美好的一天！我正在尝试搜索从Android上传图像文件到在线MysqL数据库的基本教程,但我找不到任何.

我现在正在开展一项活动,可以将用户的个人资料图片从AndroID上传到在线服务器.

我需要的是显示一个按钮,当它被点击时,用户可以从文件中选择一个图像.有人可以指导我这样做吗？提前致谢！

解决方法:

在客户端,您可以这样做.

httpURLConnection connection = null;DataOutputStream outputStream = null;DatainputStream inputStream = null;    String pathToOurfile = "path of the image.jpeg";String urlServer = "http://xxx.xxx.xxx.xxx/uploader.PHP";String lineEnd = "\r\n";String twoHyphens = "--";String boundary =  "*****";int bytesRead, bytesAvailable, bufferSize;byte[] buffer;int maxBufferSize = 1*1024*1024;try {        fileinputStream fileInStream = new fileinputStream(new file(pathToOurfile) );        URL url = new URL(urlServer);        connection = (httpURLConnection) url.openConnection();       // Allow inputs & Outputs        connection.setDoinput(true);        connection.setDoOutput(true);        connection.setUseCaches(false);        // Enable POST method        connection.setRequestMethod("POST");        connection.setRequestProperty("Connection", "Keep-Alive");        connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);        outputStream = new DataOutputStream( connection.getoutputStream() );        outputStream.writeBytes(twoHyphens + boundary + lineEnd);        outputStream.writeBytes("Content-disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurfile +"\"" + lineEnd);        outputStream.writeBytes(lineEnd);        bytesAvailable = fileInStream.available();        bufferSize = Math.min(bytesAvailable, maxBufferSize);        buffer = new byte[bufferSize];        // Read file        bytesRead = fileInStream.read(buffer, 0, bufferSize);        while (bytesRead > 0)        {            outputStream.write(buffer, 0, bufferSize);            bytesAvailable = fileInStream.available();            bufferSize = Math.min(bytesAvailable, maxBufferSize);            bytesRead = fileInStream.read(buffer, 0, bufferSize);        }        outputStream.writeBytes(lineEnd);        outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);        // Responses from the server (code and message)        serverResponseCode = connection.getResponseCode();        serverResponseMessage = connection.getResponseMessage();        fileinputStream.close();        outputStream.flush();        outputStream.close();    }    catch (Exception ex)    {        //Exception handling    }

服务器端

<?PHP    $target_path  = "./";    $target_path = $target_path . basename( $_fileS['uploadedfile']['name']);    if(move_uploaded_file($_fileS['uploadedfile']['tmp_name'], $target_path)) {         echo "Success";    } else{        echo "Error";    }?>
