在Android地图片段中显示自定义文字

地图

static

final

get

好吧,我现在一整天都在这,我放弃试图自己做到这一点!

我已经宣布了地图和位置

private GoogleMap googleMap;

宣布了这个位置

static final LatLng SECC = new LatLng(55.8607,-4.2871);

生成地图

googleMap=((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

建立了标记

Marker secc =googleMap.addMarker(new MarkerOptions().position(SECC)
            .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA))
            .title("SECC").snippet("Exhibition Way, Glasgow, G3 8YW\nSports: Boxing, Gymnastics, Judo, Netball, Wrestling, Weightlifting"));

将点击侦听器设置为地图

googleMap.setOnMarkerClickListener((OnMarkerClickListener)this);

设置自定义信息框

googleMap.setInfoWindowAdapter(new InfoWindowAdapter()
        {
         @Override
         public View getInfoWindow(Marker arg0)
            {
            return null;
             }

         public View getInfoContents(Marker marker)
            {
            View v = getLayoutInflater().inflate(R.layout.marker,null);

            TextView info=(TextView) v.findViewById(R.id.info);

            info.setText("hello");
            return v;
             }
        });

并设置click事件

googleMap.setOnMarkerClickListener(new OnMarkerClickListener()
        {
          @Override
           public boolean onMarkerClick(Marker marker)
            {
              marker.showInfoWindow();
              return true;
            }
    });

谁能指出我哪里出错？地图加载,您可以单击标记以获取代码段,但不显示自定义信息

以下代码可能对您有所帮助.

公共类Stacky扩展FragmentActivity实现OnMarkerClickListener {

静态最终LatLng SECC =新LatLng(55.8607,-4.2871); 私人GoogleMap mMap;

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


    mMap = ((SupportMapFragment)  getSupportFragmentManager().findFragmentById(R.id.map2)).getMap();
    mMap.setMyLocationEnabled(true);

     setUpMap();
       findSMSLocation();
    // Setting a custom info window adapter for the google map      
    mMap.setInfoWindowAdapter(new InfoWindowAdapter() {

        // Use default InfoWindow frame
        @Override
        public View getInfoWindow(Marker marker)   {                
            return null;
        }           

        // Defines the contents of the InfoWindow
        @Override
        public View getInfoContents(Marker marker) {

            // Getting view from the layout file info_window_layout
            View v = getLayoutInflater().inflate(R.layout.custom_info, null);

                TextView tvLat = (TextView)  v.findViewById(R.id.info);     
                tvLat.setText("info");
                tvLat.setTextColor(Color.GREEN);

            return v;
        }

    });


}

@Override
protected void onPause() {
    super.onPause();

}

@Override
protected void onResume() {
    super.onResume();
    setUpMapIfNeeded();
}


public void findSMSLocation() {
    // TODO Auto-generated method stub
    try{   

          mMap.addMarker(new MarkerOptions().position(SECC).title("SECC").snippet("Exhibition Way, Glasgow, G3 8YW\nSports: Boxing, Gymnastics, Judo, Netball, Wrestling, Weightlifting"));

          mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(SECC, 18.0f));

    }catch(Exception e){

        e.printStackTrace();
    }

}

private void setUpMapIfNeeded() {
    // Do a null check to confirm that we have not already instantiated the map.
    if (mMap == null) {
        // Try to obtain the map from the SupportMapFragment.
        mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map2))
                .getMap();
        mMap.setMyLocationEnabled(true);
        // Check if we were successful in obtaining the map.
        if (mMap != null) {
            setUpMap();
        }
    }
}



private void setUpMap() {
    mMap.getUiSettings().setCompassEnabled(true);
    mMap.getUiSettings().setTiltGesturesEnabled(true);
    mMap.getUiSettings().setRotateGesturesEnabled(true);
    mMap.getUiSettings().setScrollGesturesEnabled(true);
    mMap.getUiSettings().setZoomControlsEnabled(true);
    mMap.getUiSettings().setZoomGesturesEnabled(true);
}

@Override
public boolean onMarkerClick(Marker marker) {
    // TODO Auto-generated method stu
    return false;
}

}

您不需要将marker.showInfoWindow()添加到OnMarkerClickListner()接口.当您单击n到标记时,然后创建自定义窗口并使用您的自定义textview加载. 输出如下
