语法高亮显示textview显示源代码而不是换行

Question

我必须在文本视图中显示一些源代码以及语法高亮显示 所以我使用了java prettify jar并将其导入我的项目并且开始了一个美化的荧光笔课程 突出显示工作正常，但代码之间没有插入新行

喜欢这个

我的代码

的strings.xml

<?xml version="1.0" encoding="utf-8"?>

<string name="app_name">syntaxtest</string>
<string name="javacode">
    public class MainActivity extends Activity 
    {
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    TextView tv = (TextView) findViewById(R.id.mainTextView);

    }
    }</string>

mainactivity.java

public class MainActivity extends Activity 
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    String code = getResources().getString(R.string.javacode);

    TextView tv = (TextView) findViewById(R.id.mainTextView);

    // code is a String with source code to highlight
     // myTextView is a TextView component
    PrettifyHighlighter highlighter = new PrettifyHighlighter();
    String highlighted = highlighter.highlight("java", code);
    tv.setText(Html.fromHtml(highlighted));

}
}

美化高级课程

public class PrettifyHighlighter {
private static final Map<String, String> COLORS = buildColorsMap();

private static final String FONT_PATTERN = "<font color=\"#%s\">%s</font>";

private final Parser parser = new PrettifyParser();

public String highlight(String fileExtension, String sourceCode) {
    StringBuilder highlighted = new StringBuilder();
    List<ParseResult> results = parser.parse(fileExtension, sourceCode);
    for(ParseResult result : results){
        String type = result.getStyleKeys().get(0);
        String content = sourceCode.substring(result.getOffset(), result.getOffset() + result.getLength());
        highlighted.append(String.format(FONT_PATTERN, getColor(type), content));
    }
    return highlighted.toString();
}

private String getColor(String type){
    return COLORS.containsKey(type) ? COLORS.get(type) : COLORS.get("pln");
}

private static Map<String, String> buildColorsMap() {
    Map<String, String> map = new HashMap<>();
    map.put("typ", "87cefa");
    map.put("kwd", "00ff00");
    map.put("lit", "ffff00");
    map.put("com", "999999");
    map.put("str", "ff4500");
    map.put("pun", "eeeeee");
    map.put("pln", "ffffff");
    return map;
}
  }

尝试使用以下内容但没有任何效果

 / n <br > <br \> , <![CDATA[ ... ]]>

这是我尝试的方式

    <string name="javacode">
    <![CDATA[

        super.onCreate(savedInstanceState);<br \>
    setContentView(R.layout.main);<br>
    String code = getResources().getString(R.string.javacode);<br />
    <br />
    TextView tv = (TextView) findViewById(R.id.mainTextView);<br />

        ]]>

</string>

我该怎么办？ 帮我 提前致谢
