如何在佈局中添加完整的滾動視圖？

Question

在下面的代碼中如何滾動不只是ListView，但所有的視圖與它？如果我正在添加完整頁面scrollview，則listview不顯示完整頁面。

但頂層菜單應該是不變的。搜索按鈕內部我想滾動完整列表。

您應該複製的佈局，要與不同的佈局XML列表視圖滾動並把它放到列表視圖的頂部，一個不同的第一個項目。您可以使用自定義ListAdapter做到這一點：

//WARNING: I did not try this code, handle it like pseudocode 
private class MyCustomAdapter extends BaseAdapter { 

    private ArrayList<Item> mData = new ArrayList<>(); 
    private LayoutInflater mInflater; 

    public MyCustomAdapter() { 
     mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 

    public void addItem(final Item item) { 
     mData.add(item); 
     notifyDataSetChanged(); 
    } 

    @Override 
    public int getCount() { 
     return mData.size() + 1; 
    } 

    @Override 
    public Item getItem(int position) { 
     return mData.get(position); 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     ViewHolder holder = null; 
     if(position==0){ 
      //initialize your custom view 
     }else{ 
      //initialize a normal list item 
     } 
     return convertView; 
    } 
} 

檢查this ListAdapter例如，如果您還有問題！

使用此功能可以在滾動視圖上查看完整列表。

ListView listViewObject; 

// after binding list view. 
getListViewSize(listViewObject);// pass your listview object here. 


public void getListViewSize(ListView myListView) { 
    ListAdapter myListAdapter = myListView.getAdapter(); 
    if (myListAdapter == null) { 
     //do nothing return null 
     return; 
    } 
    //set listAdapter in loop for getting final size 
    int totalHeight = 0; 
    for (int size = 0; size < myListAdapter.getCount(); size++) { 
     View listItem = myListAdapter.getView(size, null, myListView); 
     listItem.measure(0, 0); 
     totalHeight += listItem.getMeasuredHeight(); 
    } 
    //setting listview item in adapter 
    ViewGroup.LayoutParams params = myListView.getLayoutParams(); 
    params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1)); 
    myListView.setLayoutParams(params); 
    // print height of adapter on log 
    Log.i("height of listItem:", String.valueOf(totalHeight)); 
} 

希望！它對你有幫助......
