我正在开发一个Android应用,它应该能够从谷歌驱动器中读取电子表格。但是,每当我尝试从谷歌驱动器打开文件时,我都会收到来自DriveContentsResult的消息:"此文件没有可用的内容"。
这是我的代码,在我通过GoogleApiClient获得谷歌驱动器的授权后:
private static final int REQUEST_RESOLVE_ERROR = 1001;
public static final int REQUEST_CODE_OPENER = 1002;
private DriveId mSelectedFileDriveId;
public GoogleApiClient mGoogleApiClient;
public void getGoogleDriveFile(View view){
if(mGoogleApiClient.isConnected()){
IntentSender intentSender = Drive.DriveApi
.newOpenFileActivityBuilder()
.setMimeType(new String[] {"application/vnd.google-apps.spreadsheet"})
.build(mGoogleApiClient);
try {
startIntentSenderForResult(intentSender, REQUEST_CODE_OPENER, null, 0, 0, 0);
} catch (SendIntentException e) {
Log.d(TAG, "Unable to send intent" + e);
}
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG, "onActivityResult");
if (requestCode == REQUEST_RESOLVE_ERROR) {
...
} else if(requestCode == REQUEST_CODE_OPENER){
if(resultCode == RESULT_OK){
mSelectedFileDriveId = (DriveId) data.getParcelableExtra(OpenFileActivityBuilder.EXTRA_RESPONSE_DRIVE_ID);
if(mSelectedFileDriveId != null){
open();
}
}
}
}
private void open() {
Drive.DriveApi.getFile(mGoogleApiClient, mSelectedFileDriveId)
.open(mGoogleApiClient, DriveFile.MODE_READ_ONLY, null)
.setResultCallback(driveContentsCallback);
}
private ResultCallback<DriveContentsResult> driveContentsCallback =
new ResultCallback<DriveContentsResult>() {
@Override
public void onResult(DriveContentsResult result) {
if (!result.getStatus().isSuccess()) {
Log.d(TAG, "Error while opening the file contents " + result.getStatus().getStatusMessage());
return;
}
DriveContents contents = result.getDriveContents();
}
};

此处的内容是指二进制内容。 Google Spreadsheets(以及其他Google Docs类型)不会存储为二进制内容。特定于Android的API目前不支持阅读电子表格内容。
使用RESTful API,您可以使用ExportLinks以二进制格式(如csv)获取它。

使用&#34; google电子表格api&#34; (REST)没有驱动api。
