android利用数据库实现搜索联想功能

核心提示：for (SearchUtil.Word word : words) {cursor.addRow(columnValuesOfWord(id++, word));}return cursor;}private Object[] columnValuesOfWord(long id, SearchUtil.Word w

for (SearchUtil.Word word : words) {

cursor.addRow(columnValuesOfWord(id++, word));

}

return cursor;

}

private Object[] columnValuesOfWord(long id, SearchUtil.Word word) {

return new Object[] { id, // _id

word.word, // text1

word.definition, // text2

word.word, // intent_data (included when clicking on item)

};

}

private static final String[] COLUMNS = { "_id",

SearchManager.SUGGEST_COLUMN_TEXT_1,

SearchManager.SUGGEST_COLUMN_TEXT_2,

SearchManager.SUGGEST_COLUMN_INTENT_DATA,// 数据传递到intenter中

};

@Override

public int update(Uri uri, ContentValues values, String selection,

String[] selectionArgs) {

return 0;

}
