Using ClickableSpan may still cause leaks even on versions higher than KitKat. If you look into implementation of the ClickableSpan you will notice that it doesn't extend NoCopySpan, so it leaks in onSaveInstanceState() like described in @DmitryKorobeinikov and @ChrisHorner answers. So the solution would be to create a custom class that extends ClickableSpan and NoCopySpan.

解決辦法也來自上面的網(wǎng)址：

public static class NoRefCopySpan  extends ClickableSpan implements NoCopySpan{

        @Override
        public void onClick(@NonNull View widget) {

        }

        @Override
        public void updateDrawState(TextPaint ds) {
           super.updateDrawState(ds);
        }

    }

使用

         spannable.setSpan(new NoRefCopySpan() {
                  @Override
                  public void onClick(View widget) { 
                  }
    
                 public void updateDrawState(TextPaint ds) {
                             
                }
                }, start, start + tagNameMatch.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
