我有一个随机纬度和经度点的列表,我正在他们之间绘制一条路线.我的问题是如何在谷歌地图中绑定这条路线,我在实用方法下面做了

public static void drawRouteIntoMap(final List<? extends MapHelper> position, final GoogleMap googleMap) {
    /*List<MapHelper> position = new ArrayList<MapHelper>();
    for (int i = lastPosition; i < maps.size(); i++) {
        position.add(maps.get(i));
    }*/
    if (position.size() > 0 && Validator.isNotNull(googleMap)) {
        googleMap.clear();
        List<PolylineOptions> polylineOptionses = new ArrayList<PolylineOptions>();
        PolylineOptions option = null;
        Boolean lastPause = null;
        for (MapHelper map : position) {
            if (map.isPause()) {
                if (Validator.isNull(lastPause) || !lastPause) {
                    option = new PolylineOptions().width(5).color(Color.rgb(255, 0, 155)).geodesic(true);
                    polylineOptionses.add(option);
                }
                option.add(new LatLng(map.getLatitude(), map.getLongitude()));
            } else {
                if …

下面是我使用FireBaseJobDispatcher开始工作的演示代码.

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(this));
        Job job=createJob(dispatcher);
        dispatcher.schedule(job);


    }

    public static Job createJob(FirebaseJobDispatcher dispatcher){
        Job job = dispatcher.newJobBuilder()
                // persist the task across boots
                .setLifetime(Lifetime.FOREVER)
                // Call this service when the criteria are met.
                .setService(ScheduledJobService.class)
                // unique id of the task
                .setTag("LocationJob")
                // We are mentioning that the job is not periodic.
                .setRecurring(true)
                // Run between 30 - 60 seconds from now.
                .setTrigger(Trigger.executionWindow(10,20))
                //Run …

我正在使用排球库进行网络服务调用.我创建了一个通用类,用于调用所有Web服务并从那里进行服务调用,并为成功和错误响应提供匿名侦听器.

但是当我使用泄漏金丝雀时,它显示出与上下文相关的内存泄漏.以下是我的代码片段:

public void sendRequest(final int url, final Context context, final ResponseListener responseListener, final Map<String, String> params) {
    StringRequest stringRequest;
    if (isNetworkAvailable(context)) {

      stringRequest = new StringRequest(methodType, actualURL + appendUrl, new Listener<String>() {
            @Override
            public void onResponse(String response) {
                dismissProgressDialog(context);
                try {
                    (responseListener).onResponse(url, response);
                } catch (JsonSyntaxException e) {
                    // Util.showToast(context, context.getResources().getString(R.string.error));
                    Crashlytics.logException(e);
                }
            }

        }, new ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                // Util.showToast(context,context.getString(R.string.error));

                dismissProgressDialog(context);
                if (error instanceof NetworkError) {
                     Util.showToast(context, context.getResources().getString(R.string.network_error));
                } else if (error instanceof …

我正在使用谷歌地图精简模式版本,我正在联想K50a40上绘制多边形线和标记我收到以下错误

当我在设备上加载谷歌地图时,我有时会收到下面的屏幕.如第二次加载,如下所示. 否则它完全像正常的谷歌地图与路线我使用SupportmapFragment并获得googleMap对象.

 supportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map_view_fragment);

下面是在activity/fragment中显示map的代码

public static void drawRouteIntoMap(final List<? extends MapHelper> position, final GoogleMap googleMap) {
        /*List<MapHelper> position = new ArrayList<MapHelper>();
        for (int i = lastPosition; i < maps.size(); i++) {
            position.add(maps.get(i));
        }*/
        final LatLngBounds.Builder mapBounds = new LatLngBounds.Builder();
        if (position.size() > 0 && Validator.isNotNull(googleMap)) {
            googleMap.clear();
            List<PolylineOptions> polylineOptionses = new ArrayList<PolylineOptions>();
            PolylineOptions option = null;
            Boolean lastPause = null;
            for (MapHelper map : position) {
                if (map.isPause()) {
                    if (Validator.isNull(lastPause) || !lastPause) {
                        option = new …

下面是我用来绘制路线的代码.每当用户暂停锻炼时,我想将此路径显示为粉红色折线.因此,我创建了自己的接口,MapHelper并将一个布尔值作为isPause和lastPause.当用户保存他/她的锻炼时,我将所有路线点保存为阵列,在典型列表中,我将这些地图显示为Feed,为此我使用的是精简模式版Googlemap.下面是我的适配器类

Adapter.java

public class FeedsAdpter extends RecyclerView.Adapter<FeedsAdpter.MyViewHolder> {
    private LayoutInflater inflater;
    private Context context;
    private FeedsFragment feedsFragment;
    RoundedTransFormation transFormation;
    private ArrayList<FeedsDto> allFeedsList = new ArrayList<FeedsDto>();


    public FeedsAdpter(Context context, FeedsFragment feedsFragment) {
        this.context = context;
        this.feedsFragment = feedsFragment;
        transFormation=new RoundedTransFormation(3, 15,Color.WHITE);
        inflater = LayoutInflater.from(context);
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = inflater.inflate(R.layout.item_feeds, parent, false);
        MyViewHolder holder = new MyViewHolder(view);
        return holder;
    }


    @Override
    public void onViewRecycled(MyViewHolder holder) {
        super.onViewRecycled(holder);
        if(Validator.isNotNull(holder.mapView.getMap())) …
