Fehler bei der SeekBar/EditText-Integration

Question

Ich stehe vor einem Problem, wenn ich versuche, EditText mit der Seekbar und umgekehrt anzupassen. Wenn ich meine Suchleiste mit dem Mindestwert = 0 beginne, funktioniert es perfekt. Aber wenn ich den Mindestwert ändern, funktioniert es nicht! Kann mir bitte jemand helfen?

private void bindElements(){ 
    final int SEEKBAR_SIZE_CORRECTION = 200; 
    final int SEEKBAR_MAX_SIZE = 1000; 
    // 10000 Change to object max value 
    int correctMax = SEEKBAR_MAX_SIZE - SEEKBAR_SIZE_CORRECTION; 


    mEtValue = (EditText) findViewById(R.id.et_value); 
    mEtValue.setFilters(new InputFilter[] { new InputFilter.LengthFilter(SEEKBAR_MAX_SIZE) }); 
    mEtValue.addTextChangedListener(new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, int count, int after) { 
     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, int before, int count) { 
      //3 is the length of SEEKBAR_SIZE_CORRECTION (2 0 0) 
      if (s.toString().length() == 3) { 
       //200 is the text of SEEKBAR_SIZE_CORRECTION 
       s = new SpannableStringBuilder("200"); 
      } 
      mSbValue.setProgress(Integer.parseInt(String.valueOf(s))); 
     } 

     @Override 
     public void afterTextChanged(Editable s) { 
     } 
    });[![enter image description here][1]][1] 

    mSbValue = (SeekBar) findViewById(R.id.sb_value); 
    mSbValue.setMax(correctMax); 
    mSbValue.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { 

     @Override 
     public void onStopTrackingTouch(SeekBar seekBar) { 
     } 

     @Override 
     public void onStartTrackingTouch(SeekBar seekBar) { 
     } 

     @Override 
     public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { 
      progress += SEEKBAR_SIZE_CORRECTION; 
      if (mEtValue != null) { 
       mEtValue.setText(String.valueOf(progress)); 
       mEtValue.setSelection(mEtValue.getText().length()); 
      } 
     } 
    }); 
} 

Vielen Dank!

Aktualisierter Code, der für Seekbar Drag funktioniert.

private void bindElements(){ 

    final int SEEKBAR_SIZE_CORRECTION = 200; 
    final int SEEKBAR_MAX_SIZE = 1000; 
    // 10000 Change to object max value 
    int correctMax = SEEKBAR_MAX_SIZE - SEEKBAR_SIZE_CORRECTION; 


    mEtValue = (EditText) findViewById(R.id.et_value); 
    mEtValue.setFilters(new InputFilter[] { new InputFilter.LengthFilter(SEEKBAR_MAX_SIZE) }); 
    mEtValue.addTextChangedListener(new TextWatcher() {
