Question

我想在搜索视图中搜索位置，并使用标记在地图上显示该位置。单击标记后，我想显示一个带有位置名称等的信息窗口。我使用OSMDROID和OSMBONUSPACK。

问题： 标记显示为预期状态，并且其onClickListener确实触发，但是如果我从searchLocationOnMap调用onQueryTextSubmit，则不会显示信息窗口。该如何解决？

不起作用（如果单击标记，则不会显示任何信息窗口）：

 searchViewMap?.setOnQueryTextListener(object : androidx.appcompat.widget.SearchView.OnQueryTextListener {
        override fun onQueryTextSubmit(query: String?): Boolean {
            val location = searchViewMap?.query.toString()
            if (location != null && location != "") {
                try {
                    searchLocationOnMap("Moosach Bhf")
                } catch (e: java.lang.Exception) {
                    Timber.d("Error while searching for location on map")
                }
            }
            return true
        }

        override fun onQueryTextChange(newText: String?): Boolean {
            return true
        }

    })

由于某些原因，显示了我是从searchLocationOnMap还是常规onViewCreated呼叫button.setOnClickListener{}。

有效（如果单击标记，则显示信息窗口）：

btn.setOnClickListener { searchLocationOnMap("Moosach Bhf") }

这是searchLocationOnMap（）：

private fun searchLocationOnMap(keyword: String) = GlobalScope.launch(Dispatchers.Main) {
    removeOldLocationsFromMap()

    val locationAddress = withContext(Dispatchers.Default) { obtainAddressFromKeyword(keyword) }

    if (locationAddress == null) {
        Toast.makeText(context, "No address found for keyword $keyword", Toast.LENGTH_SHORT).show()
    } else {
            val marker = createMarkerFromAddress(locationAddress)

            mPOIOverlayFolder.add(marker)
            map.controller.animateTo(marker.position)
            map.invalidate()

    }

这是getAdressFromKeyword：

 private fun obtainAddressFromKeyword(keyword: String): Address? {
    val result = GeocoderNominatim("TestUserAgent").getFromLocationName(keyword, 1).firstOrNull()
    Timber.d("result: $result")
    return result
}

这是createMarkerFromAddress：

private fun createMarkerFromAddress(address: Address): Marker {
    val poiMarker = Marker(map)
    poiMarker.title = address.getAddressLine(0)
    poiMarker.snippet = "Lat : ${address.latitude},\n Long ${address.longitude}"
    poiMarker.position = GeoPoint(address.latitude, address.longitude)
    poiMarker.icon = ContextCompat.getDrawable(applicationContext, R.drawable.poi_black)
    poiMarker.infoWindow = MarkerInfoWindow(R.layout.marker_info_bubble, map)
    poiMarker.setOnMarkerClickListener { marker, map -> onMarkerClick(marker) }


    return poiMarker
}

这是onMarkerClick：

private fun onMarkerClick(marker: Marker) : Boolean {
    marker.showInfoWindow()
    marker.infoWindow.view.bringToFront()
    Timber.d("Clicked Marker ${marker.title}, infowindowshown: ${marker.isInfoWindowShown}")

    return true

木材结果（在两种情况下）：

单击标记的Memminger Platz，信息窗口显示：是

我用类似的方法解决它

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextSubmit(String query) {
        Log.i("MyApp", searchView.getQuery().toString());
        consultarListaParadas(searchView.getQuery().toString());
        getActivity().runOnUiThread(new Runnable() {
            public void run() {
                adaptadorListaParadasBus.setListaParadas(listaParadas);
                adaptadorListaParadasBus.notifyDataSetChanged();
            }
        });

        return true;
    }

    @Override
    public boolean onQueryTextChange(String newText) {

        if(newText.equals("")){
            this.onQueryTextSubmit("");
        }
        return true;
    }
});

必须禁用map.parent视图。

从SearchView onQueryTextSubmit创建时不显示视图
