android调用webservice实现图片上传

下面是实例中的步骤及相应的代码

1.android调用webservice使用ksoap,需要引入ksoap2-android-assembly-2.6.4-jar-with-dependencies.jar

2.AndroidManifest.xml中需添加相应的权限，例子：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.camera"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="9" />

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 　　<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/> <uses-permission android:name="android.permission.INTERNET"/>
    
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.camera.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    
</manifest>

3.activity_main.xml文件代码

<?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">

    <Button 
        android:id="@+id/button"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="点击启动相机"/>
    <Button 
        android:id="@+id/savePic"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="保存图片到服务器"/>
    <TextView 
        android:id="@+id/textView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
    
    <ImageView 
        android:id="@+id/imageView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="#999999" />

    
</LinearLayout>

4.MainActivity具体代码

package com.example.camera;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

import org.kobjects.base64.Base64;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;

public class MainActivity extends Activity {
	TextView tv = null;
	String fileName = "/sdcard/myImage/my.jpg"; //图片保存sd地址
	String namespace = "http://webservice.service.com";  // 命名空间  
    String url = "http://192.168.200.19:8080/Web/webservices/Portal";  //对应的url
    String methodName = "uploadImage"; //webservice方法
	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		tv = (TextView)findViewById(R.id.textView);
		
		//启用相机按钮
		Button button = (Button) findViewById(R.id.button);
		button.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
				startActivityForResult(intent, 1);
			}
		});
		
		//保存图片到服务器按钮（通过webservice实现）
		Button saveButton = (Button) findViewById(R.id.savePic);
		saveButton.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				testUpload();
			}
		});
	}

	/**
	 * 拍照完成后，回掉的方法
	 */
	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		super.onActivityResult(requestCode, resultCode, data);
		if (resultCode == Activity.RESULT_OK) {
			String sdStatus = Environment.getExternalStorageState();
			if (!sdStatus.equals(Environment.MEDIA_MOUNTED)) { // 检测sd是否可用
				Log.v("TestFile",
				"SD card is not avaiable/writeable right now.");
				return;
			}

			Bundle bundle = data.getExtras();
			Bitmap bitmap = (Bitmap) bundle.get("data");// 获取相机返回的数据，并转换为Bitmap图片格式
			FileOutputStream b = null;
			File file = new File("/sdcard/myImage/");
			file.mkdirs();// 创建文件夹
			try {
				b = new FileOutputStream(fileName);
				bitmap.compress(Bitmap.CompressFormat.JPEG, 100, b);// 把数据写入文件
			} catch (FileNotFoundException e) {
				e.printStackTrace();
			} finally {
				try {
					b.flush();
					b.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
			((ImageView) findViewById(R.id.imageView)).setImageBitmap(bitmap);// 将图片显示在ImageView里
		}
	}
	
	/**
	 * 图片上传方法
	 * 
	 * 1.把图片信息通过Base64转换成字符串
	 * 2.调用connectWebService方法实现上传
	 */
	private void testUpload(){  
        try{    
            FileInputStream fis = new FileInputStream(fileName);  
            ByteArrayOutputStream baos = new ByteArrayOutputStream();  
            byte[] buffer = new byte[1024];  
            int count = 0;  
            while((count = fis.read(buffer)) >= 0){  
                baos.write(buffer, 0, count);  
            }  
            String uploadBuffer = new String(Base64.encode(baos.toByteArray()));  //进行Base64编码  
            connectWebService(uploadBuffer);   
            Log.i("connectWebService", "start");  
            fis.close();  
        }catch(Exception e){  
            e.printStackTrace();  
        }  
    } 
	
	/**
	 * 通过webservice实现图片上传
	 * 
	 * @param imageBuffer
	 */
	private void connectWebService(String imageBuffer) {  
        //以下就是 调用过程了，不明白的话 请看相关webservice文档     
        SoapObject soapObject = new SoapObject(namespace, methodName);      
        soapObject.addProperty("filename", "my.jpg");  //参数1   图片名  
        soapObject.addProperty("image", imageBuffer);   //参数2  图片字符串  
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(  
                SoapEnvelope.VER11);  
        envelope.dotNet = false;  
        envelope.setOutputSoapObject(soapObject);  
        HttpTransportSE httpTranstation = new HttpTransportSE(url);  
        try {  
            httpTranstation.call(namespace, envelope);  
            Object result = envelope.getResponse();  
            Log.i("connectWebService", result.toString());  
            tv.setText(result.toString());
        } catch (Exception e) {  
            e.printStackTrace();
            tv.setText(e.getStackTrace().toString());
        }  
    }  

}

5.服务端webservice方法

public String uploadImage(String filename, String image) { 
	    FileOutputStream fos = null;  
	    try{  
	        String toDir = "D:\\work\\image";   //存储路径  
	        byte[] buffer = new BASE64Decoder().decodeBuffer(image);   //对android传过来的图片字符串进行解码   
	        File destDir = new File(toDir);    
	        if(!destDir.exists()) {
	        	destDir.mkdir();  
	        }
	        fos = new FileOutputStream(new File(destDir,filename));   //保存图片  
	        fos.write(buffer);  
	        fos.flush();  
	        fos.close();  
	        return "上传图片成功!" + "图片路径为：" + toDir;  
	    }catch (Exception e){  
	        e.printStackTrace();  
	    }  
	    return "上传图片失败！";  
	}  

本实例webservice发布用的是cxf,android SDK用的是2.3.3

6.操作步骤

（1）点击“点击启动相机”按钮，回到拍照模式下，拍照完成，回到初始界面，显示刚拍的照片

（2）点击“保存照片到服务器”按钮，通过webservice把照片保存到服务器中，TextView显示保存信息。

7.截图效果如下：
