从资产的文件夹中的文本文件加载阵列（Android版） [英] Loading array from a text file in assets folder (Android)

问题描述

请

我知道这个问题已经被问了很多次，但我还是不能让我的code工作。

I know this question has been asked many times, but I still can't get my code to work.

我在叫words.txt资产文件夹中的文本文件。有每行一个词在文本文件中的每一行，没有空行。我希望把每一个字在数组中。

I have a text file in my assets folder called words.txt. There is one word per line in each line of that text file with no blank lines. I want to put every word in an array.

首先，我尝试使用扫描仪，但阅读许多计算器线程后，我发现我需要使用AssetManager。

First I tried using scanner, but after reading many stackoverflow threads I found out I needed to use AssetManager.

下面是我的尝试：

AssetManager assetManager = getAssets();
InputStream inputStream = assetManager.open("words.txt");

这给我的错误信息：默认构造函数不能处理由隐超级构造函数抛出的异常类型IOException异常... 之前，我连做别的。我不知道这意味着什么。

It gives me the error message: default constructor cannot handle exception type IOException thrown by implicit super constructor... before I even do anything else. I don't know what this means.

此外，望着API，好像InputStream中只能读取的字节。如何从文本文件中读取单词？

Also, looking at the api, it seems like InputStream can only read bytes. How can I read words from the text file?

线程是压倒性的，因为它看起来像每个答案提出了不同的方法，用InputStreams，BufferedStreams，FileInputStreams，文件，文件夹的RE，资产文件夹和许多其他语言，我不熟悉。我刚学来开发Android应用，并有有限的Java经验。

The threads are overwhelming because it seems like each answer proposes a different method, using InputStreams, BufferedStreams, FileInputStreams, File, Res folders, Asset folders, and lots of other language I am unfamiliar with. I am just learning to develop android apps and have limited java experience.

推荐答案

如下图所示你可以这样做：

You can do as shown below:

    try {
        BufferedReader bReader = new BufferedReader(new InputStreamReader(getAssets().open("file.txt")));
        ArrayList<String> values = new ArrayList<String>();
        String line = bReader.readLine();
        while (line != null) {
            values.add(line);
            line = bReader.readLine();
        }
        bReader.close();
        for (String v : values)
            Log.i("Array is ", v);
    } catch (IOException e) {
        e.printStackTrace();
    }
