Media Player启动停止启动 [英] Media Player start stop start

问题描述

我正在制作一个新的android声音应用程序.我单击了一个可单击的按钮以播放声音.但是我也希望它在第二次单击时停止播放声音.现在该部分工作正常，这就是问题所在，当我再次单击按钮再次播放声音时，它没有播放，媒体播放器完全停止了.我在论坛上看过，但似乎找不到可以帮助我的答案. 这是我的活动:

I am making a new android sound application. I made a clickable button to play sound when I click on it. But I also want it to stop playing sound when I click for the second time. That part works fine now here is the problem, when I click again on button to play sound again, it doesn't play it, Media player is completely stopped. I was looking on forums but I can't seem to find an answer that could help me. Here is my Activity:

  MediaPlayer mpButtonClick1;
MediaPlayer mpButtonClick2;

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

    final MediaPlayer mpButtonClick1 = MediaPlayer.create(this, R.raw.spalshm);
    final MediaPlayer mpButtonClick2 = MediaPlayer.create(this, R.raw.splashs);


    Button dugme = (Button) findViewById(R.id.dugme);
    dugme.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            if (mpButtonClick1.isPlaying()) {
                mpButtonClick1.stop();
                mpButtonClick1.reset();

            }
            else {              
                mpButtonClick1.start();

            }


        }   

    });

当我尝试编写mpButtonClick1.prepare();时我收到未处理的异常类型IOE异常的错误

When I try to write mpButtonClick1.prepare(); I get error Unhandled Exception Type IOE exception

推荐答案

使用以下代码更改您的课程:

Change your class with below code:

删除reset();.

初始化所有组件:

MediaPlayer mpButtonClick1;
MediaPlayer mpButtonClick2;

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

     mpButtonClick1 = MediaPlayer.create(this, R.raw.spalshm);
     mpButtonClick2 = MediaPlayer.create(this, R.raw.splashs);


    Button dugme = (Button) findViewById(R.id.dugme);
    dugme.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            if (mpButtonClick1.isPlaying()) {
                mpButtonClick1.stop();
             }
            else {              
                mpButtonClick1.start();
            }
         }   

    });
