嘗試使用由TextWatcher創建數組導致錯誤和強制關閉

全局聲明

TextView test; 
    EditText edittext; 
    TextWatcher watcher; 
    ArrayList<String> pastWrittenStrings;

的onCreate（）

....setcontentview etc... 

test = (TextView)findViewById(R.id.textView2); 
edittext = (EditText)findViewById(R.id.spokenmsg); 
pastWrittenStrings = new ArrayList<String>(); 

watcher = new TextWatcher(){ 

     @Override 
     public void afterTextChanged(Editable s) { 


     } 

     @Override 
     public void beforeTextChanged(CharSequence s, int start, int count, 
       int after) { 
     String writtenNoLowerCase = test.getText().toString(); 

     pastWrittenStrings.add(writtenNoLowerCase); 
     if(pastWrittenStrings.size()-1 != 0){ 
      edittext.setText(pastWrittenStrings.size()); //THIS LINE CAUSES THE ERROR 
     } 
     } 
     @Override 
     public void onTextChanged(CharSequence s, int start, int before, 
       int count) { 

     } 

    };

onbuttonclick（視圖V）;

test.addTextChangedListener(watcher); 
test.setText("calculations");

基本上，beforeTextChanged中的edittext行導致錯誤。我實際上試圖做的是在改變之前記錄字符串「test」的過去實例，並創建一個與它們一起的數組列表。我從來沒有設法從pastWrittenStrings中獲得任何類型的字符串，並且我嘗試了所有的東西，甚至將arraylist轉換爲數組。

請幫忙！

郵政logcat的。我想這是StackOverflowException，因爲任何這些方法中的.setText（）都會導致SOE。看到這裏：http://stackoverflow.com/questions/7222944/changing-text-in-android-on-text-change-causes-overflow-error/7222993#7222993 只是修改它爲您的需求。 –

已發佈。實際上是IllegalStateException。 –

使用

edittext.setText(String.valueOf(pastWrittenStrings.size()));

用於示出的EditText整數值，因爲setText方法接受CharSequence作爲參數，而不是整數

你是對的。對不起，問題解決了這只是一個非常被忽視的睡眠剝奪造成的錯誤 –
