在每个新行的开头的EditText

Question

我想获得通过的EditText用户的文本INOUT添加文本，所以我得到了新的文本和检测的新线，但我想在开始时添加文本每一个新的line..How做呢？

Ibold.addTextChangedListener(new TextWatcher(){ 
        @Override 
        public void onTextChanged(CharSequence txt, int start, int before, int count) { 
         if (-1 != bold.indexOf("\n")){ 


          //here I detected new line 


         } 
        }

你可以试试这个：

Ibold.addTextChangedListener(new TextWatcher(){ 
       @Override 
       public void onTextChanged(CharSequence txt, int start, int before, int count) { 
        if (-1 != bold.indexOf("\n")){ 


         //here I detected new line 
         String editTextContent = Ibold.getText().toString(); 
         editTextContent += "ADD YOUR TEXT HERE, IT WILL BE INSERTED AFTER THE LAST LINE BREAK"; 
         Ibold.setText(editTextContent); 


        } 
       }
