Question

我正在使用GitHub上提供的google drive api内容来选择文件夹。使用下面的代码，我可以获取文件夹ID来传输数据，但我无法获取文件夹名称或文件夹路径。有人可以帮忙吗？我尝试使用asDriveFolder但没有得到必要的信息。

以下是获取所选文件夹的驱动器ID的代码。

public class GoogleFolderSelector extends GoogleDriveBaseActivity {


    String TAG = "Google Folder Picker";

    private static final int REQUEST_CODE_OPENER = 1;

    @Override
    public void onConnected(Bundle connectionHint) {
        super.onConnected(connectionHint);
        IntentSender intentSender = Drive.DriveApi
                .newOpenFileActivityBuilder()
                .setMimeType(new String[]{DriveFolder.MIME_TYPE})
                .build(getGoogleApiClient());
        try {
            startIntentSenderForResult(
                    intentSender, REQUEST_CODE_OPENER, null, 0, 0, 0);
        } catch (IntentSender.SendIntentException e) {
            Log.w(TAG, "Unable to send intent", e);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        try {
            switch (requestCode) {
                case REQUEST_CODE_OPENER:
                    if (resultCode == RESULT_OK) {
                        DriveId driveId = (DriveId) data.getParcelableExtra(
                                OpenFileActivityBuilder.EXTRA_RESPONSE_DRIVE_ID);
                        DriveFolder driveFolder = driveId.asDriveFolder();

                        showMessage("Folder Path"+ driveFolder);

                        showMessage("Selected folder's ID: " + driveId);

                    }
                    finish();
                    break;
                default:
                    super.onActivityResult(requestCode, resultCode, data);
                    break;
            }
        } catch (Exception e) {
            e.printStackTrace();
            Popup.longpopup("Connection Established, Click to select Folder", this);
        }
    }
}

为了获取文件夹名称，请使用以下元数据

Task<Metadata> getMetadataTask = getDriveResourceClient().getMetadata(file);
getMetadataTask
        .addOnSuccessListener(this,
                metadata -> {
                    showMessage(getString(
                            R.string.metadata_retrieved, metadata.getTitle()));
                    finish();
                })
        .addOnFailureListener(this, e -> {
            Log.e(TAG, "Unable to retrieve metadata", e);
            showMessage(getString(R.string.read_failed));
            finish();
        });

对于文件夹路径，我曾经尝试进行检索，但是似乎没有必要，因为您可以使用driveId进行操作，例如将文件添加到该driveId文件夹中或在该driveId文件夹中创建另一个文件夹。探索google sample app将带给您更好的视野。
