ListActivity下列表项打开新的Activity

创建ListCellData类

成员变量

private  String  listName = null;
private  Context context = null;         //主context
private  Intent  relatedIntent = null;//要打开的activity

构造函数

public ListCellData(Context context, String listName, Intent relatedIntent) {

this.listName = listName;
this.context = context;
this.relatedIntent = relatedIntent;
}

启动activity方法

public void startActivity(){

context.startActivity(relatedIntent);
}

注意toString方法，不重写的话listview会显示乱码

public String toString() {
// TODO Auto-generated method stub
return listName;
}

在mainActivity中填充数据

adapter = new ArrayAdapter<ListCellData>(this, android.R.layout.simple_expandable_list_item_1);
        setListAdapter(adapter);
        adapter.add(new ListCellData(MainActivity.this, "FileSave", new Intent(MainActivity.this,AtyFlieSave.class)));

//我要打开的是atyfilesave

重载onListItemClick方法

protected void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id);
    ListCellData data = adapter.getItem(position);      
    data.startActivity();
    }
