拍照后相机不return到主activity

Question

当主要 activity 启动时，它会直接启动 MediaStore.ACTION_IMAGE_CAPTURE 的意图我实现了 onActivityResult 方法，但是当我拍照时它没有 return 返回主 activity，而是保留在相机应用程序中

这是代码：

final int REQUEST_TAKE_IMAGE = 1;

    ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        imageView = findViewById(R.id.imageView);
    }

    @Override
    protected void onStart() {
        super.onStart();
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if(intent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(intent, REQUEST_TAKE_IMAGE);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if(requestCode == REQUEST_TAKE_IMAGE){
            if(resultCode == RESULT_OK){
                assert data != null;
                Bundle extras = data.getExtras();
                assert extras != null;
                Bitmap bitmap = (Bitmap) extras.get("data");
                imageView.setImageBitmap(bitmap);
            }
        }
    }

尝试将 Intent 启动转移到按钮点击侦听器，我猜发生的事情是每当你的 activity 启动时，它会将人带回相机应用程序，因为 Intent 在启动时启动并且 activity 每次你试图将它带到前台时都会使用这个回调，即选择一个并期望它把你带回 activity.
