1.添加不同類型條目

 1 class MyAdapter extends BaseAdapter{ 2      3     //擷取資料配接器中項目類型的總數,修改成兩種(純文字,圖片+文字) 4     @Override 5     public int getViewTypeCount() { 6         return super.getViewTypeCount()+1; 7     } 8      9     //指定索引指向的項目類型,項目類型狀態代碼指定(0(複用系統),1)10     @Override11     public int getItemViewType(int position) {12         if(position == 0 || position == mCustomerList.size()+1){13             //返回0,代表純文字條目的狀態代碼14             return 0;15         }else{16             //返回1,代表圖片+文本條目狀態代碼17             return 1;18         }19     }20     21     //listView中添加兩個描述條目22     @Override23     public int getCount() {24         return mCustomerList.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                 //返回系統應用對應條目的對象36                 return mSystemList.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             //展示灰色純文字條目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("使用者應用("+mCustomerList.size()+")");63             }else{64                 holder.tv_title.setText("系統應用("+mSystemList.size()+")");65             }66             return convertView;67         }else{68             //展示圖片+文字條目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卡應用");84             }else{85                 holder.tv_path.setText("手機應用");86             }87             return convertView;88         }89     }90 }

 

2.常駐懸浮框使用

lv_app_list.setOnScrollListener(new OnScrollListener() {@Overridepublic void onScrollStateChanged(AbsListView view, int scrollState) {}@Overridepublic void onScroll(AbsListView view, int firstVisibleItem,int visibleItemCount, int totalItemCount) {//滾動過程中調用方法//AbsListView中view就是listView對象//firstVisibleItem第一個可見條目索引值//visibleItemCount當前一個螢幕的可見條目數//總共條目總數if(mCustomerList!=null && mSystemList!=null){if(firstVisibleItem>=mCustomerList.size()+1){//滾動到了系統條目tv_des.setText("系統應用("+mSystemList.size()+")");}else{//滾動到了使用者應用條目tv_des.setText("使用者應用("+mCustomerList.size()+")");}}}});

 

3.activity_app_manager.xml

<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>
