用image+text ()显示suggestBox()

Question

我试图使用SuggestBox和MultiWordSuggestOracle显示图标和建议中的文本，如下代码所示：

public class Suggestions implements Suggestion {

    private String suggestion;

    public Suggestions(){}

    public Suggestions(String suggestion){
        this.suggestion = new String( suggestion );
    }
    @Override
    public String getDisplayString() {
        return ( suggestion + " <img src='/images/image.png'/> " );
    }
    @Override
    public String getReplacementString() {
        return suggestion;
    }}

在onModuleLoad函数中包含以下代码：

 MultiWordSuggestOracle oracle = new MultiWordSuggestOracle(){
          @Override
          public boolean isDisplayStringHTML() {
              return true;
          }};  
          oracle.add(new Suggestions("A").getDisplayString());
      SuggestBox suggestionBox = new SuggestBox(oracle);

问题: html代码被打印为普通文本。你们能建议一下密码有什么问题吗？

谢谢！

Answer 1

因为你的建议课从未被使用过！

多字甲骨文只有显示字符串，并创建自己的建议项。

只需重写甲骨文中的methode createSuggestion：

MultiWordSuggestOracle oracle = new MultiWordSuggestOracle(){
      @Override
      public boolean isDisplayStringHTML() {
          return true;
      }

      @Override
      protected MultiWordSuggestion createSuggestion(String replacementString, String displayString) {
         return new Suggestions(replacementString);
      }
};  
oracle.add(new Suggestions("A").getDisplayString());
SuggestBox suggestionBox = new SuggestBox(oracle);

下面是我做了什么，让image+text在建议下降。

public class Suggestions implements Suggestion {

    private String suggestion;

    public Suggestions(){}

    public Suggestions(String suggestion){
        this.suggestion = new String( suggestion );
    }
    @Override
    public String getDisplayString() {
        return ( suggestion + new Image('/images/image.png') );
    }
    @Override
    public String getReplacementString() {
        return suggestion;
    }}

OnModuleLoad function is: 

MultiWordSuggestOracle oracle = new MultiWordSuggestOracle(){
      @Override
      public boolean isDisplayStringHTML() {
          return true;
      }

      @Override
      protected MultiWordSuggestion createSuggestion(String replacementString, String displayString) {
         return new Suggestions(replacementString);
      }
};  
oracle.add("A");
SuggestBox suggestionBox = new SuggestBox(oracle);
