Question

我有一张带有2个textviews的cardview。第一个textview显示联系人的姓名，第二个显示电话号码。我想使用ArrayList来填充recyclerview。

我还不熟悉Android编程，所以我不知道如何实现RecyclerView或者在textview中创建一个在名称和数字之间交替的适配器。我怎样才能做到这一点？

我的CardView（card_row.xml）

 <?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="5dp"
    android:clickable="true"
    android:orientation="horizontal"
    card_view:cardCornerRadius="0dp"
    card_view:cardUseCompatPadding="true" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="?android:selectableItemBackground"
    android:orientation="vertical">

    <TextView
        android:id="@+id/text1"
        android:layout_width="match_parent"
        android:layout_height="38dp"
        android:layout_margin="5dp"
        android:gravity="left"
        android:textColor="@android:color/black"
        android:textSize="24sp" />
    <TextView
        android:id="@+id/text2"
        android:layout_width="match_parent"
        android:layout_height="37dp"
        android:layout_margin="5dp"
        android:layout_below="@id/text1"
        android:textColor="@android:color/darker_gray"
        android:textSize="18sp" />
</LinearLayout>

</android.support.v7.widget.CardView>

编辑：我制作了2个arraylists，一个用于名字，另一个用于数字。现在我如何填充recyclerview？

OK首先做一个内部课。这将是您的适配器更改所有id：

class Adapter extends RecyclerView.Adapter<LibraryAdapter.MyViewHolder>{
    LayoutInflater inflater;

    public LibraryAdapter(Context context){
        inflater = LayoutInflater.from(context);
    }


    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view =inflater.inflate(R.layout.main_exerciselibrary_fragment_singlerow,parent,false);
        MyViewHolder holder=new MyViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        Exercises exercises = new Exercises(getActivity());
            ArrayList<String> arrayList1 = new ArrayList<String>();
            ArrayList<String> arrayList2 = new ArrayList<String>();

            holder.Name.setText(arrayList1.get(position));
            holder.PhoneNumber.setText(arrayList2.get(position));



    }

    @Override
    public int getItemCount() {

        return array.lenght;
    }

    class MyViewHolder extends RecyclerView.ViewHolder{

        TextView Name, PhoneNumber;
        CardView card;

        public MyViewHolder(View itemView) {
            super(itemView);

            PhoneNumber= (TextView) itemView.findViewById(R.id.imageViewPicLibrary);//change Here
            Name = (TextView) itemView.findViewById(R.id.textViewExerciseLibraryExerciseName);//change Here
            card= (CardView) itemView.findViewById(R.id.card_view_ex_lib);//change Here

            card.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    //OnClick
                }
            });


        }


    }
}

我认为这就是全部。

使用ArrayList填充RecyclerView和CardView <string>
