listview添加headview后的点击事件

1、头部view：设置view的点击时间，用于屏蔽listview的item的点击事件

<span style="white-space:pre">		</span>View headerView = getLayoutInflater().inflate(R.layout.listhead, null);
		Button btn = (Button) headerView.findViewById(R.id.button1);
		btn.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View arg0) {
				Toast.makeText(MainActivity.this, "bn", Toast.LENGTH_SHORT)
						.show();
			}
		});

2、添加头部view：必须放在setAdapter前面不然会报错

		lv.addHeaderView(headerView);

3、listview填充假数据

		List<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
		HashMap<String, String> map = new HashMap<String, String>();
		map.put("tv", "tv");
		list.add(map);
		list.add(map);
		list.add(map);
		list.add(map);
		list.add(map);
		list.add(map);

<span style="white-space:pre">		</span>SimpleAdapter sa = new SimpleAdapter(this, list, R.layout.item_lv,
<span style="white-space:pre">				</span>new String[] { "tv" }, new int[] { R.id.tv });

4、设置适配器：如果listview不设置适配器，headview也不会显示的

<span style="white-space:pre">		</span>lv.setAdapter(sa);

5、设置item点击事件

		lv.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1,
					int position, long id) {
				
				//position 如果有headview  position =0 的第一个为headview
				Toast.makeText(MainActivity.this, "position:" + position,
						Toast.LENGTH_SHORT).show();
				
				//id：如果有headview或者footview  则这两个view的id为-1
				if (id == -1) {
					Toast.makeText(MainActivity.this, "head:" + id,
							Toast.LENGTH_SHORT).show();
				} else {
					Toast.makeText(MainActivity.this, "id:" + id,
							Toast.LENGTH_SHORT).show();
				}

			}
		});
