1.Android端：

1.1 布局文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <TextView        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/hello" />         <TextView        android:id="@+id/mTextView1"         android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/hello" />      <TextView        android:id="@+id/mTextView2"         android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/hello" />              <Button        android:id="@+id/mButton1"         android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="@string/hello" />     </LinearLayout>

1.2 Activity：

package org.yang.android.upload;import java.io.File;import android.app.Activity;import android.os.Bundle;import android.os.Environment;import android.view.View;import android.widget.Button;import android.widget.TextView;public class AndroidUploadFileActivity extends Activity{private String newName = "linux.jpg";// 要上传的本地文件路径private String uploadFile = Environment.getExternalStorageDirectory()+ "/image/psb.jpg";// 上传到服务器的指定位置private String actionUrl = "http://172.17.151.54:8090/FinalProject/jsp/androidUploadFile";private TextView mTextView1;private TextView mTextView2;private Button mButton1;File file = new File(uploadFile);@Overridepublic void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.main);if ( file.exists() ){System.out.println("FILE IS EXISTS!!");}else{System.out.println("FILE IS NOT EXISTS!!");}System.out.println("uploadFile is " + uploadFile);mTextView1 = (TextView) findViewById(R.id.mTextView1);mTextView1.setText("FilePath：/n" + uploadFile);mTextView2 = (TextView) findViewById(R.id.mTextView2);mTextView2.setText("UploadPath：/n" + actionUrl);/* 设定mButton的onClick事件处理 */mButton1 = (Button) findViewById(R.id.mButton1);mButton1.setOnClickListener(new View.OnClickListener(){public void onClick(View v){FileUplaodUtil.uploadFile(AndroidUploadFileActivity.this.file, actionUrl);}});}}

1.2 FileUploadUtil.java文件：

2.服务器端：
