將語句設置爲switch語句中的edittext的錯誤

我正在嘗試爲edittext使用settext。我有這個代碼，因爲我需要在多個edittext中使用afterTextChanged（）。如果我在案例中使用setText：應用程序崩潰，但它在一個按鈕的onClick外部正常工作。將語句設置爲switch語句中的edittext的錯誤

public Button btn; 
    public EditText et1, et2, et3; 
    private int whoHasFocus = 0; 

    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.testing2, container, false); 

     super.onCreate(savedInstanceState); 

     et1 = (EditText) view.findViewById(R.id.ladoA); 
     et1.setOnFocusChangeListener(this); 
     et1.addTextChangedListener(this); 
     et2 = (EditText) view.findViewById(R.id.ladoB); 
     et2.setOnFocusChangeListener(this); 
     et2.addTextChangedListener(this); 
     et3 = (EditText) view.findViewById(R.id.ladoC); 
     et3.setOnFocusChangeListener(this); 
     et3.addTextChangedListener(this); 

     btn = (Button) view.findViewById(R.id.button); 
     btn.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View view) { 
       et1.setText("Works correctly."); 
      } 
     }); 

     return view; 
    } 

    @Override 
    public void beforeTextChanged(CharSequence s, int start, int count, int after) { 

    } 

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

    } 

    @Override 
    public void afterTextChanged(Editable s) { 
     switch (whoHasFocus) { 
      case 1: 
       et2.setText("It does not work."); 
       break; 
      case 2: 

       break; 
      case 3: 

       break; 
     } 
    } 

    @Override 
    public void onFocusChange(View v, boolean hasFocus) { 
     switch (v.getId()) { 
      case R.id.ladoA: 
       whoHasFocus = 1; 
       break; 
      case R.id.ladoB: 
       whoHasFocus = 2; 
       break; 
      case R.id.ladoC: 
       whoHasFocus = 3; 
       break; 
     } 
    } 


}

請在應用程序崩潰時發佈輸出到Logcat的錯誤。 –

@AndrewBrooke泰克斯回答，我張貼在另一個答案。 –

您應該將其編輯到原始文章中，而不是創建答案 –

您正在設置afterTextChanged中的文本，這會導致再次調用相同的方法，導致無限循環。刪除偵聽器，設置文本，然後添加偵聽器。

et2.removeTextChangedListener(this); 
et2.setText("this will work"); 
et2.addTextChangedListener(this);

呼叫的setText OnTextChanged導致無限循環.. 您可以設置條件來阻止它：

if (et2.getText.equals(originalValue)) { 
    // do nothing 
} else { 
    et2.setText("xxx"); 
    originalValue = et2.getText(); 
}

您設置的EditText文本里面afterTextChanged，它再次調用afterTextChanged。這個遞歸調用創建了導致堆棧溢出的無限循環。
