android - 地図を追加しようとしてエラーが発生しました: android.view.InflateException: Binary XML file line #9: Error inflating class com.google.android.maps.MapView

Question

MapActivity を拡張する次のクラスを作成します。エラーはこのクラスの行にあります

View view = infalInflater.inflate(R.layout.car_map_view, null);

public class ShowCarMapChild extends MapActivity {
private MapView mapView;
private Car car;
private String tag;



@Override
protected void onCreate(Bundle icicle) {
    // TODO Auto-generated method stub
    super.onCreate(icicle);
    setContentView(R.layout.car_map_view);
}

public void setCar(Car car){
    this.car = car;
}

public void setTag (String tag){
    this.tag = tag;
}

public String getTag (){
    return tag;
}

public View getMapView(Context context){
    LayoutInflater infalInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
    View view = infalInflater.inflate(R.layout.car_map_view, null);
    setMap(view,context);
    return view;
}

public void setMap(View view, Context context){
    mapView = (MapView) view.findViewById(R.id.mapShowCarLocation);
    MapController mc = mapView.getController();
    mc.animateTo(car.getLocation());
    mc.setZoom(15);
    PinpointItem point = new PinpointItem(car.getLocation(), car, context);
    Drawable d = getResources().getDrawable(R.drawable.pinpoint);
    CustomPinpointOverlay overlay = new CustomPinpointOverlay(d);
    overlay.insertPinpoint(point);
    mapView.getOverlays().add(overlay);
}
@Override
protected boolean isRouteDisplayed() {
    // TODO Auto-generated method stub
    return false;
}

}

これはxmlファイルです：

 <?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="150dip"
android:orientation="vertical" >

    <com.google.android.maps.MapView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/mapShowCarLocation"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
        android:apiKey="0UFOPeLgKxoW8VGjdzV5QN6N53N7733i1kTFI3g"
        android:enabled="true" />
</LinearLayout>

それが役立つことを願っています

Answer 1

マップビューをアダプタ内に配置することはできません（少なくとも別のクラスには配置できません）。Mapviewはビューではありません。mapviewは、結合されて分割できない一種のアクティビティ/ビューです。あなたが何を達成しようとしているのかはわかりませんが、説明していただければ、別のアプローチを提案できるかもしれません。

Answer 2

公式の Java ドキュメントによると、マップ MapActivity ごとに使用できるマップ ビューは 1 つだけです。次のリンクでも同じ問題について説明しています。

1 つのアクティビティで 2 つの MapView を作成するには?

したがって、問題を解決するために考えられる解決策の 1 つは、Google 静的マップ API を使用し、ユーザーがサティック マップ ビューをクリックしたときに完全な mapView を開くことです。静的マップを追加する方法については、次の質問で @Siddharth Lele からの回答を確認してください...

Android - Listview 内に含まれる MapView

http URIを画像URIとして設定できるスマート画像ビューのようなものを使用できます。静的マップ URI を画像 URI として設定して、マップを ImageView に表示できます。スマート イメージ ビューのソース コードは、次の場所でも入手できます。

https://github.com/loopj/android-smart-image-view

または、アプリを少し再設計して、別のマップ ビューを作成し、複数のオーバーレイを作成してデータを表示することもできます。
