startActivityForResult在片段

Question

我有兩個問題：

第一：我想知道的Cuz當我使用方法1我的應用程序運行在確定2法的向度，但我改變方法2它不能運行.. 方法1（拍照簡單）：

private void takePhoto() { 

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

    Log.d(TAG, "Take photo ......."); 

    startActivityForResult(intent, REQUEST_IMAGE_CAPTURE); 
} 

和方法2：

public void dispathTakepictureIntent() { 

    Context context = getActivity(); 

    PackageManager packageManager = context.getPackageManager(); 

    if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)     ==false) 
       { 
     Toast.makeText(getActivity() 
     , "This device does not have a camera.", Toast.LENGTH_SHORT).show(); 
     return; 
    } 
     else 
     { 
     Intent takePictureIntent = new     Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

    if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) 
       { 
      File photoFile = null; 
      try { 
       photoFile = createCurrentPhotoPath(); 

       } 
       catch (IOException ex) 
        { 

       Toast.makeText(getActivity(), "null photo Path", Toast.LENGTH_LONG).show(); 
      } 

      if (photoFile != null) { 
       takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, 
         Uri.fromFile(photoFile)); 

       startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO); 

      } 
     } 
    } 

} 

---相機片段的onActivityResult：

@Override 

    public void onActivityResult(int requestCode, int resultCode, Intent data) { 

    super.onActivityResult(requestCode, resultCode, data); 

     if (requestCode == REQUEST_TAKE_PHOTO && resultCode == Activity.RESULT_OK) { 

      Bundle extras = data.getExtras(); 
      Bitmap imageBitmap = (Bitmap) extras.get("data"); 
      if (imageBitmap != null) 
       Img_show.setImageBitmap(imageBitmap); 
      else 
       Toast.makeText(getActivity(), "null photo bitmap", Toast.LENGTH_LONG).show(); 

     } else 
      Toast.makeText(getActivity(), "Cancel !", Toast.LENGTH_LONG).show(); 


    } 

主要問題：現在我有MainFragment擴展FragmentActivity（有片段相機和地圖）。但在片段相機當我

startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO); 

然後在方法onActivityResult，所述發送resultCode送花兒給人== 0儘管必須== 1; 。誰可以顯示我的問題？我的錯在哪裏？在mainFragment

注意我只要致電：

@Override 

    public void onActivityResult(int requestCode, int resultCode, Intent data) { 

     super.onActivityResult(requestCode, resultCode, data); 

    } 

感謝

嘗試像這樣...

 private static final int REQUEST_CAMERA = 2; 

    if (isDeviceSupportCamera()) { 
         Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
         startActivityForResult(intent, REQUEST_CAMERA); 
        } else { 
         showCustomToast(" No camera on this device !!"); 
        } 
    private boolean isDeviceSupportCamera() { 
      if (getActivity().getApplicationContext().getPackageManager().hasSystemFeature(
        PackageManager.FEATURE_CAMERA)) { 
       // this device has a camera 
       return true; 
      } else { 
       // no camera on this device 
       return false; 
      } 
     } 
    @Override 
     public void onActivityResult(int requestCode, int resultCode, Intent data) { 
      super.onActivityResult(requestCode, resultCode, data); 

      if (requestCode == REQUEST_CAMERA && resultCode == getActivity().RESULT_OK && null != data) { 
       Bitmap photo = (Bitmap) data.getExtras().get("data"); 
       profileImage.setImageBitmap(photo); 

       // CALL THIS METHOD TO GET THE URI FROM THE BITMAP 
       Uri tempUri = getImageUri(getActivity().getApplicationContext(), photo); 

       // CALL THIS METHOD TO GET THE ACTUAL PATH 
       File finalFile = new File(getRealPathFromURI(tempUri)); 
       decodeFile(finalFile.toString()); 
      } 
     } 
public Uri getImageUri(Context inContext, Bitmap inImage) { 
     ByteArrayOutputStream bytes = new ByteArrayOutputStream(); 
     inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes); 
     String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null); 
     return Uri.parse(path); 
    } 

    public String getRealPathFromURI(Uri uri) { 
     Cursor cursor = getActivity().getContentResolver().query(uri, null, null, null, null); 
     cursor.moveToFirst(); 
     int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
     return cursor.getString(idx); 
    } 


    // decode image 
    public void decodeFile(String filePath) { 
     // Decode image size 
     BitmapFactory.Options o = new BitmapFactory.Options(); 
     o.inJustDecodeBounds = true; 
     BitmapFactory.decodeFile(filePath, o); 
     // The new size we want to scale to 
     final int REQUIRED_SIZE = 1024; 
     // Find the correct scale value. It should be the power of 2. 
     int width_tmp = o.outWidth, height_tmp = o.outHeight; 
     int scale = 1; 
     while (true) { 
      if (width_tmp < REQUIRED_SIZE && height_tmp < REQUIRED_SIZE) 
       break; 
      width_tmp /= 2; 
      height_tmp /= 2; 
      scale *= 2; 
     } 

     // Decode with inSampleSize 
     BitmapFactory.Options o2 = new BitmapFactory.Options(); 
     o2.inSampleSize = scale; 
     bitmap = BitmapFactory.decodeFile(filePath, o2);  
     profileImage.setImageBitmap(bitmap); 
    } 

它只是一個你完全測試完整的例子能夠可靠地幫助您從相機拍攝照片....和作品像魅力.....
