一个因为粗心的Bug
/** * 数据绑定,分页显示 */ private void updataMenu(final EditText search) { if(listwz==null) { return; } pageID =0; listwz.setAdapter(null); FilterArray = new JSONArray(); FilterArray = usedatabase.WzArray(search.getText().toString(), pageID,WzLbID); // pageID = 1; //Bug 少查10条数据,但不影响速查 wzadapter = new WzAdapter(context, FilterArray,search); listwz.setAdapter(wzadapter); listwz.setOnScrollListener(new OnScrollListener() { int lastitem = 0; @Override public void onScrollStateChanged(AbsListView view, int scrollState) { // TODO Auto-generated method stub if(scrollState == OnScrollListener.SCROLL_STATE_IDLE && listwz.getCount()-lastitem<1) { if(WzLbID.equals("")) { pageID +=1; //把原来的加到一个新的Array里面 NewArray = new JSONArray(); NewArray = usedatabase.WzArray(search.getText().toString(), pageID,WzLbID); try { for(int i=0;i<NewArray.length();i++) { JSONObject item = (JSONObject)NewArray.get(i); FilterArray.put(item); } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } int currentPostition = listwz.getFirstVisiblePosition(); WzAdapter adapter = new WzAdapter(context, FilterArray,search); listwz.setAdapter(adapter); listwz.setSelectionFromTop(currentPostition+1, 0); } else { if(usedatabase.WzArray(search.getText().toString(), pageID,WzLbID).length()>FilterArray.length()) { pageID +=1; //把原来的加到一个新的Array里面 NewArray = new JSONArray(); NewArray = usedatabase.WzArray(search.getText().toString(), pageID,WzLbID); try { for(int i=0;i<NewArray.length();i++) { JSONObject item = (JSONObject)NewArray.get(i); FilterArray.put(item); } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } int currentPostition = listwz.getFirstVisiblePosition(); WzAdapter adapter = new WzAdapter(context, FilterArray,search); listwz.setAdapter(adapter); listwz.setSelectionFromTop(currentPostition+1, 0); } } } } @Override public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) { // TODO Auto-generated method stub lastitem = visibleItemCount+firstVisibleItem; } }); }
在按类别分页查询时候,默认为从10-0开始,查过一次后加了1,然后会照成10-10这10条数据查不出来,在大数据时候这10条数据很难发现,今天一个测试库只有26条数据,总是就加载16条数据,百思不得其解,检查代码才发现,真是粗心。
