Question

我想在android中实现文件选择器。我已经实现了以下代码来打开文件选择器。

public static void showFileChooser(Activity activity, Fragment fragment) {
        try {

            File imageStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "example");
            if (!imageStorageDir.exists()) {
                imageStorageDir.mkdirs();
            }
            File file = new File(imageStorageDir + File.separator + "IMG_" + String.valueOf(System.currentTimeMillis()) + ".jpg");
            mCapturedImageURI = Uri.fromFile(file); // save to the private variable

            final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
            captureIntent.putExtra("capturedimageuri", mCapturedImageURI.toString());

            // Intent for Audio Recording
            final Intent audioRecordIntent = new Intent();
            audioRecordIntent.setAction(IAdoddleConstants.ACTION_AUDIO_RECORD);

            final Intent videoRecordIntent = new Intent();
            videoRecordIntent.setAction(IAdoddleConstants.ACTION_VIDEO_RECORD);

            // Use the GET_CONTENT intent from the utility class
            Intent target = com.asite.adoddle.filechooser.FileUtils.createGetContentIntent();
            // Create the chooser Intent


            if (activity != null) {
                Intent intent = Intent.createChooser(
                        target, activity.getString(R.string.chooser_title));

                intent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { captureIntent,audioRecordIntent, videoRecordIntent});
                activity.startActivityForResult(intent, IMAGE_ANNOTATION_REQUEST_CODE);
            } else {
                Intent intent = Intent.createChooser(
                        target, fragment.getString(R.string.chooser_title));

                intent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { captureIntent,audioRecordIntent, videoRecordIntent});
                fragment.startActivityForResult(intent, IMAGE_ANNOTATION_REQUEST_CODE);
            }

        } catch (ActivityNotFoundException e) {
            AdoddleLog.e(DEBUG_TAG, "Error:" + e);
        } catch (Exception ex) {
            ex.printStackTrace();
            CommonUtilities.showToast(activity, activity.getString(R.string.error_message), Toast.LENGTH_LONG);
        }
    }

现在它打开filechooser，如下所示。

现在，当我点击“文档”时，我会从不同的应用程序中选择相同的文件，如下所示。

在这里，您可以看到Google云端硬盘和Dropbox等应用。现在我想从这个应用程序中选择文件。现在，当我从dropbox中选择文件，然后在onActivityResult(int requestCode, int resultCode, Intent data)中，我从意图中得到内容：//com.dropbox.android.FileCache/filecache/2642b6eb-f9da-4775-b6c5-6cb4d6884018 uri。现在如何从这个uri获得真正的路径？我想在我的活动中附上这个文件。此外，我无法获得谷歌驱动器文件的真实路径。

要使用图像或视频真实路径：

protected String getPhotoUriRealPath(Uri contentURI) {
    String path = "";
    if (contentURI == null) {
        return path;
    }
    Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);

    if (cursor == null) {
        path = contentURI.getPath();
    } else {
        cursor.moveToFirst();
        int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
        path = cursor.getString(idx);

    }
    if (cursor != null) {
        cursor.close();
    }
    return path;
}

protected String getVideoUriRealPath(Uri contentURI) {
    String path = "";
    if (contentURI == null) {
        return path;
    }
    Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);

    if (cursor == null) {
        path = contentURI.getPath();
    } else {
        cursor.moveToFirst();
        int idx = cursor.getColumnIndex(MediaStore.Video.VideoColumns.DATA);
        path = cursor.getString(idx);

    }
    if (cursor != null) {
        cursor.close();
    }
    return path;
}

如何从android filechooser dropbox和谷歌驱动器中获取来自给定uri的真实路径？
