像下面这样获取Uri。

//* get cursor like normal

Then

while (cursor.moveToNext()) {
    Uri uri = ContentUris.withAppendedId(
    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id);
}

简单易行。您可以像下面这样从URI执行此操作!

public void getContents(Uri uri)
{
    Cursor vidCursor = getActivity.getContentResolver().query(uri, null, null,
                                                              null, null);
    if (vidCursor.moveToFirst())
    {
        int column_index =
        vidCursor .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        Uri filePathUri = Uri.parse(vidCursor .getString(column_index));
        String video_name =  filePathUri.getLastPathSegment().toString();
        String file_path=filePathUri.getPath();
        Log.i("TAG", video_name + "\b" file_path);
    }
}

由于managedQuery已弃用，您可以尝试:

CursorLoader cursorLoader = new CursorLoader(context, uri, proj, null, null, null);
Cursor cursor = cursorLoader.loadInBackground();

检查下面的方法是工作awesome也奥利奥8.1 ..

@Override

    // TODO ManualMT-generated method stub
    switch (requestCode) {
        case PICKFILE_RESULT_CODE:
            if (resultCode == RESULT_OK) {

                try {
                    FilePath = data.getData().getPath();
                    Uri selectedImageUri = data.getData();

                    if (selectedImageUri.toString().contains("storage/emulated")){
                        String[] split = selectedImageUri.toString().split("storage/");
                        FilePath = "storage/"+split[1];
                    } else {
                        FilePath = ImageFilePath.getPath(getApplicationContext(), selectedImageUri);
                    }

                    recyclerview.setVisibility(View.VISIBLE);

                    if (FilePath == null) {
                        FilePath = "";
                    }
                    File file = new File(FilePath);
                    reqFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
                    image_list.add(FilePath);
                    composeImageAdapter.notifyDataSetChanged();
                } catch (Exception e){
                    Toast.makeText(ClusterCreateNote.this , e.toString(),Toast.LENGTH_SHORT).show();
                }
            }
            break;
    }

只是对第一个答案进行了简单的更新:mActivity.managedQuery()现在已弃用。我已经用新方法更新了代码。

private String getRealPathFromURI(Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    CursorLoader loader = new CursorLoader(mContext, contentUri, proj, null, null, null);
    Cursor cursor = loader.loadInBackground();
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String result = cursor.getString(column_index);
    cursor.close();
    return result;
}

Android开发源码

尝试从Uri获取图像文件路径

public void getImageFilePath(Context context, Uri uri) {

    Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
    cursor.moveToFirst();
    String image_id = cursor.getString(0);
    image_id = image_id.substring(image_id.lastIndexOf(":") + 1);
    cursor.close();
    cursor = context.getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    cursor.moveToFirst();
    String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
    cursor.close();
    upLoadImageOrLogo(path);
}
