如何仅以片段形式打开相机 [英] How to open camera ONLY in a fragment

问题描述

以下代码将打开相机，但会覆盖整个屏幕，并在捕获图像后返回到片段。没有单击图像的迹象。 （图片已安全地保存在图库中。我只想在片段部分中打开相机。我从此处。我不知道它在做什么，只是删除了'viewHolder'（try（）的第4行），并在代码的顶部声明了URI变量。

我还尝试了其他答案，例如此，但是它们与我一样复杂在API 19上开发。

Following code opens camera but covers complete screen, and after capturing image it returns to the fragment No signs of clicked image. ( image is safely saved in gallery. I want to open camera ONLY IN FRAGMENT part. I have copied the code from here. I just removed 'viewHolder' (4rth line of try()) as I don't know what it was doing. and declared URI variable at top in my code.
I also have tried other answers like this but they are complicated as I am developing on API 19.

//my declared variables 
 private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 1888;
    Button button;
    ImageView imageView;
    Uri imageUri;


@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
        File photo = new File(Environment.getExternalStorageDirectory(),  "Pic.jpg");
        intent.putExtra(MediaStore.EXTRA_OUTPUT,
                Uri.fromFile(photo));
        imageUri = Uri.fromFile(photo);
        getActivity().startActivityForResult(intent, 100);


        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_scan, container, false);
    }


@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case 100:
                if (resultCode == Activity.RESULT_OK) {
                    Uri selectedImage = imageUri;
                    getActivity().getContentResolver().notifyChange(selectedImage, null);
                    ContentResolver cr = getActivity().getContentResolver();
                    Bitmap bitmap;
                    try {
                        bitmap = android.provider.MediaStore.Images.Media
                                .getBitmap(cr, selectedImage);

                        imageView.setImageBitmap(bitmap);
                        Toast.makeText(getActivity(), selectedImage.toString(),
                                Toast.LENGTH_LONG).show();
                    } catch (Exception e) {
                        Toast.makeText(getActivity(), "Failed to load", Toast.LENGTH_SHORT)
                                .show();
                        Log.e("Camera", e.toString());
                    }
                }
        }
    }

推荐答案

以下代码打开了摄像头，但覆盖了整个屏幕

Following code opens camera but covers complete screen

可以。您正在启动第三方相机应用程序，这些应用程序通常会占据前台。

Sure. You are launching a third-party camera app, and those usually take over the foreground.

我只想在片段部分打开相机。

I want to open camera ONLY IN FRAGMENT part.

使用 android.hardware.Camera 从头开始编写自己的相机代码和/或 android.hardware.camera2。* 一组类。您无法将第三方相机应用程序启动成片段。

Write your own camera code from scratch, using android.hardware.Camera and/or the android.hardware.camera2.* set of classes. You cannot launch a third-party camera app into a fragment.
