I needed help with this but didn't really find clear instructions. How to create a button that will fast forward and rewind current song on hold.
private Handler repeatUpdateHandler = new Handler();
public int mValue; //increment
private boolean mAutoIncrement = false; //for fast foward in real time
private boolean mAutoDecrement = false; // for rewind in real time
private class RptUpdater implements Runnable {
public void run() {
if( mAutoIncrement ){
mValue += 30; //change this value to control how much to forward
mediaPlayer.seekTo(getCurrentPosition()+ mValue);
repeatUpdateHandler.postDelayed( new RptUpdater(), 50 );
} else if( mAutoDecrement ){
mValue -= 30; //change this value to control how much to rewind
seekTo(getCurrentPosition()- mValue);
repeatUpdateHandler.postDelayed( new RptUpdater(), 50 );
}
}
}
btnPrev.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
v.setPressed(true);
mAutoDecrement = true;
repeatUpdateHandler.post( new RptUpdater() );
return false;
}
else if(event.getAction() == MotionEvent.ACTION_UP) {
v.setPressed(false);
if( (event.getAction()==MotionEvent.ACTION_UP || event.getAction()==MotionEvent.ACTION_CANCEL)
&& mAutoDecrement ){
mAutoDecrement = false;
}
return false;
}
return false;
}
});
btnNext.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
v.setPressed(true);
mAutoIncrement = true;
repeatUpdateHandler.post( new RptUpdater() );
return false;
}
else if(event.getAction() == MotionEvent.ACTION_UP) {
v.setPressed(false);
if( (event.getAction()==MotionEvent.ACTION_UP || event.getAction()==MotionEvent.ACTION_CANCEL)
&& mAutoIncrement ){
mAutoIncrement = false;
}
return false;
}
return false;
}
});
