代码段

        View claims = inflater.inflate(R.layout.receipt_text, container, false);
        v=(ImageView)claims.findViewById(R.id.imageView4);
        listV = (ListView) claims.findViewById(R.id.listView1);
        UnderListViewButton=(Button)claims.findViewById(R.id.btnSave); // save button below listView
        FrameLayout footerLayout = (FrameLayout)getActivity().getLayoutInflater().inflate(R.layout.under_listview_button,null);
        UnderListViewButton = (Button) footerLayout.findViewById(R.id.btnSave);
        ViewGroup footer = (ViewGroup) getActivity().getLayoutInflater().inflate(R.layout.total,null);
        listV.addFooterView(footer);
        listV.addFooterView(footerLayout);


   @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
            case 0:
                result = data.getStringExtra("text"); //67
                name = data.getStringExtra("a"); //Project
                description = data.getStringExtra("c");
                as = as + Long.parseLong(result);
                Log.d("FIRST", "result:" + result);
                Text = "  " + name + " " + "RM" + result + "";
                if (mClickedPosition == -1) {
                    m_listItems.add(Text);
                    m_listBitmapItems.add(Global.img);

                } else {
                    m_listItems.set(mClickedPosition, Text);
                    m_listBitmapItems.set(mClickedPosition, Global.img);

                }
                adapter.notifyDataSetChanged();
                listV.setAdapter(adapter);

           }
               long samount=as+bs+cs+ds+es; // total get correctly
               Toast.makeText(getActivity(),samount+"", Toast.LENGTH_LONG).show();
            }

如何显示总计旁边的总金额？

因为total TextView位于footer内，所以请执行以下操作：

1。在类级别而不是在任何方法内部声明footer并在添加到ListView页脚之前对其进行初始化：

...
footer = (AbsoluteLayout) getActivity().
      getLayoutInflater().inflate(R.layout.total,null);
listV.addFooterView(footer);
...

2。在onActivityResult使用findViewById使用footer访问total TextView：

TextView totalTextView = (TextView)footer.findViewById(R.id.tv);
totalTextView.setText("Total :"+ samount);

在listView中显示textView
