我有这个字符串:
String[] text = {"Address 1: Street nr.45 ",
"Address 2: Street nr.67",
"Address 3: Street nr. 56 \n Phone number: 000000000"};
稍后将使用:
((TextView)findViewById(R.id.adresa)).setText(text[newSelectedAddress]);
从微调器中选择项目时。
如何在字符串内的文本中添加格式?我希望地址与大胆,街道nr。用斜体

你必须使用Spannable
。虽然创造它们有点罗嗦并且看起来很复杂,但它并不是火箭科学。
一个例子:
String source = "This is example text";
SpannedString out = new SpannedString(source);
StyleSpan boldSpan = new StyleSpan(Typeface.BOLD);
StyleSpan boldSpan2 = new StyleSpan(Typeface.BOLD);
out.setSpan(boldSpan, 1, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
out.setSpan(boldSpan2, 9, 12, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
结果:T hi s是e xam 文本
然后setText
这个Spannable而不是普通的String。

我喜欢这样亲爱的朋友:
String[] text = {"Address 1: Street nr.45 ",
"Address 2: Street nr.67",
"Address 3: Street nr. 56 \n Phone number: 000000000"};
String tempString = text[newSelectedAddress];
CharSequence charSeq= new SpannedString(tempString);
Spannable spannable = (Spannable) charSeq;
StyleSpan boldSpan = new StyleSpan(Typeface.BOLD);
StyleSpan boldSpan2 = new StyleSpan(Typeface.ITALIC);
spannable.setSpan(boldSpan, 0, "Address".length()-1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
spannable.setSpan(boldSpan2, tempString.indexOf("Street"), tempString.indexOf("Street")-1 +"Street".length()-1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
((TextView)findViewById(R.id.adresa)).setText(spannable);

有一些hack允许字符串识别html的粗体和斜体格式。将这样的内容添加到strings.xml:
<string name="address"><![CDATA[<b>Address %1$s</b>: <i>Street nr. %2$s </i>]]></string>
然后:
Resources res = getResources();
formattedString = res.getString(R.string.address, "1", "45");
// equivalent to String.format(res.getString(R.string.address), "1", "45")
Spannable s = Html.from Html(formattedString);
textView.setText(s);
