我正在尝试在片段中启动相机，但片段中的 onActivityResult 无法解析 RESULT_OK。我该怎么办？
I am launching camera using:
我正在使用以下方法启动相机：
public static final int CAMERA_REQUEST_CODE = 1999;
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST_CODE);
get captured image using:
使用以下方法获取捕获的图像：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK) {
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
if (bitmap != null) {
}
}
}
and i want captured image in current fragment!
我想在当前片段中捕获图像！

RESULT_OKis constant of Activity class. In Activity class you can access directly but in other classes you need to write class name (Activity) also.
RESULT_OK是 Activity 类的常量。在 Activity 类中，您可以直接访问，但在其他类中，您也需要编写类名（Activity）。
Use Activity.RESULT_OKinstead of RESULT_OK.
使用Activity.RESULT_OK代替 RESULT_OK。
In your case it will be
在你的情况下，它将是
if (requestCode == CAMERA_REQUEST_CODE && resultCode == Activity.RESULT_OK) {

In fragment we must use getActivity()method as prefix with RESULT_OK.
在片段中，我们必须使用getActivity()方法作为前缀RESULT_OK。
In your case it will be:-
在您的情况下，它将是：-
if (requestCode == CAMERA_REQUEST_CODE && resultCode == getActivity().RESULT_OK)

Alternatively you can add import static android.app.Activity.RESULT_OK;and use it in your case like if (requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK) {..}
或者，您可以import static android.app.Activity.RESULT_OK;在您的情况下添加和使用它，例如if (requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK) {..}
