这几天关于这个ListView一团乱。现在重新梳理下：
①项vlist.xml:
②页面activity_list.xml:
③ListViewActivity.xml:
package cn.com.smartcost.offer.ui;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import cn.com.smartcost.offer.R;
import android.app.Activity;
import android.os.Bundle;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.SimpleAdapter;
public class ListViewActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
//绑定Layout里面的ListView
ListView list = (ListView) findViewById(R.id.ListView01);
//生成动态数组，加入数据
List> listItem = new ArrayList>();
for(int i=0;i<10;i++)
{
HashMap map = new HashMap();
map.put(materialName, Level +i);
map.put(materialFormat, Finished in 1 Min 54 Secs, 70 Moves! );
listItem.add(map);
}
//生成适配器的Item和动态数组对应的元素
SimpleAdapter listItemAdapter = new SimpleAdapter(this,listItem,//数据源
R.layout.vlist,//ListItem的XML实现
//动态数组与ImageItem对应的子项
new String[] {materialName, materialFormat},
//ImageItem的XML文件里面的一个ImageView,两个TextView ID
new int[] {R.id.materialName,R.id.materialFormat}
);
//添加并且显示
list.setAdapter(listItemAdapter);
//添加点击
list.setOnItemClickListener(new OnItemClickListener() {
@SuppressWarnings(unchecked)
@Override
public void onItemClick(AdapterView parent, View view, int position,
long id) {
ListView lView = (ListView)parent;
Map map = (Map) lView.getItemAtPosition(position);
setTitle(点击第+map.get(materialName).toString()+个项目);
}
});
}
//长按菜单响应函数
@Override
public boolean onContextItemSelected(MenuItem item) {
setTitle(点击了长按菜单里面的第+item.getItemId()+个项目);
return super.onContextItemSelected(item);
}
}
