驱动器快速启动）和第二部分，我已经做了选择从画廊的照片，并将其存储到谷歌驱动器为好。请参阅下面
At Last I have found my solution and now I am able to send images to Google Drive from camera (Which is available on Drive Quick Start) and second part I have done that select a picture from Gallery and store it to Google Drive as well. See Code below
@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data)
{
switch (requestCode)
{
case REQUEST_ACCOUNT_PICKER:
if (resultCode == RESULT_OK && data != null && data.getExtras() != null)
{
String accountName = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
if (accountName != null)
{
credential.setSelectedAccountName(accountName);
service = getDriveService(credential);
}
}
break;
case REQUEST_AUTHORIZATION:
if (resultCode == Activity.RESULT_OK)
{
saveFileToDrive();
}
else
{
startActivityForResult(credential.newChooseAccountIntent(), REQUEST_ACCOUNT_PICKER);
}
break;
case SELECT_PICTURE:
if (resultCode == Activity.RESULT_OK)
{
selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
tvPath.setText("File Path: " + selectedImagePath);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
break;
case CAPTURE_IMAGE:
if (resultCode == Activity.RESULT_OK)
{
/*String mediaStorageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES).getPath();
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US).format(new Date());
selectedImageUri = Uri.fromFile(new java.io.File(mediaStorageDir + java.io.File.separator + "IMG_"
+ timeStamp + ".jpg"));*/
selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
img.setImageURI(selectedImageUri);
}
break;
}
}
/*************** This method leads you to start your device's camera *****************/
private void startCameraIntent()
{
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, selectedImageUri);
startActivityForResult(cameraIntent, CAPTURE_IMAGE);
}
/*************** This method will take you to gallery *****************/
private void selectPictureIntent()
{
Intent pictureintent = new Intent();
pictureintent.setType("image/jpeg");
pictureintent.setAction(Intent.ACTION_GET_CONTENT);
pictureintent.putExtra(MediaStore.EXTRA_OUTPUT, selectedImageUri);
startActivityForResult(pictureintent, SELECT_PICTURE);
}
private void saveFileToDrive()
{
Thread t = new Thread(new Runnable()
{
@Override
public void run()
{
try
{
// File's binary content
java.io.File fileContent = new java.io.File(selectedImagePath);// here I was wrong I was sending selectedImageUri.getPath(); and now I am getting path by making getPath() Method and get Path where the image is saved in phone.
FileContent mediaContent = new FileContent("image/jpeg", fileContent);
// File's metadata.
File body = new File();
body.setTitle(fileContent.getName());
body.setMimeType("image/jpeg");
File file = service.files().insert(body, mediaContent).execute();
if (file != null)
{
pd.dismiss();
}
else
{
pd.dismiss();
System.out.println("File not sent...");
}
}
catch (UserRecoverableAuthIOException e)
{
startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
}
catch (IOException e)
{
e.printStackTrace();
}
}
});
t.start();
}
public String getPath(Uri uri)
{
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImageUri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
