ListView多布局Adapter封装

出现需求

多布局的话使用RecyclerView更为合理，但是目前项目使用的是eclipse，普遍使用的是ListView，若为一个界面而引入RecyclerView不划算不合理。所以将Adapter简单修改后让ListView具备多布局能力。

分装Adapter

public abstract class AbsListAdapter<T> extends BaseAdapter {    protected Context mContextInAbsAdapter;    List<T> mDataList;    public AbsListAdapter(Context mContext) {        super();        this.mContextInAbsAdapter = mContext;        this.mDataList = new ArrayList<T>();    }    public void setData(@NonNull List<T> tempDatas) {        this.mDataList.clear();        this.addDatas(tempDatas);    }    public void addDatas(@NonNull List<T> tempDatas) {        this.mDataList.addAll(tempDatas);        this.notifyDataSetChanged();    }    public void addData(@NonNull T data) {        this.mDataList.add(data);        this.notifyDataSetChanged();    }    public void addData(int index, @NonNull T data) {        this.mDataList.add(index, data);        this.notifyDataSetChanged();    }    public void removeData(int index){        if (index != ParamUtil.checkInt(index, 0, this.mDataList.size())) {            return ;        }        this.mDataList.remove(index);        this.notifyDataSetChanged();    }    public void removeData(T t){        if (t == null) {            return;        }        int index = this.mDataList.indexOf(t);        removeData(index);    }    public void clearData() {        this.mDataList.clear();        this.notifyDataSetChanged();    }    public List<T> getDatas() {        return new ArrayList<T>(this.mDataList);    }    @Nullable    public T getData(int index) {        if (index != ParamUtil.checkInt(index, 0, this.mDataList.size())) {            return null;        }        return this.mDataList.get(index);    }    @SuppressLint("ViewTag") @Override    public View getView(int position, View convertView, ViewGroup parent) {        T data = null;        // getCount() 可能被覆写        if (position < this.mDataList.size()) {            data = this.mDataList.get(position);        }        int itemLayoutResId = getItemLayoutResId(position, data);        if (convertView != null && (Integer) convertView.getTag() != itemLayoutResId) {            convertView.setTag(((Integer) convertView.getTag()), null);            convertView = null;        }        ViewHolder holder = null;        if (convertView != null) {            holder = (ViewHolder) convertView.getTag(itemLayoutResId);        }        if (holder == null) {            convertView = LayoutInflater.from(mContextInAbsAdapter).inflate(itemLayoutResId, parent, false);            holder = new ViewHolder(convertView);            convertView.setTag(itemLayoutResId);            convertView.setTag(itemLayoutResId, holder);        }        onBindData(position, data, holder);        return convertView;    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public int getCount() {        return mDataList.size();    }    @Override    public Object getItem(int position) {        return null;    }    public abstract int getItemLayoutResId(int position, T data);    public abstract void onBindData(int position, T data, ViewHolder holder);    public static class ViewHolder {        private SparseArray<View> viewCache;        private View itemView;        public ViewHolder(View containerView) {            this.itemView = containerView;            this.viewCache = new SparseArray<View>();        }        @SuppressWarnings("unchecked")        public <T extends View> T getView(int resId) {            View view = this.viewCache.get(resId);            if (view == null) {                view = this.itemView.findViewById(resId);                this.viewCache.put(resId, view);            }            return (T) view;        }        public View getConvertView() {            return this.itemView;        }        public void setText(int resId, CharSequence text) {            TextView textView = this.getView(resId);            textView.setText(text);        }    }}

使用例子

private class MyAdapter extends AbsListMultiAdapter<String>{        public MyAdapter(Context mContext) {            super(mContext);        }        @Override        public int getItemLayoutResId(int position, String data) {            // 可以根据position或data判断            return position % 2 == 0 ? R.layout.item_voice_assistant : R.layout.v_textview;        }        @Override        public void onBindData(int position, String data, com.elife.mobile.base.AbsListAdapter3.ViewHolder holder) {            // TODO Auto-generated method stub            holder.setText(R.id.tv_textView, data);        }    }
