查询到 MediaStore.Video.Media.EXTERNAL_CONTENT_URI 返回唯一的视频/ SD卡/ DCIM / 100MEDIA

不过，我想缩略图的视频在我的 / SD卡/安卓/数据/ mypackage中/文件文件夹。这可能吗？

下面是我的code部分：

  ContentResolver的CR = getContentResolver（）;
    的String [] PROJ = {
                    BaseColumns._ID
    };

    光标C = cr.query（MediaStore.Video.Media.EXTERNAL_CONTENT_URI，凸出，NULL，NULL，NULL）;
    如果（c.moveToFirst（））{
        做
        {
            INT的id = c.getInt（0）;
            位图B = MediaStore.Video.Thumbnails.getThumbnail（CR，ID，MediaStore.Video.Thumbnails.MINI_KIND，NULL）;
            Log.d（*****我的缩略图*****，位图的onCreate+ b）的;
            ImageView的IV =（ImageView的）findViewById（R.id.img_thumbnail）;
            iv.setImageBitmap（B）;
        }
        而（c.moveToNext（））;
    }
    c.close（）;
 

解决方案

如果你是在Android-8（升级Froyo）或以上，你可以使用ThumbnailUtils.createVideoThumbnail:

 位图拇指= ThumbnailUtils.createVideoThumbnail（路径，
    MediaStore.Images.Thumbnails.MINI_KIND）;
 

Query to MediaStore.Video.Media.EXTERNAL_CONTENT_URI returns only video in /sdcard/DCIM/100MEDIA

But I want to get thumbnails for video in my /sdcard/Android/data/mypackage/files folder. Is it possible ?

Here is part of my code:

        ContentResolver cr = getContentResolver();
    String[] proj = {
                    BaseColumns._ID
    };

    Cursor c = cr.query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, proj, null, null, null);
    if (c.moveToFirst()) {
        do
        {
            int id = c.getInt(0);
            Bitmap b = MediaStore.Video.Thumbnails.getThumbnail(cr, id, MediaStore.Video.Thumbnails.MINI_KIND, null);
            Log.d("*****My Thumbnail*****", "onCreate bitmap " + b);
            ImageView iv = (ImageView) findViewById(R.id.img_thumbnail);
            iv.setImageBitmap(b);
        }
        while( c.moveToNext() );
    }         
    c.close();

If you are on android-8 (Froyo) or above, you can use ThumbnailUtils.createVideoThumbnail:

Bitmap thumb = ThumbnailUtils.createVideoThumbnail(path,
    MediaStore.Images.Thumbnails.MINI_KIND);
