我开发了聊天应用程序。要在聊天中传输图像,我们首先将其上传到内容模块,然后将该 ID 共享给接收者。如果出现问题,我们会调用 messagelistner 中的 getFile。但是,将相同的代码放在该方法之外可以正常工作。请看下面的代码:
MyChatController.java
private MessageListener messageListener = new MessageListener() {
@Override
public void processMessage(Chat chat, Message message) {
System.out.println(String.format(">>> Message received (from=%s, to=%s): %s",from, to, message.getBody()));
if (onMessageReceivedListener != null)
{
onMessageReceivedListener.onMessageReceived(message);
}
}
};
这个方法的实现在 ChatActivity
聊天活动.java
私人 ChatController.OnMessageReceivedListener onMessageReceivedListener = new ChatController.OnMessageReceivedListener() { public void onMessageReceived(最终消息消息) { 最终字符串 from = message.getFrom().split("-")[0]; 最终字符串 messageString = message.getBody(); Log.v("----msg from----","from ap "+ from+"-----"+friend.getId().toString()); if(from.equalsIgnoreCase(friend.getId().toString())) { if(messageString.startsWith(">>在线程中"); URL url = 新 URL(imageUrl); Log.v("---CONNECTION url---","线程中---"+url); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.setRequestMethod("GET"); urlConnection.connect(); 字符串文件目录=空; 文件文件=空; 文件文件; 如果(文件类型==SELECT_IMAGE) { fileDir=SDCardRoot+"/Globr/Images"; } ffile=新文件(fileDir); if(!ffile.exists()) { ffile.mkdirs(); } 文件 = 新文件(文件目录,文件名); Log.v("---文件夹文件名---","图像文件夹文件创建---"+文件名); if(!file.exists()) { 文件.createNewFile(); } FileOutputStream fileOutput = new FileOutputStream(file); InputStream inputStream = urlConnection.getInputStream(); int totalSize = urlConnection.getContentLength(); int 下载大小 = 0; 字节[]缓冲区=新字节[1024]; int 缓冲区长度 = 0; 而 ( (bufferLength = inputStream.read(buffer)) > 0 ) { fileOutput.write(buffer, 0, bufferLength); 下载大小 += 缓冲区长度; Log.v("进度:","downloadedSize:"+downloadedSize+"totalSize:"+ totalSize) ; } 文件输出.close(); Log.v("文件:-------","文件为:"+文件); if(downloadedSize==totalSize) 文件路径=file.getAbsolutePath(); } 捕获(MalformedURLException e) { e.printStackTrace(); } 捕获(IOException e) { 文件路径=空; e.printStackTrace(); } } }。开始(); } @覆盖 公共无效onComplete(结果结果,对象o){ } }); } } }
