問題描述

我正在開發一個 Android 應用程序并使用 GoogleMaps API v2.此應用程序到目前為止工作，但我想在地圖中搜索路徑:

I'm developing an Android application and using GoogleMaps API v2. This application works so far but I want search in the map with a path:

截圖:

我的代碼:

Position_mark = new LatLng(35.7008, 51.437);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(Position_mark, 15));
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
map.setOnMapClickListener(this);
map.setOnMapLongClickListener(this);
map.setOnMarkerDragListener(this);

...

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    //Used to put dark icons on light action bar

    mGoItem = menu.add(0, Delete_ITEM_ID, 0, null);
    mGoItem.setIcon(R.drawable.ic_launcher)
           .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

    SearchView searchView = 
        new SearchView(getSupportActionBar().getThemedContext());
    searchView.setQueryHint("Search for Places…");
    searchView.setIconified(false);

    menu.add("Search")
        .setIcon(R.drawable.abs__ic_search)
        .setActionView(searchView)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

        @Override
        public boolean onQueryTextSubmit(String newText) {
            return true;
        }

        /**
         * Called when the query text is changed by the user.
         * @param newText the new content of the query text field.
         * @return false if the SearchView should perform the 
         * default action of showing any suggestions if available, 
         * true if the action was handled by the listener.
         */
        @Override
        public boolean onQueryTextChange(String newText) {
            Toast.makeText(getApplicationContext(), newText, 1).show();
            return true;
        }
    });

    return true;
}

@Override
public void onMapClick(LatLng point) {
    // TODO Auto-generated method stub
    // tvLocInfo.setText(point.toString());
    map.animateCamera(CameraUpdateFactory.newLatLng(point));
    map.clear();

    Marker Kiel = map.addMarker(new MarkerOptions()
        .position(point)
        .title("Kiel")
        .snippet("Kiel is cool").draggable(true)
        .icon(BitmapDescriptorFactory
        .fromResource(R.drawable.ic_launcher)));
}

我使用 ActionBarSherlock 和 SearchView 進行搜索.如何在 GoogleMaps API 中搜索路徑不是緯度或經度?

I use ActionBarSherlock and SearchView for searching. How to search in GoogleMaps API with path not latitute or longitude?

推薦答案

您可以使用地理編碼來搜索或查看這個使用 json 解析 GoogleMaps 的精彩教程.

You can use geocoding to search or see this nice tutorial which uses json parsing GoogleMaps.

• 添加Google Places Autocomplete API 作為 Android 搜索對話框中的自定義建議
