如何防止URL被包装在TextView中？

Question

我有一个多行TextView它可以显示一些可选的URL。现在我有一个问题：我的一些很长的URL显示的包裹在://

sometext sometext http:// <-- AUTO LINE WRAP 
google.com/ 

如何禁用包裹整个URL或至少http(s)://前缀的位置？不过，我仍然需要启用文字环绕功能。

我的文字换行这样的

sometext sometext <-- AUTO LINE WRAP 
http://google.com/

这是为了实现自定义的包装概念TextView的恰恰证明。 您可能需要根据您的要求添加/编辑条件。

如果您的要求是，我们的textview类必须以这样的方式显示多行，以至于它不应该以某些文本结束（这里是http：//和http :)， 我修改了非常流行的textview类的代码在SO满足这一要求： 来源： Auto Scale TextView Text to Fit within Bounds

变化：

private boolean mCustomLineWrap = true; 

/** 
    * Resize the text size with specified width and height 
    * @param width 
    * @param height 
    */ 
    public void resizeText(int width, int height) { 
     CharSequence text = getText(); 
     // Do not resize if the view does not have dimensions or there is no text 
     if(text == null || text.length() == 0 || height <= 0 || width <= 0 || mTextSize == 0) { 
      return; 
     } 

     // Get the text view's paint object 
     TextPaint textPaint = getPaint(); 

     // Store the current text size 
     float oldTextSize = textPaint.getTextSize(); 
     // If there is a max text size set, use the lesser of that and the default text size 
     float targetTextSize = mMaxTextSize > 0 ? Math.min(mTextSize, mMaxTextSize) : mTextSize; 

     // Get the required text height 
     int textHeight = getTextHeight(text, textPaint, width, targetTextSize); 

     // Until we either fit within our text view or we had reached our min text size, incrementally try smaller sizes 
     while(textHeight > height && targetTextSize > mMinTextSize) { 
      targetTextSize = Math.max(targetTextSize - 2, mMinTextSize); 
      textHeight = getTextHeight(text, textPaint, width, targetTextSize); 
     } 



     if(mCustomLineWrap) { 

      // Draw using a static layout 
      StaticLayout layout = new StaticLayout(text, textPaint, width, Alignment.ALIGN_NORMAL, mSpacingMult, mSpacingAdd, false); 
      // Check that we have a least one line of rendered text 
      if(layout.getLineCount() > 0) { 
       String lineText[] = new String[layout.getLineCount()]; 
       // Since the line at the specific vertical position would be cut off, 
       // we must trim up to the previous line 
       String wrapStr = "http:", wrapStrWithSlash = "http://"; 
       boolean preAppendWrapStr = false, preAppendWrapStrWithSlash = false ; 
       for(int lastLine = 0; lastLine < layout.getLineCount(); lastLine++) 
       { 
        int start = layout.getLineStart(lastLine); 
        int end = layout.getLineEnd(lastLine); 
        lineText[lastLine] = ((String) getText()).substring(start,end); 
        if(preAppendWrapStr) 
        { 
         lineText[lastLine] = "\n" + wrapStr + lineText[lastLine]; 
         preAppendWrapStr = false; 
        } 
        else if(preAppendWrapStrWithSlash) 
        { 
         lineText[lastLine] = "\n" + wrapStrWithSlash + lineText[lastLine]; 
         preAppendWrapStrWithSlash = false; 
        } 

        if(lineText[lastLine].endsWith(wrapStr)) 
        { 
         preAppendWrapStr = true; 
         lineText[lastLine] = lineText[lastLine].substring(0,lineText[lastLine].lastIndexOf(wrapStr)); 
        } 
        if(lineText[lastLine].endsWith(wrapStrWithSlash)) 
        { 
         preAppendWrapStrWithSlash = true; 
         lineText[lastLine] = lineText[lastLine].substring(0,lineText[lastLine].lastIndexOf(wrapStrWithSlash)); 
        } 

       } 
       String compString = ""; 
       for(String lineStr : lineText) 
       { 
        compString += lineStr; 
       } 
        setText(compString); 
      } 

     } 

     // Some devices try to auto adjust line spacing, so force default line spacing 
     // and invalidate the layout as a side effect 
     textPaint.setTextSize(targetTextSize); 
     setLineSpacing(mSpacingAdd, mSpacingMult); 

     // Notify the listener if registered 
     if(mTextResizeListener != null) { 
      mTextResizeListener.onTextResize(this, oldTextSize, targetTextSize); 
     } 

     // Reset force resize flag 
     mNeedsResize = false; 
    }
