我已经能够设置Google Drive文件选择器,以便我可以读取用户选择的任何文件的内容。但是,我希望能够将用户选择的Google Docs文件下载为文本文件,然后阅读其内容,但我只能使用Drive Rest API找到解决方案,我相信它与适用于Android的Google Drive API。有没有任何解决方案可以让我这样做?目前,我的下载文件代码如下:
final private class RetrieveDriveFileContentsAsyncTask
extends ApiClientAsyncTask<DriveId, Boolean, String> {
public RetrieveDriveFileContentsAsyncTask(Context context) {
super(context);
}
@Override
protected String doInBackgroundConnected(DriveId... params) throws IOException {
String contents = null;
DriveId driveId=params[0];
DriveFile file = driveId.asDriveFile();
DriveApi.DriveContentsResult driveContentsResult =
file.open(getGoogleApiClient(), DriveFile.MODE_READ_ONLY, null).await();
if (!driveContentsResult.getStatus().isSuccess()) {
return null;
}
DriveContents driveContents = driveContentsResult.getDriveContents();
BufferedReader reader = new BufferedReader(new InputStreamReader(driveContents.getInputStream()));
StringBuilder builder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
builder.append('\n');
}
contents = builder.toString();
driveContents.discard(getGoogleApiClient());
return contents;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (result == null) {
return;
}
Intent intent=new Intent(getContext(),NotesActivity.class);
intent.putExtra("setTextTo",result);
startActivity(intent);
}
}

没有Google Drive Android API无法提供转换功能。您需要使用REST API。
