在上一次修复之后，我现在有一个新问题。有人建议提出一个新问题，所以就在这里！它仍然强制关闭，但现在在一条新线上。
public void AI(String text) {
// initiate new lists to be on the safe side
List<String> indexer = new ArrayList<String>();
List<String> sentence = new ArrayList<String>();
List<String> explode = new ArrayList<String>();
List<String> ary = new ArrayList<String>();
explode = Arrays.asList(text.split(" "));
// initiate randint and trigger variable
Random rand = new Random();
int randint = rand.nextInt(explode.size());
// initiate the trigger variable
String trigger = explode.get(randint);
//check if word exists in database and add if it not.
int i = 0;
for(String word : explode) {
if(common.get(word) == null) {
words.add(word);
common.put(word, 1);
context.put(word, explode);
pos.put(word, i);
length.put(word, explode.size());
if(word.equals(trigger)) {
ary = new ArrayList<String>(explode);
}
}else{
common.put(word, common.get(word)+1 );
}
i++;
}
// fill the arraylist sentence with words to be used, some in context, some random from the database.
for(int i2 = 0; i2 < length.get(trigger); i2++ ) {
randint = rand.nextInt(length.get(trigger));
if(randint < length.get(trigger)/2) {
//
if(ary.get(i2)!=null) {
sentence.add(ary.get(i2));
}
}else{
sentence.add(words.get(rand.nextInt(words.size())));
}
}
// use to the pos-hashmap to check at which index the word was detected at, if not place it at the deliberate index.
for(int i3 = 0; i3 < sentence.size(); i3++) {
if(sentence.get(i3)!=null) {
indexer.add(pos.get(sentence.get(i3)), sentence.get(i3));
}
}
// compose the final string that is to be passed to the speak function
for(int i4 = 0; i4 < indexer.size(); i4++) {
say = say + indexer.get(i4)+" ";
}
// pass the string to the speak function
mTts.speak(say, TextToSpeech.QUEUE_FLUSH, null);
// removing final string to be ready for next iteration
say = "";
// end of AI stuff
}
变量：
// arraylists
public List<String> explode = new ArrayList<String>();
public List<String> words = new ArrayList<String>();
public List<String> sentence = new ArrayList<String>();
public List<String> indexer = new ArrayList<String>();
// hashmaps
public Map<String, Integer> common = new HashMap<String, Integer>();
public Map<String, List<String>> context = new HashMap<String, List<String>>();
public Map<String, Integer> pos = new HashMap<String, Integer>();
public Map<String, Integer> length = new HashMap<String, Integer>();
//strings
public String say;

日志猫在尖叫什么：
第一的：
sentence.add(words.get(rand.nextInt(words.size())));
第二：
for(int i3 = 0; i3 < sentence.size(); i3++) {
if(sentence.get(i3)!=null) {
indexer.add(pos.get(sentence.get(i3)), sentence.get(i3));
}
}
如果有人能帮助我再次破解这个谜题，我会非常高兴！
