[안드로이드] ScrollView 안에 지도 달기 (Activity)

MapView inside ScrollView (activity)

리스트뷰안에 맵을 넣는 것을 검색하다가 적용 및 테스트를 해봤습니다.

위의 주소에 있는 코드에서는 ScrollView와 MapView 의 터치 이벤트를 동시에 적용되는 기능도 처리가 되어 있어서

여러모로 쓸모가 많은 코드네요.

fragment_maps.xml 맵뷰의 레이아웃을 정의 합니다.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <com.google.android.gms.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

WorkaroundMapFragment.java의 클레스를 정의합니다.

import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewGroup;
import android.widget.FrameLayout;

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) {
            if(mListener == null)
                return false;
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    mListener.onTouch();
                    break;
                case MotionEvent.ACTION_UP:
                    mListener.onTouch();
                    break;
            }
            return super.dispatchTouchEvent(event);
        }
    }
}

코드 적용

Activity layout 에서 ScrollView 안에 정의합니다.

<ScrollView

...

<fragment android:tag="fragment_map"
    android:id="@+id/fragment_map"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:layout_marginTop="20dp"
    class="your package .WorkaroundMapFragment"/>
...

</ScrollView>

Activity 내에서의 처리

public class MainActivity extends AppCompatActivity {

    private GoogleMap mMap;
    private ScrollView mScrollView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_back);

        WorkaroundMapFragment mapFrag = (WorkaroundMapFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_map);
        mapFrag.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(GoogleMap googleMap) {
                if (ActivityCompat.checkSelfPermission(getBaseContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getBaseContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                    boolean permission = hasAllPermissionsGranted();
                    if (permission) {
                        Log.e("test","permission "+permission);
                    }
                    return;
                }
                googleMap.setMyLocationEnabled(true);
                googleMap.getUiSettings().setZoomControlsEnabled(true);
            }
        });

        mScrollView = (ScrollView) findViewById(R.id.sv_container);
        mapFrag.setListener(new WorkaroundMapFragment.OnTouchListener() {
            @Override
            public void onTouch() {
                mScrollView.requestDisallowInterceptTouchEvent(true);
            }
        });
    }

    //권한 추가
    private static final int REQUEST_PERMISSIONS = 1;
    private static final String[] MY_PERMISSIONS = {
            Manifest.permission.ACCESS_COARSE_LOCATION,
            Manifest.permission.ACCESS_FINE_LOCATION
    };
    private final static int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
    private boolean hasAllPermissionsGranted() {
        for (String permission : MY_PERMISSIONS) {
            if (ContextCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(this, MY_PERMISSIONS, REQUEST_PERMISSIONS);
                return false;
            }
        }
        return true;
    }
}
