how are you supposed to let the mediaplayer know what it is supposed to play?
wholeTextPlayer = MediaPlayer.create(Lesson1Reading.this, engAu);
It works fine if I declare the file in the top:
MediaPlayer wholeTextPlayer;
private int engAu = R.raw.l1r_en_l10;
Button btn_default_acc_whole;
It doesn't work from within a button click if / else statement wherever I try to put it with the following combination:
MediaPlayer wholeTextPlayer;
private int engAu;
Button btn_default_acc_whole;
The button click:
final Button btn_default_acc_whole = (Button) findViewById(R.id.btn_default_acc_whole);
btn_default_acc_whole.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
if (wholeTextPlayer.isPlaying()) {
wholeTextPlayer.pause();
} else {
wholeTextPlayer.start();
startPlayProgressUpdater();
}
setEngAu(R.raw.l1r_en_l10); //this line doesn't want to fit anywhere
}
});
The setter:
public void setEngAu(int engAu) {
this.engAu = engAu;
}
Of course they are separately placed in the activity, I just copied and pasted the relevant bits from it.
Thanks guys.
Here is the whole code:
'public class Lesson1Grammar extends Activity {
private SeekBar seekBar;
MediaPlayer wholeTextPlayer;
private int engAu;
private final Handler handler = new Handler();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.lesson1grammar);
WholeDefAccPlayer();
final RelativeLayout playerScreen = (RelativeLayout)findViewById(R.id.playerScreen);
final ImageButton btn_player_screen = (ImageButton) findViewById(R.id.btn_player_screen);
btn_player_screen.setOnClickListener(new View.OnClickListener() {
//this hides/unhides the part of the layout in which the player is
@Override
public void onClick(View arg0) {
if (playerScreen.isShown()) {
playerScreen.setVisibility(View.GONE);
} else {
playerScreen.setVisibility(View.VISIBLE);
}
}
});
final Button btn_default_acc_whole = (Button) findViewById(R.id.btn_default_acc_whole);
btn_default_acc_whole.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
if (wholeTextPlayer.isPlaying()) {
wholeTextPlayer.pause();
} else {
setEngAu(R.raw.default_acc_audio);
wholeTextPlayer.start();
startPlayProgressUpdater();
}
}
});
}
public void setEngAu(int engAu) {
this.engAu = engAu;
}
private void WholeDefAccPlayer() {
wholeTextPlayer = MediaPlayer.create(Lesson1Grammar.this, engAu);
((TextView) findViewById(R.id.getTitleOfAccent)).setText(R.string.btn_lesson1reading);
seekBar = (SeekBar) findViewById(R.id.seekBar);
seekBar.setMax(wholeTextPlayer.getDuration());
seekBar.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
seekChange(v);
return false;
}
});
}
public void startPlayProgressUpdater() {
seekBar.setProgress(wholeTextPlayer.getCurrentPosition());
if (wholeTextPlayer.isPlaying()) {
Runnable notification = new Runnable() {
public void run() {
startPlayProgressUpdater();
}
};
handler.postDelayed(notification, 1000);
}
else wholeTextPlayer.pause();
}
// This is event handler thumb moving event
private void seekChange(View v){
if(wholeTextPlayer.isPlaying()){
SeekBar sb = (SeekBar)v;
wholeTextPlayer.seekTo(sb.getProgress());
}
}
} '
if your plan is to make the method setEngAu() is the controller as you mentioned in the comment. then you you need to use that method like this
public void setEngAu(int enAu)
{
this.EngAu = enAu;
wholeTextPlayer.setDataSource(engAu);
wholeTextPlayer.prepare();
}
you need to implement onPrepared listener from the media player I do not know your classes but I assume where you say something like;
wholeTextPlayer = new MediaPlayer();
wholeTextPlayer.setOnPreparedListener(this);
here you start the player after it became prepared
public void onPrepared(MediaPlayer player)
{
player.start();
}
Remember to you will need to call wholeTextPlayer.release()
if you do not want the player to hold on that resource anymore( think of it as memory issues - recommended if you check the documentation)
EDIT : I adjusted your code a little, please take a look and let me know.
