从相册或者文件夹获取视频文件的路径！

Intent in = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(in, REQUEST_CALENDAR);

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if(data == null ){

return;

}

if (requestCode == REQUEST_CALENDAR) {

String path=Uri.decode(data.getDataString());

Uri uri = Uri.parse(path);

path = Tool.getPathFromUri(mactivity, uri);

AppLog.d("dingdong", "path========="+path);

}else if(requestCode == REQUEST_FILE){

String path=Uri.decode(data.getDataString());

if(!MediaFile.isVideoFileType(path)){

Uri uri = Uri.parse(path);

path = Tool.getPathFromUri(mactivity, uri);

}

if(path!=null&&!"".equals(path)){

if(path.startsWith("file://")){

int position = path.indexOf("/")+2;

AppLog.d("dingdong", "position === "+position);

path = path.substring(position);

}

}
