public class ModelClass {

@SerializedName("longi")
public String longitudeServer;

@SerializedName("lati")
public String latitudeServer;

@SerializedName("uniqueid")
public String uniqueidSserver;

public ModelClass(){
    // blank constructor is required
}

public String getLongitude(){
    return longitudeServer;
}


public String getLatitude(){
    return latitudeServer;
}


public String getUniqueId(){
    return uniqueidSserver;

//... More setter and getter here

}

1：-problem是跳转当前指针。

公共类中的

creat方法addMarker（）MainActivity扩展了AppCompatActivity

private void addMarker() {
    try {
        //ArrayList list = new ArrayList<>();
        //TODO: remove previus markers
        if (marker != null) {
            mMap.clear();
            Toast.makeText(getApplicationContext(), "Remove", Toast.LENGTH_LONG).show();

        }
        for (LatLng object : latLngList)

            marker = mMap.addMarker(new MarkerOptions().title("User Name").position(object).icon(BitmapDescriptorFactory.fromResource(R.drawable.female4)));

        System.out.println(marker.getPosition() + "  Marker position.......");
    } catch (Exception e) {
        Toast.makeText(MainActivity.this, "Error ", Toast.LENGTH_LONG).show();
        // mMap.clear();
    }
}

并在

中调用它

 if (servicesOK()) {
        setContentView(R.layout.activity_map);

        if (initMap()) {
            //  gotoLocation(SEATTLE_LAT, SEATTLE_LNG, 15);

            mLocationClient = new GoogleApiClient.Builder(this)
                    .addApi(LocationServices.API)
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .build();

            mLocationClient.connect();


            mMap.setMyLocationEnabled(true);
        } else {
            Toast.makeText(this, "Map not connected!", Toast.LENGTH_SHORT).show();
        }

        addMarker();

    } else {
        setContentView(R.layout.activity_main);
    }

在OnPostExecute中

 protected void onPostExecute(Boolean result) {
        // dialog.cancel();
        // adapter.notifyDataSetChanged();
        Toast.makeText(getApplicationContext(), "Receicve data from server", Toast.LENGTH_LONG).show();

        if (result == false) {
            Toast.makeText(getApplicationContext(), "Unable to fetch data from server", Toast.LENGTH_LONG).show();

        }
//            try {
//                //ArrayList list = new ArrayList<>();
//                //TODO: remove previus markers
//                if (marker != null) {
//                    mMap.clear();
//                    Toast.makeText(getApplicationContext(), "Remove",     Toast.LENGTH_LONG).show();
//
//                }
//                for (LatLng object : latLngList)
//
//                    marker = mMap.addMarker(new MarkerOptions().title("User Name").position(object).icon(BitmapDescriptorFactory.fromResource(R.drawable.female4)));
//
//                System.out.println(marker.getPosition() + "  Marker position.......");
//            } catch (Exception e) {
//                Toast.makeText(MainActivity.this, "Error ", Toast.LENGTH_LONG).show();
//                // mMap.clear();
//            }

    }

}

Answer 2

虚拟使用SerializedName

    @SerializedName("Savings")
    private String savings;

您需要添加

编译com.google.code.gson：gson：2.3.1＆＃39;

build.gradle中的内部依赖项

我想用@SerializedName GSON对象实现此代码
