RecyclerView的简单使用例子

今天来学习下一个RecyclerView控件
首先先来配置下
<code>
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.0.0-beta1'
compile 'com.android.support:recyclerview-v7:24.+'
}
</code>
接下来做一个横向的例子
xml文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.tony.uiapplication.MainActivity">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        >
    </android.support.v7.widget.RecyclerView>
</RelativeLayout>

java文件

public class MainActivity extends AppCompatActivity {

    private RecyclerView mVRecycler;
    private Adapter mAdapter;
    private List<String> mList;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mVRecycler = (RecyclerView) findViewById(R.id.recyclerview);
        mVRecycler.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
        mList = new ArrayList<>();
        for (int i = 1; i < 17; i++) {
            mList.add("text" + i);
        }
        mAdapter = new Adapter(this, mList);
        mVRecycler.setAdapter(mAdapter);
    }

    class Adapter extends RecyclerView.Adapter<MainActivity.ViewHolder> {

        private Context context;
        private List<String> list;

        public Adapter(Context context, List<String> list) {
            this.context = context;
            this.list = list;
        }

        @Override
        public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            return new ViewHolder(LayoutInflater.from(context).inflate(R.layout.item_recycler, parent, false));
        }

        @Override
        public void onBindViewHolder(ViewHolder holder, int position) {
            holder.vText.setText(list.get(position));
        }

        @Override
        public int getItemCount() {
            return list == null ? 0 : list.size();
        }
    }

    class ViewHolder extends RecyclerView.ViewHolder {
//        ImageView vImage;
        TextView vText;
        public ViewHolder(View itemView) {
            super(itemView);
//            vImage = (ImageView) itemView.findViewById(R.id.img);
            vText = (TextView) itemView.findViewById(R.id.text);
        }
    }
}
