在android中,如何在不使用html格式的情况下格式化如下所示的单个textview?

您可以使用此函数以编程方式执行此操作

val text = "This is my first text view this is my second textview this is my third textview"
textView.text = proxyWifi.textFormation(text)

public String textFormation(String text){
    String result = "";
    String[] sentenceWords = text.split(" ");
    List<String> newSentenceWords = new ArrayList<>();
    textRec(sentenceWords, newSentenceWords, sentenceWords.length -1, 0, "");

    int spacing = 0;
    for(int i = newSentenceWords.size() -1 ; i >= 0 ; i--){
        if(i == newSentenceWords.size() -1)
            result = newSentenceWords.get(i);
        else{
            result += "\n";
            spacing += (newSentenceWords.get(i + 1).length() - newSentenceWords.get(i).length())/2;

            for(int j = 0 ; j < spacing ; j++){
                result += " ";
            }

            result += newSentenceWords.get(i);
        }
    }

    return result;

}

public void textRec(String[] words, List<String> newWords, int indexWords, int indexNewWords, String sentence){
    Log.e("sentence", sentence);
    if(indexWords >= 0){
        if(indexNewWords == 0) {
            newWords.add(words[indexWords]);
            textRec(words, newWords, indexWords - 1, ++indexNewWords, "");
        }else{
            if(newWords.get(indexNewWords - 1).length() >= sentence.length())
                if(sentence.isEmpty())
                    textRec(words, newWords, indexWords - 1, indexNewWords, words[indexWords]);
                else
                    textRec(words, newWords, indexWords - 1, indexNewWords,  words[indexWords] + " " + sentence);
            else {
                newWords.add(sentence);
                textRec(words, newWords, indexWords , ++indexNewWords, "");
            }
        }
    }else{
        if(sentence.isEmpty()){
            return;
        }else{
            newWords.set(indexNewWords - 1 ,sentence + " " + newWords.get(indexNewWords - 1)) ;
        }
    }
}

没有默认的实现。此外,您无法找到执行此操作的行号。 所以你必须把句子分成多行。使用 \n 重心 文本视图 .

   if you use \n then your next line will be start from      

   This is my first textview
   <here> 
        <not here>

第一 将文本字符串分为多个部分(注意:-(n+1)第n部分应小于第n部分和deff。应为两端空间)。

创建具有垂直方向和重心的线性布局。

第三 在该阵列上循环。 在循环中,创建一个具有重心的新textview,并将文本设置为该视图。 并将此电视添加到linearLayout。

就是这样。

这可能有用
