我想创建一个带有自定义行的列表视图。我ListActivity
为每个行项创建了一个扩展类和一个 XML。我还添加了一个生成一些虚拟数据的方法。但这就是我卡住的地方。如何从我的主类中调用它并在我的列表视图中填充main.xml
?
自定义列表视图.java
public class CustomListView extends ListActivity {
private ArrayList<HashMap<String,String>> list;
public CustomListView(){
list = new ArrayList<HashMap<String,String>>();
SimpleAdapter adapter = new SimpleAdapter(
this,
list,
R.layout.custom_list_item,
new String[] {"pen","price","color"},
new int[] {R.id.text1,R.id.text2, R.id.text3});
populateList();
setListAdapter(adapter);
}
private void populateList() {
HashMap<String,String> temp = new HashMap<String,String>();
temp.put("pen","MONT Blanc");
temp.put("price", "200.00$");
temp.put("color", "Silver, Grey, Black");
list.add(temp);
HashMap<String,String> temp1 = new HashMap<String,String>();
temp1.put("pen","Gucci");
temp1.put("price", "300.00$");
temp1.put("color", "Gold, Red");
list.add(temp1);
HashMap<String,String> temp2 = new HashMap<String,String>();
temp2.put("pen","Parker");
temp2.put("price", "400.00$");
temp2.put("color", "Gold, Blue");
list.add(temp2);
HashMap<String,String> temp3 = new HashMap<String,String>();
temp3.put("pen","Sailor");
temp3.put("price", "500.00$");
temp3.put("color", "Silver");
list.add(temp3);
HashMap<String,String> temp4 = new HashMap<String,String>();
temp4.put("pen","Porsche Design");
temp4.put("price", "600.00$");
temp4.put("color", "Silver, Grey, Red");
list.add(temp4);
}
}
custom_list_item.xml
<?xml version="1.0" encoding="utf-8"?>
