使用

1.简单的 CygAdapter

mAdapter = new CygAdapter<Student>(getContext(), android.R.layout.simple_list_item_1, datas) {
    @Override
    public void onBindData(CygViewHolder viewHolder, Student item, int position) {
        TextView tv = viewHolder.findViewById(android.R.id.text1);
        tv.setText(item.naem + "：" + item.age + "岁");
        if (position == getCurrentCheckPosition()) {
            tv.setBackgroundColor(Color.RED);
        } else {
            tv.setBackgroundColor(Color.WHITE);
        }
    }
};
setListAdapter(mAdapter);

2.多视图 CygMultiViewTypeAdapter

内部已定义SparseIntArray变量，用于存储视图数据<k,v> = <viewType,layoutId>
构造函数中CygMultiViewTypeAdapter(Context context, List objects, SparseIntArray itemViewTypes)传入视图数据SparseIntArray
也可以用提供的addItemViewType(viewType,layoutId)方法来装入视图数据<viewType,layoutId>
主要是getItemViewType方法，根据情况返回相应的viewType，用法与BaseAdapter getItemViewType(int position)一样

public class ChatAdapter extends CygMultiViewTypeAdapter<ChatMsg> {
    private static final int VIEW_TYPE_TO_TEXT = 0;
    private static final int VIEW_TYPE_FROM_TEXT = 1;
    private static final int VIEW_TYPE_TO_IMAGE = 2;
    private static final int VIEW_TYPE_FROM_IMAGE = 3;

    public ChatAdapter(Context context, List objects) {
        super(context, objects, null);
        addItemViewType(VIEW_TYPE_TO_TEXT, R.layout.fragment_multi_view_type_to_item_text);
        addItemViewType(VIEW_TYPE_FROM_TEXT, R.layout.fragment_multi_view_type_from_item_text);
        addItemViewType(VIEW_TYPE_TO_IMAGE, R.layout.fragment_multi_view_type_to_item_image);
        addItemViewType(VIEW_TYPE_FROM_IMAGE, R.layout.fragment_multi_view_type_from_item_image);
    }

    @Override
    public int getItemViewType(ChatMsg item, int position) {
        if (item.isTo) {
            if (item.msgType == ChatMsg.MsgType.TEXT) return VIEW_TYPE_TO_TEXT;
            else return VIEW_TYPE_TO_IMAGE;
        } else {
            if (item.msgType == ChatMsg.MsgType.TEXT) return VIEW_TYPE_FROM_TEXT;
            else return VIEW_TYPE_FROM_IMAGE;
        }
    }

    @Override
    public void onBindData(CygViewHolder viewHolder, ChatMsg item, int position, int viewType) {
        if (viewType == VIEW_TYPE_FROM_TEXT || viewType == VIEW_TYPE_TO_TEXT) {
            viewHolder.setText(R.id.textView, item.msgContent);
        } else if (viewType == VIEW_TYPE_FROM_IMAGE || viewType == VIEW_TYPE_TO_IMAGE) {
            ImageView imageView = viewHolder.findViewById(R.id.imageView1);
            imageView.setImageResource(item.msgImage);
        }
    }
}

3.带`CompoundButton`视图的 CygCheckedAdapter

内部已解决滑动错乱的问题，只需要在构造方法传入CompoundButton的id

mAdapter = new CygCheckedAdapter<String>(getContext(),
        R.layout.fragment_checked_changed_item,R.id.checkBox, datas) {

    @Override
    public void onBindData(CygViewHolder viewHolder, String item, final int position) {
        viewHolder.setText(android.R.id.text1, item);
    }
};
setListAdapter(mAdapter);

那么在ListView的单击事件中如何改变CompoundButton的状态呢？好办提供了toggleCheckObject(view, position)方法

@Override
public void onListItemClick(ListView listView, View view, int position, long id) {
    mAdapter.toggleCheckObject(view, position);
}

更多方法

    /**
     * 切换 CompoundButton 状态<br>
     * 例如：AdapterView.OnItemClickListener 中调用
     *
     * @param view
     * @param position
     */
    public final void toggleCheckObject(View view, int position) {
        CygViewHolder viewHolder = (CygViewHolder) view.getTag();
        CompoundButton compoundButton = viewHolder.findViewById(mCheckViewId);
        compoundButton.toggle();
        toggleCheckObject(compoundButton.isChecked(), position);
    }

    /**
     * 切换 CompoundButton 状态<br>
     * 例如：AdapterView.OnItemClickListener 中，已知 CompoundButton 的状态<br>
     * 只有当选择模式已被设置为 CHOICE_MODE_SINGLE 或 CHOICE_MODE_MULTIPLE 时, isItemChecked 结果才有效<br>
     * boolean isChecked = listView.isItemChecked(position);
     *
     * @param isChecked
     * @param position
     */
    public final void toggleCheckObject(boolean isChecked, int position) {
        if (isChecked)
            putCheckObject(position);
        else
            removeCheckObject(position);
    }

    /**
     * 删除选中数据
     */
    public final void removeCheckObjects() {
        int size = getCheckSize();
        for (int i = 0; i < size; i++) {
            remove(mSparseObjects.valueAt(i));
        }
        clearCheckObjects();
    }

    /**
     * 取得选中数据大小
     *
     * @return
     */
    public final int getCheckSize() {
        return mSparseObjects.size();
    }

    /**
     * 取出选中数据
     *
     * @return
     */
    public final List<T> getCheckObjects() {
        List<T> list = new ArrayList<>();
        for (int i = 0; i < mSparseObjects.size(); i++) {
            list.add(mSparseObjects.valueAt(i));
        }
        return list;
    }
