• 解决办法

  URLSpan urlSpan;
      if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.M) {
          urlSpan = new URLSpan(uri);
      }else {
          urlSpan=new URLSpan(uri){
              @Override
              public void onClick(View widget) {
                  try {
                      super.onClick(widget);
                  }catch (ActivityNotFoundException e){
                      e.printStackTrace();
                  }
              }
          };
      }
