如何在Android中阅读文本文件？

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

public String readTextFile(Context context, int resourceId) {
    StringBuilder stringBuilder = new StringBuilder();

    try {
        InputStream inputStream = context.getResources().openRawResource(resourceId);
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

        String line;
        while ((line = bufferedReader.readLine()) != null) {
            stringBuilder.append(line);
            stringBuilder.append("\n");
        }

        bufferedReader.close();
        inputStreamReader.close();
        inputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return stringBuilder.toString();
}

import android.content.Context;
import android.content.res.AssetManager;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public String readTextFile(Context context, String fileName) {
    StringBuilder stringBuilder = new StringBuilder();

    try {
        AssetManager assetManager = context.getAssets();
        InputStream inputStream = assetManager.open(fileName);
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

        String line;
        while ((line = bufferedReader.readLine()) != null) {
            stringBuilder.append(line);
            stringBuilder.append("\n");
        }

        bufferedReader.close();
        inputStreamReader.close();
        inputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return stringBuilder.toString();
}
