android使用片段从相机或画廊获取照片[重复]

Question

我正在使用带有三个标签的FragmentPagerAdapter。每个选项卡都有多个fragments，在我请求从图库或相机获取照片的其中一个片段中。问题是托管选项卡的父 Activity 的 onActivityResult() 被调用，而不是 Fragment 的问题。帮助表示赞赏。

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case MEDIA_TYPE_IMAGE_FROM_GALLERY:
            if (resultCode == RESULT_OK) {
                Uri selectedImage = data.getData();
                String realPath = getImageRealPath(selectedImage);
                realPaths.add(realPath);
                Glide.with(mActivity)
                        .load(realPath)
                        .into(profile_imv);
            }
            break;
        case MEDIA_TYPE_IMAGE_BY_CAMERA:
            if (resultCode == RESULT_OK) {
                Uri selectedImage = data.getData();
                String realPath = getImageRealPath(selectedImage);
                realPaths.add(realPath);
                Glide.with(mActivity)
                        .load(realPath)
                        .into(profile_imv);
            }
            break;
    }
}

这是我如何为画廊和相机调用 Intent

public void choosePhotoFromGallary() {
    Intent galleryIntent = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

    startActivityForResult(galleryIntent, MEDIA_TYPE_IMAGE_FROM_GALLERY);
}

private void takePhotoFromCamera() {
    Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    if (intent.resolveActivity(mActivity.getPackageManager()) != null) {
        startActivityForResult(intent, MEDIA_TYPE_IMAGE_BY_CAMERA);
    }
}

这是MainACtivity onActivityResult() 代码

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Fragment fragment = getSupportFragmentManager().findFragmentByTag("USER_DETAILS");
    if (fragment != null) {
        fragment.onActivityResult(requestCode, resultCode, data);
    }
}

Answer 1

将getActivity().startActivityForResult(..) 更改为startActivityForResult(..) 这会将结果意图传递给片段的onActivityResult(..)

在这篇 SO 帖子 here 中进行了很好的解释

Answer 2

覆盖片段内的 onActiviyResult() 并在那里重写代码。
