Question

我在标题和按钮之间有一个列表视图，我想在listview和按钮上方添加textview以正确对齐，以便按钮不会覆盖listview项目。我怎样才能做到这一点？不确定xml布局的问题是什么

layout.xml

您是否考虑过向listview添加标题视图。您实际上可以使用布局作为listview的标题。这样，您对标题的查看将永远不会溢出到列表视图。

final ListView lstVRHDetails = (ListView) getActivity().findViewById(R.id.listview);

        LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View headerView = inflater.inflate(<header layout>, new LinearLayout(getActivity()), false);

        headerView.findViewById(R.id.rlFromDate).setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {

            }
        });
        headerView.findViewById(R.id.rlToDate).setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {

            }
        });

        headerView.findViewById(R.id.imgUpdate).setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

            }
        });

        headerView.setLayoutParams(new ListView.LayoutParams(ListView.LayoutParams.MATCH_PARENT, ListView.LayoutParams.WRAP_CONTENT));
        lstVRHDetails.addHeaderView(headerView);
