???????????????? android手機有自帶的照相機和圖庫，我們做的項目中有時用到上傳圖片到服務器，今天做了一個項目用到這個功能，所以把我的代碼記錄下來和大家分享，第一次寫博客希望各位大神多多批評。

???????????? 首先上一段調用android相冊和相機的代碼：

??

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//調用android自帶的照相機photoUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;startActivityForResult(intent, 1);

?

Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);//調用android的圖庫startActivityForResult(i, 2);

?

@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) { //完成照相后回調用此方法
super.onActivityResult(requestCode, resultCode, data);case 1:switch (resultCode) {case Activity.RESULT_OK://照相完成點擊確定
String sdStatus = Environment.getExternalStorageState();????

????????????? if (!sdStatus.equals(Environment.MEDIA_MOUNTED)) { // 檢測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");// 獲取相機返回的數據，并轉換為Bitmap圖片格式????

??????????????????? FileOutputStream b = null;????

??????????????????????? File file = new File("/sdcard/pk4fun/");????

???????????????????????? file.mkdirs();// 創建文件夾，名稱為pk4fun???? // 照片的命名，目標文件夾下，以當前時間數字串為名稱，即可確保每張照片名稱不相同。網上流傳的其他Demo這里的照片名稱都寫死了，則會發生無論拍照多少張，后一張總會把前一張照片覆蓋。細心的同學還可以設置這個字符串，比如加上“ＩＭＧ”字樣等；然后就會發現sd卡中myimage這個文件夾下，會保存剛剛調用相機拍出來的照片，照片名稱不會重復。????

??????????????????? String str = null;????

?????????????????? Date date = null;????

??????????????????? SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");// 獲取當前時間，進一步轉化為字符串????

?????????????????????? date = new Date(resultCode);????

???????????????? str = format.format(date);????

???????????????????? String fileName = "/sdcard/myImage/" + str + ".jpg";????

????????????????? sendBroadcast(fileName);????

?????????????????? try {?????

???????????????????? b = new FileOutputStream(fileName);?????

??????????????????? bitmap.compress(Bitmap.CompressFormat.JPEG, 100, b);// 把數據寫入文件???

??????????????? ?} catch (FileNotFoundException e) {?????

?????????????????? e.printStackTrace();????

??????????????????? } finally {????

???????????????????? ?try {????

???????????????????? ?b.flush();?????

???????????????????????????? b.close();?????

??????????????????????????? } catch (IOException e) {???

??????????????????????? ?e.printStackTrace();???

???????????????? ? }????

???????????? }???

break;case Activity.RESULT_CANCELED:// 取消break;}break;case 2:switch (resultCode) {case Activity.RESULT_OK: {Uri uri = data.getData();Cursor cursor = mActivity.getContentResolver().query(uri, null,null, null, null);cursor.moveToFirst();String imgNo = cursor.getString(0); // 圖片編號String imgPath = cursor.getString(1); // 圖片文件路徑String imgSize = cursor.getString(2); // 圖片大小String imgName = cursor.getString(3); // 圖片文件名 cursor.close();// Options options = new BitmapFactory.Options();// options.inJustDecodeBounds = false;// options.inSampleSize = 10;// Bitmap bitmap = BitmapFactory.decodeFile(imgPath, options); }break;case Activity.RESULT_CANCELED:// 取消break;}break;}

最后記得加權限

??? <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
??? <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
??? <uses-permission android:name="android.permission.CAMERA" />
??? <uses-permission android:name="android.permission.RECORD_AUDIO" />
??? <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
???
