Question

我必须在我的应用程序中加载地图。我已经完成了所有工作.1.Getting key和all ..但现在它显示为普通网格..地图未加载...请帮助我..

我的活动代码：

public class Mapcctivity extends MapActivity {
    private MapView mMapView = null;  
     private MapController mc = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_mapcctivity);

        GeoPoint gPoint = new GeoPoint(19240000,-99120000);

        mMapView = (MapView) findViewById(R.id.mView);
        mMapView.setSatellite(true);
        mMapView.setBuiltInZoomControls(true);

        mc = mMapView.getController();
        mc.setZoom(15);
        mc.setCenter(gPoint);
    }

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


}

我的布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >



    <com.google.android.maps.MapView
  android:id="@+id/mView"
  android:layout_width="fill_parent" 
  android:layout_height="375dp"
  android:padding="5dp"
  android:enabled="true" 
  android:clickable="true" 
  android:apiKey="My key" />

</LinearLayout>

清单文件：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.map"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="7"
        android:targetSdkVersion="15" />

    <uses-permission android:name="android.permission.WRITE_GSERVICES" />

    <application



        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <uses-library android:name="com.google.android.maps" />
        <activity
            android:name=".Mapcctivity"
            android:label="@string/title_activity_mapcctivity" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

    </application>

</manifest>

当Map加载时，我的logcat是这样的：

Answer 1

你把密码传给了吗？

android:apiKey="My key"

另请注意，您的签名应用程序证书仅在导出时使用。当你在eclipse app中按“run”时，你的“开发证书”就会签名。由于API密钥绑定到开发人员证书，您必须使用自己的密钥对应用程序进行签名，或者将API密钥更改为为您的开发密钥生成的密钥。

在Android中加载地图时会显示Plain Grid
