的Android onActivityResult錯誤

-1

我寫了下面的代碼onActivityResult方法調用CropImage.class這將給裁剪後的圖像，但我同時從作物的活動返回Add_Customer活動的Android onActivityResult錯誤

調用CropImage活動與經過3中面臨的一個錯誤下面的方法：

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     Toast.makeText(getApplicationContext(), "Called Succesfully..." + requestCode, Toast.LENGTH_SHORT).show(); 
     if (requestCode == 1) 
     { 
      Intent intent = new Intent(Add_Customer.this,CropImage.class); 
      startActivityForResult(intent, 3); 
     } 

     if (requestCode ==3) 
     { 
      Toast.makeText(getApplicationContext(),"Photo Added Succesfully...", Toast.LENGTH_SHORT).show(); 
      File f = new File(Environment.DIRECTORY_PICTURES); 
      for (File temp : f.listFiles()) { 
       if (temp.getName().equals("temp.jpg")) { 
        f = temp; 
        break; 
       } 
      } 
      BitmapFactory.Options bitmapOptions = new BitmapFactory.Options(); 

      Bitmap bmp = BitmapFactory.decodeFile(f.getAbsolutePath(), 
        bitmapOptions); 

      viewImage.setImageBitmap(bmp); 
     } 

    }

CropImage活動的onCreate：

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_crop_image); 

final CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView); 
final ImageView croppedImageView = (ImageView)findViewById(R.id.croppedImageView); 
     // Set image for cropping 

     File f = new File(Environment.getExternalStorageDirectory().toString()); 
     for (File temp : f.listFiles()) 
     { 
      if (temp.getName().equals("temp.jpg")) 
      { 
      f = temp; 
      break; 
      } 
     } 
     try 
     { 

     BitmapFactory.Options bitmapOptions = new BitmapFactory.Options(); 

     bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(), 
     bitmapOptions); 

     cropImageView.setImageBitmap(bitmap); 



     //deleting image captured by camera 
     f.delete(); 


     } catch (Exception e) { 
     e.printStackTrace(); 
     } 




     Button cropButton = (Button)findViewById(R.id.crop_button); 
     cropButton.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View v) { 
     // Get cropped image, and show result. 
     croppedImageView.setImageBitmap(cropImageView.getCroppedBitmap()); 

     ByteArrayOutputStream bStream = new ByteArrayOutputStream(); 
     Bitmap crop = cropImageView.getCroppedBitmap(); 

     OutputStream outFile = null; 
     File file = new File(Environment.DIRECTORY_PICTURES, "temp.jpg"); 
     try { 
     outFile = new FileOutputStream(file); 
     crop.compress(Bitmap.CompressFormat.JPEG, 85, outFile); 
     outFile.flush(); 
     outFile.close(); 

     } catch (Exception e) { 
     e.printStackTrace(); 
     } 


     Intent intentMessage = new Intent(); 

     // put the message in Intent 
     intentMessage.putExtra("MESSAGE", "hello"); 
     intentMessage.putExtra("image", crop); 
     setResult(3, intentMessage); 
     // finish The activity 
     finish(); 
     } 
     }); 
     }

錯誤：

您的回調意圖沒有傳遞正確的resultCode，並且這是因爲它的崩潰。

更改您的代碼CropImage活動中的onClick）以下（：

Intent intentMessage = new Intent(); 

    // put the message in Intent 
    intentMessage.putExtra("MESSAGE", "hello"); 
    intentMessage.putExtra("image", crop); 
    setResult(RESULT_OK, intentMessage); 
    // finish The activity 
    finish();

但是我應該在哪裏通過3然後 –

你不需要通過。 Android記住您已通過「startActivityForResult（intent，3）」的請求代碼;「 –

更改後的eRRor： java.lang.RuntimeException：未將結果resultInfo {who = null，request = 3，result = -1，data = Intent {（has extras）}}傳遞給活動 –

我在onActivityResult取得使用getIntent.getByteArrayExtra（「圖像」），而不是data.getByteArrayExtra（「圖像」）的愚蠢的錯誤方法
