如何用EditText中的图像替换String？ [英] How to replace String with an image inside an EditText?

问题描述

我目前正在开发一个简单的聊天应用程序。我想在这个应用程序中添加表情符号功能。
我已经有了一个从其他用户接收字符串的函数。我想要的是 - 如果用户发送的文本包含CharSequence，如：D或：p，我希望将它们更改为表情符号。我该如何实现这个功能？

I am currently working on a simple chat application. I want to add emoticons features in this app. I already have a function to receive string from other users. What I want is- If the text that user sent contains CharSequence like ":D" or ":p", I want them to be changed into the emoticons. How can I implement this function?

我想要一个这样的函数：

I want a function like this:

public void updateMessage(){
    if (receivedMessage.contains(":D")){
        receivedMessage.replace(":D",image);
    }
    messageLog.append(receivedMessage);
}

如果可能，请帮助我。如果还有其他方法，请提及。

Please help me if this is possible. If there are other ways, please mention them.

推荐答案

你可以这样尝试

 if (rosan.contains(":p")){
            int span = abc.indexOf(":p");
            res = getResources().getDrawable(R.drawable.myImage); 
            res.setBounds(0, 0, res.getIntrinsicWidth(), res.getIntrinsicHeight());
            span = new ImageSpan(res, ImageSpan.ALIGN_BASELINE);
            ss.setSpan(span, startSpan, startSpan+2, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
            rosan = rosan.replaceFirst(":D","  "); //replace with two blank spaces.
        }
