ListView组件与SimpleAdapter

记录两个ListView的简单小例子.其中使用到 了SimpleAdapter适配器。

 

1、不带图片

listview.xml

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:paddingLeft="10dip"
  android:paddingRight="10dip"
  android:paddingTop="1dip"
  android:paddingBottom="1dip">
    
    <TextView   
	    android:id="@+id/name"  
	    android:layout_width="180dip"  
	    android:layout_height="30dip"  
	    android:textSize="10pt"  
	    android:singleLine="true"  
  		/>   
  
	  <TextView   
	    android:id="@+id/phone"  
	    android:layout_width="fill_parent"  
	    android:layout_height="fill_parent"  
	    android:gravity="right"  
	    android:textSize="10pt"  
	  />
    
</LinearLayout>

 

ListViewActivity.java

public class ListViewActivity extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String,String>>();
        
        HashMap<String, String> map1 = new HashMap<String, String>();
        HashMap<String, String> map2 = new HashMap<String, String>();
        HashMap<String, String> map3 = new HashMap<String, String>();
        map1.put("name", "张三");
        map1.put("phone", "13800138000");
        map2.put("name", "李四");
        map2.put("phone", "13800138022");
        map3.put("name", "王武");
        map3.put("phone", "13800138033");
        
        list.add(map1);
        list.add(map2);
        list.add(map3);
        
        SimpleAdapter adapter = new SimpleAdapter(this,list,R.layout.info,
        							new String[]{"name","phone"},new int[]{R.id.name,R.id.phone});
        setListAdapter(adapter);
        
        
    }

	@Override
	protected void onListItemClick(ListView l, View v, int position, long id) {
		super.onListItemClick(l, v, position, id);
		Toast.makeText(ListViewActivity.this, ((HashMap)l.getItemAtPosition(position)).get("name").toString(), Toast.LENGTH_LONG).show();
	}

2、带有图片效果：

listviewtwo.xml

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  >
    <ImageView android:id="@+id/image"
    	android:layout_width="30px"
    	android:layout_height="30px"
    	android:layout_margin="5px"/>
    <LinearLayout android:id="@+id/linerlayout"
    	android:layout_width="wrap_content"
    	android:layout_height="fill_parent"
    	android:orientation="vertical"
    	android:gravity="center_vertical">
    	
    	<TextView android:id="@+id/name1"
    		android:layout_width="wrap_content"
    		android:layout_height="wrap_content"
    		android:textSize="20px"/>
    	
    	<TextView android:id="@+id/phone1"
    		android:layout_width="wrap_content"
    		android:layout_height="fill_parent"
    		android:textSize="10px"/>
    	
   </LinearLayout>
</LinearLayout>

 

 

ListViewTwoActivity.java

public class ListViewTwoActivity extends ListActivity{

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
ArrayList<HashMap<String, Object>> list = new ArrayList<HashMap<String,Object>>();
        
        HashMap<String, Object> map1 = new HashMap<String, Object>();
        HashMap<String, Object> map2 = new HashMap<String, Object>();
        HashMap<String, Object> map3 = new HashMap<String, Object>();
        map1.put("name", "张三");
        map1.put("phone", "13800138000");
        map1.put("image", R.drawable.icon);
        map2.put("name", "李四");
        map2.put("phone", "13800138022");
        map2.put("image", R.drawable.jinji1);
        map3.put("name", "王武");
        map3.put("phone", "13800138033");
        map3.put("image", R.drawable.jixugoucai);
        
        list.add(map1);
        list.add(map2);
        list.add(map3);
        list.add(map1);
        list.add(map2);
        list.add(map3);
        list.add(map1);
        list.add(map2);
        list.add(map3);
        list.add(map1);
        list.add(map2);
        list.add(map3);
        list.add(map1);
        list.add(map2);
        list.add(map3);
        list.add(map1);
        list.add(map2);
        list.add(map3);
        list.add(map1);
        list.add(map2);
        list.add(map3);
        
        SimpleAdapter adapter = new SimpleAdapter(this,list,R.layout.listviewtwoinfo,
        			new String[]{"name","phone","image"},new int[]{R.id.name1,R.id.phone1,R.id.image});
        
        setListAdapter(adapter);
	}
	
}
