ListView添加header

1.headerView布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >
<LinearLayout
    android:visibility="gone"
    android:orientation="vertical"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
......
 </LinearLayout>
</RelativeLayout>

2.获取headerView的布局

inflate = LayoutInflater.from(getApplicationContext()).inflate(R.layout.view_header, null);

3.在setAdapter前，添加headerView

listView.getRefreshableView().addHeaderView(inflate);

4.隐藏headerView布局
注意：根布局设置为GONE是无效的

container = inflate.findViewById(R.id.container);
container.setVisibility(View.GONE);

知识小补充

一直显示至底部，聊天专用：
listView.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
