相機和畫廊修剪選項

Question

我在我的應用程序中使用相機選項，但它只適用於某些設備。另外我需要裁剪選項。

super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == GALLERY_CODE && resultCode == RESULT_OK && null != data) { 

     mImageCaptureUri = data.getData(); 
     System.out.println("Gallery Image URI : "+mImageCaptureUri); 
     CropingIMG(); 

    } 
} 

Answer 1

要解決問題的相機，我用下面的方法

1. CameraIntentHelper

2. 的onSaveInstanceState

3. onRestoreInstanceState

4. onActivityResult

   private void selectImage() { 
   
   final CharSequence[] options = {"Take Photo", "Choose from Gallery", "Cancel"}; 
   AlertDialog.Builder builder = new AlertDialog.Builder(PhotoSuiteActivity.this); 
   builder.setTitle("Add Photo!"); 
   builder.setItems(options, new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int item) { 
   
        if (options[item].equals("Take Photo")) { 
         if (mCameraIntentHelper != null) { 
          mCameraIntentHelper.startCameraIntent(); 
         } else { 
          Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
          String imageFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/picture.png"; 
          File imageFile = new File(imageFilePath); 
          picUri = Uri.fromFile(imageFile); // convert path to Uri 
          takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, picUri); 
          startActivityForResult(takePictureIntent, CAMERA_CAPTURE); 
         } 
        } else if (options[item].equals("Choose from Gallery")) { 
         Toast.makeText(PhotoSuiteActivity.this, "Not yet Ready...!", Toast.LENGTH_SHORT).show(); 
         Intent galleryIntent = new Intent(Intent.ACTION_PICK, 
           android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
         // Start the Intent 
         startActivityForResult(galleryIntent, PICK_IMAGE_REQUEST); 
        } else if (options[item].equals("Cancel")) { 
         dialog.dismiss(); 
        } 
       } 
   }); 
   builder.show(); 
   
   } 
   
   private void setupCameraIntentHelper() { 
       mCameraIntentHelper = new CameraIntentHelper(this, new CameraIntentHelperCallback() { 
        @Override 
        public void onPhotoUriFound(Date dateCameraIntentStarted, Uri photoUri, int rotateXDegrees) { 
         messageView.setText(getString(R.string.activity_camera_intent_photo_uri_found) + photoUri.toString()); 
         mImageCaptureUri = photoUri; 
         Bitmap photo = BitmapHelper.readBitmap(PhotoSuiteActivity.this, photoUri); 
         if (photo != null) { 
          photo = BitmapHelper.shrinkBitmap(photo, 300, rotateXDegrees); 
          imageView.setImageBitmap(photo); 
          CropingIMG(); 
         } 
        } 
       @Override 
       public void deletePhotoWithUri(Uri photoUri) { 
        BitmapHelper.deleteImageWithUriIfExists(photoUri, PhotoSuiteActivity.this); 
       } 
   
       @Override 
       public void onSdCardNotMounted() { 
        Toast.makeText(getApplicationContext(), getString(R.string.error_sd_card_not_mounted), Toast.LENGTH_LONG).show(); 
       } 
   
       @Override 
       public void onCanceled() { 
        Toast.makeText(getApplicationContext(), getString(R.string.warning_camera_intent_canceled), Toast.LENGTH_LONG).show(); 
       } 
   
       @Override 
       public void onCouldNotTakePhoto() { 
        Toast.makeText(getApplicationContext(), getString(R.string.error_could_not_take_photo), Toast.LENGTH_LONG).show(); 
       } 
   
       @Override 
       public void onPhotoUriNotFound() { 
        messageView.setText(getString(R.string.activity_camera_intent_photo_uri_not_found)); 
       } 
   
       @Override 
       public void logException(Exception e) { 
        Toast.makeText(getApplicationContext(), getString(R.string.error_sth_went_wrong), Toast.LENGTH_LONG).show(); 
        Log.d(getClass().getName(), e.getMessage()); 
       } 
   }); 
   }
