不带括号和逗号打印阵列 [英] Print array without brackets and commas

问题描述

我有previously写了一个刽子手游戏在学校我的Java类。我现在正在将它移植到Android和遇到的一些问题。原始的Java程序写的所有输出到控制台。现在我必须以某种方式beutify输出，使其适合，我设计了布局。

I have previously written a Hangman game for my java class in school. I am now currently porting it to Android and have met a few problems. The original java program wrote all outputs to the console. Now i have to somehow beutify the output so that it fits the layout that i have designed.

如何打印不带括号和逗号的数组？该数组包含斜杠，并得到一个更换时，其中一个正确的字母是猜测。

How do i print an array without the brackets and commas? The array contains slashes and gets replaced one by one when the correct letter is guessed.

我使用ArrayList类的通常的ToString（）函数，我的输出格式，如：[A，N，D，R，O，I，D]。我想将它打印出数组作为一个字符串。

I am using the usual .toString() function of the ArrayList class and my output is formatted like: [ a, n, d, r, o, i, d ]. I want it to simply print out the array as a single string.

这个问题似乎很简单，但我一直没能找到一个解决的办法。不使用搜索功能或者

This problems seems so simple although i haven't been able to find a solution to it. Not by using the search function either.

我填用code此位的数组：

I fill the array using this bit of code:

for(int i = 0;i<secretWordLength;i++){
        hiddenArray.add(secretWord.substring(i,i+1));
        publicArray.add("-");
    }

和我打印出来是这样的：

And i print it like this:

final TextView currentWordView = (TextView) findViewById(R.id.CurrentWord);
    currentWordView.setText(publicArray.toString());

任何帮助将AP preciated

Any help would be appreciated

推荐答案

基本上不使用 ArrayList.toString（） - 打造串起来为自己。例如：

Basically, don't use ArrayList.toString() - build the string up for yourself. For example:

StringBuilder builder = new StringBuilder();
for (String value : publicArray) {
    builder.append(value);
}
String text = builder.toString();

（我个人不会把变量 publicArray 时，它实际上不是一个数组，顺便说一句。）

(Personally I wouldn't call the variable publicArray when it's not actually an array, by the way.)
