Listview在Android中從底部打開

Question

我有一個佈局，我必須在列表視圖頂部和底部添加一些東西，所以我不想只滾動我只想滾動列表視圖我想滾動整個屏幕所以我添加了這個代碼。

//刪除從列表視圖中滾動，使其滾動整個屏幕

public static void setListViewHeightBasedOnChildren(ListView listView) { 
     ListAdapter listAdapter = listView.getAdapter(); 
     if (listAdapter == null) 
      return; 

     int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.UNSPECIFIED); 
     int totalHeight = 0; 
     View view = null; 
     for (int i = 0; i < listAdapter.getCount(); i++) { 
      view = listAdapter.getView(i, view, listView); 
      if (i == 0) 
       view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, ActionBar.LayoutParams.WRAP_CONTENT)); 

      view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED); 
      totalHeight += view.getMeasuredHeight(); 
     } 
     ViewGroup.LayoutParams params = listView.getLayoutParams(); 
     params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); 
     listView.setLayoutParams(params); 
    } 

這裏是我的xml

所以當我打開這個應用程序刪除它從列表視圖中滾動，並添加全在頁面中列出視圖高度，但始終從底部打開。任何解決方案

Answer 1

嘗試使用此設置。

listView.setNestedScrollingEnabled(false); 
listView.setHasFixedSize(false); 

這樣，ListView的滾動將被禁用。
