android实现关键字搜索功能

//以关键字查找日记为例，主要是Sql语句

public ArrayList<DiaryBean> searchNotes(String keywords) {

if (keywords != null) {

ArrayList<DiaryBean> dList = new ArrayList<DiaryBean>();

//查询日记标题或内容含有关键字的记录

Cursor cusror = mDb.query(true, DATABASE_TABLE, new String[] { ROWID,

TITLE, BODY, CREATED, MOOD, WEATHER, COLOR, BACKGROUND, SIZE },

"TITLE like '%" + keywords + "%'"+" or BODY like '%" + keywords +"%'" , null, null, null, null, null);

while (cusror.moveToNext()) {

DiaryBean bean = new DiaryBean();

bean.setTitle(cusror.getString(cusror.getColumnIndex(TITLE)));

bean.setBody(cusror.getString(cusror.getColumnIndex(BODY)));

bean.setColor(cusror.getInt(cusror.getColumnIndex(COLOR)));

bean.setMood(cusror.getInt(cusror.getColumnIndex(MOOD)));

bean.setId(cusror.getInt(cusror.getColumnIndex(ROWID)));

bean.setTime(cusror.getString(cusror.getColumnIndex(CREATED)));

bean.setWeather(cusror.getInt(cusror.getColumnIndex(WEATHER)));

bean.setSize(cusror.getInt(cusror.getColumnIndex(SIZE)));

bean.setBackground(cusror.getInt(cusror

.getColumnIndex(BACKGROUND)));

dList.add(bean);

}

cusror.close();

return dList;

} else {

return null;

}
