本文介绍了一个基于Android的应用中实现短信内容搜索的功能。通过用户输入的关键字，在本地数据库中查询匹配的短信记录，并将结果显示在列表中。涉及的技术包括SQLite数据库操作、适配器更新以及软键盘的显示与隐藏。

//在按钮点击事件里处理

bt_search.setOnClickListener(new OnClickListener() {

           public void onClick(View v) {

               String strSearch = ed_input.getText().toString();
               SQLiteDatabase db = VSmsDBUtil.createOrOpenDatabase();
               LogWrapper.i("search", "db = "+db);
               Cursor cursor =
               db.rawQuery("SELECT sTitle, sContent, sTime, sImage FROM msgtab where ( findItem like ?)",
               new String[]{"%"+strSearch+"%"});
               tempListSms = new ArrayList<TestSmsBean>();
               if( cursor != null ){
                       if( cursor.moveToFirst() ){
                           do{

                                          cursor.getString(0),
                                          cursor.getString(1),

                                 tempListSms.add(tsb);

                     }
                    cursor.close();
                    db.close();
