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。

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) {

}
});
}
}

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));
}
}

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();
}
}

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;
}

/**
