Android 中带有释放键的地图显示
我已经为我的应用程序创建了发布密钥。但它没有显示地图。我做错了什么?我通过右键单击项目创建发布密钥 - >导出 - >给出别名 - >...喜欢然后通过使用 Keytool,我得到了发布密钥。我在我的 xml 上使用了它。
我的代码:
public class SampleMapActivity extends MapActivity {
MapView myMapView = null;
MapController myMC = null;
GeoPoint geoPoint = null;
double latitude = 12.937875, longitude = 77.622313;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myMapView = (MapView) findViewById(R.id.myGMap);
geoPoint = new GeoPoint((int) (latitude * 1000020), (int) (longitude * 1000020));
myMapView.setStreetView(true);
myMC = myMapView.getController();
myMC.setCenter(geoPoint);
myMC.setZoom(15);
myMapView.setBuiltInZoomControls(true);
myMapView.displayZoomControls(true);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_I) {
myMapView.getController().setZoom(myMapView.getZoomLevel() + 1);
return true;
} else if (keyCode == KeyEvent.KEYCODE_O) {
myMapView.getController().setZoom(myMapView.getZoomLevel() - 1);
return true;
} else if (keyCode == KeyEvent.KEYCODE_S) {
myMapView.setSatellite(true);
return true;
} else if (keyCode == KeyEvent.KEYCODE_M) {
myMapView.setSatellite(false);
return true;
}
return false;
}
}
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"
android:layout_height="fill_parent"

My code:
public class SampleMapActivity extends MapActivity {
MapView myMapView = null;
MapController myMC = null;
GeoPoint geoPoint = null;
double latitude = 12.937875, longitude = 77.622313;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myMapView = (MapView) findViewById(R.id.myGMap);
geoPoint = new GeoPoint((int) (latitude * 1000020), (int) (longitude * 1000020));
myMapView.setStreetView(true);
myMC = myMapView.getController();
myMC.setCenter(geoPoint);
myMC.setZoom(15);
myMapView.setBuiltInZoomControls(true);
myMapView.displayZoomControls(true);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_I) {
myMapView.getController().setZoom(myMapView.getZoomLevel() + 1);
return true;
} else if (keyCode == KeyEvent.KEYCODE_O) {
myMapView.getController().setZoom(myMapView.getZoomLevel() - 1);
return true;
} else if (keyCode == KeyEvent.KEYCODE_S) {

让我们获取 MapAPIKey。
1)如何创建KeyStore
现在您的keystore和Apk已创建。
2)如何获取证书指纹 (MD5)
了解更多详情去这里
现在你得到了指纹,如
证书指纹(MD5): 94:1E:43:49:87:73:BB:E6:A6:88:D7:20:F1:8E:B5:98
3)如何获取MapApiKey
点击此处并粘贴您的 MD5,然后您将获得 MapAPIKey。
在您的应用程序中使用此密钥。
4)测试
使用此密钥库创建新的 apk 并检查..
lets go for get MapAPIKey.
1)How to create KeyStore
Now your keystore and Apk is created.
2)How to get Certificate fingerprint (MD5)
for more detail go here
Now you got fingerprint like as
Certificate fingerprint (MD5): 94:1E:43:49:87:73:BB:E6:A6:88:D7:20:F1:8E:B5:98
3)How to get MapApiKey
click here and paste your MD5 then u will get MapAPIKey.
Use this key in your application.
4)Test
create new apk using this keystore and check..
