Google Maps Android API V2覚書（地図処理系）

「Google Maps Android API V2を使ってみる」、「Google Maps Android API V2を使ってみる２」では、Google Mapsの表示のみをやってみました。
ここでは、地図関連のv2の機能を実装します。
メモみたいなものですが………。

イベント処理

情報表示・入力用のActivityを追加

カスタム・インフォウィンドウ

イベント処理

地図をタップ

地図上でタップした時、その位置を取得してToastで表示してみます。

MainActivity.java

import com.google.android.gms.maps.GoogleMap.OnMapClickListener;
import android.widget.Toast;

1 2	import com.google.android.gms.maps.GoogleMap.OnMapClickListener; import android.widget.Toast;

@Override
<span class="keyword">protected</span> <span class="keyword">void</span> onResume(){

    <span class="keyword">super</span>.onResume();

    <span class="keyword">int</span> resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

    <span class="keyword">if</span> (resultCode == ConnectionResult.SUCCESS){
        ・
        ・
        ・
        ・
        gMap.setOnMapClickListener(<span class="keyword">new</span> OnMapClickListener() {
            @Override
            <span class="keyword">public</span> <span class="keyword">void</span> onMapClick(LatLng point) {
                String posinfo = <span class="str">"clickpos\n"</span> + <span class="str">"latitude="</span> + point.latitude + <span class="str">", longitude="</span> + point.longitude;
                Toast.makeText(getApplicationContext(), posinfo, Toast.LENGTH_LONG).show();
            }
        });
    }
}

@Override

protected void onResume(){

super.onResume();

int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

if (resultCode == ConnectionResult.SUCCESS){

・

gMap.setOnMapClickListener(new OnMapClickListener() {

@Override

public void onMapClick(LatLng point) {

String posinfo = "clickpos\n" + "latitude=" + point.latitude + ", longitude=" + point.longitude;

Toast.makeText(getApplicationContext(), posinfo, Toast.LENGTH_LONG).show();

}

});

}

地図を長押し

            }
        });
    }

gMap.setOnMapLongClickListener(new OnMapLongClickListener() {

@Override

Toast.makeText(getApplicationContext(), "LongClick", Toast.LENGTH_LONG).show();

}

});

}

フリースクロールしてカメラが移動した時の位置を取得してToastで表示

位置はmoveendした時のものです。

MainActivity.java

 import com.google.android.gms.maps.GoogleMap.OnCameraChangeListener; 
 import android.widget.Toast;

1 2	import com.google.android.gms.maps.GoogleMap.OnCameraChangeListener; import android.widget.Toast;

    <span class="keyword">if</span> (resultCode == ConnectionResult.SUCCESS){
        ・
        ・
        ・
        ・
        gMap.setOnCameraChangeListener(<span class="keyword">new</span> OnCameraChangeListener() {
            @Override
            <span class="keyword">public</span> <span class="keyword">void</span> onCameraChange(CameraPosition position) {
                LatLng point = position.target;
                String posinfo = <span class="str">"latitude="</span> + point.latitude + <span class="str">", longitude="</span> + point.longitude;
                
                Toast.makeText(getApplicationContext(), posinfo, Toast.LENGTH_LONG).show();
            }
        });
    }
}

@Override

protected void onResume(){

super.onResume();

int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

if (resultCode == ConnectionResult.SUCCESS){

・

gMap.setOnCameraChangeListener(new OnCameraChangeListener() {

@Override

public void onCameraChange(CameraPosition position) {

LatLng point = position.target;

String posinfo = "latitude=" + point.latitude + ", longitude=" + point.longitude;

Toast.makeText(getApplicationContext(), posinfo, Toast.LENGTH_LONG).show();

}

});

}

情報表示・入力用のActivityを追加

メニュで開きます。

infoのフィールドに入れた情報はMainに戻った時、Toastで表示されます。

メニュのFile -> New で新しいClass（infoActivity.java）を追加。

AndroidManifest.xmlにactivityを追加。

resフォルダーにdrawableフォルダーを追加して、この中にボタン用画像(return.png)を追加。

以下の「com.example」（パッケージ名）は適当に読み替えてください。
