我可以「存儲」一個數組中的spannable字符串嗎？

Question

我有一個要求，建立一個文本視圖，其中包含類似於： 「標題[x]」後面跟着「一些文本」，後面跟着「\ n」，接着是「標題[y]」，後跟「更多文本」等。給

題名[X]一些文本

題名[Y]更多的文字

我需要題目大膽地將有不同的顏色給每一個標題。我總共有11個標題，最多可以選擇30個文本字符串，任何標題都可以有任何文本字符串。在每個週期中，我將在我的最終結果文本中包含1到6個標題。 我用x和y的「已知」值構建textView沒有問題，但在現實生活中，我不知道這些值，直到我開始構建可跨越的字符串。我不想構建每個可能的變體字符串（超過300）。 我試圖創建所有「標題」spannables並將它們追加到我的「結果」，因爲我創建它們並且它工作正常，但是如果我創建它們並在最後一個語句中添加它們，則會丟失粗體和顏色屬性。

我main.xml中有color_test的ID一個TextView。

titleIndex = 1; 

SpannableStringBuilder resultText = new SpannableStringBuilder(); 
String firstTitle = titles[titleIndex]; 
SpannableString firstTitleSpannable= new SpannableString(firstTitle);

我不是很肯定，如果我正確地理解您的問題，但如果我這樣做，我會寫一個類其中包含運行時所需的所有屬性並創建對象：

public class SpannableContent { 
    private StringBuilder result = new StringBuilder(); 
    private String title1 = null; 
    private String title2 = null; 
    private String description = null; 

    public SpannableContent(String _title1, String _title2, String _desc) { 
     this.title1 = _title1; 
     this.title2 = _title2; 
     this.description = _desc; 

     result.append(getFormatedTitle1()); 
     result.append(getFormatedTitle2()); 
     result.append(getFormatedDescription()); 
    } 

    private String getFormatedTitle1() { 
     String resString = null; 
     // do whatever Spannable stuff you want to do w/ title1 here 

     return resString; 
    } 

    private String getFormatedTitle2() { 
     String resString = null; 
     // do whatever Spannable stuff you want to do w/ title2 here 

     return resString; 
    } 

    private String getFormatedDescription() { 
     String resString = null; 
     // do whatever Spannable stuff you want to do w/ the description here 

     return resString; 
    } 

    public String getFinalContent() { 
     return result.toString(); 
    } 
} 

運行像

SpannableContent spannableC = new SpannableContent(dynamicTitle1, dynamicTitle2, dynamicDesc); 
resultText.append(spannableC.getFinalContent()); 

您可以在對象存儲在類型SpannableContent的ArrayList中然後做。

ArrayList<SpannableContent> spannableArrayList = new ArrayList<SpannableContent>();
