我试图从相机和画廊获取图像并裁剪它.
问题是我在onActivityResult调用后返回我的活动而不是片段.

...
            FragmentTransaction t = fragmentManager.beginTransaction();
            LogInFragment logFrag = new LogInFragment();
            t.replace(R.id.fragment_container,logFrag);
            t.commit();
...
     @Override
        protected void onActivityResult(int requestCode,int resultCode,Intent data) {
            super.onActivityResult(requestCode,resultCode,data);
        }

活动布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/fragment_container"
                android:background="@color/textWhite"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent">
 
</RelativeLayout>

我还选择了’SherlockFragment’,我选择了图像：

startImagePickerDialog(this);
 
 
public void startImagePickerDialog() {
        AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(getSherlockActivity());
        myAlertDialog.setTitle("Upload Pictures Option");
        myAlertDialog.setMessage("How do you want to set your picture?");
 
        myAlertDialog.setPositiveButton("Gallery",new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface arg0,int arg1) {
                Intent intent = new Intent();
                // call android default gallery
                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                // ******** code for crop image
                intent.putExtra("crop","true");
                intent.putExtra("aspectX",1);
                intent.putExtra("aspectY",1);
                intent.putExtra("outputX",200);
                intent.putExtra("outputY",200);
                intent.putExtra("noFaceDetection",true);
                try {
                    intent.putExtra("return-data",true);
                    startActivityForResult(Intent.createChooser(intent,"Complete action using"),Const.GALLERY_PICTURE);
                } catch (ActivityNotFoundException e) {
                    Log.e(LOG_TAG,"ActivityNotFoundException");
                }
            }
        });
        myAlertDialog.setNegativeButton("Camera",int arg1) {
                // call android default camera
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                intent.putExtra(MediaStore.EXTRA_OUTPUT,MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
                intent.putExtra("crop",true);
                    startActivityForResult(intent,Const.CAMERA_REQUEST);
                } catch (ActivityNotFoundException e) {
                    Log.e(LOG_TAG,"ActivityNotFoundException");
                }
            }
        });
        myAlertDialog.show();
    }

‘SherlockFragment’中的’onActivityResult’：

@Override
    public void onActivityResult(int requestCode,Intent data) {
        Log.d(LOG_TAG,"onActivityResult");
        super.onActivityResult(requestCode,data);
 
        if (resultCode != getSherlockActivity().RESULT_OK) {
            Log.e(LOG_TAG,"resultCode != RESULT_OK");
            return;
        }
 
        if (requestCode == Const.CAMERA_REQUEST) {
            Log.d(LOG_TAG,"requestCode == CAMERA_REQUEST");
            Bundle extras = data.getExtras();
            if (extras != null) {
                Log.d(LOG_TAG,"extras != null");
                Bitmap photo = extras.getParcelable("data");
                icon.setImageBitmap(photo);
            }
        }
 
        if (requestCode == Const.GALLERY_PICTURE) {
            Log.d(LOG_TAG,"requestCode == GALLERY_PICTURE");
            Bundle extras2 = data.getExtras();
            if (extras2 != null) {
                Log.d(LOG_TAG,"extras != null");
                Bitmap photo = extras2.getParcelable("data");
                icon.setImageBitmap(photo);
            }
        }
    }

UPDATE
当我调用相机活动时,我的主要活动调用’onSaveInstanceState’,然后调用’onRestoreInstanceState’.这是一个原因吗？
