我试图让一个应用程序在Android的播放，暂停和停止一首歌只有一个按钮。

谁能告诉我如何才能让该应用程序？

 最后按钮bPlay =（按钮）findViewById（R.id.bPlay）;
            MediaPlayer的松1 = MediaPlayer.create（tutorialFour.this，R.raw.fluet）;
        按钮bStop层=（按钮）findViewById（R.id.bStop）;
        bPlay.setWidth（10）;
        song1.setOnCompletionListener（新OnCompletionListener（）{

            公共无效onCompletion（MediaPlayer的MP）{

                bPlay.setText（播放）;


            }
        }）;
        bPlay.setOnClickListener（新View.OnClickListener（）{

            公共无效的onClick（视图v）{
                // TODO自动生成方法存根
                B =真实;

                如果（bPlay.getText（）等于（播放）及。和b ==真）
                {

                    song1.start（）;

                    bPlay.setText（暂停）;
                    B = FALSE;
                }

                否则，如果（bPlay.getText（）。等于（暂停））
                {
                    X = song1.getCurrentPosition（）;
                    song1.pause（）;
                    bPlay.setText（恢复）;
                    Log.v（日志，+ X）;
                    B = FALSE;
                }
                否则，如果（bPlay.getText（）等于（恢复）及。和b ==真）
                {
                    song1.seekTo（X）;
                    song1.start（）;
                    bPlay.setText（暂停）;
                    B = FALSE;
                }


            }

        }）;
 

I have tried to make an application in android to play, pause and stop a song with one button only.

Can anyone show me how can I make that application?

final Button bPlay = (Button)findViewById(R.id.bPlay);
            MediaPlayer song1 = MediaPlayer.create(tutorialFour.this, R.raw.fluet);
        Button bStop = (Button)findViewById(R.id.bStop);
        bPlay.setWidth(10);
        song1.setOnCompletionListener(new OnCompletionListener() {

            public void onCompletion(MediaPlayer mp) {

                bPlay.setText("Play");


            }
        });
        bPlay.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                b=true;

                if(bPlay.getText().equals("Play") && b==true)
                {

                    song1.start();

                    bPlay.setText("Pause");
                    b=false;
                }

                else if(bPlay.getText().equals("Pause"))
                {
                    x=song1.getCurrentPosition();
                    song1.pause();
                    bPlay.setText("Resume");
                    Log.v("log",""+x);
                    b=false;
                }
                else if(bPlay.getText().equals("Resume") && b==true)
                {
                    song1.seekTo(x);
                    song1.start();
                    bPlay.setText("Pause");
                    b=false;
                }


            }

        });
