android选择图片或拍照图片上传到服务器(包括上传参数)

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

[java]view plain copypackagecom.spring.sky.image.upload; importjava.util.HashMap; importjava.util.Map; importandroid.app.Activity; importandroid.app.ProgressDialog; importandroid.content.Intent; importandroid.graphics.Bitmap; importandroid.graphics.BitmapFactory; importandroid.os.Bundle; importandroid.os.Handler; importandroid.os.Message; importandroid.util.Log; importandroid.view.View; importandroid.view.View.OnClickListener; importandroid.widget.Button; importandroid.widget.ImageView; importandroid.widget.ProgressBar; importandroid.widget.TextView; importandroid.widget.Toast; importcom.spring.sky.work.UploadUtil; importcom.spring.sky.work.UploadUtil.OnUploadProcessListener; /** *@authorspringsky<br> *Email:vipa1888@<br> *QQ:840950105<br> *说明：主要用于选择文件和上传文件操作 */ publicclassMainActivityextendsActivityimplementsOnClickListener,OnUploadProcessListener{ privatestaticfinalStringTAG="uploadImage"; /** *去上传文件 */ protectedstaticfinalintTO_UPLOAD_FILE=1; /** *上传文件响应 */ protectedstaticfinalintUPLOAD_FILE_DONE=2;// /** *选择文件 */ publicstaticfinalintTO_SELECT_PHOTO=3; /** *上传初始化 */ privatestaticfinalintUPLOAD_INIT_PROCESS=4; /** *上传中 */ privatestaticfinalintUPLOAD_IN_PROCESS=5; /*** *这里的这个URL是我服务器的javaEE环境URL */ privatestaticStringrequestURL="http://192.168.10.160:8080/fileUpload/p/file!upload"; privateButtonselectButton,uploadButton; privateImageViewimageView; privateTextViewuploadImageResult; privateProgressBarprogressBar; privateStringpicPath=null; privateProgressDialogprogressDialog; /**Calledwhentheactivityisfirstcreated.*/ @Override publicvoidonCreate(BundlesavedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.main); initView(); } /** *初始化数据 */ privatevoidinitView(){ 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=newProgressDialog(this); progressBar=(ProgressBar)findViewById(R.id.progressBar1); } @Override publicvoidonClick(Viewv){ switch(v.getId()){ caseR.id.selectImage: Intentintent=newIntent(this,SelectPicActivity.class); startActivityForResult(intent,TO_SELECT_PHOTO); break; caseR.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 protectedvoidonActivityResult(intrequestCode,intresultCode,Intentdata){ 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); Bitmapbm=BitmapFactory.decodeFile(picPath); imageView.setImageBitmap(bm); } super.onActivityResult(requestCode,resultCode,data); } /** *上传服务器响应回调 */ @Override publicvoidonUploadDone(intresponseCode,Stringmessage){ progressDialog.dismiss(); Messagemsg=Message.obtain(); msg.what=UPLOAD_FILE_DONE; msg.arg1=responseCode; msg.obj=message; handler.sendMessage(msg); } privatevoidtoUploadFile() { uploadImageResult.setText("正在上传中..."); progressDialog.setMessage("正在上传文件..."); progressDialog.show(); StringfileKey="pic"; UploadUtiluploadUtil=UploadUtil.getInstance();; uploadUtil.setOnUploadProcessListener(this);//设置监听器监听上传状态 Map<String,String>params=newHashMap<String,String>(); params.put("orderId","11111"); uploadUtil.uploadFile(picPath,fileKey,requestURL,params); } privateHandlerhandler=newHandler(){ @Override publicvoidhandleMessage(Messagemsg){ switch(msg.what){ caseTO_UPLOAD_FILE: toUploadFile(); break; caseUPLOAD_INIT_PROCESS: progressBar.setMax(msg.arg1); break; caseUPLOAD_IN_PROCESS: progressBar.setProgress(msg.arg1); break; caseUPLOAD_FILE_DONE: Stringresult="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 publicvoidonUploadProcess(intuploadSize){ Messagemsg=Message.obtain(); msg.what=UPLOAD_IN_PROCESS; msg.arg1=uploadSize; handler.sendMessage(msg); } @Override publicvoidinitUpload(intfileSize){ Messagemsg=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

[java]view plain copypackagecom.spring.sky.image.upload; importandroid.app.Activity; importandroid.content.ContentValues; importandroid.content.Intent; importandroid.database.Cursor; .Uri; importandroid.os.Bundle; importandroid.os.Environment; importandroid.provider.MediaStore; importandroid.util.Log; importandroid.view.MotionEvent; importandroid.view.View; importandroid.view.View.OnClickListener; importandroid.widget.Button; importandroid.widget.LinearLayout; importandroid.widget.Toast; /** *@authorspringsky<br> *Email:vipa1888@<br> *QQ:840950105<br> *@version创建时间：-11-22上午9:20:03 *说明：主要用于选择文件操作 */ publicclassSelectPicActivityextendsActivityimplementsOnClickListener{ /*** *使用照相机拍照获取图片 */ publicstaticfinalintSELECT_PIC_BY_TACK_PHOTO=1; /*** *使用相册中的图片 */ publicstaticfinalintSELECT_PIC_BY_PICK_PHOTO=2; /*** *从Intent获取图片路径的KEY */ publicstaticfinalStringKEY_PHOTO_PATH="photo_path"; privatestaticfinalStringTAG="SelectPicActivity"; privateLinearLayoutdialogLayout; privateButtontakePhotoBtn,pickPhotoBtn,cancelBtn; /**获取到的图片路径*/ privateStringpicPath; privateIntentlastIntent; privateUriphotoUri; @Override protectedvoidonCreate(BundlesavedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.select_pic_layout); initView(); } /** *初始化加载View */ privatevoidinitView(){ 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 publicvoidonClick(Viewv){ switch(v.getId()){ caseR.id.dialog_layout: finish(); break; caseR.id.btn_take_photo: takePhoto(); break; caseR.id.btn_pick_photo: pickPhoto(); break; default: finish(); break; } } /** *拍照获取图片 */ privatevoidtakePhoto(){ //执行拍照前，应该先判断SD卡是否存在 StringSDState=Environment.getExternalStorageState(); if(SDState.equals(Environment.MEDIA_MOUNTED)) { Intentintent=newIntent(MediaStore.ACTION_IMAGE_CAPTURE);//"android.media.action.IMAGE_CAPTURE" /*** *需要说明一下，以下操作使用照相机拍照，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 */ ContentValuesvalues=newContentValues(); 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 */ privatevoidpickPhoto(){ Intentintent=newIntent(); intent.setType("image/*"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(intent,SELECT_PIC_BY_PICK_PHOTO); } @Override publicbooleanonTouchEvent(MotionEventevent){ finish(); returnsuper.onTouchEvent(event); } @Override protectedvoidonActivityResult(intrequestCode,intresultCode,Intentdata){ if(resultCode==Activity.RESULT_OK) { doPhoto(requestCode,data); } super.onActivityResult(requestCode,resultCode,data); } /** *选择图片后，获取图片的路径 *@paramrequestCode *@paramdata */ privatevoiddoPhoto(intrequestCode,Intentdata) { 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,"选择图片文件出错",Toast.LENGTH_LONG).show(); return; } } String[]pojo={MediaStore.Images.Media.DATA}; Cursorcursor=managedQuery(photoUri,pojo,null,null,null); if(cursor!=null) { intcolumnIndex=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

[java]view plain copypackagecom.spring.sky.work; importjava.io.DataOutputStream; importjava.io.File; importjava.io.FileInputStream; importjava.io.IOException; importjava.io.InputStream; .HttpURLConnection; .MalformedURLException; .URL; importjava.util.Iterator; importjava.util.Map; importjava.util.UUID; importandroid.util.Log; /** * *上传工具类 *@authorspringsky<br> *Email:vipa1888@<br> *QQ:840950105<br> *支持上传文件和参数 */ publicclassUploadUtil{ privatestaticUploadUtiluploadUtil; privatestaticfinalStringBOUNDARY=UUID.randomUUID().toString();//边界标识随机生成 privatestaticfinalStringPREFIX="--"; privatestaticfinalStringLINE_END="\r\n"; privatestaticfinalStringCONTENT_TYPE="multipart/form-data";//内容类型 privateUploadUtil(){ } /** *单例模式获取上传工具类 *@return */ publicstaticUploadUtilgetInstance(){ if(null==uploadUtil){ uploadUtil=newUploadUtil(); } returnuploadUtil; } privatestaticfinalStringTAG="UploadUtil"; privateintreadTimeOut=10*1000;//读取超时 privateintconnectTimeout=10*1000;//超时时间 /*** *请求使用多长时间 */ privatestaticintrequestTime=0; privatestaticfinalStringCHARSET="utf-8";//设置编码 /*** *上传成功 */ publicstaticfinalintUPLOAD_SUCCESS_CODE=1;

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); newThread(newRunnable(){//开启线程上传文件 @Override publicvoidrun(){ toUploadFile(file,fileKey,RequestURL,param);

sb.append("Content-Disposition:form-data;name=\""+fileKey +"\";filename=\""+file.getName()+"\""+LINE_END); sb.append("Content-Type:image/pjpeg"+LINE_END);//这里配置的Content-type很重要的，用于服务器端辨别文件的类型的 sb.append(LINE_END); params=sb.toString(); sb=null; Log.i(TAG,file.getName()+"="+params+"##"); dos.write(params.getBytes()); /**上传文件*/ InputStreamis=newFileInputStream(file); onUploadProcessListener.initUpload((int)file.length()); byte[]bytes=newbyte[1024]; intlen=0; intcurLen=0; while((len=is.read(bytes))!=-1){ curLen+=len; dos.write(bytes,0,len); onUploadProcessListener.onUploadProcess(curLen); } is.close(); dos.write(LINE_END.getBytes()); byte[]end_data=(PREFIX+BOUNDARY+PREFIX+LINE_END).getBytes(); dos.write(end_data); dos.flush(); // //dos.write(tempOutputStream.toByteArray()); /** *获取响应码200=成功当响应成功，获取响应的流 */ intres=conn.getResponseCode();
