我正在尝试制作一个从相机拍摄高质量照片并显示在 imageview 中的程序/因此,如果我尝试在 Android 9 和 android 7 上运行代码,它可以正常工作/但是当我尝试将其放入 android 4.1.1 API 16 它不工作当我在拍照后单击 OK 时相机已经停止所以我认为拍照代码可以但问题是 (public void onActivityResult) 所以请帮帮我

public class MainActivity extends AppCompatActivity {

Intent intent;
    Uri fileUri, imageUri;
    Button btn_choose_image;
    ImageView imageView;
    Bitmap bitmap, decoded;
    public final int REQUEST_CAMERA = 1;
    public final int SELECT_FILE = 1;
    String currentImagePath = null;
    private static final int IMAGE_REQUEST = 1;
    int bitmap_size = 40; // image quality 1 - 100;
    int max_resolution_image = 800;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btn_choose_image = (Button) findViewById(R.id.btn_choose_image);
        imageView = (ImageView) findViewById(R.id.image_view);

        btn_choose_image.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                selectImage();
            }
        });
        // StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
        //  StrictMode.setVmPolicy(builder.build());
    }

    private void selectImage() {
        imageView.setImageResource(0);
        final CharSequence[] items = {"Take Photo", "Choose from Library",
                "Cancel"};

        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
        builder.setTitle("Add Photo!");
        builder.setIcon(R.mipmap.ic_launcher_round);
        builder.setItems(items, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int item) {
                if (items[item].equals("Take Photo")) {

                    Intent Inatent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    if (Inatent.resolveActivity(getPackageManager()) != null) {
                        File imageFile = null;
                        try {

                            e.printStackTrace();
                        }
                        if (imageFile != null) {
                            imageUri = FileProvider.getUriForFile(MainActivity.this, "com.example.fileprovider", imageFile);
                            Inatent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                            startActivityForResult(Inatent, REQUEST_CAMERA);
                        }
                    }
                } else if (items[item].equals("Choose from Library")) {
                    intent = new Intent();
                    intent.setType("image/*");
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_FILE);
                } else if (items[item].equals("Cancel")) {
                    dialog.dismiss();
                }
            }
        });
        builder.show();
    }



  @Override
    public void onActivityResult(int requestCode,int resultCode,Intent data){
        // Result code is RESULT_OK only if the user captures an Image
        if (resultCode == Activity.RESULT_OK)

                case REQUEST_CAMERA:
                    imageView.setImageURI(Uri.parse(currentImagePath));
                    break;
            }
    }


        private void setToImageView(Bitmap bmp) {

        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.JPEG, bitmap_size, bytes);
        decoded = BitmapFactory.decodeStream(new ByteArrayInputStream(bytes.toByteArray()));
        imageView.setImageBitmap(decoded);
    }

    // Untuk resize bitmap
    public Bitmap getResizedBitmap(Bitmap image, int maxSize) {
        int width = image.getWidth();
        int height = image.getHeight();

        float bitmapRatio = (float) width / (float) height;
        if (bitmapRatio > 1) {
            width = maxSize;
            height = (int) (width / bitmapRatio);
        } else {

        }

    }





    private File getImageFile() throws IOException {

        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageName="jpg_"+timeStamp+"_";
        File storagDir =getExternalFilesDir(Environment.DIRECTORY_PICTURES);
        File imaeFile=File.createTempFile(imageName,".jpg",storagDir);
        currentImagePath=imaeFile.getAbsolutePath();
        return imaeFile;
    }
}
