RecyclerView的Adapter的抽取

RecyclerView的Adapter的抽取

最近常用recyclerview控件，每次都需要写一大串代码，于是参考了鸿洋的文章，抽取了一个adapter的基类。

具体代码：

ContentFragment类

public class ContentFragment extends Fragment {    private RecyclerView mRecyclerView;    private SwipeRefreshLayout mSwipeRefreshLayout;    private List<Bean> mLists = new ArrayList<>();    private CommomAdapter adapter;    private View view;    private LinearLayoutManager manager;    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {        return inflater.inflate(R.layout.fragment_content, container, false);    }    @Override    public void onViewCreated(View view, Bundle savedInstanceState) {        mRecyclerView = (RecyclerView) view.findViewById(R.id.recycler);        mSwipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.refresh);        this.view = LayoutInflater.from(getContext()).inflate(R.layout.footer_view, null, false);        initRefresh();        initRecycler();        initData();        initListener();    }    private void initRefresh() {        mSwipeRefreshLayout.setColorSchemeResources(android.R.color.holo_red_dark, android.R.color.holo_orange_dark, android.R.color.holo_green_dark, android.R.color.holo_blue_bright);        mSwipeRefreshLayout.setOnRefreshListener(new OnRefreshListener() {            @Override            public void onRefresh() {                mSwipeRefreshLayout.postDelayed(new Runnable() {                    @Override                    public void run() {                        mSwipeRefreshLayout.setRefreshing(false);                    }                }, 2000);            }        });    }    private void initRecycler() {        manager = new LinearLayoutManager(getContext());        mRecyclerView.setLayoutManager(manager);        mRecyclerView.setHasFixedSize(true);        adapter = new ContentAdapter(getContext(), R.layout.fragment_content_recycer_item, mLists);        mRecyclerView.setAdapter(adapter);    }    private void initData() {        Bean bean = new Bean("窗前明月有几许");        for (int i = 0; i < 30; i++) {            try {                mLists.add(bean.clone());            } catch (CloneNotSupportedException e) {                e.printStackTrace();            }        }    }    private void initListener() {        mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {            @Override            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {            }            @Override            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {            }        });    }}

ContentAdapter

public class ContentAdapter extends CommonAdapter<Bean> {    public ContentAdapter(Context context, @LayoutRes int layoutRes, @NonNull List<Bean> list) {        super(context, layoutRes, list);    }    @Override    protected void convert(MyViewHolder holder, Bean bean) {        holder.setText(R.id.tv_content, bean.getName()).setTextColor(R.id.tv_content, mContext.getResources().getColor(android.R.color.holo_orange_dark));    }}

CommonAdapter

public abstract class CommonAdapter<T> extends RecyclerView.Adapter<MyViewHolder> {    protected Context mContext;    protected List<T> mLists;    private int mLayoutRes;    public CommonAdapter(Context context, @LayoutRes int layoutRes, @NonNull List<T> list) {        this.mContext = context;        this.mLayoutRes = layoutRes;        this.mLists = list;    }    @Override    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        return MyViewHolder.get(mContext, mLayoutRes, parent);    }    @Override    public void onBindViewHolder(MyViewHolder holder, int position) {        convert(holder, mLists.get(position));    }    protected abstract void convert(MyViewHolder holder, T t);    @Override    public int getItemCount() {        if (mLists == null) {            return 0;        }        return mLists.size();    }}

MyViewHolder

public class MyViewHolder extends RecyclerView.ViewHolder {    private SparseArray<View> mViews;    private Context mContext;    public MyViewHolder(View itemView) {        super(itemView);        mViews = new SparseArray<>();    }    public MyViewHolder(View itemView, Context context) {        this(itemView);        mContext = context;    }    public static MyViewHolder get(Context context, @LayoutRes int layoutRes, ViewGroup parent) {        View view = LayoutInflater.from(context).inflate(layoutRes, parent, false);        return new MyViewHolder(view, context);    }    public <T extends View> T getView(@IdRes int viewId) {        View view = mViews.get(viewId);        if (view == null) {            view = itemView.findViewById(viewId);            mViews.put(viewId, view);        }        return (T) view;    }    public View getItemView() {        return itemView;    }    /**     * @by zhang 2016/6/10 ------------------------监听事件-----------------------------------     */    /**     * @by zhang 2016/6/10 条目的点击事件     */    public MyViewHolder setOnItemclickListener(View.OnClickListener listener) {        itemView.setOnClickListener(listener);        return this;    }    /**     * @by zhang 2016/6/10  条目的触摸事件     */    public MyViewHolder setOnTouchListener(View.OnTouchListener listener) {        itemView.setOnTouchListener(listener);        return this;    }    /** @by zhang 2016/6/10 可以继续拓展------------------------------------------- */    /**     * @by zhang 2016/6/10 -------------------给itemView中的控件设置属性-----------------------     */    /**     * @by zhang 2016/6/10 给定TextView的id,设置text     */    public MyViewHolder setText(@IdRes int viewId, String text) {        TextView view = getView(viewId);        view.setText(text);        return this;    }    public MyViewHolder setTextColor(@IdRes int viewId, @ColorInt int color) {        TextView view = getView(viewId);        view.setTextColor(color);        return this;    }    /** @by zhang 2016/6/10 可以继续拓展------------------------------------------- */}
