android MediaPlayer 简易播放器的实现及类似斗地主音频池实现

一：android MediaPlayer 简易播放器的实现

（一）MediaPlayer实现前提1.音频来源途径(应用内，内存卡中的音频，网络上)

（二）代码块实现

public class MediaplayerActivity extends AppCompatActivity {    private MediaPlayer mediaPlayer;    private SeekBar seekBar;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_mediaplayer);        seekBar = (SeekBar) findViewById(R.id.seekbar);        seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {            @Override            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {            }            @Override            public void onStartTrackingTouch(SeekBar seekBar) {            }            @Override            public void onStopTrackingTouch(SeekBar seekBar) {                //获取拖动结束之后的位置                int progress = seekBar.getProgress();                //跳转到某个位置播放                mediaPlayer.seekTo(progress);            }        });    }    public void isPlayOrPause(View view) {        final ImageButton imageButton = (ImageButton) view;        if (mediaPlayer == null) {            //实例化MediaPlayer            //1.播放应用内//        mediaPlayer = MediaPlayer.create(this, R.raw.love);            //2.播放内存卡中音频文件            mediaPlayer = new MediaPlayer();            //设置类型            mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);            //设置音源            try {//                mediaPlayer.setDataSource(this, Uri.parse("file://netease/cloudmusic/Music/mylove.mp3"));                //3.播放网络音乐                mediaPlayer.setDataSource(this, Uri.parse("http://192.168.43.244:8080/dbqq.mp3"));                //准备一下(内存卡)//                mediaPlayer.prepare();                //准备（网络）                mediaPlayer.prepareAsync();            } catch (IOException e) {                e.printStackTrace();            }        } else if (mediaPlayer.isPlaying()) {            mediaPlayer.pause();            //把图标修改为播放的图标            imageButton.setImageResource(android.R.drawable.ic_media_play);        } else {            mediaPlayer.start();            //把图标修改为暂停的图标            imageButton.setImageResource(android.R.drawable.ic_media_pause);        }        //监听：准备完成的监听        mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {            @Override            public void onPrepared(MediaPlayer mp) {                mediaPlayer.start();                //把图标修改为暂停的图标                imageButton.setImageResource(android.R.drawable.ic_media_pause);                //获取音乐的总时长                int duration = mediaPlayer.getDuration();                //设置进度条的最大值为音乐的总时长                seekBar.setMax(duration);                new MyThread().start();            }        });    }    //开启线程    class MyThread extends Thread {        @Override        public void run() {            super.run();            while (seekBar.getProgress() <= seekBar.getMax()) {                //获取当前音乐播放的位置                int currentPosition = mediaPlayer.getCurrentPosition();                //让进度条动起来                seekBar.setProgress(currentPosition);            }        }    }}

（三）注意点

<uses-permission android:name="android.permission.INTERNET" />

二：android 类似斗地主音频池实现

public class PlayAnimalActivity extends AppCompatActivity {    private SoundPool soundPool;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_play_animal);        //实例化音频池        soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC,0);        //给音频池设置加载完成的监听        soundPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {            @Override            public void onLoadComplete(SoundPool soundPool, int i, int i1) {                soundPool.play(i,1,1,1,100,1);            }        });    }    public void playKFC(View view){        soundPool.load(this,R.raw.rooster,1);    }    public void playTwo(View view){        soundPool.load(this,R.raw.chimp,1);    }    public void playThree(View view){        soundPool.load(this,R.raw.crickets,1);    }    public void playFour(View view){        soundPool.load(this,R.raw.roar,1);    }    public void playDog(View view){        soundPool.load(this,R.raw.dogbark,1);    }    @Override    protected void onDestroy() {        super.onDestroy();        if(soundPool!=null){            soundPool.release();            soundPool=null;        }    }}
