问题描述
您好我开发一个地图视图我试着按以下方式
我通过点击一个按钮]创建的意图。新增的权限和库
。我创建了一个覆盖项目。
。我模拟器的目标是为GoogleApi 2.3.3。我的MapView键obdained和asigned到mapview.xml
Hello I am developing a map view I tried to following way I created an "Intent" by clicking on a button]. Added permission and library . I created an overlay item. .My Emulator is targeted as GoogleApi 2.3.3 .My MapView key is obdained and asigned into mapview.xml
我看到的地图与底部和地图视图CONTROLER一个谷歌的标志：这里是我的code
I am seeing the map with a google logo at bottom and map view controler: here is my code
MapView.xml
MapView.xml

MapViewActivity.java
MapViewActivity.java
public class MapviewActivity extends MapActivity
{ private static double lat = 35.952967; // Temporary test values for lat/long

mapView.setBuiltInZoomControls(true);
mapView.setSatellite(true);
mapControl = mapView.getController();
mapControl.setZoom(12); // Zoon 1 is world view
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
0, new GeoUpdateHandler());
myLocationOverlay = new MyLocationOverlay(this, mapView);

public class GeoUpdateHandler implements LocationListener {

}
// Required method since class extends MapActivity

这是我的MyOverlays.java
here is my MyOverlays.java
public class MyOverlays extends ItemizedOverlay<OverlayItem> {
private static int maxNum = 5;
private OverlayItem overlays[] = new OverlayItem[maxNum];
private int index = 0;
private boolean full = false;
private Context context;

public MyOverlays(Context context, Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
this.context = context;
}
@Override
protected OverlayItem createItem(int i) {
return overlays[i];
}
@Override
public int size() {
if (full) {
return overlays.length;
} else {
return index;
}
}
public void addOverlay(OverlayItem overlay) {
if (previousoverlay != null) {
if (index < maxNum) {
overlays[index] = previousoverlay;
} else {
index = 0;
full = true;
overlays[index] = previousoverlay;
}
index++;
populate();
}
this.previousoverlay = overlay;
}
protected boolean onTap(int index) {
OverlayItem overlayItem = overlays[index];
Builder builder = new AlertDialog.Builder(context);
builder.setMessage("This will end the activity");
builder.setCancelable(true);
builder.setPositiveButton("I agree", new OkOnClickListener());
builder.setNegativeButton("No, no", new CancelOnClickListener());
AlertDialog dialog = builder.create();
dialog.show();
return true;
};
private final class CancelOnClickListener implements
DialogInterface.OnClickListener {
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(context, "You clicked yes", Toast.LENGTH_LONG)
.show();
}
}
private final class OkOnClickListener implements
DialogInterface.OnClickListener {
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(context, "You clicked no", Toast.LENGTH_LONG).show();
}
}
}
我Android.manifest
My Android.manifest
<uses-sdk android:minSdkVersion="10" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"/>
<application
android:icon="@drawable/drive_eat_icon"
android:label="@string/app_name" android:allowClearUserData="true" android:debuggable="true">
<activity

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".DriveatmapActivity"></activity>
<activity android:name=".MapviewActivity"></activity>
<activity android:name=".FoodjointListActivity"></activity>
<activity android:name=".SubmitFormActivity"></activity>
<activity android:name=".MyOverlays"/>
<uses-library android:required="true" android:name="com.google.android.maps"></uses-library>
</application>
请建议做什么。如果您需要任何code，请让我知道。
我看到了谷歌地图只用灰瓦。
please suggest what to do . if you need any code please let me know. I am seeing the google map with only grey tiles.
推荐答案
使用它来获取有效的API密钥 -
Use it to get the Valid API key--
这是确切的路径 -
that is the exact path--
keytool -list -keystore "C:\Users\XYZ\.android\debug.keystore"
对于总路径的命令提示符得到MD5 fingureprint的GoogleMap的API密钥----
Total path for cmd prompt to get the MD5 fingureprint for the GoogleMap API Key----
如果您使用的是日食，然后 -
if you are using eclipse then--
D:\eclipse\jre\bin>keytool -list -keystore "C:\Users\XYZ\.android\debug.keystore"
MD5 fingurePrint看起来像这样 -
MD5 fingurePrint will look like this--
3E:F4:D6:E6:93:4D:BB:B8:62:3A:D6:0F:E0:FC:4C:65
当u得到的fingurePrint数afterthat获得API密钥使用此链接---
When u get the fingurePrint number afterthat to get the API Key use this link---
的http：// code.google.com /安卓/插件/谷歌的API /图-API signup.html
然后你也会得到你的系统的API密钥并能得到地图轻松instread电网....
Then u will get API key of your system and can get the Map easily instread of grids....
在您的MapView.xml使用此键---
Use this key in your MapView.xml---
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.google.android.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:enabled="true"
android:apiKey="046S_m5BQ43JIRtKiXQfldWwo2ddlU6dL6ca9SQ" />
</LinearLayout>
