ScroolView 和 ListView 显示冲突问题。

以下有两种方案：

1. 手动计算ListView每个Item的高度。然后设置ListView的高度。

public static void setListViewHeight(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);  
    }  

 

2.重写ListView的OnMeasure方法，计算每个Item的高度

public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) 
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
                MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }
