从File或FilePath获取Uri

Question

我有这条路径的文件：

file:/storage/emulated/0/iWallet/photos/JPEG_20180119040510_972640968.jpg

我想将其转换为android.net.Uri并在此处使用它：

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
        if (photoFile != null) {
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,photoFile.toURI());
            startActivityForResult(takePictureIntent, REQUEST_TAKE_CAMIRA);
        }
    }

Answer 1

试试这个：

Uri.fromFile(new File("/storage/emulated/0/iWallet/photos/JPEG_20180119040510_972640968.jpg"))

Answer 2

我的问题在于文件提供商，所以我解决了这个问题

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {

        if (photoFile != null) {
            Uri photoURI = FileProvider.getUriForFile(context,
                    DBConnect.FILEPROVIDER,
                    photoFile);

            URI uri = photoFile.toURI();


            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,photoURI);
            startActivityForResult(takePictureIntent, REQUEST_TAKE_CAMIRA);
        }
    }
