ListView控件：（2）SimpleAdapter适配器生成

1.java代码

package com.yun.activity;
 
import java.util.ArrayList;
import java.util.HashMap;
 
import com.example.yunsheng.R;
 
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;
 
public class MySimpleAdapter extends Activity {
 
  @Override
  protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_simpleadapter);
 
  ListView lv = (ListView) findViewById(R.id.lv);
  /* 定义一个动态数组 */
  ArrayList<HashMap<String, Object>> listItem = new ArrayList<HashMap<String, Object>>();
  /* 在数组中存放数据 */
  for (int i = 0; i < 10; i++) {
    HashMap<String, Object> map = new HashMap<String, Object>();
 
    map.put("userId", "第" + i + "行");
    map.put("userName", "这是第" + i + "行");
    map.put("userImage", R.drawable.ic_ipod);// 加入图片
    listItem.add(map);
  }
 
  SimpleAdapter mSimpleAdapter = new SimpleAdapter(this, listItem,
  // 需要绑定的数据
    R.layout.simpleadapter_item,
    // 每一行的布局
    // 动态数组中的数据源的键对应到定义布局的View中
    new String[] { "userId", "userName", "userImage" }, new int[] {
      R.id.userId, R.id.userName, R.id.userImage });
 
  lv.setAdapter(mSimpleAdapter);// 为ListView绑定适配器
  lv.setOnItemClickListener(new OnItemClickListener() {
 
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
      long arg3) {
    // TODO Auto-generated method stub
    setTitle("你点击了第" + arg2 + "行");// 设置标题栏显示点击的行
    HashMap item = (HashMap) arg0.getItemAtPosition(arg2);
    String section = String
      .valueOf(item.get("userName").toString());// get每一行的数据的名字
    Toast.makeText(MySimpleAdapter.this, section, Toast.LENGTH_LONG)
      .show();
    }
  });
  }
}

2.配置文件

/Yunsheng/res/layout/activity_simpleadapter.xml
    
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_width="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_height="wrap_content"
    android:id="@+id/myListItem" 
    android:paddingBottom="3dip"
    android:paddingLeft="10dip">
  <!-- 添加一个ListView控件 -->
  <ListView
     android:id="@+id/lv"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     />   
</LinearLayout>

/Yunsheng/res/layout/simpleadapter_item.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >
 
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >
 
        <TextView
            android:id="@+id/userId"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:textSize="20dp" >
        </TextView>
 
        <TextView
            android:id="@+id/userName"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:textColor="#F00F11" >
        </TextView>
    </LinearLayout>
 
    <ImageView
        android:id="@+id/userImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:rotationX="30" />
 
</RelativeLayout>
