SimpleAdapter adds two elements do not show how the content? Great God seeking help 


  
android: orientation = "horizontal" 
android: layout_width = "fill_parent" 
android: layout_height = "fill_parent"> 

<-! Define a List -> 
android: id = "@ + id / mylist" 
android: layout_width = "fill_parent" 
android: layout_height = "fill_parent" /> 
<-! ImageView defined as part List -> 
android: id = "@ + id / header" 
android: layout_width = "wrap_content" 
android: layout_height = "wrap_content" 
android: paddingLeft = "2dp" /> 
<-! TextView defined as part List -> 
android: id = "@ + id / name" 
android: layout_width = "wrap_content" 
android: layout_height = "wrap_content" 
android: textSize = "16dp" 
android: gravity = "center_vertical" 
android: paddingLeft = "10dp" /> 

 

 public class SimpleAdapterActivity extends Activity {

private String [] names = new String [] {
"Zhao", "money two", "three Sun", "John Doe", "Friday", "Wu six", "Zheng seven", "bastard" 
}; 
private int [] imageIds = new int [] {
R.drawable.number_glod_img_2, 
R.drawable.number_glod_img_3, 
R.drawable.number_glod_img_4, 
R.drawable.number_glod_img_5, 
R.drawable.number_glod_img_6, 
R.drawable.number_glod_img_7, 
R.drawable.number_glod_img_8, 
R.drawable.number_glod_img_9, 
}; 
@ Override 
protected void onCreate (Bundle savedInstanceState) {
/ / TODO Auto-generated method stub 
super.onCreate (savedInstanceState); 
setContentView (R.layout.simpleadapter_listview_main); 
/ / Create a List collection whose elements are Map 
List > listItems = new ArrayList > (); 

for (int i = 0; i Map  list = new HashMap  (); 

list.put ("header", imageIds [i]); 
list.put ("personName", names [i]); 

listItems.add (list); 
} 
/ / Create a SimpleAdapter 
SimpleAdapter simpleAdapter = new SimpleAdapter (this, 
(List >) listItems, 
R.layout.simpleadapter_listview_main, 
new String [] {"header", "personName"}, 
new int [] {R.id.header, R.id.name}); 

ListView listView = (ListView) findViewById (R.id.mylist); 
/ / Set the ListView Adapter 
listView.setAdapter (simpleAdapter); 
} 
}
