EditText與驗證TextWatcher重複Android

Question

我有一個EditText與面具「## - ###。###」和結果是11-111.111，所以我決定使用TextWatch，所以我做了..

cepFrom.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) { 
      if(s.length() == 10){ 
       //getCepFrom(s.toString()); 
       Toast.makeText(DetalhesProdutos.this, "OK", Toast.LENGTH_SHORT).show(); 
      } 
     } 

     @Override 
     public void afterTextChanged(Editable s) { 

     } 
    }); 

這將消耗一個WebService，但只是爲了測試，敬酒與OK消息，執行兩次，我不」知道爲什麼...

    } 

    @Override 
    public void onTextChanged(CharSequence s, int start, int before, int count) { 

    } 

    @Override 
    public void afterTextChanged(Editable s) { 
    if(cepFrom.getText().length() == 10){ 
      //getCepFrom(s.toString()); 
      Toast.makeText(DetalhesProdutos.this, "OK", Toast.LENGTH_SHORT).show(); 
     } 
    } 
});
