は、どのように私は私は本当にそれにいくつかの助けを必要としています疑問を持っているユーザーの場所を取得し、彼にマップ

Question

を表示することができます 私はアプリケーションを開発し、私が欲しい：

は

ユーザーの場所を1-取得し、公開します地図。 2 - ユーザーは地図の任意の場所にピンを置くことができます。このピンに調整して変数に格納します。

注：2.1のアプリケーションはgoogle APIを使用する必要がありますか？はいの場合、google APIはマップではなくアクティビティをサポートしていますか？

私はグーグルで検索すると、このコードを見つける：ユーザーを取得しません それは、1：

package com.java.locate; 

import android.app.Activity; 
import android.content.Context; 
import android.location.Location; 
import android.location.LocationListener; 
import android.location.LocationManager; 
import android.os.Bundle;

import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.Toast; 



    public class AndroidLbsGeocodingProjectActivity extends Activity { 
    /** Called when the activity is first created. */ 
    private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters 
    private static final long MINIMUM_TIME_BETWEEN_UPDATES = 1000; // in Milliseconds 
    protected LocationManager locationManager; 
    protected Button retrieveLocationButton; 



@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    retrieveLocationButton = (Button) findViewById(R.id.retrieve_location_button); 

      locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 

      locationManager.requestLocationUpdates(
         LocationManager.GPS_PROVIDER, 
        MINIMUM_TIME_BETWEEN_UPDATES, 
         MINIMUM_DISTANCE_CHANGE_FOR_UPDATES, 
        new MyLocationListener() 
       ); 

      retrieveLocationButton.setOnClickListener(new OnClickListener() { 

        public void onClick(View v) { 
         showCurrentLocation(); 
        } 
      });  

      } 

      protected void showCurrentLocation() { 

       Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); 

       if (location != null) { 
        String message = String.format(
          "Current Location \n Longitude: %1$s \n Latitude: %2$s", 
          location.getLongitude(), location.getLatitude() 
        ); 
        Toast.makeText(AndroidLbsGeocodingProjectActivity.this, message, 
          Toast.LENGTH_LONG).show(); 
       } 

      } 

      private class MyLocationListener implements LocationListener { 

       public void onLocationChanged(Location location) { 
        String message = String.format(
         "New Location \n Longitude: %1$s \n Latitude: %2$s", 
          location.getLongitude(), location.getLatitude() 
        ); 
        Toast.makeText(AndroidLbsGeocodingProjectActivity.this, message, Toast.LENGTH_LONG).show(); 
       } 

       public void onStatusChanged(String s, int i, Bundle b) { 
        Toast.makeText(AndroidLbsGeocodingProjectActivity.this, "Provider status changed", 
          Toast.LENGTH_LONG).show(); 
       } 

      public void onProviderDisabled(String s) { 
        Toast.makeText(AndroidLbsGeocodingProjectActivity.this, 
          "Provider disabled by the user. GPS turned off", 
          Toast.LENGTH_LONG).show(); 
       } 

       public void onProviderEnabled(String s) { 
        Toast.makeText(AndroidLbsGeocodingProjectActivity.this, 
          "Provider enabled by the user. GPS turned on", 
          Toast.LENGTH_LONG).show(); 
       } 

     } 




} 

は、これは、GoogleのAPIを使用して、別のコード、このですが、私はこのコードを使用して2つの問題を持っています場所、それは私にマップを表示するだけです。 2つのgoogle APIはマップだけでなく、別のアクティビティで動作しますか？

Googleマップを使用できます。 Map Apiキーが必要です。 Eclipseを使用している場合は、 http://mobiforge.com/developing/story/using-google-maps-android
