关于列表嵌套显示问题

解决办法一：自己写一个方法在设置适配器后调用





public static void setListViewHeightBasedOnChildren(ListView listView) {  

        ListAdapter listAdapter = listView.getAdapter();   

        if (listAdapter == null) {  

            return;  

        }  

        int totalHeight = 0;  

        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);  

    }  

设置完适配器后调用该方法，将ListView作参数传入

Utility.setListViewHeightBasedOnChildren(mListView);

解决办法二：自定义ListView重写onMeasure方法



public class NestListView extends ListView {

    public NestListView(Context context) {

        super(context);

    }

    public NestListView(Context context, AttributeSet attrs) {

        super(context, attrs);

    }

    public NestListView(Context context, AttributeSet attrs, int defStyle) {

        super(context, attrs, defStyle);

    }

    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);

        super.onMeasure(widthMeasureSpec, expandSpec);

    }

}
