How to Set Google Map Fragment Inside Scroll View

how to set google map fragment inside scroll view

Create a custom SupportMapFragment so that we can override its touch event:

WorkaroundMapFragment.java

import android.content.Context;
import android.os.Bundle;
import android.widget.FrameLayout;

import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewGroup;

import com.google.android.gms.maps.SupportMapFragment;

public class WorkaroundMapFragment extends SupportMapFragment {
    private OnTouchListener mListener;

    @Override
    public View onCreateView(LayoutInflater layoutInflater, ViewGroup viewGroup, Bundle savedInstance) {
        View layout = super.onCreateView(layoutInflater, viewGroup, savedInstance);

        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);
        }
    }
}

In this above class, we intercept the touch event by using TouchableWrapper.class that extends the FrameLayout. There is also a custom listener OnTouchListener to dispatch the touch event to the main activity named MyMapActivity that handles the map. When the touch event occurred, dispatchTouchEvent will be called and the listener mListener will handle it.

Then replace fragment class in xml with this class="packagename.WorkaroundMapFragment" instead of com.google.android.gms.maps.SupportMapFragment

Then in your activity initialize map as follows:

private GoogleMap mMap;

inside onCreate do this:

  // check if we have got the googleMap already
  if (mMap == null) {
        SupportMapFragment mapFragment = (WorkaroundMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
        mapFragment.getMapAsync(new OnMapReadyCallback() {
            Override
                public void onMapReady(GoogleMap googleMap)
                    {
                        mMap = googleMap;
                        mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
                        mMap.getUiSettings().setZoomControlsEnabled(true);
    
                        mScrollView = findViewById(R.id.scrollMap); //parent scrollview in xml, give your scrollview id value
                        ((WorkaroundMapFragment) getChildFragmentManager().findFragmentById(R.id.map))
                                .setListener(new WorkaroundMapFragment.OnTouchListener() {
                            @Override
                            public void onTouch()
                                {
                                        mScrollView.requestDisallowInterceptTouchEvent(true);
                                }
                            });
                    }
        });
    }

Android SupportMapFragment for moving Google Map within Scrollview

Face same issue in my app, I resolve this using interception scroll view touch using custom Scrollview

CustomScrollView:

public class CustomScrollView extends ScrollView {

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

public CustomScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public CustomScrollView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    final int action = ev.getAction();
    switch (action) {
        case MotionEvent.ACTION_DOWN:
            //Log.i("CustomScrollView", "onInterceptTouchEvent: DOWN super false" );
            super.onTouchEvent(ev);
            break;

        case MotionEvent.ACTION_MOVE:
            return false; // redirect MotionEvents to ourself

        case MotionEvent.ACTION_CANCEL:
            // Log.i("CustomScrollView", "onInterceptTouchEvent: CANCEL super false" );
            super.onTouchEvent(ev);
            break;

        case MotionEvent.ACTION_UP:
            //Log.i("CustomScrollView", "onInterceptTouchEvent: UP super false" );
            return false;

        default:
            //Log.i("CustomScrollView", "onInterceptTouchEvent: " + action );
            break;
    }

    return false;
}

@Override
public boolean onTouchEvent(MotionEvent ev) {
    super.onTouchEvent(ev);
    //Log.i("CustomScrollView", "onTouchEvent. action: " + ev.getAction() );
    return true;
  }
}

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

Apply a transparent image over the mapview fragment.

<RelativeLayout
    android:id="@+id/map_layout"
    android:layout_width="match_parent"
    android:layout_height="300dp">

    <fragment
        android:id="@+id/mapview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="-100dp"
        android:layout_marginBottom="-100dp"
        android:name="com.google.android.gms.maps.MapFragment"/>

    <ImageView
        android:id="@+id/transparent_image"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@color/transparent" />

</RelativeLayout>   

Then set requestDisallowInterceptTouchEvent(true) for the main ScrollView. When the user touches the transparent image and moves disable the touch on the transparent image for MotionEvent.ACTION_DOWN and MotionEvent.ACTION_MOVE so that map fragment can take Touch Events.

ScrollView mainScrollView = (ScrollView) findViewById(R.id.main_scrollview);
ImageView transparentImageView = (ImageView) findViewById(R.id.transparent_image);

transparentImageView.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.
                mainScrollView.requestDisallowInterceptTouchEvent(true);
                // Disable touch on transparent view
                return false;

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

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

           default: 
                return true;
        }   
    }
});

This worked for me. Hope it helps you..

MapFragment in ScrollView

Applying a transparent image over the mapview fragment seems to resolve the issue. It's not the prettiest, but it seems to work. Here's an XML snippet that shows this:

<RelativeLayout
        android:id="@+id/relativeLayout1"
        android:layout_width="match_parent"
        android:layout_height="300dp" >

        <fragment
            android:id="@+id/map"
            android:name="com.google.android.gms.maps.MapFragment"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"/>

        <ImageView
            android:id="@+id/imageView123"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/temp_transparent" />         
</RelativeLayout>

Map inside scrollview not scrollable

you can scroll google map inside scrollview.
