gridHolder.gridAttachmentItem=item.get(position);
try {

} catch (Throwable throwable) {
throwable.printStackTrace();

gridHolder.imgAttachment.setImageBitmap(bitmap);
}
}catch (Exception e){
e.printStackTrace();

}
@Override

return item.size();

public class ViewHolder extends RecyclerView.ViewHolder {

public static Bitmap retriveVideoFrameFromVideo(String videoPath)
throws Throwable {

个联系人，其中包含姓名和电话号码。我需要按姓名过滤该联系人。其过滤名称，但不包括各自的编号。我正在使用此链接执行此任务https://www.journaldev.com/14126/ios-uisearchcontroller-uitableview
但是它具有
之类的模型UITableView我正在从服务器获取models = [
Model(name:"The Dark Night", number:"Action"),
Model(name:"The Avengers", number:"Action"),
Model(name:"Logan", number:"Action"),
Model(name:"Shutter Island", number:"Thriller"),
Model(name:"Inception", number:"Thriller"),
Model(name:"Titanic", number:"Romance"),
Model(name:"La la Land", number:"Romance"),
Model(name:"Gone with the number", genre:"Romance"),
Model(name:"Godfather", number:"Drama"),
Model(name:"Moonlight", number:"Drama")
]
和nameArr。我不能像名称：“ Moonlight”，数字：“ Drama”那样拆分。如何传递数组而不是像这样手动定义？
