I was developing an App where i used Navigation Component, navigating by differents fragments.
In One of this fragment I would like to show a picture take by the camera of the phone, which is send from other fragment.
My problem is when I try to open the Fragment which take the photo, I get this error in that fragment.
I add the code of the fragment:
Capture.fragment
public class CaptureFragment extends Fragment {
private CaptureViewModel mViewModel;
private ImageButton btnCamara;
private ImageView mPhotoImageView;
public static final int REQUEST_CODE_TAKE_PHOTO = 0 /*1*/;
private String mCurrentPhotoPath;
private Uri photoURI;
private EditText Ettitulo;
public static CaptureFragment newInstance() {
return new CaptureFragment();
}
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container,
@Nullable Bundle savedInstanceState) {
Ettitulo = (EditText) container.findViewById(R.id.EtInstantanea);
mPhotoImageView = (ImageView) container.findViewById(R.id.imgCapture);
mPhotoImageView.setImageDrawable(null);
btnCamara = (ImageButton) container.findViewById(R.id.btnCapture);
btnCamara.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//1.Open the camera.
if (v == mPhotoImageView) {
if (ContextCompat.checkSelfPermission(getContext(),
Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(getContext(),
Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) getContext(),
Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
} else {
ActivityCompat.requestPermissions((Activity) getContext(),
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
225);
}
if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) getContext(),
Manifest.permission.CAMERA)) {
} else {
ActivityCompat.requestPermissions((Activity) getContext(),
new String[]{Manifest.permission.CAMERA},
226);
}
} else {
//Guarado de la foto en el almacenamiento interno
dispatchTakePictureIntent();
}
}
//2. Recover the photo and write into internal storage.
//TODO: Use AlerrtDiolog para solicitar nombre de la foto.
DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case DialogInterface.BUTTON_POSITIVE:
String titulo = Ettitulo.getText().toString();
// keep into DB.
Birddb bd = Birddb.getDatabase(getContext());
//Contructor con el titulo introducido por el usuario, y la url de la foto.
bd.birdDAO().insertBird(new BirdRoom(titulo, mCurrentPhotoPath));
//Send the Jornal,
Bundle bundle = new Bundle();
bundle.putString("edtValue", titulo);
bundle.putString("image", mCurrentPhotoPath);
//Swicth the () -> fragment
FragmentManager manager=getFragmentManager();
FragmentTransaction transaction=manager.beginTransaction();
JournalFragment jf = JournalFragment.newInstance();
jf.setArguments(bundle);
transaction.replace(container.getId(),jf);
transaction.commit();
break;
case DialogInterface.BUTTON_NEGATIVE:
//No button clicked
Toast.makeText(getContext(), "Foto NO añadida a su diario personal.", Toast.LENGTH_LONG).show();
break;
}
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
builder.setMessage("Are you sure?").setPositiveButton("Yes", dialogClickListener)
.setNegativeButton("No", dialogClickListener).show();
Intent intento1 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File foto = new File(getActivity().getExternalFilesDir(null), mCurrentPhotoPath);
intento1.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(foto));
startActivity(intento1);
//3. Set the photo into the ImageView,
Bitmap bitmap1 = BitmapFactory.decodeFile(getActivity().getExternalFilesDir(null)+"/"+Ettitulo.getText().toString());
Drawable d = new BitmapDrawable(getResources(), bitmap1);
mPhotoImageView.setImageDrawable(d);
//4. Ask if the user want to keep that pjoto into his jornal.
AlertDialog.Builder builder1 = new AlertDialog.Builder(getContext());
builder1.setMessage("¿Le gustaría guardar esta foto en su diario?");
builder1.setCancelable(true);
builder1.setPositiveButton(
"Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//Instancio la BBDD local..
Birddb db = Room.databaseBuilder(getContext(),
Birddb.class, "database-name").build();
//Añado el objeto Bird a la BBDD local.
BirdDAO birdDAO = db.birdDAO();
//List<Bird> users = userDao.getAll();
AsyncTask.execute(new Runnable() {
@Override
public void run() {
//Guardar Objeto Bird en la BBDD.
String descripcion = Ettitulo.getText().toString();
BirdRoom bird = new BirdRoom(descripcion, mCurrentPhotoPath);
Birddb.getDatabase(getContext()).birdDAO().insertBird(bird);
Toast.makeText(getContext(), "Ejemplar añadido correctamente a su diario", Toast.LENGTH_LONG).show();
}
});
}
});
builder1.setNegativeButton(
"No",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Toast.makeText(getContext(), "No se ha añadido la foto actual a su diario", Toast.LENGTH_LONG).show();
dialog.cancel();
}
});
AlertDialog alert11 = builder1.create();
alert11.show();
}
});
return inflater.inflate(R.layout.fragment_capture, container, false);
}
If you can help, take thanks for advance!
[EDIT]
After some advices I change the code like this I getting the same error:
mPhotoImageView = (ImageView) container.findViewById(R.id.imgCapture);
if(mPhotoImageView == null){
mPhotoImageView.setImageDrawable(ContextCompat.getDrawable(getActivity(), R.drawable.bird));
}
