一、前言

每条消息根据对方有没有在规定时间内容回复，在消息底部显示一句提示语。这需要不是很常见，不过碰到了，你是不是懵了，这可咋整。
需求是每种消息都需要这样的提示语，不单是文本消息。图片消息，小视频消息，语音消息等

二、效果图

不用在意双方发的消息对不上。截的是设计图。当然图片消息，其他消息也有这样的提示语的

三、解决思路

肯定是要自定义模板（MessageItemProvider）了的。但每个消息模板都要这样的需求，看是否有一个基类，这样统一处理比较好。结果还真有（BaseMessageItemProvider）。
方案：

自定义BaseMessageItemProvider（拷贝融云原来的全部代码，在合适的位置加上你的业务代码）
在rc_message_item布局加上显示那句话的textview
然后自定义每一种消息模板，然后它继承上面自定义的BaseMessageItemProvider
至于怎么判断出状态，你们研发团队自己讨论了（实在讨论不出方案的，可私信我）

四、给出MyBaseMessageItemProvider和其中的文本消息模板MyTextMessageItemProvider示例代码

在initContent方法中我发的就是我的业务处理代码

MyTextMessageItemProvider

    if (TextUtilsCompat.getLayoutDirectionFromLocale(Locale.getDefault()) == 1) {

    }
    view.setTextSize(TypedValue.COMPLEX_UNIT_SP,16);

                            view.setText(uiMessage.getContentSpannable());
                        }
                    });
                }

            }
        });
        uiMessage.setContentSpannable(spannable);
    }

    view.setText(uiMessage.getContentSpannable());
    view.setMovementMethod(new LinkTextViewMovementMethod(new ILinkClickListener() {

        content = content.replace("\n", " ");
        if (content.length() > 100) {
            content = content.substring(0, 100);
        }

        return new SpannableString(AndroidEmoji.ensure(content));
    } else {
        return new SpannableString("");
    }
}}

这个没有做任何处理，就继承MyBaseMessageItemProvider。
有问题可私信我。
