推荐答案
使用google drive Api上传图片文件
upload image files using google drive Api
您可以使用以下代码将图片文件上传到 Google Drive :
You could use the following codes to upload the image file to Google Drive :
DriveClass.DriveApi.NewDriveContents(client).SetResultCallback(new System.Action<IDriveApiDriveContentsResult>((result)=> {
//Create MetadataChangeSet
MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder()
.SetTitle("Test.jpg")
.SetMimeType("image/jpeg").Build();
var contents = result.DriveContents;
//push the bitmap data to DriveContents
bitmapFromYourPicture.Compress(CompressFormat.Jpeg, 1, contents.OutputStream);
IntentSender intentSender = DriveClass.DriveApi
.NewCreateFileActivityBuilder()
.SetInitialMetadata(metadataChangeSet)
.SetInitialDriveContents(contents)
.Build(client);
StartIntentSenderForResult(intentSender, 2, null, 0, 0, 0);
}));
如果您使用意图选择图像图片,您可以获得这样的图片Bitmap
:
If you choose the image picture by using intent you could get the picture Bitmap
like this :
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
if (requestCode == 0)
{
var uri = data.Data;
System.IO.Stream image_stream = ContentResolver.OpenInputStream(uri);
Bitmap getBitmap = BitmapFactory.DecodeStream(image_stream);
}
}
