특정 마커의 경우에만 InfoWindowAdapter를 설정하는 방법

Question

맵보기에서 특정 마커의 'setInfoWindowAdapter'프라퍼티를 사용하려하지만 '마커 2'와 함께 어떤 이유로 든 제목 아래에 원치 않는 공백이 나타나는 것 같습니다 (마커 2) (첨부 스크린 샷 참조). 이런 일이 발생하지 않도록하기 위해 할 수있는 일은 무엇입니까?

FragmentCustomMapview.java

public class FragmentCustomMapview extends android.support.v4.app.Fragment implements OnMapReadyCallback {

Answer 1

추가하지 마십시오에 TextView snippet 당신의 LinearLayout info 당신의 Marker에는 미리보기가없는 경우 :

@Override 
public View getInfoContents(Marker marker) { 

    Context mContext = getActivity(); 

    LinearLayout info = new LinearLayout(mContext); 
    info.setOrientation(LinearLayout.VERTICAL); 

    TextView title = new TextView(mContext); 
    title.setTextColor(Color.BLACK); 
    title.setGravity(Gravity.CENTER); 
    title.setTypeface(null, Typeface.BOLD); 
    title.setText(marker.getTitle()); 
    title.setSingleLine(false); 

    info.addView(title); 

    if (marker.getSnippet() != null) { 
     TextView snippet = new TextView(mContext); 
     snippet.setTextColor(Color.GRAY); 
     snippet.setText(marker.getSnippet()); 
     snippet.setSingleLine(false); 

     info.addView(snippet); 
    } 

    return info; 
}
