Set Text View ellipsize and add view more at end

und fügte hinzu, die mehr Ansicht gefolgt und sehen weniger in der Listenansicht item.but das Problem auf eine Rolle beginnt, mehr manchmal verschwindet und die ganze Textansicht wird automatisch erweitert.Wie kann ich das beheben, bitte helfen.

Below Lösung Mehr anzeigen Option hinzufügen, wenn Textlänge größer als 150 ist und wird ellipsize Mehr um den Text zu 150 characters.On Klicken auf Ansicht wird es vollständigen Text mit anzeigen Weniger Option zeigen und klicken Sie auf anzeigen Weniger wieder wird es den Text zu 150 Zeichen ellipsize.Es funktioniert gut mit Textansicht recyclerview item und sollte auch mit listview arbeiten.

if(inputText.length()>150) 
     { 
      String text=inputText.substring(0,150)+"..."; 
      final String fulltext=inputText; 

      final SpannableString ss = new SpannableString(text+"View More"); 

      ClickableSpan span1 = new ClickableSpan() { 
       @Override 
       public void onClick(View textView) { 
        // do some thing 
        SpannableString ss1 = new SpannableString(fulltext+"Show Less"); 
        ClickableSpan span2 = new ClickableSpan() { 
         @Override 
         public void onClick(View textView) { 
          // do some thing 
          textView.setText(ss); 
          textView.setMovementMethod(LinkMovementMethod.getInstance()); 

         } 
        }; 
        ss1.setSpan(span2, fulltext.length(), ss1.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 
        ss1.setSpan(new ForegroundColorSpan(Color.BLUE), fulltext.length(), ss1.length(), 
          Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); 


        textView.setText(ss1); 
        textView.setMovementMethod(LinkMovementMethod.getInstance()); 
       } 
      }; 
      ss.setSpan(span1, 153, 162, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 
      ss.setSpan(new ForegroundColorSpan(Color.BLUE), 153,162, 
        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); 

      textView.setText(ss); 
      textView.setMovementMethod(LinkMovementMethod.getInstance()); 
     } 
else 
     { 
      textView.setText(inputText); 
     }
