安卓：每行10個字符限制的TextView

Question

我從EditText上讀值，並將其寫入TextView的

editTitle1.addTextChangedListener(new TextWatcher() { 
       public void afterTextChanged(Editable s) { 
       } 

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

       public void onTextChanged(CharSequence s, int start, int before, int count) { 
        s = editTitle1.getText().toString(); 
        textTitle1.setText(s); 

       } 
      }); 

而且我想，在一個線 - 最多10個字符，因此，如果所有的20個字符 - 它的兩個線路在TextView中，每行10個字符。我如何做到這一點？ 我嘗試的android：最大長度=「10」，但它並不能幫助

Answer 1

定義返回格式化後，將每行10個字符的字符串的方法：

public String getTenCharPerLineString(String text){ 

    String tenCharPerLineString = ""; 
    while (text.length() > 10) { 

     String buffer = text.substring(0, 10); 
     tenCharPerLineString = tenCharPerLineString + buffer + "/n"; 
     text = text.substring(10); 
    } 

    tenCharPerLineString = tenCharPerLineString + text.substring(0); 
    return tenCharPerLineString; 
} 

Answer 2

添加下列2個屬性TextView的定義：

android:singleLine="false" 
android:maxems="10" 

Answer 3

我編輯通過ramaral給出了答案，他用錯了轉義序列

public String getTenCharPerLineString(String text){ 

    String tenCharPerLineString = ""; 
    while (text.length() > 10) { 

     String buffer = text.substring(0, 10); 
     tenCharPerLineString = tenCharPerLineString + buffer + "\n"; 
     text = text.substring(10); 
    } 

    tenCharPerLineString = tenCharPerLineString + text.substring(0); 
    return tenCharPerLineString; 
}
