ListView添加headview
1、头部view:设置view的点击时间,用于屏蔽listview的item的点击事件
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> list = new ArrayList>(); HashMap map = new HashMap(); map.put(tv, tv); list.add(map); list.add(map); list.add(map); list.add(map); list.add(map); list.add(map);
SimpleAdapter sa = new SimpleAdapter(this, list, R.layout.item_lv,
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
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(); } } });
main.java全部代码:
import java.util.ArrayList; import java.util.HashMap; import java.util.List; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.Button; import android.widget.ListView; import android.widget.SimpleAdapter; import android.widget.Toast; public class MainActivity extends Activity { ListView lv; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); lv = (ListView) findViewById(R.id.listView1); // 头部view:设置view的点击时间,用于屏蔽listview的item的点击事件 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(); } }); // 添加头部view:必须放在adapter前面不然会报错 lv.addHeaderView(headerView); // 假数据 List> list = new ArrayList>(); HashMap map = new HashMap(); map.put(tv, tv); list.add(map); list.add(map); list.add(map); list.add(map); list.add(map); list.add(map); SimpleAdapter sa = new SimpleAdapter(this, list, R.layout.item_lv, new String[] { tv }, new int[] { R.id.tv }); // 设置适配器:如果listview不设置适配器,headview也不会显示的 lv.setAdapter(sa); // 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(); } } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } }
