① android的自带的httpClient 怎么上传文件

这里只贴出代码,可根据实际情况自行修改。[java] package com.lxb.uploadwithprogress.http; import java.io.File; import org.apache.http.HttpResponse;import org.apache.http.client.HttpClient;import org.apache.http.client.methods.HttpPost;import org.apache.http.entity.mime.content.FileBody;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.protocol.BasicHttpContext;import org.apache.http.protocol.HttpContext;import org.apache.http.util.EntityUtils; import android.app.ProgressDialog;import android.content.Context;import android.os.AsyncTask; import com.lxb.uploadwithprogress.http.CustomMultipartEntity.ProgressListener; public class HttpMultipartPost extends AsyncTask { private Context context;private String filePath;private ProgressDialog pd;private long totalSize; public HttpMultipartPost(Context context, String filePath) {this.context = context;this.filePath = filePath;} @Overrideprotected void onPreExecute() {pd = new ProgressDialog(context);pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);pd.setMessage(Uploading Picture…);pd.setCancelable(false);pd.show();} @Overrideprotected String doInBackground(String… params) {String serverResponse = null; HttpClient httpClient = new DefaultHttpClient();HttpContext httpContext = new BasicHttpContext();HttpPost httpPost = new HttpPost try {CustomMultipartEntity multipartContent = new CustomMultipartEntity(new ProgressListener() {@Overridepublic void transferred(long num) {publishProgress((int) ((num / (float) totalSize) * 100));}}); // We use FileBody to transfer an imagemultipartContent.addPart(data, new FileBody(new File(filePath)));totalSize = multipartContent.getContentLength(); // Send ithttpPost.setEntity(multipartContent);HttpResponse response = httpClient.execute(httpPost, httpContext);serverResponse = EntityUtils.toString(response.getEntity()); } catch (Exception e) {e.printStackTrace();} return serverResponse;} @Overrideprotected void onProgressUpdate(Integer… progress) {pd.setProgress((int) (progress[0]));} @Overrideprotected void onPostExecute(String result) {System.out.println(result: + result);pd.dismiss();} @Overrideprotected void onCancelled() {System.out.println(cancle);} }[java] package com.lxb.uploadwithprogress.http; import java.io.FilterOutputStream;import java.io.IOException;import java.io.OutputStream;import java.nio.charset.Charset; import org.apache.http.entity.mime.HttpMultipartMode;import org.apache.http.entity.mime.MultipartEntity; public class CustomMultipartEntity extends MultipartEntity { private final ProgressListener listener; public CustomMultipartEntity(final ProgressListener listener) {super();this.listener = listener;} public CustomMultipartEntity(final HttpMultipartMode mode,final ProgressListener listener) {super(mode);this.listener = listener;} public CustomMultipartEntity(HttpMultipartMode mode, final String boundary,final Charset charset, final ProgressListener listener) {super(mode, boundary, charset);this.listener = listener;} @Overridepublic void writeTo(OutputStream outstream) throws IOException {super.writeTo(new CountingOutputStream(outstream, this.listener));} public static interface ProgressListener {void transferred(long num);} public static class CountingOutputStream extends FilterOutputStream { private final ProgressListener listener;private long transferred; public CountingOutputStream(final OutputStream out,final ProgressListener listener) {super(out);this.listener = listener;this.transferred = 0;} public void write(byte[] b, int off, int len) throws IOException {out.write(b, off, len);this.transferred += len;this.listener.transferred(this.transferred);} public void write(int b) throws IOException {out.write(b);this.transferred++;this.listener.transferred(this.transferred);}} }上面为两个主要的类,下面放一个调用的Activity

② android上大文件分片上传 具体怎么弄

提供一点demo断点续传(改良版)package com.phone1000.demo09;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.RandomAccessFile;public class RandomAccessDemo { public static void main(String[] args) { // 1.找到文件 File file = new File("E:\\网络云盘\\网络云同步盘\\Android开发视频教程\\[Android开发视频教程]02_01_spinner的使用.mp4"); File file2 = new File("E:\\我的照片\\[Android开发视频教程]02_01_spinner的使用.mp4"); //2.创建流 RandomAccessFile is = null; FileOutputStream os = null; try { is = new RandomAccessFile(file,"r"); os = new FileOutputStream(file2,true); //3.定义一个容器 byte[] b = new byte[1024]; //4.定义一个长度 int len = 0 ; long oldLength = file.length(); long newLength = 0; //5.循环读数 while((len = is.read(b)) != -1){ if(newLength >= oldLength) { System.out.println("传输完成!"); break; } else{ newLength = newLength + len; is.seek(newLength); os.write(b); } }//释放资源 os.close(); is.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }}

③ Android的.apk文件怎么上传到手机

具体方法如下:

1、首先打开电脑上的qq,在首界面找到我的设备。

同时打开手机qq,并连回上无线。
