Android选择图片或拍照图片上传到服务器

概述最近要搞一个项目，需要上传相册和拍照的图片，不负所望，终于完成了！ 不过需要说明一下，其实网上很多教程拍照的图片，都是缩略图不是很清晰，所以需要在调用照相机的时候，事先生成一个地址，用于标识拍照的

最近要搞一个项目，需要上传相册和拍照的图片，不负所望，终于完成了！  不过需要说明一下，其实网上很多教程拍照的图片，都是缩略图不是很清晰，所以需要在调用照相机的时候，事先生成一个地址，用于标识拍照的图片URI

具体上传代码：

1.选择图片和上传界面，包括上传完成和异常的回调监听

package com.spring.sky.image.upload;   import java.util.HashMap; import java.util.Map;  import androID.app.Activity; import androID.app.ProgressDialog; import androID.content.Intent; import androID.graphics.Bitmap; import androID.graphics.BitmapFactory; import androID.os.Bundle; import androID.os.Handler; import androID.os.Message; import androID.util.Log; import androID.vIEw.VIEw; import androID.vIEw.VIEw.OnClickListener; import androID.Widget.button; import androID.Widget.ImageVIEw; import androID.Widget.Progressbar; import androID.Widget.TextVIEw; import androID.Widget.Toast;  import com.spring.sky.image.upload.network.UploadUtil; import com.spring.sky.image.upload.network.UploadUtil.OnUploadProcessListener; /**  * @author spring sky<br>  * Email :vipa1888@163.com<br>  * QQ: 840950105<br>  * 说明：主要用于选择文件和上传文件 *** 作  */ public class MainActivity extends Activity implements OnClickListener,OnUploadProcessListener{  private static final String TAG = "uploadImage";    /**   * 去上传文件   */  protected static final int TO_UPLOAD_file = 1;  /**   * 上传文件响应   */  protected static final int UPLOAD_file_DONE = 2; //  /**   * 选择文件   */  public static final int TO_SELECT_PHOTO = 3;  /**   * 上传初始化   */  private static final int UPLOAD_INIT_PROCESS = 4;  /**   * 上传中   */  private static final int UPLOAD_IN_PROCESS = 5;  /***   * 这里的这个URL是我服务器的javaEE环境URL   */  private static String requestURL = "http://192.168.10.160:8080/fileUpload/p/file!upload";  private button selectbutton,uploadbutton;  private ImageVIEw imageVIEw;  private TextVIEw uploadImageResult;  private Progressbar progressbar;    private String picPath = null;  private ProgressDialog progressDialog;    /** Called when the activity is first created. */  @OverrIDe  public voID onCreate(Bundle savedInstanceState) {   super.onCreate(savedInstanceState);   setContentVIEw(R.layout.main);   initVIEw();  }    /**   * 初始化数据   */  private voID initVIEw() {   selectbutton = (button) this.findVIEwByID(R.ID.selectimage);   uploadbutton = (button) this.findVIEwByID(R.ID.uploadImage);   selectbutton.setonClickListener(this);   uploadbutton.setonClickListener(this);   imageVIEw = (ImageVIEw) this.findVIEwByID(R.ID.imageVIEw);   uploadImageResult = (TextVIEw) findVIEwByID(R.ID.uploadImageResult);   progressDialog = new ProgressDialog(this);   progressbar = (Progressbar) findVIEwByID(R.ID.progressbar1);  }   @OverrIDe  public voID onClick(VIEw v) {   switch (v.getID()) {   case R.ID.selectimage:    Intent intent = new Intent(this,SelectPicActivity.class);    startActivityForResult(intent,TO_SELECT_PHOTO);    break;   case R.ID.uploadImage:    if(picPath!=null)    {     handler.sendEmptyMessage(TO_UPLOAD_file);    }else{     Toast.makeText(this,"上传的文件路径出错",Toast.LENGTH_LONG).show();    }    break;   default:    break;   }  }   @OverrIDe  protected voID onActivityResult(int requestCode,int resultCode,Intent data) {   if(resultCode==Activity.RESulT_OK && requestCode == TO_SELECT_PHOTO)   {    picPath = data.getStringExtra(SelectPicActivity.KEY_PHOTO_PATH);    Log.i(TAG,"最终选择的图片="+picPath);    Bitmap bm = BitmapFactory.decodefile(picPath);    imageVIEw.setimageBitmap(bm);   }   super.onActivityResult(requestCode,resultCode,data);  }     /**   * 上传服务器响应回调   */  @OverrIDe  public voID onUploadDone(int responseCode,String message) {   progressDialog.dismiss();   Message msg = Message.obtain();   msg.what = UPLOAD_file_DONE;   msg.arg1 = responseCode;   msg.obj = message;   handler.sendMessage(msg);  }    private voID toUploadfile()  {   uploadImageResult.setText("正在上传中...");   progressDialog.setMessage("正在上传文件...");   progressDialog.show();   String fileKey = "pic";   UploadUtil uploadUtil = UploadUtil.getInstance();;   uploadUtil.setonUploadProcessListener(this); //设置监听器监听上传状态      Map<String,String> params = new HashMap<String,String>();   params.put("orderID","11111");   uploadUtil.uploadfile( picPath,fileKey,requestURL,params);  }    private Handler handler = new Handler(){   @OverrIDe   public voID handleMessage(Message msg) {    switch (msg.what) {    case TO_UPLOAD_file:     toUploadfile();     break;        case UPLOAD_INIT_PROCESS:     progressbar.setMax(msg.arg1);     break;    case UPLOAD_IN_PROCESS:     progressbar.setProgress(msg.arg1);     break;    case UPLOAD_file_DONE:     String result = "响应码："+msg.arg1+"\n响应信息："+msg.obj+"\n耗时："+UploadUtil.getRequestTime()+"秒";     uploadImageResult.setText(result);     break;    default:     break;    }    super.handleMessage(msg);   }     };   @OverrIDe  public voID onUploadProcess(int uploadSize) {   Message msg = Message.obtain();   msg.what = UPLOAD_IN_PROCESS;   msg.arg1 = uploadSize;   handler.sendMessage(msg );  }   @OverrIDe  public voID initUpload(int fileSize) {   Message msg = Message.obtain();   msg.what = UPLOAD_INIT_PROCESS;   msg.arg1 = fileSize;   handler.sendMessage(msg );  }   } 

2.选择图片界面，主要涉及两种方式：选择图片和及时拍照图片

package com.spring.sky.image.upload;  import androID.app.Activity; import androID.content.ContentValues; import androID.content.Intent; import androID.database.Cursor; import androID.net.Uri; import androID.os.Bundle; import androID.os.Environment; import androID.provIDer.MediaStore; import androID.util.Log; import androID.vIEw.MotionEvent; import androID.vIEw.VIEw; import androID.vIEw.VIEw.OnClickListener; import androID.Widget.button; import androID.Widget.linearLayout; import androID.Widget.Toast;  /**  * @author spring sky<br>  * Email :vipa1888@163.com<br>  * QQ: 840950105<br>  * @version 创建时间：2012-11-22 上午9:20:03  * 说明：主要用于选择文件 *** 作  */  public class SelectPicActivity extends Activity implements OnClickListener{   /***   * 使用照相机拍照获取图片   */  public static final int SELECT_PIC_BY_TACK_PHOTO = 1;  /***   * 使用相册中的图片   */  public static final int SELECT_PIC_BY_PICK_PHOTO = 2;    /***   * 从Intent获取图片路径的KEY   */  public static final String KEY_PHOTO_PATH = "photo_path";    private static final String TAG = "SelectPicActivity";    private linearLayout dialogLayout;  private button takePhotoBtn,pickPhotoBtn,cancelBtn;   /**获取到的图片路径*/  private String picPath;    private Intent lastIntent ;    private Uri photoUri;  @OverrIDe  protected voID onCreate(Bundle savedInstanceState) {   super.onCreate(savedInstanceState);   setContentVIEw(R.layout.select_pic_layout);   initVIEw();  }  /**   * 初始化加载VIEw   */  private voID initVIEw() {   dialogLayout = (linearLayout) findVIEwByID(R.ID.dialog_layout);   dialogLayout.setonClickListener(this);   takePhotoBtn = (button) findVIEwByID(R.ID.btn_take_photo);   takePhotoBtn.setonClickListener(this);   pickPhotoBtn = (button) findVIEwByID(R.ID.btn_pick_photo);   pickPhotoBtn.setonClickListener(this);   cancelBtn = (button) findVIEwByID(R.ID.btn_cancel);   cancelBtn.setonClickListener(this);      lastIntent = getIntent();  }   @OverrIDe  public voID onClick(VIEw v) {   switch (v.getID()) {   case R.ID.dialog_layout:    finish();    break;   case R.ID.btn_take_photo:    takePhoto();    break;   case R.ID.btn_pick_photo:    pickPhoto();    break;   default:    finish();    break;   }  }   /**   * 拍照获取图片   */  private voID takePhoto() {   //执行拍照前，应该先判断SD卡是否存在   String SDState = Environment.getExternalStorageState();   if(SDState.equals(Environment.MEDIA_MOUNTED))   {        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//"androID.media.action.IMAGE_CAPTURE"    /***     * 需要说明一下，以下 *** 作使用照相机拍照，拍照后的图片会存放在相册中的     * 这里使用的这种方式有一个好处就是获取的图片是拍照后的原图     * 如果不实用ContentValues存放照片路径的话，拍照后获取的图片为缩略图不清晰     */    ContentValues values = new ContentValues();    photoUri = this.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,values);    intent.putExtra(androID.provIDer.MediaStore.EXTRA_OUTPUT,photoUri);    /**-----------------*/    startActivityForResult(intent,SELECT_PIC_BY_TACK_PHOTO);   }else{    Toast.makeText(this,"内存卡不存在",Toast.LENGTH_LONG).show();   }  }   /***   * 从相册中取图片   */  private voID pickPhoto() {   Intent intent = new Intent();   intent.setType("image/*");   intent.setAction(Intent.ACTION_GET_CONTENT);   startActivityForResult(intent,SELECT_PIC_BY_PICK_PHOTO);  }    @OverrIDe  public boolean ontouchEvent(MotionEvent event) {   finish();   return super.ontouchEvent(event);  }      @OverrIDe  protected voID onActivityResult(int requestCode,Intent data) {   if(resultCode == Activity.RESulT_OK)   {    doPhoto(requestCode,data);   }   super.onActivityResult(requestCode,data);  }    /**   * 选择图片后，获取图片的路径   * @param requestCode   * @param data   */  private voID doPhoto(int requestCode,Intent data)  {   if(requestCode == SELECT_PIC_BY_PICK_PHOTO ) //从相册取图片，有些手机有异常情况，请注意   {    if(data == null)    {     Toast.makeText(this,"选择图片文件出错",Toast.LENGTH_LONG).show();     return;    }    photoUri = data.getData();    if(photoUri == null )    {     Toast.makeText(this,Toast.LENGTH_LONG).show();     return;    }   }   String[] pojo = {MediaStore.Images.Media.DATA};   Cursor cursor = managedquery(photoUri,pojo,null,null);    if(cursor != null )   {    int columnIndex = cursor.getColumnIndexOrThrow(pojo[0]);    cursor.movetoFirst();    picPath = cursor.getString(columnIndex);    cursor.close();   }   Log.i(TAG,"imagePath = "+picPath);   if(picPath != null && ( picPath.endsWith(".png") || picPath.endsWith(".PNG") ||picPath.endsWith(".jpg") ||picPath.endsWith(".JPG") ))   {    lastIntent.putExtra(KEY_PHOTO_PATH,picPath);    setResult(Activity.RESulT_OK,lastIntent);    finish();   }else{    Toast.makeText(this,"选择图片文件不正确",Toast.LENGTH_LONG).show();   }  } } 

3. 上传工具类，主要实现了图片的上传，上传过程的初始化监听和上传完成的监听，还有上传耗时的计算

package com.spring.sky.image.upload.network;  import java.io.DataOutputStream; import java.io.file; import java.io.fileinputStream; import java.io.IOException; import java.io.inputStream; import java.net.httpURLConnection;

   return;   }    Log.i(TAG,"请求的URL=" + RequestURL);   Log.i(TAG,"请求的filename=" + file.getname());   Log.i(TAG,"请求的fileKey=" + fileKey);   new Thread(new Runnable() { //开启线程上传文件    @OverrIDe    public voID run() {     toUploadfile(file,param);
