另外一种写法的intent跳转

public class Test extends ListActivity {

private ArrayAdapter<Item> adapter;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Item[] items = {
new Item(TestPanels.class, "Test Panels"),
new Item(TestSwitcher.class, "Test Switcher"),
new Item(TestSmoothButton.class, "Test SmoothButton"),
new Item(TestInterpolators.class, "Test Interpolators"),
new Item(TestTheme.class, "Test Theme"),
new Item(TestVirtualKeyboard.class, "Test Virtual Keyboard"),
new Item(TestCustomTitle.class, "Test Custom Title"),
};
adapter = new ArrayAdapter<Item>(this, R.layout.simple_list_item_1, items);
setListAdapter(adapter);
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
startActivity(adapter.getItem(position));
}

class Item extends Intent {
String s;
public Item(Class<?> c, String s) {
super(Test.this, c);
this.s = s;
}

@Override
public String toString() {
return s;
}
}
}
