无法从字符串中正确显示卢比符号.xml

Question

这样就可以了:

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>

我不明白为什么它会这样做，它看起来是一样的…!

Answer 1

您不应该将字符串与字符串资源连接，您可以使用占位符:

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

和使用:

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

Answer 2

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);
