如何在谷歌地图android上添加标记？

implementation 'com.google.android.gms:play-services-maps:17.0.1'

<uses-permission android:name="android.permission.INTERNET" />

<!-- 添加以下meta-data标签 -->
<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="YOUR_API_KEY" />

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

// 初始化地图
MapView mapView = findViewById(R.id.mapView);
mapView.onCreate(savedInstanceState);
mapView.getMapAsync(new OnMapReadyCallback() {
    @Override
    public void onMapReady(GoogleMap googleMap) {
        // 在地图上添加标记
        LatLng location = new LatLng(latitude, longitude);
        MarkerOptions markerOptions = new MarkerOptions()
                .position(location)
                .title("标记标题")
                .snippet("标记描述");
        googleMap.addMarker(markerOptions);
        
        // 将地图移动到标记位置
        googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(location, 15));
    }
});

// 在Activity的生命周期方法中添加以下代码
@Override
protected void onResume() {
    super.onResume();
    mapView.onResume();
}

@Override
protected void onPause() {
    super.onPause();
    mapView.onPause();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    mapView.onDestroy();
}

@Override
public void onLowMemory() {
    super.onLowMemory();
    mapView.onLowMemory();
}
