Question

我的谷歌地图应用程序问题出现了问题这是我的清单代码..

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.GPS"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-sdk android:minSdkVersion="8" />
    <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">

        <activity android:name=".GPS_Testing"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <uses-library android:name="com.google.android.maps"></uses-library>
    </application>


</manifest>

这是我的main.xml文件

<?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" >


    <com.google.android.maps.MapView
    android:id="@+id/mapview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:apiKey="0trTDjnICco0ZzgjmvY3zTe7PNXzAsoG9iRWtPw"
    />

</LinearLayout>

这是我的主要计划

package com.GPS;

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

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.Toast;

public class GPS_Testing extends MapActivity {
    private MapView mapView;
    private MapController mapController;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);    
    /*Create MapView Target*/
    mapView=(MapView)findViewById(R.id.mapview);

    LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    LocationListener mlocListener = new MyLocationListener();
    mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
    mapView.setBuiltInZoomControls(true);

    mapController = mapView.getController();
    mapController.setZoom(16); 
    }

    /* Class My Location Listener */

    public class MyLocationListener implements LocationListener

    {

    @Override

    public void onLocationChanged(Location loc)

    {

    loc.getLatitude();

    loc.getLongitude();

    String Text = "My current location is:" +

    "Latitud =" + loc.getLatitude() +

    "Longitud =" + loc.getLongitude();

    Toast.makeText( getApplicationContext(),

    Text,

    Toast.LENGTH_LONG).show();

    }

    @Override

    public void onProviderDisabled(String provider)

    {

    Toast.makeText( getApplicationContext(),

    "Gps Disabled",

    Toast.LENGTH_SHORT ).show();

    }

    @Override

    public void onProviderEnabled(String provider)

    {

    Toast.makeText( getApplicationContext(),

    "Gps Enabled",

    Toast.LENGTH_SHORT).show();

    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
        // TODO Auto-generated method stub

    }

    }
    @Override
    protected boolean isRouteDisplayed()
    {
        return false;
    }
}
