今天在做一个功能的时候,要求必须是在一个listview下,有一段提示行的文字,自己的那个listview的adapter用的是cursoradapter,这样的话,处理布局的灵活性就大打折扣了。最开始的想法是改变item的布局,然后在adapter中处理,保证在listview加载到最后一行的时候,控制item中添加的textview显示,实现提示效果。但是,这时候会面临很多的问题。比如,最后一行点击事件,最后一行的下划线等。
后来,想到了另外一种方法,就是不再adapter中添加,而是直接在listview中添加,这个很好的解决了问题。代码如下
/* Vanzo:zhangshuli on: Sat, 24 Jan 2015 16:21:40 +0000 */ private View mAddSlideItem; private TextView mSearchResult; // End of Vanzo: zhangshuli public void onCreate1(Bundle icicle) { MmsLog.d(TAG,"onCreate"); initPlugin(this, getIntent()); sNeedRequery = true; final Uri u = getIntent().getData(); if (u != null && u.getQueryParameter("source_id") != null) { gotoComposeMessageActivity(u); return; } ContentResolver cr = getContentResolver(); mLayoutSearch = (RelativeLayout) findViewById(R.id.conv_second); mLayoutSearch.setVisibility(View.GONE); //得到想要添加的控件 mAddSlideItem = ((LayoutInflater) getSystemService( Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.search_mms_result, null); mSearchResult = (TextView) mAddSlideItem.findViewById(R.id.search_result); mSearchListView = (ListView) findViewById(R.id.list2); mSearchListView.setItemsCanFocus(true); mSearchListView.setFocusable(true); mSearchListView.setClickable(true); //在末尾添加控件 mSearchListView.addFooterView(mAddSlideItem); mTvEmpty = (TextView)findViewById(android.R.id.empty); setTitle(""); Contact.addListener(mContactListener); mQueryHandler2 = new AsyncQueryHandler(cr) { protected void onQueryComplete(int token, Object cookie, Cursor c) { try { if (searchProgressDialog != null && searchProgressDialog.isShowing()) { searchProgressDialog.setDismiss(true); searchProgressDialog.dismiss(); } } catch (IllegalArgumentException ex) { MmsLog.d(TAG,"Dialog.dismiss() IllegalArgumentException"); } if (mIsContentChanged) { sWaitSaveDraft = false; mIsContentChanged = false; } mIsQueryComplete = true; /// @} if (c == null) { /// M: Add for OP09: @{ mSearchListView.setFocusable(true); mSearchListView.setFocusableInTouchMode(true); mSearchListView.requestFocus(); // Remember the query if there are actual results if (cursorCount > 0) { SearchRecentSuggestions recent = ((MmsApp)getApplication()).getRecentSuggestions(); if (recent != null) { recent.saveRecentQuery(searchString, getString(R.string.search_history, cursorCount, searchString)); } }
虽然你在这里增加了自己的控件,但是,如果你想刷新这个控件的状态,这时候你需要跟listview刷新类似,也就是每次都要
