java - 在 Android SDK 中导入文本文件

Question

过去几天我一直在尝试读取文件，并尝试按照其他答案进行操作，但没有成功。这是我目前必须导入文本文件的代码:

    public ArrayList<String> crteDict() {

    try {
        BufferedReader br = new BufferedReader
                (new FileReader("/program/res/raw/levels.txt"));
        String line;
        while ((line = br.readLine()) != null) {
            String[] linewrds = line.split(" ");
            words.add(linewrds[0].toLowerCase());
           // process the line.
        }
        br.close();


       }
     catch (FileNotFoundException fe){
        fe.printStackTrace();

它的目的是读取文本文件并创建一长串单词。它一直以 FileNotFoundException 结束。请让我知道任何答案。谢谢!

如果你的文件存放在android工程的res/raw文件夹下，你可以这样读取，这段代码必须在Activity类中，如this.getResources() 引用Context.getResources():

// The InputStream opens the resourceId and sends it to the buffer
InputStream is = this.getResources().openRawResource(R.raw.levels);
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String readLine = null;

try {
    // While the BufferedReader readLine is not null 
    while ((readLine = br.readLine()) != null) {
    Log.d("TEXT", readLine);
}

// Close the InputStream and BufferedReader
is.close();
br.close();

} catch (IOException e) {
    e.printStackTrace();
}
