Mening joylashuvim qatlami
"Mening joylashuvim" qatlami va shu nomdagi tugma foydalanuvchilarga xaritada hozirgi manzilini ko'rish imkonini beradi. "Mening joylashuvim" qatlamini yoqish uchun mMap.setMyLocationEnabled () usulini chaqiring.
Eslatma. "Mening joylashuvim" qatlamini yoqishdan oldin, joylashuv ma'lumotlariga kirishga dinamik ruxsatingiz borligiga ishonch hosil qiling.
"Mening joylashuvim" qatlamini ishlatishning oddiy misoli:

Agar "Mening joylashuvim" qatlami yoqilgan bo'lsa, ekranning o'ng yuqori burchagida tegishli tugma ko'rsatiladi. Bu tugma bosilganda kamera, agar ma'lum bo'lsa, xaritani qurilmaning joriy joylashgan joyiga yo'naltiradi. Xaritada, agar qurilma harakatsiz bo'lsa, joylashuvi kichik ko'k nuqta bilan ko'rsatiladi yoki agar qurilma harakatda bo'lsa, chevron belgisi bilan ko'rsatiladi.
Quyidagi skrinshotda siz yuqori o'ng burchakda "Mening joylashuvim" tugmachasini va xaritaning markazida ko'k nuqtani ko'rishingiz mumkin.
