這是我的android清單文件。

這是我的map.xml文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<fragment
    android:id="@+id/restaurant_map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />

這是我的restaurantmap.java活動。

 package sp.com;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class RestaurantMap extends Activity {
    // static final LatLng RESTAURANT = new LatLng(1.334611, 103.746836);
    // static final LatLng KIEL = new LatLng(1.333522, 103.740286);
    private GoogleMap map;
    private double lat;
    private double lon;
    private String restaurantName;
    private double myLat;
    private double myLon;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);

        lat = getIntent().getDoubleExtra("LATITUDE", 0);
        lon = getIntent().getDoubleExtra("LONGITUDE", 0);
        restaurantName = getIntent().getStringExtra("NAME");
        myLat = getIntent().getDoubleExtra("MYLATITUDE", 0);
        myLon = getIntent().getDoubleExtra("MYLONGITUDE", 0);

        LatLng RESTAURANT = new LatLng(lat, lon);
        LatLng ME = new LatLng(myLat, myLon);

        map = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.restaurant_map)).getMap();
        Marker restaurant = map.addMarker(new MarkerOptions().position(
                RESTAURANT).title(restaurantName));
        Marker me = map.addMarker(new MarkerOptions()
                .position(ME)
                .title("ME")
                .snippet("My Location")
                .icon(BitmapDescriptorFactory
                        .fromResource(R.drawable.ic_launcher)));

        // Move the camera instantly to restaurant with a zoom of 15.
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(RESTAURANT, 15));

        // Zoom in, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
    }

}

誰能幫助我找出我做錯了什么？ 我仍然是Java的初學者，非常感謝您的幫助。 干杯！

Answer 1

這是繼承問題。 如果您的xml中有標簽，則您的活動應擴展FragmentActivity或從FragmentActivity擴展的任何其他活動，例如actionBarActivity。

您也沒有Google Play服務所需的元數據標簽。 它應該是應用程序標記的直接子代。

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

Answer 2

用它代替您的元數據，我認為是android：name造成了問題。 不確定，但是請嘗試一次，也許會有用。 我還為gps.add添加了一個標簽。

<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="--- the key ---" />

Answer 3

您在這里有錯字：

<meta-data
    android:name="com.google.android.maps.v2.API Key"
    android:value="--- the key ---" />

它應該是：

    android:name="com.google.android.maps.v2.API_KEY"

另外，請勿在公共論壇上發布您的API密鑰！ 應該是私人的。
