播放和停止的一键 [英] Play and Stop in One button

问题描述

我是新手，我试图使播放的音频播放和停止仅1按钮，但我有麻烦了。

i'm newbie, i'm tried to make play audio play and stop for 1 button only, but i'm in trouble now.

如果我触碰时，音频播放按钮，它不会停止，即使再播放音频，使一个​​双音。

if i touch a button when audio is playing, it doesn't stop, even playing audio again and make a double sound.

这是我的code

public class ProjectisengActivity extends Activity{
    ImageButton mainkan;
    MediaPlayer mp;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test2);

        mainkan=(ImageButton)findViewById(R.id.imageButton1);
        mainkan.setOnClickListener(new OnClickListener(){
             @Override
            public void onClick(View v){

                go();
             }

            });

         public void go(){
    mp=MediaPlayer.create(ProjectisengActivity.this, R.raw.test);
    if(mp.isPlaying()){
        mp.stop();
        try {
            mp.prepare();
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        mp.seekTo(0);
}
    else {
    mp.start();

    }

推荐答案

尝试以下code。在去功能......

try below code in go function....

public void go() {
  if(mp == null) {
    mp=MediaPlayer.create(ProjectisengActivity.this, R.raw.test);
  }

  if(mp.isPlaying()){
    mp.stop();
    try {
        mp.prepare();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    mp.seekTo(0);
  }
  else {
   mp.start();
  }
}
