谷歌地图未加载

Question

我正在使用地图并尝试加载 Googlemap，但是当我运行应用程序时它没有加载。它只是显示空网格而不是地图。 请帮我... 主要活动 包 com.mamun.maptest;

import android.os.Bundle;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import com.google.android.maps.GeoPoint;

public class MainActivity extends MapActivity {
    private MapView mapView;
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mapView = (MapView) findViewById(R.id.mapview1);
    }

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



}

*xml文件

Answer 1

Google 地图 API v1 已弃用。您应该使用地图 api v2。

要遵循的所有步骤@

https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2

你需要参考google play services library project。

您需要来自 google api 控制台的 api，并且您应该为 android @启用地图

https://code.google.com/apis/console‎

在 xml 中有以下内容

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.SupportMapFragment"/>

然后

public class MainActivity extends FragmentActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }
