strings.xml 无法让卢比符号正确显示

Question

所以这很好用：

strFoo = "\u20B9" + strBar

但这不是

strFoo = R.string.rupee_symbol.toString() + strBar  //.toString() is required

//R.string.rupee_symbol.toString() evaluates to some random number 2131755148... which I believe is a character array...

strings.xml

<string name="rupee_symbol">\u20B9 </string>

我不明白为什么会这样，看起来是一样的...！

Answer 1

您不应将字符串与字符串资源连接起来，您可以使用占位符：

<string name="rupee_symbol">\u20B9%s</string>

并使用：

strFoo = resources.getString(R.string.rupee_symbol, strBar)

Answer 2

使用getString(R.string.rupee_symbol)代替R.string.rupee_symbol.toString()

For example- 
String strBar = String.valueOf(100);
    String strFoo = getString(R.string.rupee_symbol)+strBar;
    textView.setText( strFoo);
