Question

我想用谷歌地图标记标记我的地址（编辑文本）。

我创建了一个简单的表单，但是当我填充地址并在同一个地方放一个标记时，我想在地图上标记它。

我正在获取地址字段的纬度和经度然后我会使用标记来固定它但我在初始阶段只有问题（请考虑我作为Android中的菜鸟，因为我已经开始几天了）

               addMarker(latLng);
            }
        });


private void addMarker(LatLng latLng){
String text=editText.getText().toString();
Marker marker = mGoogleMap.addMarker(new MarkerOptions()
            .position(latLng)
            .title(text));
