1. Add different types of entries

1 class MyAdapter extends BaseAdapter {2 3 // obtain the total number of entry types in the data adapter, and change it to two types (plain text, image + text) 4 @ Override 5 public int getViewTypeCount () {6 return super. getViewTypeCount () + 1; 7} 8 9 // specify the entry type pointed to by the index, specify the entry type status code (0 (Reuse System), 1) 10 @ Override11 public int getItemViewType (int position) {12 if (position = 0 | position = mCustomerList. size () + 1) {13 // return 0, representing the status code 14 return 0; 15} else {16 // return 1, represents the image + text entry status code 17 return 1; 18} 19} 20 21 // Add two description entries 22 @ Override23 public int getCount () {24 return mCustomerList in listView. size () + mSystemList. size () + 2; 25} 26 27 @ Override28 public AppInfo getItem (int position) {29 if (position = 0 | position = mCustomerList. size () + 1) {30 return null; 31} else {32 if (position <mCustomerList. size () + 1) {33 return mCustomerList. get (position-1); 34} else {35 // return the 36 return mSystemList object corresponding to the system application. get (position-mCustomerList. size ()-2); 37} 38} 39} 40 41 @ Override42 public long getItemId (int position) {43 return position; 44} 45 46 @ Override47 public View getView (int position, View convertView, ViewGroup parent) {48 int type = getItemViewType (position); 49 50 if (type = 0) {51 // display gray plain text entries 52 ViewTitleHolder holder = null; 53 if (convertView = null) {54 convertView = View. inflate (getApplicationContext (), R. layout. listview_app_item_title, null); 55 holder = new ViewTitleHolder (); 56 holder. TV _title = (TextView) convertView. findViewById (R. id. TV _title); 57 convertView. setTag (holder); 58} else {59 holder = (ViewTitleHolder) convertView. getTag (); 60} 61 if (position = 0) {62 holder. TV _title.setText ("user application (" + mCustomerList. size () + ")"); 63} else {64 holder. TV _title.setText ("System Application (" + mSystemList. size () + ")"); 65} 66 return convertView; 67} else {68 // display image + text entry 69 ViewHolder holder = null; 70 if (convertView = null) {71 convertView = View. inflate (getApplicationContext (), R. layout. listview_app_item, null); 72 holder = new ViewHolder (); 73 holder. iv_icon = (ImageView) convertView. findViewById (R. id. iv_icon); 74 holder. TV _name = (TextView) convertView. findViewById (R. id. TV _name); 75 holder. TV _path = (TextView) convertView. findViewById (R. id. TV _path); 76 convertView. setTag (holder); 77} else {78 holder = (ViewHolder) convertView. getTag (); 79} 80 holder. iv_icon.setBackgroundDrawable (getItem (position ). icon); 81 holder. TV _name.setText (getItem (position ). name); 82 if (getItem (position ). isSdCard) {83 holder. TV _path.setText ("SD card application"); 84} else {85 holder. TV _path.setText ("mobile app"); 86} 87 return convertView; 88} 89} 90}

 

2.Resident Floating frame usage

Listener (new OnScrollListener () {@ Overridepublic void onScrollStateChanged (AbsListView view, int scrollState) {}@ Overridepublic void onScroll (AbsListView view, int cursor, int visibleItemCount, int totalItemCount) {// call method during the rolling process // view in AbsListView is the index value of the first visible entry in the listView object // firstVisibleItem // visibleItemCount number of visible entries on the current screen // total number of entries if (mCustomerList! = Null & mSystemList! = Null) {if (firstVisibleItem> = mCustomerList. size () + 1) {// scroll to the system entry TV _des.setText ("System Application (" + mSystemList. size () + ")");} else {// scroll to the user application entry TV _des.setText ("user application (" + mCustomerList. size () + ")");}}}});

<FrameLayout android:layout_width="match_parent"android:layout_height="wrap_content"><ListView android:id="@+id/lv_app_list"android:layout_width="match_parent"android:layout_height="wrap_content"></ListView><TextView android:background="#ccc"android:id="@+id/tv_des"android:textColor="#000"android:textSize="18sp"android:layout_width="match_parent"android:layout_height="wrap_content"/></FrameLayout>
