Change SeekBar and time text output

Rewind seekbar works, that is, I touch seakbar and move to the desired position and acc. the sound is rewound, but for some reason there is no refresh of the everykbara every second, although the handler is hung

@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); fab(); pageNumber = getArguments().getInt(ARGUMENT_PAGE_NUMBER); //нахожу в xml seekBar = (SeekBar) getActivity().findViewById(R.id.sbar); playerText = (TextView) getActivity().findViewById(R.id.textPlayer); anim = AnimationUtils.loadAnimation(getContext(), R.anim.clickbutton); potehanim = AnimationUtils.loadAnimation(getContext(), R.anim.potehkianim); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment, container, false); //присваиваю обработчик плееру mediaPlayer = new MediaPlayer(); mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { @Override public void onPrepared(MediaPlayer mp) { mediaPlayer.start(); } }); //у меня есть массив мелодий и на каждый case своя мелодия по нажатию на который воспр. мелодия+анимация for (int i = 0; i < fragments.length; i++) { arr_imageA[i] = (ImageView) rootView.findViewById(fragments[i]); arr_imageA[i].setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { v.startAnimation(potehanim); switch (v.getId()) { case R.id.imageView1: startActivity(getActivity(), a1.class); break; case R.id.imageView2: startActivity(getActivity(), a2.class); break; case R.id.imageView3: startActivity(getActivity(), a3.class); break; } } }); if (pageNumber == 1) { rootViewB = inflater.inflate(R.layout.fragment2, container, false); for (int index = 0; index < buttonIds.length; index++) { arr_imageB[index] = (ImageView) rootViewB.findViewById(buttonIds[index]); } for (int j = 0; j < arr_imageB.length; j++) { arr_imageB[j].setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { stopAnimation(); switch (v.getId()) { case R.id.b1: { v.startAnimation(anim); playSample(soundsRawResIds[0]); break; } case R.id.b2: { v.startAnimation(anim); playSample(soundsRawResIds[1]); break; } case R.id.b3: { v.startAnimation(anim); playSample(soundsRawResIds[2]); break; } case R.id.b4: { v.startAnimation(anim); playSample(soundsRawResIds[3]); break; } case R.id.b5: { v.startAnimation(anim); playSample(soundsRawResIds[4]); break; } case R.id.b6: { v.startAnimation(anim); playSample(soundsRawResIds[5]); break; } case R.id.b7: { v.startAnimation(anim); playSample(soundsRawResIds[6]); break; } } } }); } return rootViewB; } } return rootView; } //запуск активити с задержкой public void startActivity(final Context activityContext, final Class<? extends Activity> activityClass) { new Handler().postDelayed(new Runnable() { @Override public void run() { startActivity(new Intent(activityContext, activityClass)); } }, 200); } 

// method in which I launch the player

 private void playSample(int resid) { AssetFileDescriptor afd = getContext().getResources().openRawResourceFd(resid); if (mediaPlayer.isPlaying()) { mediaPlayer.stop(); stopAnimation(); } else { try { mediaPlayer.reset(); mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength()); mediaPlayer.prepareAsync(); afd.close(); } catch (IllegalArgumentException e) { Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e); } catch (IllegalStateException e) { Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e); } catch (IOException e) { Log.e(TAG, "Unable to play audio queue do to exception: " + e.getMessage(), e); } } }
