私のアプリケーションでは、edittext に入力した住所に基づいて場所をマップにピン留めしたり、onMapReady 関数に表示されるピンを移動したりできるアクティビティがあります。
私のアクティビティのレイアウトには、地図を表示するフラグメント、前のアクティビティのピンの位置に関する情報を返すボタン、住所を入力してボタンを押すと、地図上にあった前のピンが削除され、入力した場所で新しいものが表示されます (存在する場合)。
-- これはonMapReady
、検索ボタンにリスナーがあり、ピンを初期化する関数と、ドラッグ後にピンの位置を取得する関数です。

上記のコードを修正した後の更新: クラスから前のアクティビティに位置を返すコード (未解決 - 常に NULL 値を取得):
クラスで:
@Override
protected void onPostExecute(LatLng result) {
Log.i("GEOCODE", result.toString());
Intent i = new Intent(this.mainContxt , MapsActivity.class );
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra( "latlng" , result );
this.mainContxt.startActivity(i);
super.onPostExecute(result);
}
MapsActivity の onCreate には、次のようなものがあります。
if (getIntent() != null) {
Intent intent = getIntent();null){
position_from_address = intent.getStringExtra("latlng");
}
その後、アクティビティの検索ボタンの onClickListener で、次のような位置を取得しています。
if (position_from_address != null){
String[] latlong = position_from_address.split(",");
double latitude = Double.parseDouble(latlong[0]);
double longitude = Double.parseDouble(latlong[1]);
position = new LatLng(latitude, longitude);
