をスライドさせるとフラグメントのViewGroupにキャストすることはできません。この例外はビューはメニュー
slidingMenu.attachToActivity(this, SlidingMenu.LEFT);
ラインで発生しました。スライディングメニューにコンテンツを表示したい。 "this"オブジェクトは、AppCompatActivityクラスを継承するMapActivityクラス（私のカスタムJavaクラス）を参照しています。 この方法は、スライドメニューを初期化するための責任がある私のMapActivityクラスである：
private void initSlideMenu(){
slidingMenu = new SlidingMenu(this);
slidingMenu.setMode(SlidingMenu.RIGHT);
double dimension = Master.checkDimension(G.currentActivity);
Log.i("dimension", dimension + "");
if (dimension < 4)
slidingMenu.setBehindOffset(100);
else if (dimension >= 4 && dimension <= 5)
slidingMenu.setBehindOffset(300);
else if (dimension > 5)
slidingMenu.setBehindOffset(250);
slidingMenu.setFadeDegree(0.8f);
slidingMenu.setFadeEnabled(true);
slidingMenu.attachToActivity(this, SlidingMenu.LEFT);
if (dimension <= 6) {
slidingMenu.setSlidingEnabled(false);
}
View view = G.inflater.inflate(R.layout.map_details, null);
slidingMenu.setMenu(view);
}
と私のレイアウトファイル：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<fragment
android:name="com.google.android.gms.maps.MapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>
そして、私のJavaクラス：
public class MapActivity extends AppCompatActivity implements OnMapReadyCallback {
GoogleMap googleMap;
MapFragment mMapFragment;
LatLng myLocation;
public boolean firstTime = true;
ArrayList<Double> xList = new ArrayList<>();
ArrayList<Double> yList = new ArrayList<>();
SlidingMenu slidingMenu;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_activity);
MapFragment mapFragment = (MapFragment) getFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(final GoogleMap map) {
Log.i("Position", "SS");
map.setMyLocationEnabled(true);
final BitmapDescriptor saharsunLocationIcon = BitmapDescriptorFactory.fromResource(R.drawable.saharsun_smal);
final BitmapDescriptor myLocationIcon = BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED);
// Check if we were successful in obtaining the map.
map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
@Override
public boolean onMarkerClick(Marker marker) {
if (marker.getTitle().equals("I'm Hear")) {
MediaPlayer mPlayer2;
mPlayer2 = MediaPlayer.create(G.currentActivity, R.raw.cow_sound);
mPlayer2.start();
initSlideMenu();
Log.i("MARKER", marker.getTitle());
}
Log.i("MARKER", marker.getTitle());
return true;
}
});
if (map != null) {
map.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
@Override
public void onMyLocationChange(Location location) {
// TODO Auto-generated method stub
Random random = new Random();
myLocation = new LatLng(location.getLatitude(),
location.getLongitude());
Log.i("Position", location.getLatitude() + " " + location.getLongitude());
if (firstTime) {
map.animateCamera(CameraUpdateFactory.newLatLngZoom(myLocation, 16));
map.addMarker(new MarkerOptions().position(
new LatLng(location.getLatitude(), location.getLongitude())).title("It's Me!")).setIcon(myLocationIcon);
for (int i = 0; i < 5; i++) {
double x = random.nextDouble()/100 - 0.001 + location.getLatitude();
double y = random.nextDouble()/100 - 0.001 + location.getLongitude();
xList.add(x);
yList.add(y);
map.addMarker(new MarkerOptions().position(
new LatLng(x, y)).title("I'm Hear")).setIcon(saharsunLocationIcon);
}
firstTime = false;
}
}
});
}
}
@Override
protected void onResume() {
super.onResume();
G.currentActivity = this;
}
