GoogleMap未显示

我正在尝试这个约4个小时，但没有发生。试图开发一个应用程序来显示谷歌地图中的特定位置。

以下代码：

GooglemapsActivity.java 

package com.example.gps2;

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import android.os.Bundle;

public class GooglemapsActivity extends MapActivity {

private MapView mapView;
private MapController mc;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mapView = (MapView) findViewById(R.id.mapView);
    mc = mapView.getController();

    String coordinates[] = {"30", "71"};
    double lat = Double.parseDouble(coordinates[0]);
    double lng = Double.parseDouble(coordinates[1]);

    GeoPoint p = new GeoPoint(
            (int) (lat * 1E6),
            (int) (lng * 1E6));

    mc.animateTo(p);
    mc.setZoom(7);
    mapView.invalidate();
}

@Override
protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    return false;
}
}

main.xml 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"

</LinearLayout>

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

我使用的是Google API 18（平台4.3）

我使用SHA1代码生成了android密钥“B5：EE：A3：80：7C：11：16：21：D7：EC：95：D1：FE：03：79：3D：4F：92： 2D：73; com.example.gps2"

我正在使用目标Google API 18的AVD。

毕竟，谷歌地图没有显示出来。只需使用网格获取屏幕。请建议我需要修复的地方才能使其正常工作。

4 个答案:

答案 0 :(得分：2)

您在应用程序中如何实施Google Maps API V2以及将许多内容与API V1实施相混淆时，一堆乱七八糟。

首先，要在一个活动中显示谷歌地图，你通常会使用MapFragment或SupportMapFragment（例如API < 11），所以你应该在你的xml布局中添加它活性：

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

接下来，您应inherit FramgnetActivity API V2反对MapActivity API V1，所以您应该这样做：

public class MapActivity extends FragmentActivity {
 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_layout);
    }
}

最后如前所述，您应该在清单文件中提供API密钥，而不是在xml文件中。所以把它放在application标记范围下的清单中：

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

和此：

<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="Your Google Maps API V2 Key" />

您可以在我撰写的关于此主题的博文中找到详细说明：

Google Maps API V2 Guide

答案 1 :(得分：0)

<permission
    android:name="your_package_name.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

尝试放置您的包裹名称....

答案 2 :(得分：0)

我建议您在https://developers.google.com/maps/documentation/android/start

时仔细按照设置进行操作

从我所看到的你的清单中，你错过了

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

和

<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="API_KEY"/>

并且推荐的布局是片段而不是MapView等。

答案 3 :(得分：0)

您正试图在AVD中获取地图，因此您可以参考this链接了解如何在模拟器中获取地图。
