Searchable String-Array, Android?

Question

How can I search through an String-Array? I've got an dictionary app and the words are saved in a String-Array and it would be user-friendlier, if you could search for the word you want to look up, instead of looking its way to the word. Can somebody help?

Thanks.

Answer 1

Not entirely sure what you are looking for- do you want to see if the word is in the array, or what is the goal? If you want the user to get to the word faster, changing the string-array will not help the UI jump to the right place.

If you want it to be like Google suggest you could take your array and make a tree data object, which each node representing a letter in a word. Then if the user types a, you go into that node and offer possible words.

Answer 2

您可以使用Arrays.binarySearch（）方法从排序后的数组中搜索元素。

Answer 3

You can try using an ArrayList instead. Then you can see if the word is in your 'dictionary' by using the contains method, ex:

ArrayList <String> myDictionary = new ArrayList<String>();
myDictionary.add(new String("foo"));
myDictionary.add(new String("bar"));


...
// To check if the word exists in your dictionary.
if (myDictionary.contains(new String("word_to_look_up")))
{
}
