android選擇圖片或拍照圖片上傳到伺服器(包括上傳參數)

標籤：伺服器   hashmap   stringbuffer   upload   

在9ria論壇看到的，還沒測試，先Mark與大家分享一下。 最近要搞一個項目，需要上傳相簿和拍照的圖片，不負所望，終於完成了！ 不過需要說明一下，其實網上很多教程拍照的圖片，都是縮圖不是很清晰，所以需要在調用照相機的時候，事先產生一個地址，用於標識拍照的圖片URI 具體上傳代碼：1.選擇圖片和上傳介面，包括上傳完成和異常的回調監聽

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;/*** 說明：主要用於選擇檔案和上傳檔案操作*/public class MainActivity extends Activity implements OnClickListener,OnUploadProcessListener{private static final String TAG = "uploadImage";/*** 去上傳檔案*/protected static final int TO_UPLOAD_FILE = 1; /*** 上傳檔案響應*/protected static final int UPLOAD_FILE_DONE = 2; ///*** 選擇檔案*/public static final int TO_SELECT_PHOTO = 3;/*** 上傳初始化*/private static final int UPLOAD_INIT_PROCESS = 4;/*** 上傳中*/private static final int UPLOAD_IN_PROCESS = 5;/**** 這裡的這個URL是我伺服器的javaEE環境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. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);initView();}/*** 初始化資料*/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);}@Overridepublic 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, "上傳的檔案路徑出錯", Toast.LENGTH_LONG).show();}break;default:break;}}@Overrideprotected 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, "最終選擇的圖片="+picPath);Bitmap bm = BitmapFactory.decodeFile(picPath);imageView.setImageBitmap(bm);}super.onActivityResult(requestCode, resultCode, data);}/*** 上傳伺服器響應回調*/@Overridepublic 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("正在上傳中...");progressDialog.setMessage("正在上傳檔案...");progressDialog.show();String fileKey = "pic";UploadUtil uploadUtil = UploadUtil.getInstance();;uploadUtil.setOnUploadProcessListener(this); //設定監聽器監聽上傳狀態Map<String, String> params = new HashMap<String, String>();params.put("orderId", "11111");uploadUtil.uploadFile( picPath,fileKey, requestURL,params);}private Handler handler = new Handler(){@Overridepublic 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 = "響應碼："+msg.arg1+"\n響應資訊："+msg.obj+"\n耗時："+UploadUtil.getRequestTime()+"秒";uploadImageResult.setText(result);break;default:break;}super.handleMessage(msg);}};@Overridepublic void onUploadProcess(int uploadSize) {Message msg = Message.obtain();msg.what = UPLOAD_IN_PROCESS;msg.arg1 = uploadSize;handler.sendMessage(msg );}@Overridepublic void initUpload(int fileSize) {Message msg = Message.obtain();msg.what = UPLOAD_INIT_PROCESS;msg.arg1 = fileSize;handler.sendMessage(msg );}}

2.選擇圖片介面，主要涉及兩種方式：選擇圖片和及時拍照圖片

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>* 說明：主要用於選擇檔案操作*/public class SelectPicActivity extends Activity implements OnClickListener{/**** 使用照相機拍照擷取圖片*/public static final int SELECT_PIC_BY_TACK_PHOTO = 1;/**** 使用相簿中的圖片*/public static final int SELECT_PIC_BY_PICK_PHOTO = 2;/**** 從Intent擷取圖片路徑的KEY*/public static final String KEY_PHOTO_PATH = "photo_path";private static final String TAG = "SelectPicActivity";private LinearLayout dialogLayout;private Button takePhotoBtn,pickPhotoBtn,cancelBtn;/**擷取到的圖片路徑*/private String picPath;private Intent lastIntent ;private Uri photoUri;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.select_pic_layout);initView();}/*** 初始化載入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();}@Overridepublic 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;}}/*** 拍照擷取圖片*/private void takePhoto() {//執行拍照前，應該先判斷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"/**** 需要說明一下，以下操作使用照相機拍照，拍照後的圖片會存放在相簿中的* 這裡使用的這種方式有一個好處就是擷取的圖片是拍照後的原圖* 如果不實用ContentValues存放照片路徑的話，拍照後擷取的圖片為縮圖不清晰*/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,"記憶卡不存在", Toast.LENGTH_LONG).show();}}/**** 從相簿中取圖片*/private void pickPhoto() {Intent intent = new Intent();intent.setType("image/*");intent.setAction(Intent.ACTION_GET_CONTENT);startActivityForResult(intent, SELECT_PIC_BY_PICK_PHOTO);}@Overridepublic boolean onTouchEvent(MotionEvent event) {finish();return super.onTouchEvent(event);}@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {if(resultCode == Activity.RESULT_OK){doPhoto(requestCode,data);}super.onActivityResult(requestCode, resultCode, data);}/*** 選擇圖片後，擷取圖片的路徑* @param requestCode* @param data*/private void doPhoto(int requestCode,Intent data){if(requestCode == SELECT_PIC_BY_PICK_PHOTO ) //從相簿取圖片，有些手機有異常情況，請注意{if(data == null){Toast.makeText(this, "選擇圖片檔案出錯", Toast.LENGTH_LONG).show();return;}photoUri = data.getData();if(photoUri == null ){Toast.makeText(this, "選擇圖片檔案出錯", Toast.LENGTH_LONG).show();return;}}String[] pojo = {MediaStore.Images.Media.DATA};Cursor cursor = managedQuery(photoUri, pojo, null, 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, "選擇圖片檔案不正確", Toast.LENGTH_LONG).show();}}}

3. 上傳工具類，主要實現了圖片的上傳，上傳過程的初始化監聽和上傳完成的監聽，還有上傳耗時的計算

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;import java.net.MalformedURLException;import java.net.URL;import java.util.Iterator;import java.util.Map;import java.util.UUID;import android.util.Log;/*** * 上傳工具類* 支援上傳檔案和參數*/public class UploadUtil {private static UploadUtil uploadUtil;private static final String BOUNDARY = UUID.randomUUID().toString();
