字符串数组文本格式 [英] String array text formatting

问题描述

  String [] text = {Address 1：Street nr.45，
Address 2：Street nr.67，
Address 3：Street nr。56 \\\
电话号码：[phone]}; 
  

以后会用到：

<$ p （（TextView）findViewById（R.id.adresa））。setText（text [newSelectedAddress]）;

当从微调器中选择一个项目时。

如何添加格式到字符串中的文本？我想要地址与大胆，街道号码。与斜体

解决方案

您必须使用 Spannable s。虽然创造它们有点罗嗦，看起来很复杂，但这不是火箭科学。
一个例子：

  String source =This is example text; 
 SpannedString out = new SpannedString（source）; 
 StyleSpan boldSpan =新StyleSpan（Typeface.BOLD）; 
 StyleSpan boldSpan2 =新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 是e xam ple text

然后你 setText 这个Spannable而不是普通的String。

I have this String:

    String[] text = {"Address 1: Street nr.45 ",
         "Address 2: Street nr.67",
         "Address 3: Street nr. 56 \n Phone number: 000000000"};

Which gets used later by:

        ((TextView)findViewById(R.id.adresa)).setText(text[newSelectedAddress]);

when selecting an item from a spinner.

How can I add formatting to the text inside the string?? I want Address to be with bold, Street nr. with Italic

解决方案

You have to use Spannables. Although creating them is a bit wordy and seems complex, it isn't rocket science. An example:

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);

Result: This is example text

You then setText this Spannable instead of the normal String.
