エスプレッソを使用してclickablespanをクリックするには？

Question

複数のクリック可能なスパンを含むテキストビューがあります。これらのスパンをクリックしてテストできるようにしたい。

カスタムViewActionを設定して、TextViewでclickablespansを見つけて、そのテキストを目的のテキストと突き合わせてから、そのテキストのxy座標をクリックしようとしました。しかし、TextViewに追加されたスパンはClickableSpan型ではなく、そのスパンを追加したフラグメントです。

したがって、リンクスパンを区別できません。これを行うより良い方法はありますか？

追加スパン：

@Override 
     public void perform(UiController uiController, View view) { 
      uiController.loopMainThreadUntilIdle(); 
      if (view instanceof TextView) { 

       TextView textView = (TextView) view; 
       Layout textViewLayout = textView.getLayout(); 


       SpannableString fullSpannable = new SpannableString(textView.getText()); 

       Object[] spans = fullSpannable.getSpans(0, fullSpannable.length(), Object.class); 

       ClickableSpan span = null; 
       for (Object object : spans) { 
        if (object instanceof BaseFragment) { 
         ClickableSpan foundSpan = (ClickableSpan)object; 
         int spanStart = fullSpannable.getSpanStart(foundSpan); 
         int spanEnd = fullSpannable.getSpanEnd(foundSpan); 
         if (fullSpannable.subSequence(spanStart, spanEnd).equals(aSubstring)) { 
          //Found the correct span! 
          span = foundSpan; 
         } 
        } 
       } ... go on to click the xy-coordinates

これは私のソリューションです。座標を見つける必要がないのでシンプルです。我々はClickableSpanが見つかったら、我々はそれをクリックしてください：

public static ViewAction clickClickableSpan(final CharSequence textToClick) { 
    return new ViewAction() { 
     @Override 
     public Matcher<View> getConstraints() { 
      return Matchers.instanceOf(TextView.class); 
     } 

     @Override 
     public String getDescription() { 
      return "clicking on a ClickableSpan"; 
     } 

     @Override 
     public void perform(UiController uiController, View view) { 
      TextView textView = (TextView) view; 
      SpannableString spannableString = (SpannableString) textView.getText(); 

      if (spannableString.length() == 0) { 
       // TextView is empty, nothing to do 
       throw new NoMatchingViewException.Builder() 
         .includeViewHierarchy(true) 
         .withRootView(textView) 
         .build(); 
      } 

      // Get the links inside the TextView and check if we find textToClick 
      ClickableSpan[] spans = spannableString.getSpans(0, spannableString.length(), ClickableSpan.class); 
      if (spans.length > 0) { 
       ClickableSpan spanCandidate; 
       for (ClickableSpan span : spans) { 
        spanCandidate = span; 
        int start = spannableString.getSpanStart(spanCandidate); 
        int end = spannableString.getSpanEnd(spanCandidate); 
        CharSequence sequence = spannableString.subSequence(start, end); 
        if (textToClick.toString().equals(sequence.toString())) { 
         span.onClick(textView); 
         return; 
        } 
       } 
      } 

      // textToClick not found in TextView 
      throw new NoMatchingViewException.Builder() 
        .includeViewHierarchy(true) 
        .withRootView(textView) 
        .build(); 

     } 
    }; 
} 

今、あなたはちょうどそのよう私たちのカスタムViewActionを使用することができます。

onView(withId(R.id.myTextView)).perform(clickClickableSpan("myLink"));

これは私の作品：

/** 
* Clicks the first ClickableSpan in the TextView 
*/ 
public static ViewAction clickFirstClickableSpan() { 
    return new GeneralClickAction(
      Tap.SINGLE, 
      new CoordinatesProvider() { 
       @Override 
       public float[] calculateCoordinates(View view) { 
        //https://leons.im/posts/how-to-get-coordinate-of-a-clickablespan-inside-a-textview/ 
        TextView textView = (TextView) view; 
        Rect parentTextViewRect = new Rect(); 

        SpannableString spannableString = (SpannableString) textView.getText(); 
        Layout textViewLayout = textView.getLayout(); 
        ClickableSpan spanToLocate = null; 

        if (spannableString.length() == 0) { 
         return new float[2]; 
        } 

        ClickableSpan[] spans = spannableString.getSpans(0, spannableString.length(), ClickableSpan.class); 
        if (spans.length > 0) { 
         spanToLocate = spans[0]; 
        } 

        if (spanToLocate == null) { 
         // no specific view found 
         throw new NoMatchingViewException.Builder() 
           .includeViewHierarchy(true) 
           .withRootView(textView) 
           .build(); 
        } 

        double startOffsetOfClickedText = spannableString.getSpanStart(spanToLocate); 
        double endOffsetOfClickedText = spannableString.getSpanEnd(spanToLocate); 
        double startXCoordinatesOfClickedText = textViewLayout.getPrimaryHorizontal((int) startOffsetOfClickedText); 
        double endXCoordinatesOfClickedText = textViewLayout.getPrimaryHorizontal((int) endOffsetOfClickedText); 

        // Get the rectangle of the clicked text 
        int currentLineStartOffset = textViewLayout.getLineForOffset((int) startOffsetOfClickedText); 
        int currentLineEndOffset = textViewLayout.getLineForOffset((int) endOffsetOfClickedText); 
        boolean keywordIsInMultiLine = currentLineStartOffset != currentLineEndOffset; 
        textViewLayout.getLineBounds(currentLineStartOffset, parentTextViewRect); 

        // Update the rectangle position to his real position on screen 
        int[] parentTextViewLocation = {0, 0}; 
        textView.getLocationOnScreen(parentTextViewLocation); 

        double parentTextViewTopAndBottomOffset = (
          parentTextViewLocation[1] - 
            textView.getScrollY() + 
            textView.getCompoundPaddingTop() 
        ); 
        parentTextViewRect.top += parentTextViewTopAndBottomOffset; 
        parentTextViewRect.bottom += parentTextViewTopAndBottomOffset; 
        parentTextViewRect.left += (
          parentTextViewLocation[0] + 
            startXCoordinatesOfClickedText + 
            textView.getCompoundPaddingLeft() - 
            textView.getScrollX() 
        ); 
        parentTextViewRect.right = (int) (
          parentTextViewRect.left + 
            endXCoordinatesOfClickedText - 
            startXCoordinatesOfClickedText 
        ); 

        int screenX = (parentTextViewRect.left + parentTextViewRect.right)/2; 
        int screenY = (parentTextViewRect.top + parentTextViewRect.bottom)/2; 
        if (keywordIsInMultiLine) { 
         screenX = parentTextViewRect.left; 
         screenY = parentTextViewRect.top; 
        } 
        return new float[]{screenX, screenY}; 
       } 
      }, 
      Press.FINGER); 
} 

ViewActionの定義

public static void addClickableSpan(SpannableString spannableString, 
           String text, 
           String subText, 
           ClickableSpan clickableSpan) { 
     int start = text.indexOf(subText); 
     int end = text.indexOf(subText) + subText.length(); 
     int flags = Spanned.SPAN_EXCLUSIVE_EXCLUSIVE; 

     spannableString.setSpan(clickableSpan, start, end, flags); 
} 

：

Util.addClickableSpan(spannableString, string, linkedString, new  ClickableSpan() { 
@Override 
public void onClick(View textView) {} 
}); 

tvAcceptTc.setText(spannableString); 
tvAcceptTc.setMovementMethod(LinkMovementMethod.getInstance());

をあなたの代わりにSpannableStringBuilderと互換性SpannableStringのSpannableを使用することができます。

申し訳ありませんが、私が使用することをお勧め、新しい男だだけ1評判を持って、私の英語は非常に悪いですcomment.Evenを追加することはできません.....

：

Spannable spannableString = (Spannable) textView.getText(); 

代わりに：すべてのコードの下

SpannableString spannableString = (SpannableString) textView.getText(); 

ポスト：

public class CustomViewActions { 

    /** 
    * click specific spannableString 
    */ 
    public static ViewAction clickClickableSpan(final CharSequence textToClick) { 
     return clickClickableSpan(-1, textToClick); 
    } 

    /** 
    * click the first spannableString 
    */ 
    public static ViewAction clickClickableSpan() { 
     return clickClickableSpan(0, null); 
    } 

    /** 
    * click the nth spannableString 
    */ 
    public static ViewAction clickClickableSpan(final int index) { 
     return clickClickableSpan(index, null); 
    }

       return "clicking on a ClickableSpan"; 
      } 

      @Override

       } 

       // Get the links inside the TextView and check if we find textToClick 
       ClickableSpan[] spans = spannableString.getSpans(0, spannableString.length(), ClickableSpan.class); 

       if (spans.length > 0) { 
        if(index >=spans.length){ 
         throw new NoMatchingViewException.Builder() 
          .includeViewHierarchy(true)

         spanToLocate.onClick(textView); 
         return; 
        } 
        for (int i = 0; i < spans.length; i++) { 
         int start = spannableString.getSpanStart(spans[i]); 
         int end = spannableString.getSpanEnd(spans[i]); 
         CharSequence sequence = spannableString.subSequence(start, end); 
         if (textToClick.toString().equals(sequence.toString())) {

          return;
