我尝试创建自己的信息窗口,但运行时我遇到了这些错误:
错误:找不到符号变量LatLng
错误:找不到符号方法getPosition()
错误:无法从静态上下文引用非静态变量纬度
错误:无法从静态上下文引用非静态变量经度
错误:找不到符号类atLng
错误:任务':app:compileDebugJavaWithJavac'执行失败。编译失败;看到编译器 错误输出以获取详细信息。
这是我正在使用的代码:

有谁知道什么是错的?
感谢。
答案 0 :(得分:2)
您的代码:
LatLng = mMap1.getPosition();
tvLocality.setText(marker.getTitle());
tvLat.setText("Latitudine: " + LatLng.latitude);
tvLng.setText("Longitudine: " + LatLng.longitude);
tvSnippet.setText(marker.getSnippet());
你做错了什么
没有为LatLng声明变量
应该是 LatLng latlng = ....
mMap1将没有getposition()
你应该添加 marker.getPosition();
对于LatLng.latitude,您必须使用 latlng.latitude
修改后的代码
LatLng latlng= marker.getPosition();
tvLocality.setText(marker.getTitle());
tvLat.setText("Latitudine: " + latlng.latitude);
tvLng.setText("Longitudine: " + latlng.longitude);
tvSnippet.setText(marker.getSnippet());
的其他错误
atLng biss = new LatLng(45.758035, 21.227514);
mMap1.addMarker(new MarkerOptions()
.position(biserica)
.title("Church")
.snippet("gafhha")
.icon(BitmapDescriptorFactory. fromResource(R.drawable.marker)));
mMap1.moveCamera(CameraUpdateFactory.newLatLngZoom(biss, 14));
将其更改为
将 atLng 更改为 LatLng
将 biserica 更改为 biss
LatLng biss = new LatLng(45.758035, 21.227514);
mMap1.addMarker(new MarkerOptions()
.position(biss)
.title("Church")
.snippet("gafhha")
.icon(BitmapDescriptorFactory. fromResource(R.drawable.marker)));
mMap1.moveCamera(CameraUpdateFactory.newLatLngZoom(biss, 14));
