I want the address I entered on the Naver map to be marked with a marker.

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Address"
                android:id="@+id/etmapname"/>

            <EditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Detailed address"
                android:id="@+id/etadress"/>

            <Button
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Check Location"/>

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="300dp"
                android:id="@+id/mapmap"
                android:orientation="vertical"/>

    mMapView = new NMapView(this);
    mMapView.setBuiltInZoomControls(true, null);
    mMapView.setClickable(true);
    mMapView.setApiKey(API_KEY);

    mLinearLayout = (LinearLayout)findViewById(R.id.mapmap);
    mLinearLayout.addView(mMapView);
