Answer 1

尝试

private String getRealPathFromURI(String contentURI) {
            Uri contentUri = Uri.parse(contentURI);
            Cursor cursor = mContext.getContentResolver().query(contentUri, null, null, null, null);
            if (cursor == null) {
                return contentUri.getPath();
            } else {
                cursor.moveToFirst();
                int index = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
                String str = cursor.getString(index);
                cursor.close();
                return str;
            }

        }

        String filePath = "";
        String wholeID = DocumentsContract.getDocumentId(uri);

        // Split at colon, use second item in the array
        String id = wholeID.split(":")[1];
        String[] column = {MediaStore.Images.Media.DATA};

        // where id is equal to
        String sel = MediaStore.Images.Media._ID + "=?";
        Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, column, sel, new String[]{id}, null);
        int columnIndex = cursor.getColumnIndex(column[0]);

Answer 2

public static String getFilePathByUri(Context context, Uri uri) {

    String fileName = "";
    Uri filePathUri = uri;

    if (uri.getScheme().toString().compareTo("content") == 0) {

        Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);

        if (cursor.moveToFirst()) {
            int column_index = cursor.getColumnIndexOrThrow("_data");
            filePathUri = Uri.parse(cursor.getString(column_index));
            fileName = filePathUri.getEncodedPath();
        }

        cursor.close();

    } else if (uri.getScheme().compareTo("file") == 0) {
        fileName = filePathUri.getEncodedPath();
    } else {
        fileName = fileName + "_" + filePathUri.getLastPathSegment();
    }
    return fileName;
}
