添加全局变量

public static final int PHOTO_REQUEST_CAREMA = 2022;
public static final String PICTURE_FILE = "temp.jpg";

调用相机并存储

Intent camintent = new Intent("android.media.action.IMAGE_CAPTURE");
Uri imageUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), PICTURE_FILE));
camintent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
// 开启一个带有返回值的Activity，请求码为PHOTO_REQUEST_CAREMA
startActivityForResult(camintent, PHOTO_REQUEST_CAREMA);

回调


    // 回调
    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode != RESULT_OK) {
            return;
        }
        if (requestCode == PHOTO_REQUEST_CAREMA) {// 拍照
            Bitmap bmp = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory()
                    + "/" + PICTURE_FILE);
            imgOcr.setImageBitmap(bmp);
        }
    }
