Java Can'；t读取文本文件并可以'；我找不到解决办法

我尝试过许多读取文件的方法，但我发现它们都不起作用。我没有使用默认库。我使用的框架是从

我试图读取它并将其逐行插入到字符串数组中。我尝试过的每个方法都需要一个上下文，但由于它的初始化方式与默认android应用程序不同，因此它没有使用getAssets的上下文。还有其他读取文本文件的方法吗

我试着使用这组代码，但它不起作用，因为它需要资产

    InputStream iS;
    resources = AndroidGame.resources;

    if (loadFromRawFolder) {
        int rID = resources.getIdentifier("raw/store_app", "raw", "com.cciamlazy.pixunited");
        iS = resources.openRawResource(rID);
    } else {
        iS = resources.getAssets().open(inFile);
    }
    byte[] buffer = new byte[iS.available()];
    iS.read(buffer);
    ByteArrayOutputStream oS = new ByteArrayOutputStream();
    oS.write(buffer);
    oS.close();
    iS.close();

此代码为我提供错误和资源

！=空

。给我一个错误：

android.content.res.Resources$NotFoundException: Resource ID #0x0

全类代码

package com.cciamlazy.pixunited;

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;

import android.app.Activity;
import android.content.res.Resources;


public class MapLoader extends Activity {

    private static Resources resources;

    public MapLoader() {
        resources = getResources();
    }

    public static String LoadFile(String fileName, boolean loadFromRawFolder) throws IOException {

        // Create a InputStream to read the file into
        InputStream iS;

        if (loadFromRawFolder) {
            // get the resource id from the file name
            // int rID = resources.getIdentifier(fileName, null, null);
            int rID = resources.getIdentifier("raw/store_app", "raw",
                    "com.cciamlazy.activity");
            // get the file as a stream
            iS = resources.openRawResource(rID);
        } else {
            // get the file as a stream
            iS = resources.getAssets().open(fileName);
        }

        // create a buffer that has the same size as the InputStream
        byte[] buffer = new byte[iS.available()];
        // read the text file as a stream, into the buffer
        iS.read(buffer);
        // create a output stream to write the buffer into
        ByteArrayOutputStream oS = new ByteArrayOutputStream();
        // write this buffer to the output stream
        oS.write(buffer);
        // Close the Input and Output streams
        oS.close();
        iS.close();

        // return the output stream as a String
        return oS.toString();
    }

}

希望这有助于

将这两行添加到您的活动中

private static Resources resources;

resources = getResources();

然后添加此方法

 public static String LoadFile(String fileName, boolean loadFromRawFolder)


            throws IOException {

        // Create a InputStream to read the file into
        InputStream iS;

        if (loadFromRawFolder) {
            // get the resource id from the file name
            // int rID = resources.getIdentifier(fileName, null, null);
            int rID = resources.getIdentifier("raw/store_app", "raw",
                    "com.example.activity");
            // get the file as a stream
            iS = resources.openRawResource(rID);
        } else {
            // get the file as a stream
            iS = resources.getAssets().open(fileName);
        }

        // create a buffer that has the same size as the InputStream
        byte[] buffer = new byte[iS.available()];
        // read the text file as a stream, into the buffer
        iS.read(buffer);
        // create a output stream to write the buffer into
        ByteArrayOutputStream oS = new ByteArrayOutputStream();
        // write this buffer to the output stream
        oS.write(buffer);
        // Close the Input and Output streams
        oS.close();
        iS.close();

        // return the output stream as a String
        return oS.toString();
    }

请发布一些代码“资源”在我的情况下不是一个变量。请参阅我编辑的答案。我不能使用getResources，因为我没有使用android应用程序的正常框架。我不使用res，甚至当我导入它时，我知道我必须创建一个名为GetResources的方法。你说的普通框架是什么意思？我真的不明白。我想在编写代码之前，请阅读android开发者网站。你可以在这里完整复制和粘贴代码。这对任何人都有帮助。我更新了我的代码，现在仍然可以给了我错误
