Android的谷歌地图没有加载在活动小版面 [英] Android Google Map not loading in activity small layout

问题描述

在我的应用程序正在使用中的活动地图视图底部side.but地图不加载properly.after点击地图上2-3倍的显示效果清晰地图和放大器。在同一张地图，如果负载在众目睽睽它加载清楚。 如何解决这个？

截屏是 -

 ＆LT; com.google.android.gms.maps.MapView
            机器人：ID =@ + ID /图
            机器人：layout_width =FILL_PARENT
            机器人：layout_height =200dp
            机器人：layout_margin =10dp/＆GT;
 

Java的code -

 尝试{
            MapsInitializer.initialize（getApplicationContext（））;
        }赶上（GooglePlayServicesNotAvailableException E）{
            // TODO自动生成的catch块
            e.printStackTrace（）;
        }

        开关（GooglePlayServicesUtil.isGooglePlayServicesAvailable（getApplicationContext（）））
        {
        案例ConnectionResult.SUCCESS：

            图形页面=（图形页面）findViewById（R.id.map）;
            mapView.onCreate（savedInstanceState）;
            //获取从图形页面来使用GoogleMap并执行初始化的东西
            如果（图形页面！= NULL）
            {
                地图= mapView.getMap（）;
                map.getUiSettings（）setMyLocationButtonEnabled（假）。
                map.setMyLocationEnabled（真正的）;
                CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom（locationPosition，10）;
                map.animateCamera（cameraUpdate）;
                map.setMapType（GoogleMap.MAP_TYPE_NORMAL）;
            }
            打破;
        案例ConnectionResult.SERVICE_MISSING：

            打破;
        案例ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED：

            打破;
        默认：Toast.makeText（getApplicationContext（），GooglePlayServicesUtil.isGooglePlayServicesAvailable（getApplicationContext（）），Toast.LENGTH_SHORT）.show（）;
        }

        CameraPosition cameraPosition =新CameraPosition.Builder（）
        .TARGET（locationPosition）.zoom（10）.bearing（0）//设置摄像头向东的方向
        .tilt（70）//摄像机的倾斜设置为30度
        。建立（）; //创建从制造商一个CameraPosition
        map.setBuildingsEnabled（真正的）;
        map.setMyLocationEnabled（真正的）;
        map.setMapType（GoogleMap.MAP_TYPE_NORMAL）;
        map.animateCamera（CameraUpdateFactory.newCameraPosition（cameraPosition））;
        map.addMarker（新MarkerOptions（）.position（locationPosition）.icon（BitmapDesc​​riptorFactory.fromResource（R.drawable.icon_marker）））;
 

解决方案

我（我坚持用工作，即使它是pcated在这一点上德$ P $的MapView）一个非常类似的问题。 这是我的问题，也是我的回答：<一href="http://stackoverflow.com/questions/32908988/android-map-loading-very-slow-not-loading-at-all-in-started-activity-until-click">Android地图加载速度很慢/没有加载在所有在活动开始之前，点击它

您需要实现以下方法： OnResume（）;将OnPause（）;的onDestroy（）; onLowMemory（）;

希望它帮助。

In my application i'm using map view in activity at bottom side.but map doesn't load properly.after clicking on map 2-3 time its shows clear map.& when same map if load in full view it's loading clearly. What is the solution for this?

screen shot is-

<com.google.android.gms.maps.MapView
            android:id="@+id/map"
            android:layout_width="fill_parent"
            android:layout_height="200dp"
            android:layout_margin="10dp" />

java code-

try {
            MapsInitializer.initialize(getApplicationContext());
        } catch (GooglePlayServicesNotAvailableException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        switch (GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext()) )
        {
        case ConnectionResult.SUCCESS:

            mapView = (MapView)findViewById(R.id.map);
            mapView.onCreate(savedInstanceState);
            // Gets to GoogleMap from the MapView and does initialization stuff
            if(mapView!=null)
            {
                map = mapView.getMap();
                map.getUiSettings().setMyLocationButtonEnabled(false);
                map.setMyLocationEnabled(true);
                CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(locationPosition, 10);
                map.animateCamera(cameraUpdate);
                map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            }
            break;
        case ConnectionResult.SERVICE_MISSING: 

            break;
        case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED: 

            break;
        default: Toast.makeText(getApplicationContext(), GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext()), Toast.LENGTH_SHORT).show();
        }

        CameraPosition cameraPosition = new CameraPosition.Builder()
        .target(locationPosition).zoom(10).bearing(0) // Sets the orientation of the camera to east
        .tilt(70)    // Sets the tilt of the camera to 30 degrees
        .build();    // Creates a CameraPosition from the builder
        map.setBuildingsEnabled(true);
        map.setMyLocationEnabled(true);
        map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
        map.addMarker(new MarkerOptions() .position(locationPosition).icon(BitmapDescriptorFactory.fromResource(R.drawable.icon_marker)));

解决方案

I had a very similar problem(I insisted working with the MapView even though it is deprecated at this point). Here it is my issue and also my answer: Android Map loading very slow/not loading at all in started activity until clicking on it

You need to implement the following methods: OnResume(); OnPause(); onDestroy(); onLowMemory();

Hope it helps.
