Android：按钮不起作用，但代码未显示任何错误

Question

I'm trying to create a form to capture data, I need to access the camera to take pictures. My problem is when I try to call the camera with imagenButton , it's not working but the code doesn't show any error.

Here's my fragment to declare form:

public class EspecimenesInsertarFragment extends Fragment implements 
Response.Listener<JSONObject>, Response.ErrorListener {
private EspecimenesViewModel especimenesViewModel;
RequestQueue rq;
JsonRequest jrq;

final int COD_SELECCIONA=10;
final int COD_FOTO=20;

private static final int REQUEST_IMAGE_CAMERA=101;
private static final int REQUEST_PERMISSION_CAMERA=101;

Button btnGuardar, btnCancelar;
ImageButton btnCamara, btnGaleria;
ImageView imageView;
public static final int MY_DEFAULT_TIMEOUT = 50000;


public EspecimenesInsertarFragment() {
    // Required empty public constructor
}

public static EspecimenesInsertarFragment newInstance() { return new EspecimenesInsertarFragment();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    // Inflate the layout for this fragment

    View view;
    view = inflater.inflate(R.layout.fragment_colecciones_insertar, container, false);
    imageView = (ImageView)view.findViewById(R.id.imageView);
    btnCamara=(ImageButton) view.findViewById(R.id.tomarFoto);
    btnGuardar = (Button) view.findViewById(R.id.buttonIngresarEspecimenes);
    rq = Volley.newRequestQueue(getContext());


  /*  if(validaPermisos()){
        btnCamara.setEnabled(true);
    }else{
        btnCamara.setEnabled(false);
    } */

    if (ContextCompat.checkSelfPermission(getContext(), WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED &&
            ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(getActivity(), new String[]{WRITE_EXTERNAL_STORAGE,
                Manifest.permission.CAMERA}, 1000);
    }


    btnGuardar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            registrar_especimen("http://localhost/BIO-UES-APP/EspecimenesController.php");
        }
    });
static final int REQUEST_TAKE_PHOTO=1;

public void tomarFoto(View view){
    Intent takePictureInent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    Log.d("entra","");
    if(takePictureInent.resolveActivity(getActivity().getPackageManager())!= null){
        File photoFile=null;
        try {
            photoFile=createImageFile();
        }catch (IOException ex){

    }
        if(photoFile!=null){
        Uri photoUri=FileProvider.getUriForFile(getActivity(),"com.example.luvin.drawercero",photoFile);
        takePictureInent.putExtra(MediaStore.EXTRA_OUTPUT,photoUri);
        getActivity().startActivityForResult(takePictureInent,REQUEST_TAKE_PHOTO);
        }
    }
}

And this is my XML layout:

Logcat message when button is pressed:

com.example.luvin.drawercero D/ViewRootImpl@6731d38[MainActivity]: ViewPostIme pointer 1

To complete my question, I have the permissions in the manifest. I already tried to call the camera in another way, tried creating the method in the MainActivity to create the OnClick event in the XML Layout, but nothing works.
If anyone knows how to solve this issue please help.
Thanks.

You forgot to add the on click listener to your photo button. This should solve your problem:

btnCamara = view.findViewById(R.id.tomarFoto);
btnCamera.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        tomarFoto(v);
    }
});
