Java 如何在android studio中设置音频延迟？

我对这段代码的问题是，我的所有音频文件在同一时间播放。我正在尝试创建一个应用程序，根据您在EDITTEXT中键入的内容播放计算出的歌曲。我需要一种方法来延迟后续的每个音符一定的时间，以便它像一首歌一样播放。。。有没有办法在没有更多案例陈述的情况下做到这一点

我的java代码：

public class MainActivity extends Activity {


EditText edit;
Button button;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    edit  = (EditText) findViewById(R.id.box);
    button  = (Button) findViewById(R.id.button);

    button.setOnClickListener(new View.OnClickListener() {


        @Override
        public void onClick(View v) {
            String string = edit.getText().toString();
            char arr[]=string.toCharArray();
            for(int i=0;i<arr.length;i++){
                switch (arr[i]) {
                    case 'a':
                        MediaPlayer mp = MediaPlayer.create(getApplicationContext(), sample);
                        mp.start();

                        break;
                    case 'b':
                        MediaPlayer mp1 = MediaPlayer.create(getApplicationContext(), sample1);
                        mp1.start();

                        break;
                    case 'c':
                        MediaPlayer mp2 = MediaPlayer.create(getApplicationContext(), sample2);
                        mp2.start();

                        break;
                    case 'd':
                        MediaPlayer mp3 = MediaPlayer.create(getApplicationContext(), sample3);

要一个接一个地播放多个音频文件，您不必一个接一个地创建嵌套的onCompletionListener。您只需创建一个包含所有要播放的音频文件的数组并设置onCompletionListener即可。例如：

int[] myAudio = {R.raw.audio1, R.raw.audio2, R.raw.audio3};
int mTrackFinish = 0;
MediaPlayer mp = MediaPlayer.create(this, myAudio[0]);
mp.setOnCompletionListener(new OnCompletionListener() 
{
 @Override
 public void onCompletion(MediaPlayer mp)
 {
     mTrackFinish++;
     mp.reset();
     if(mTrackFinish < myAudio.length)
            // play some audio from list
        else
          mTrackFinish=0;
          mp.release();
          mp = null;  // either set counter to 0 and start again or call end of list

    }
});
mp.start();

int[]myAudio={R.raw.audio1，R.raw.audio2，R.raw.audio3}；
int mTrackFinish=0；
MediaPlayer mp=MediaPlayer.create（这个，myAudio[0]）；
mp.setOnCompletionListener（新的OnCompletionListener（）
{

不允许播放下一个音频。允许字符“b”播放。我想在前一个角色之后，准备并播放该系列中的下一个角色，无论它是什么。我已编辑了答案。此代码将在完成后一个接一个播放多个音频。P.令人惊讶的是，一个多月后突然出现了这个问题。
