以列表形式获取Android中所有捕获的视频 [英] Get all captured Videos in Android as a list

问题描述

我正在尝试使用以下代码在画廊中提供所有视频，

I am trying to get all video available in gallery with below code,

 String[] proj = { MediaStore.Video.Media._ID,MediaStore.Video.Media.DATA,MediaStore.Video.Media.DISPLAY_NAME,MediaStore.Video.Media.SIZE };
 videocursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,proj, null,null, null);
int count = videocursor.getCount();

但是我总是得到count = 0，我在哪里弄错了?

But I always get count = 0, where was I made mistake ?

我也尝试过

Cursor videocursor = managedQuery(MediaStore.Video.Media.INTERNAL_CONTENT_URI, proj, null, null, null);

推荐答案

这样做--

Do like this -

String[] proj = { MediaStore.Video.Media.DATA,
                MediaStore.Video.Media._ID, MediaStore.Video.Media.TITLE,
                MediaStore.Video.Media.DISPLAY_NAME,
                MediaStore.Video.Media.MIME_TYPE,
                MediaStore.Video.Media.DURATION,
                MediaStore.Video.Media.SIZE,};

 String orderBy = android.provider.MediaStore.Video.Media.TITLE;

 Cursor videocursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
               proj, null, null, orderBy);

要获取尺寸，可以使用

 int count = videocursor.getCount();

EDIT managedQuery()已弃用
