如何處理多個EditTexts的單個TextWatcher事件？

Question

我在三個不同的過濾器的視圖佈局中使用了三個EditText小部件。如果我輸入其中一個，不應該有另一個EditTexts爲空？

下面是我的片段：

public class Fragment_Assigned extends Fragment { 
    public EditText et_first; 
    public EditText et_second; 
    public EditText et_third; 

    private ArrayList<obj> list_first; 
    private ArrayList<obj> list_second; 
    private ArrayList<obj> list_third; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     et_first = (EditText) v.findViewById(R.id.et_first); 
     et_second = (EditText) v.findViewById(R.id.et_second); 
     et_third = (EditText) v.findViewById(R.id.et_third); 

     listoffline = //getFrom DataBase 
     filterListCustomer = listoffline; 
     filterListModel = listoffline; 
     filterListCompany = listoffline; 

     et_first.addTextChangedListener(new GenericTextWatcher(et_first)); 
     et_second.addTextChangedListener(new GenericTextWatcher(et_second)); 
     et_third.addTextChangedListener(new GenericTextWatcher(et_third)); 
    } 
} 

GenericTextWatcher方法：

private class GenericTextWatcher implements TextWatcher { 
    private View view; 

    private GenericTextWatcher(View view) { 
     this.view = view; 
    } 

    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { 
    } 

    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) { 
    } 

    public void afterTextChanged(Editable editable) { 
     String text = editable.toString(); 
     switch (view.getId()) { 
      case R.id.et_first: 
       //someMethod; 
       break; 
      case R.id.et_second: 
       //someMethod; 
       break; 
      case R.id.et_third: 
       //someMethod; 
       break; 
     } 
    } 
} 

當我運行這個和類型的EditText然後logcat中看起來像這樣莫名其妙：

null您的剩餘editText焦點變化

et_first.setOnFocusChangeListener(new View.OnFocusChangeListener() { 
     @Override 
     public void onFocusChange(View v, boolean hasFocus) { 
      et_second.setText(""); 
      et_third.setText(""); 
     } 
    }); 

    et_second.setOnFocusChangeListener(new View.OnFocusChangeListener() { 
     @Override 
     public void onFocusChange(View v, boolean hasFocus) { 
      et_first.setText(""); 
      et_third.setText(""); 
     } 
    }); 

    et_third.setOnFocusChangeListener(new View.OnFocusChangeListener() { 
     @Override 
     public void onFocusChange(View v, boolean hasFocus) { 
      et_second.setText(""); 
      et_first.setText(""); 
     } 
    });
