滚动视图内的地图不可滚动

Question

我在垂直滚动视图中有一个地图片段。我希望它可以滚动。但它不工作。我尝试从这些答案中添加透明图像和自定义 Scrollview：

Google Maps API v2 SupportMapFragment inside ScrollView - users cannot scroll the map vertically

我的布局结构：

<?xml version="1.0" encoding="utf-8"?>

请提出一些解决方案。我正在尝试 Marshmallow 上的所有内容。

Answer 1

您可以在滚动视图中滚动 google 地图。见下文 link 我在 android 中描述了如何在 scrollview 中滚动地图： http://newtech4you4ever.blogspot.in/2016/08/scroll-googlemap-in-scrollview-android.html

Answer 2

您可以尝试下面的代码，看看它是否适合您。

View customView = null;
ScrollView scrollViewParent = null;

scrollViewParent = (ScrollView) v.findViewById(R.id.scrollViewParent);
customView = (View) v.findViewById(R.id.customView);

customView.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        int action = event.getAction();
        switch (action) {
        case MotionEvent.ACTION_DOWN:
            // Disallow ScrollView to intercept touch events.
            scrollViewParent.requestDisallowInterceptTouchEvent(true);
            // Disable touch on transparent view
            return false;

        case MotionEvent.ACTION_UP:
            // Allow ScrollView to intercept touch events.
            scrollViewParent.requestDisallowInterceptTouchEvent(false);
            return true;

        case MotionEvent.ACTION_MOVE:
            scrollViewParent.requestDisallowInterceptTouchEvent(true);
            return false;

        default:
            return true;
        }
    }
});

现在在 XML 文件中

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/scrollViewParent"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
        <fragment
            android:id="@+id/map"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            class="com.google.android.gms.maps.SupportMapFragment" />

        <View
            android:id="@+id/customView"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:background="@android:color/transparent" />
</ScrollView>

Answer 3

public class MySupportMapFragment extends SupportMapFragment {

    private OnTouchListener mListener;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {

        View layout = super.onCreateView(inflater, parent, savedInstanceState);
        TouchableWrapper frameLayout = new TouchableWrapper(getActivity());
        frameLayout.setBackgroundColor(getResources().getColor(android.R.color.transparent));
        ((ViewGroup) layout).addView(frameLayout,
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

        return layout;
    }

    public void setListener(OnTouchListener listener) {
        mListener = listener;
    }

    public interface OnTouchListener {
        public abstract void onTouch();
    }

    public class TouchableWrapper extends FrameLayout {

        public TouchableWrapper(Context context) {
            super(context);
        }

        @Override
        public boolean dispatchTouchEvent(MotionEvent event) {
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    mListener.onTouch();
                    break;
                case MotionEvent.ACTION_UP:
                    mListener.onTouch();
                    break;
            }
            return super.dispatchTouchEvent(event);
        }
    }
}

在你的activity/fragment中，在onCreate/onViewCreated

中添加以下代码

ScrollView nScrollView = (ScrollView) findViewById(R.id.scrollViewParent);
            MySupportMapFragment mSupportMapFragment;
            mSupportMapFragment = (MySupportMapFragment) getChildFragmentManager().findFragmentById(R.id.googleMap);

            mSupportMapFragment.setListener(new MySupportMapFragment.OnTouchListener() {
                        @Override
                        public void onTouch() {
                            mScrollView.requestDisallowInterceptTouchEvent(true);
                        }
                    });

            if (mSupportMapFragment != null) {
                mSupportMapFragment.getMapAsync(new OnMapReadyCallback() {
                    @Override
                    public void onMapReady(GoogleMap googleMap) {
                        if (googleMap != null) {
                            googleMap.getUiSettings().setAllGesturesEnabled(true);
                            googleMap.getUiSettings().setZoomControlsEnabled(true);
                            LatLng marker_latlng = new LatLng(lat, lon);
                            CameraPosition cameraPosition = new CameraPosition.Builder().target(marker_latlng).zoom(15.0f).build();
                            CameraUpdate cameraUpdate = CameraUpdateFactory.newCameraPosition(cameraPosition);
                            googleMap.moveCamera(cameraUpdate);
                            if (latitude != null && longitude != null) {
                                    googleMap.addMarker(new MarkerOptions().position(marker_latlng).title("Address"));
}
                        }
                    }
                });
            }

& 你的布局是这样的

<fragment
        android:id="@+id/googleMap"
        class="com.yourpackagename.MySupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
