android scrollview中嵌套expandablelistview

http://blog.csdn.net/swust_chenpeng/article/details/17413955

一、重新expandablelistview

public class CustomExpandableListView extends ExpandableListView {

    public CustomExpandableListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // TODO Auto-generated method stub
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,

        MeasureSpec.AT_MOST);

        super.onMeasure(widthMeasureSpec, expandSpec);
    }
}

二、动态计算expandablelistview的高度，xxx_group.xml和xxx_child.xml的最外层要用linearlayout，反正relativelayout不行，不知道为什么

private void setListViewHeight(ExpandableListView listView) {
        ListAdapter listAdapter = listView.getAdapter();
        int totalHeight = 0;
        int count = listAdapter.getCount();
        for (int i = 0; i < listAdapter.getCount(); i++) {
            View listItem = listAdapter.getView(i, null, listView);
            listItem.measure(0, 0);
            totalHeight += listItem.getMeasuredHeight();
        }

        ViewGroup.LayoutParams params = listView.getLayoutParams();
        params.height = totalHeight
                + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
        listView.setLayoutParams(params);
        listView.requestLayout();
    }

三、scrollveiew中嵌套的listview的话，前两种都行，还有一种如下

public class ViewGroupForListView extends LinearLayout implements View.OnClickListener {

    private ListAdapter mAdapter = null;
    private OnItemClickListener mListener = null;

    public ViewGroupForListView(Context context) {
        super(context);
    }

    public ViewGroupForListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
        this.setOrientation(VERTICAL);
    }

    /**
     * 绑定数据
     */
    protected void bindData() {
        int count = mAdapter.getCount();
        for(int i = 0; i < count; i++) {
            View v = mAdapter.getView(i, null, null);
            v.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            v.setOnClickListener(this);
            v.setId(i);
            addView(v, i);
        }
    }

    /**
     * 设置adapter
     * @param adapter
     */
    public void setAdapter(ListAdapter adapter) {
        mAdapter = adapter;
        if(this.getChildCount() != 0) {
            removeAllViews();
        }
        bindData();
    }

    /**
     * 获取adapter
     * @return
     */
    public ListAdapter getAdapter() {
        return mAdapter;
    }

    /**
     * 绑定监听
     * @param listener
     */
    public void setOnItemClickListener(OnItemClickListener listener) {
        this.mListener = listener;
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        if(mListener != null) {
            mListener.onItemClick(v.getId(), mAdapter);
        }
    }

    /**
     * 监听接口
     * @author Visual
     *
     */
    public interface OnItemClickListener {
        public void onItemClick(int position, ListAdapter adapter);
    }

adapter的实现类似普通listview的adapter用法
