android - 如何获取要在android中下载的谷歌驱动器文件的url

Question

我可以从谷歌驱动器中获取文件的驱动器 ID。通过以下代码。

import com.example.googledrivetest2.ProcessDownload.DownloadFileAsync;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.PendingResult;
import com.google.android.gms.common.api.Result;
import com.google.android.gms.common.api.ResultCallback;
import com.google.android.gms.drive.Drive;
import com.google.android.gms.drive.DriveApi;
import com.google.android.gms.drive.DriveApi.DriveContentsResult;
import com.google.android.gms.drive.DriveApi.DriveIdResult;
import com.google.android.gms.drive.DriveContents;
import com.google.android.gms.drive.DriveFile;
import com.google.android.gms.drive.DriveFolder;
import com.google.android.gms.drive.DriveFolder.DriveFileResult;
import com.google.android.gms.drive.DriveId;
import com.google.android.gms.drive.DriveResource;
import com.google.android.gms.drive.Metadata;
import com.google.android.gms.drive.MetadataChangeSet;
import com.google.android.gms.drive.OpenFileActivityBuilder;

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        Log.i(TAG, "in onActivityResult() - triggered on pressing Select");

        switch (requestCode) {

            case REQUEST_CODE_SELECT:
                if (resultCode == RESULT_OK) {
                    /*get the selected item's ID*/
                    DriveId driveId = (DriveId) data.getParcelableExtra(
                            OpenFileActivityBuilder.EXTRA_RESPONSE_DRIVE_ID);//this extra contains the drive id of the selected file
                    Log.i(TAG, "Selected folder's ID: " + driveId.encodeToString());
                    Log.i(TAG, "Selected folder's Resource ID: " + driveId.getResourceId());// this is the id of the actual file
                    Toast.makeText(getApplicationContext()," my id: "+driveId.getResourceId() , Toast.LENGTH_LONG).show();

                    DriveFile file = Drive.DriveApi.getFile(googleApiClient,driveId);
                   ....
                     }
                };

现在我想获取该文件的 URL，以便我可以使用此 LINK 传递 URL 进行下载

你试过这个方法了吗？

DriveFile file = Drive.DriveApi.getFile(googleApiClient,driveId);
MetadataResult mdRslt = file.getMetadata(googleApiClient).await();
if (mdRslt != null && mdRslt.getStatus().isSuccess()) {
   String link = mdRslt.getMetadata().getWebContentLink();
   Log.d("LINK", link);
}
