谷歌静态地图挂起时载入

问题描述：

map = (ImageView) contentView.findViewById(R.id.map); 

........... 
.......... 

    private void setMap(){ 
      final String STATIC_MAP_API_ENDPOINT = "http://maps.google.com/maps/api/staticmap?center=" + Lat + "," + Long + "&zoom=13&size=640x400&markers=color:red%7C" + Lat + "," + Long; 

      AsyncTask<Void, Void, Bitmap> setImageFromUrl = new AsyncTask<Void, Void, Bitmap>() { 
       @Override 
       protected Bitmap doInBackground(Void... params) { 
        Bitmap bmp = null; 
        HttpClient httpclient = new DefaultHttpClient(); 
        HttpGet request = new HttpGet(STATIC_MAP_API_ENDPOINT); 

        InputStream in = null; 
        try { 
         in = httpclient.execute(request).getEntity().getContent(); 
         bmp = BitmapFactory.decodeStream(in);

     }

我正在设置地图ImageView。现在标题说，当网络缓慢时，整个活动在加载地图时挂起。任何解决方案

检查下面给出的解决方案。 –

嗨，感谢您的回答，但是我正在使用地图进行其他布局内部活动。所以地图应该在其他布局的活动中。其他解决方案？ –

对不起，我没有得到你所问的。你能用代码来澄清更多吗？ –

答

尝试将Google地图加载到活动中的片段中。在此之后不会挂断您的设备。

让你activity_maps.xml是：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" 
android:weightSum="1"> 

     <fragment xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:map="http://schemas.android.com/apk/res-auto" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:id="@+id/map" 
     android:name="com.google.android.gms.maps.SupportMapFragment" 
     android:layout_height="wrap_content" 
     android:layout_width="match_parent" 
     tools:context=".MapsActivity" 
     android:layout_centerHorizontal="true" 
     android:layout_alignParentBottom="true"/> 

<RelativeLayout/>

在这里，你有你的活性的片段。您可以根据需要调整图像的大小。

Java代码（MapsActivity.java）：

@Override 
public void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 

    setContentView(R.layout.activity_maps); 

    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1); 

    // Obtain the SupportMapFragment and get notified when the map is ready to be used. 

    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); 

    mapFragment.getMapAsync(this); 
} 

@Override 
public void onMapReady(GoogleMap googleMap) { 

    mMap = googleMap; 


    mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) 
      == PackageManager.PERMISSION_GRANTED) { 

     mMap.setMyLocationEnabled(true); 

    } 
    mMap.setMyLocationEnabled(true); 

    mMap.getUiSettings().setCompassEnabled(true); 

    mMap.getUiSettings().setZoomControlsEnabled(true); 

    mMap.getUiSettings().setMyLocationButtonEnabled(true); 

    mMap.getUiSettings().setMapToolbarEnabled(true); 

    points = new ArrayList<LatLng>(); 

    // Determining Current Location 

    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); 

    Criteria criteria = new Criteria(); 

    String provider = locationManager.getBestProvider(criteria, true); 

    Location location = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER); 

    if (location != null) { 

     latitude = location.getLatitude(); // get current latitude 

     longitude = location.getLongitude(); // get current longitude 

     myPosition = new LatLng(latitude, longitude); 

     LatLng coordinate = new LatLng(latitude, longitude); 

     CameraUpdate yourLocation = CameraUpdateFactory.newLatLngZoom(coordinate,15); 

     mMap.animateCamera(yourLocation); 

    } 
}

这样就可以实现在片段的谷歌地图，它不会挂起。

另外不要忘记在清单中添加权限。

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 
<uses-permission android:name="com.avl.pucc.rajasthan.permission.MAPS_RECEIVE" /> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="com.google.android.maps" /> 
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
