我想在Android上运行Java代码。但是我对 Activity 不熟悉。如何在 Activity 上调用WordPuzzle?
Android Activity :
public class Puzzle extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
Java代码:
public class WordPuzzle {.....
public Set<String> findWords(char[][] puzzle, Set<String> words) {.....
private int findMinimumWordLength(Set<String> words) {.....
private Set<String> findPossibleWords(char[][] puzzle, int minimumWordLength) {.....
public void main(String args[]) {
WordPuzzle program = new WordPuzzle();
char[][] puzzle = {
{'F','Y','Y','H','N','R','D'},
{'R','L','J','C','I','N','U'},
{'A','A','W','A','A','H','R'},
{'N','T','K','L','P','N','E'},
{'C','I','L','F','S','A','P'},
{'E','O','G','O','T','P','N'},
{'H','P','O','L','A','N','D'}
};
Set<String> words = new HashSet<String>();
words.add("FRANCE");
words.add("POLAND");
words.add("JAPAN");
words.add("HOLLAND");
Set<String> wordsFound = program.findWords(puzzle, words);
for(String word : wordsFound) {
System.out.println(word);
}
}
}
}
最佳答案
public class Puzzle extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WordPuzzle wp = new WordPuzzle(); // you need to make main() a static function to avoid this
String args[] = {""};
wp.main(args);
}
但我认为
System.out.println()
不会起作用,至少在用户可以查看的地方不起作用。将layout.main更改为
TextView
,然后将输出放在此处
