在上次修复之后,我现在有一个新问题。有人建议你问一个新问题,就是这样! 它仍然强制关闭,但现在在一条新的线上

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

logcats在尖叫什么:

第一:

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));   
                                                                       }
                                            }
for(inti3=0;i3<句子大小();i3++){
如果(语句get(i3)!=null){
索引器.add(pos.get(句子.get(i3)),句子.get(i3));
}
}

如果有人能帮我再次解开这个谜,我会非常高兴的

嗯,我不确定哪一行是186和188(这两行抛出边界外异常)。但看看这个循环,我有一些建议:

for(int i2 = 0; i2 < length.get(trigger); i2++ ) {
看起来您希望有50/50的机会:将原始单词添加到
句子中

        if(ary.get(i2)!=null) {
            sentence.add(ary.get(i2));
        }
    }else{
        sentence.add(words.get(rand.nextInt(words.size())));
    }
}    
。。。一个随机单词到
句子

我还认为这可能引发异常:

        if(ary.get(i2)!=null) {
            sentence.add(ary.get(i2));
因为您正在对照
length.get(trigger)
not
ari.size()
检查
i2
的有效性。现在请记住,
ary
只是
explode
的一个副本

让我们把这个循环压缩成:

for(String word : explode) {
    if(rand.nextInt(1)) // 50/50 chance of being false or true (0 or 1)
        sentence.add(word);
    else
        sentence.add(words.get(rand.nextInt(words.size())));
}

看看剩下的两个循环,如果你为每个循环应用一个相似的循环,你将能够压缩和加速这些循环。我不知道该应用程序的其余代码,但您可以完全删除一些列表和地图。干杯

第186行真的是
语句.add(words.get(rand.nextInt(words.size()))?因为
text
不能为空,这意味着
words
应该至少包含一个值,这行应该可以工作…是的,我明白你的意思,我认为问题在第二个疑点之内。通过预先缩放arraylist解决了这个问题,但现在我遇到了一个新问题,为什么这里返回indexoutofbounds?如果(ary.get(i2)!=null){session.add(ary.get(i2));}Edit:nvm,现在它又坏了。如果ary.size()是,比如说,10,而i2是10或更多,这将导致异常。看看我的答案。谢谢!成功了!现在只有i3循环返回indexoutofboundexception.ok,通过在i3之前添加此循环来修复它。对于(int i2=0;i2 if(ary.get(i2)!=null) { sentence.add(ary.get(i2));
for(String word : explode) {
    if(rand.nextInt(1)) // 50/50 chance of being false or true (0 or 1)
        sentence.add(word);
    else
        sentence.add(words.get(rand.nextInt(words.size())));
}
