private void addReadMore(final String text, final TextView textView) { SpannableString ss = new SpannableString(text.substring(0, 270) + "... read more"); ClickableSpan clickableSpan = new ClickableSpan() { @Override public void onClick(View view) { addReadLess(text, textView); } @Override public void updateDrawState(TextPaint ds) { super.updateDrawState(ds); ds.setUnderlineText(false); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { ds.setColor(getResources().getColor(R.color.color_primary, getTheme())); } else { ds.setColor(getResources().getColor(R.color.color_primary)); } } }; ss.setSpan(clickableSpan, ss.length() - 10, ss.length() , Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); textView.setText(ss); textView.setMovementMethod(LinkMovementMethod.getInstance()); } private void addReadLess(final String text, final TextView textView) { SpannableString ss = new SpannableString(text + " read less"); ClickableSpan clickableSpan = new ClickableSpan() { @Override public void onClick(View view) { addReadMore(text, textView); } @Override public void updateDrawState(TextPaint ds) { super.updateDrawState(ds); ds.setUnderlineText(false); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { ds.setColor(getResources().getColor(R.color.color_primary, getTheme())); } else { ds.setColor(getResources().getColor(R.color.color_primary)); } } }; ss.setSpan(clickableSpan, ss.length() - 10, ss.length() , Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); textView.setText(ss); textView.setMovementMethod(LinkMovementMethod.getInstance()); }
