该博客讨论了在Android应用中遇到的一个问题，即使用`android.support.v4.app.Fragment`时，代码需要`android.app.Fragment`。作者提供了详细的情景，展示了在请求相机权限时遇到的不兼容错误。解决方案可能涉及到迁移至AndroidX库或者适配旧版支持库的方法，以确保代码兼容并能正常运行。
I am using android.support.v4.app.Fragment. But, it's asking me to use android.app.Fragment that I can't. How can I resolve below issue:
import android.support.v4.app.Fragment;
public class CameraFragment extends Fragment implements View.OnClickListener, FragmentCompat.OnRequestPermissionsResultCallback {
private void requestCameraPermission() {
--> if (FragmentCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)) {
--> new ConfirmationDialog().show(getChildFragmentManager(), FRAGMENT_DIALOG);
} else {
FragmentCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA},
REQUEST_CAMERA_PERMISSION);
}
}
}
ERROR: Found: com.example.app.CameraFragment, required android.app.Fragment
public static class ConfirmationDialog extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final android.app.Fragment parent = getParentFragment();
return new AlertDialog.Builder(getActivity())
.setMessage(R.string.request_permission)
.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
FragmentCompat.requestPermissions(parent,
new String[]{Manifest.permission.CAMERA},
REQUEST_CAMERA_PERMISSION);
}
})
.setNegativeButton(android.R.string.cancel,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Activity activity = parent.getActivity();
if (activity != null) {
activity.finish();
}
}
})
.create();
}
}
