Android Audio SeekBar

Je suis en train de créer quelque chose où un seul fichier audio est lu et peut être mis en pause et manipulé avec un progrès/barre de recherche. Je veux avoir une image prise de la plupart de l'écran, puis une pièce de théâtre bouton pause en bas à gauche et la barre vers la droite du bouton. Tout fonctionne de la seekbar, ce qui n'est pas le lien de l'audio. Ma barre de progression de programmation est probablement un gâchis parce que si elles sont prises à partir de plusieurs que j'ai vu sur internet, mais ils sont pour la plupart très confus pour moi comme ils le sont pour le lecteur de musique apps pas pour la lecture d'un fichier audio unique.

Quelqu'un pourrait-il m'aider avec la barre de progression? Tout autres conseils sur l'amélioration de ma programmation serait trop grand.

(Je suis très nouveau pour android et de programmation juste pour vous avertir)

C'est mon Java:

MediaPlayer mediaPlayer;
Button buttonPlayPause;
ImageView Image;
SeekBar seekBar;
private int stateMediaPlayer;
private final int stateMP_NotStarter = 0;
private final int stateMP_Playing = 1;
private final int stateMP_Pausing = 2;
int total;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playerwere);
Image = (ImageView) findViewById(R.id.pdfview);
Image.setImageResource(R.drawable.wereim);
seekBar = (SeekBar) findViewById(R.id.seekBar);
buttonPlayPause = (Button) findViewById(R.id.playpause);
buttonPlayPause.setOnClickListener(buttonPlayPauseOnClickListener);
seekBar.setOnSeekBarChangeListener(seekBarOnSeekListener);
initMediaPlayer();
Thread currentThread = new Thread(this);
currentThread.start();
}
private void initMediaPlayer() {
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(were.this, R.raw.were);
stateMediaPlayer = stateMP_NotStarter;
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer arg0) {
//TODO Auto-generated method stub
total = mediaPlayer.getDuration();
}
});
seekBar.setProgress(0);
seekBar.setMax(total);
}
Button.OnClickListener buttonPlayPauseOnClickListener = new Button.OnClickListener() {
@Override
public void onClick(View v) {
//TODO Auto-generated method stub
switch (stateMediaPlayer) {
case stateMP_NotStarter:
mediaPlayer.start();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
stateMediaPlayer = stateMP_Playing;
break;
case stateMP_Playing:
mediaPlayer.pause();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_play);
stateMediaPlayer = stateMP_Pausing;
break;
case stateMP_Pausing:
mediaPlayer.start();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
stateMediaPlayer = stateMP_Playing;
break;
}
}
};
SeekBar.OnSeekBarChangeListener seekBarOnSeekListener = new SeekBar.OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
//TODO Auto-generated method stub
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
//TODO Auto-generated method stub
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
//TODO Auto-generated method stub
if (fromUser) {
mediaPlayer.seekTo(progress);
seekBar.setProgress(progress);
}
}
};
@Override
public void run() {
//TODO Auto-generated method stub
try {
while (mediaPlayer != null) {
int currentPosition = mediaPlayer.getCurrentPosition();
Message msg = new Message();
msg.what = currentPosition;
threadHandler.sendMessage(msg);
}
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
private Handler threadHandler = new Handler() {
public void handleMessage(Message msg) {
seekBar.setProgress(msg.what);
}
};

Et c'est ce que mon java était avant j'ai essayé d'utiliser la seekBar:

    MediaPlayer mediaPlayer;
Button buttonPlayPause;
ImageView Image;
private int stateMediaPlayer;
private final int stateMP_NotStarter = 0;
private final int stateMP_Playing = 1;
private final int stateMP_Pausing = 2;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playerwere);
Image = (ImageView) findViewById(R.id.pdfview);
Image.setImageResource(R.drawable.wereim);
buttonPlayPause = (Button) findViewById(R.id.playpause);
buttonPlayPause.setOnClickListener(buttonPlayPauseOnClickListener);
initMediaPlayer();
}
private void initMediaPlayer() {
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(were.this, R.raw.were);
stateMediaPlayer = stateMP_NotStarter;
}
Button.OnClickListener buttonPlayPauseOnClickListener = new Button.OnClickListener() {
@Override
public void onClick(View v) {
//TODO Auto-generated method stub
switch (stateMediaPlayer) {
case stateMP_NotStarter:
mediaPlayer.start();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
stateMediaPlayer = stateMP_Playing;
break;
case stateMP_Playing:
mediaPlayer.pause();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_play);
stateMediaPlayer = stateMP_Pausing;
break;
case stateMP_Pausing:
mediaPlayer.start();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
stateMediaPlayer = stateMP_Playing;
break;
}
}
};

Je pense que cela peut être un travail pour vous.

Créer un thread qui va vérifier la position dans le morceau et se déplace seekbar comme ça,

private Runnable moveSeekBarThread = new Runnable() {
public void run() {
if(mediaPlayer.isplaying){
int mediaPos_new = mediaPlayer.getCurrentPosition();
int mediaMax_new = mediaPlayer.getDuration();
seekBar.setMax(mediaMax_new);
seekBar.setProgress(mediaPos_new);
handler.postDelayed(this, 100); //Looping the thread after 0.1 second
//seconds
}  
}
};

Et appeler ce thread comme celui-ci,

  mediaPos = mediaPlayer.getCurrentPosition();
mediaMax = mediaPlayer.getDuration();
seekBar.setMax(mediaMax); //Set the Maximum range of the
seekBar.setProgress(mediaPos);//set current progress to song's
handler.removeCallbacks(moveSeekBarThread);
handler.postDelayed(moveSeekBarThread, 100);

Ok, j'ai essayé, mais je ne pense pas que je l'ai mis au bon endroit, parce que maintenant lors de la lecture audio de la barre ne bouge toujours pas, mais si je déplace le seekbar l'audio ne cherchent. J'ai mis mon nouveau code dans la question d'origine
ne fonctionne probablement pas de l'interface utilisateur ne peut pas être mis à jour à partir de n'importe quel autre thread. Ajouter une interface d'une certaine sorte.
