Listitem_selector:

<? Xml version = "1.0" encoding = "UTF-8"?> <Selector xmlns: android = "http://schemas.android.com/apk/res/android"> <! -- Background color without focus --> <item android: drawable = "@ color/unfocused" android: state_window_focused = "false"/> <! -- Background color when the focus is obtained in non-touch mode --> <item android: drawable = "@ color/pressed" android: state_focused = "true" android: state_pressed = "true"/> <! -- Background color when you click in touch mode --> <item android: drawable = "@ color/pressed" android: state_focused = "false" android: state_pressed = "true"/> <! -- Selected background color --> <item android: drawable = "@ color/pressed" android: state_selected = "true"/> <! -- Background color when getting focus --> <item android: drawable = "@ color/pressed" android: state_focused = "true"/> </selector>

Font_selector:

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_focused="true" android:color="#ff0030" /> <!-- focused -->    <item android:state_pressed="true" android:color="#ff0030" /> <!-- pressed -->    <item android:state_selected="true" android:color="#ff0030" /> <!-- pressed -->    <item android:color="#222222" /> <!-- default --></selector>

Activity:

listView = (ListView) contentView1.findViewById(R.id.list);ArrayList<HashMap<String, String>> data = new ArrayList<HashMap<String, String>>();for (String i : name) {HashMap<String, String> map = new HashMap<String, String>();map.put("data", i);data.add(map);}SimpleAdapter simple = new SimpleAdapter(getActivity(), data,R.layout.layout_popup_item, new String[] { "data" },new int[] { R.id.text1 });listView.setAdapter(simple);

Note:

TextView also adds attributes

Android: duplicateParentState = "true"

In this way, the status of the ParentView will change.
