第一个问题。
当我在Android模拟器中构建应用程序而不是显示Google地图的地图时，它会显示空的灰色瓷砖。
我做过的事情：
我获取SHA1的命令如下：
./ keytool.exe -list -v -keystore /home/q/my_name/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
然后我获取sha1并粘贴到谷歌并添加分号和应用程序名称，所以：
E4:A ..... C38;com.example.myappname
好的，那我的代码：
主要活动：
package com.example.rest;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
public class Rest extends MapActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rest);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_rest, menu);
return true;
}
public void onProviderDisabled(String provider) {
Intent intent = new Intent( android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
}
清单：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.rest"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<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=".Rest"
android:label="@string/title_activity_rest" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
布局：
<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" >
<com.google.android.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="AIzaSyAdh38-k34RPi7aQ4ik6ExKKWI-wS-bDJA"
/>
</RelativeLayout>
重要的事情：
任何线索？问我关于我的问题你需要什么，我会回答。
（我编辑了应用名称和一些不能显示有关我姓名等的真实数据的事情。）

我在Linux上，但我正在使用位于winxp分区上的keytool.exe。我不知道这是否会引起问题。但keytool.exe给了我sha1没有问题，我只是提到它是重要的。
编辑：问题解决了！正确的答案是由FIDO ，只是滚动你的屏幕。
