自定义 listivew (android)

刚学 listview ，参考网上的教程

http://www.cnblogs.com/allin/archive/2010/05/11/1732200.html

自己实现了一个 listview ，使用的是 SimpleAdapter ，稍微有点改动

代码如下：

 

 

public class SListViewActivity extends Activity {
    /** Called when the activity is first created. */
 private ListView iLv;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        iLv = (ListView) this.findViewById(R.id.lv);
        SimpleAdapter ada = new SimpleAdapter(this,getData(),R.layout.vlist,new String[]{"title","info","img"},
          new int[]{R.id.title,R.id.info,R.id.img});
        iLv.setAdapter(ada);

    }
    private List<Map<String,Object>> getData()
    {
     List<Map<String,Object>> list = new ArrayList<Map<String,Object>>();
     Map<String,Object> map = new HashMap<String,Object>();
     map.put("title", "G1");
     map.put("info","google");
     map.put("img",R.drawable.i1);
     list.add(map);
     
     map = new HashMap<String,Object>();
     map.put("title","G2");
     map.put("info","google 2");
     map.put("img", R.drawable.i1);
     list.add(map);
     
     return list;
    }

xml 代码

main.xml

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ListView 
        android:id="@+id/lv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        />

</LinearLayout>

 

vlist.xml   这个是自定义  listview 的布局文件

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
        
        <ImageView 
            android:id="@+id/img"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="3px"
            />
        <LinearLayout 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            >
            <TextView 
                android:id="@+id/title"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor = "#ffffff"
                android:textSize  = "22px"
                />
            <TextView
                android:id="@+id/info"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor = "#ffffff"
                android:textSize  = "12px"
                />
        </LinearLayout>
</LinearLayout>

 

在刚做出来后，一直没有办法运行，最终发现 TextView 这里写错了，改正确后就可以运行了。
