我想要合并两个.mp3或任何音频文件,并播放最后一个mp3文件.但是当我组合两个文件时,最终的文件大小是可以的,但是当我试图播放它只是播放第一个文件,我已经尝试过SequenceInputStream或字节数组,但我无法得到确切的结果,请帮助我.

我的代码如下：

public class MerginFileHere extends Activity {
public ArrayList<String> audNames;
byte fileContent[];
byte fileContent1[];
FileInputStream ins,ins1;
FileOutputStream fos = null;
String combined_file_stored_path = Environment
        .getExternalStorageDirectory().getPath()
        + "/AudioRecorder/final.mp3";

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    audNames = new ArrayList<String>();
    String file1 = Environment.getExternalStorageDirectory().getPath()
            + "/AudioRecorder/one.mp3";

    String file2 = Environment.getExternalStorageDirectory().getPath()
            + "/AudioRecorder/two.mp3";

    File file = new File(Environment.getExternalStorageDirectory()
            .getPath() + "/AudioRecorder/" + "final.mp3");

    try {
        file.createNewFile();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    audNames.add(file1);
    audNames.add(file2);

    Button btn = (Button) findViewById(R.id.clickme);
    btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            createCombineRecFile();
        }
    });
}

public void createCombineRecFile() {
    // String combined_file_stored_path = // File path in String to store
    // recorded audio

    try {
        fos = new FileOutputStream(combined_file_stored_path,true);
    } catch (FileNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

        try {
            File f = new File(audNames.get(0));
            File f1 = new File(audNames.get(1));
            Log.i("Record Message","File Length=========>>>" + f.length()+"------------->"+f1.length());


            fileContent = new byte[(int) f.length()];
            ins = new FileInputStream(audNames.get(0));
            int r = ins.read(fileContent);// Reads the file content as byte

            fileContent1 = new byte[(int) f1.length()];
            ins1 = new FileInputStream(audNames.get(1));
            int r1 = ins1.read(fileContent1);// Reads the file content as byte
                                            // from the list.






            Log.i("Record Message","Number Of Bytes Readed=====>>>" + r);

            //fos.write(fileContent1);// Write the byte into the combine file.


            byte[] combined = new byte[fileContent.length + fileContent1.length];

            for (int i = 0; i < combined.length; ++i)
            {
                combined[i] = i < fileContent.length ? fileContent[i] : fileContent1[i - fileContent.length];
            }
            fos.write(combined);
            //fos.write(fileContent1);*



        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    try {
        fos.close();
        Log.v("Record Message","===== Combine File Closed =====");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
}
