單擊搜索按鈕時，Android listview滾動到底部

Question

我已經實現了帶搜索功能的listview。搜索按鈕在操作欄中，使用下面的代碼，一切正常。

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.top_right, menu); 
    MenuItem searchItem = menu.findItem(R.id.search); 
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem); 
    //*** setOnQueryTextFocusChangeListener *** 
    searchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() { 
     @Override 
     public void onFocusChange(View v, boolean hasFocus) { 

     } 
    }); 

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() { 
     @Override 
     public boolean onQueryTextSubmit(String query) { 

      return false; 
     } 

     @Override 
     public boolean onQueryTextChange(String searchQuery) { 
       myAppAdapter.filter(searchQuery.toString().trim()); 
       listView.invalidate(); 
      return true; 
     } 
    }); 

    MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() { 
     @Override 
     public boolean onMenuItemActionCollapse(MenuItem item) { 
      // Do something when collapsed 
      return true; // Return true to collapse action view 
     } 

     @Override 
     public boolean onMenuItemActionExpand(MenuItem item) { 
      // Do something when expanded 
      return true; // Return true to expand action view 
     } 
    }); 
    return true; 
} 

這裏是我的XML：

<ListView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:layout_centerHorizontal="true" 
    android:layout_below="@+id/appBar" 
    android:choiceMode="multipleChoice" 
    android:id="@+id/list1" 
    android:layout_above="@+id/txtTotal" /> 

我的搜索功能工作正常，但問題是當有人點擊搜索按鈕，整個列表視圖滾動至底部。我將如何解決這個問題？ 在此先感謝！

注意：我已經搜索了這種問題的stackoverflow，但我沒有找到任何。如果有任何問題，請與我分享鏈接。

編輯：有關我的適配器的其他信息。正如評論部分所述。

 public class MyAppAdapter extends BaseAdapter { 
    public class ViewHolder { 
     TextView txtName; 
     CheckBox chkItem; 
    } 

    public List<ClassOrder> parkingList; 

    public Context context; 
    ArrayList<ClassOrder> arraylist; 

    private MyAppAdapter(List<ClassOrder> apps, Context context) { 
     this.parkingList = apps; 
     this.context = context; 
     arraylist = new ArrayList<ClassOrder>(); 
     arraylist.addAll(parkingList); 
    } 

    @Override 
    public int getCount() { 
     return parkingList.size(); 
    } 

    @Override 
    public Object getItem(int position) { 
     return position; 
    } 

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

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 

     View rowView = convertView; 
     /*ViewHolder viewHolder;*/ 

     if (rowView == null) { 
      LayoutInflater inflater = getLayoutInflater(); 
      rowView = inflater.inflate(R.layout.list_xml, null); 
      // configure view holder 
      viewHolder = new ViewHolder(); 
      viewHolder.chkItem = (CheckBox) rowView.findViewById(R.id.chkItem); 
      rowView.setTag(viewHolder); 
     } else { 
      viewHolder = (ViewHolder) convertView.getTag(); 
     } 

     viewHolder.txtName.setText(parkingList.get(position).getItemDetail() + ""); 
     viewHolder.chkItem.setFocusable(false); 
     viewHolder.chkItem.setChecked(positionArray.get(position)); 

     return rowView; 
    } 
} 

我list_xml：

<RelativeLayout 
    android:layout_width="match_parent" 
    android:id="@+id/ac" 
    android:padding="10dp" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/txtSub" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentStart="true"> 

    <ImageView 
     android:layout_width="40dp" 
     android:layout_height="40dp" 
     app:srcCompat="@mipmap/ic_launcher" 
     android:id="@+id/imageView2" 
     android:layout_marginRight="5dp" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentStart="true" /> 

    <TextView 
     android:text="menu name" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:id="@+id/txtName" 
     android:textSize="14sp" 
     android:textStyle="bold" 
     android:textColor="@color/colorPrimary" 
     android:gravity="center|left" 
     android:layout_alignParentTop="true" 
     android:layout_toRightOf="@+id/imageView2" 
     android:layout_toEndOf="@+id/imageView2" 
     android:layout_alignBottom="@+id/imageView2" /> 

    <CheckBox 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:button="@null" 
     android:drawableRight="?android:attr/listChoiceIndicatorMultiple" 
     android:buttonTint="@color/colorPrimary" 
     android:focusable="false" 
     android:focusableInTouchMode="false" 
     android:gravity="right|center" 
     android:id="@+id/chkItem" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentEnd="true" 
     android:layout_alignBottom="@+id/txtName" 
     android:layout_toRightOf="@+id/txtName" 
     android:layout_toEndOf="@+id/txtName" /> 

</RelativeLayout>

其實我是無意中把下面一行在搜索菜單按鈕的的OnClick。這是導致ListView向下滾動。

listView.smoothScrollToPosition(myAppAdapter.getCount()); 

很抱歉，我搜索了我的所有錯誤代碼，但不是onClick事件。謝謝大家和Stackoverflowians誰花了時間來解決這個問題。我很抱歉！
