EditText在第一次輸入後停留在鍵盤後

Question

有兩個EditText，如果用戶在第一個字符中輸入四個字符，焦點會自動轉到另一個EditText。當用戶在第二個EditText中輸入第一個字符時，滾動中斷並且第二個編輯文本開始留在鍵盤後面。

另外，當用戶專注於第二個EditText時，它仍然留在鍵盤後面。如果用戶首先關注第一個EditText，然後關閉鍵盤並關注第二個EditText，則滾動工作完美。

這個問題只發生在三星Galaxy Grand Prime（Android 4.4.4版本）。

你能幫助這種奇怪的行爲嗎？

MyActivity.java

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    //..... 

    txtNewPin.setFocusable(true); 
    txtNewPin2.setFocusable(true); 
    txtNewPin.requestFocus(); 

    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); 
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); 

    txtNewPin.addTextChangedListener(getTextChangedListener_txtNewPin()); 
    txtNewPin2.addTextChangedListener(getTextChangedListener_txtNewPin2()); 

    //..... 
} 

private TextWatcher getTextChangedListener_txtNewPin() { 
    return new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, int before, int count) { 

     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, int before, int count) { 
      if (s.length() == 4) { 
       txtNewPin.clearFocus(); 
       txtNewPin2.requestFocus(); 
      } 
     } 

     @Override 
     public void afterTextChanged(Editable editable) { 

     } 
    }; 
} 

private TextWatcher getTextChangedListener_txtNewPin2() { 
    return new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, int before, int count) { 

     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, int before, int count) { 
      if (s.length() == 4) { 
       kart_sifre_degistir_button.performClick(); 
      } 
     } 

     @Override 
     public void afterTextChanged(Editable editable) { 

     } 
    }; 
} 

MyActivity XML

第一的EditText ID：yeni_sifre_bir
二的EditText ID：yeni_sifre_iki
三的EditText ID：textview_editText_search（這個完美的作品！）

我意識到這個問題是由於失去在第二的EditText輸入一個字符後的焦點。它突然失去了焦點！

解決。我已經改變了佈局MyActivity.xml如下（使用滾動型和RelativeLayout的代替的LinearLayout）

<?xml version="1.0" encoding="utf-8"?>

Answer 2

嘗試afterTextChanged

private TextWatcher getTextChangedListener_txtNewPin() { 
return new TextWatcher() { 
    @Override 
    public void beforeTextChanged(CharSequence s, int start, int before, int count) { 

    } 

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

    } 

    @Override 
    public void afterTextChanged(Editable editable) { 
     if (editable.length() == 4) { 
      txtNewPin.clearFocus(); 
      txtNewPin2.requestFocus(); 
     } 
    } 
}; 

}
