android SetOnInfo WindowClickListener-传递更多值

我在我的android应用程序中使用谷歌地图，上面有很多标记。单击标记后，将显示标题。但我需要在点击该标题后打开一个具有更多值的新活动-它将显示在文本视图中

我当前的解决方案现在可以工作了，但每次都会打开相同的信息-如果单击任何标记，就会传递上一项的值。我需要每个标记传递它的值

    void createMarkersFromJson(String json) throws JSONException {

    JSONObject jsonObj = new JSONObject(json);
    JSONArray actors = jsonObj.getJSONArray("result");

    for (int i = 0; i < actors.length(); i++) {
        final JSONObject c = actors.getJSONObject(i);

        final double g1 = Double.parseDouble(c.getString("gps1"));
        final double g2 = Double.parseDouble(c.getString("gps2"));
        LatLng poss = new LatLng(g1,g2);

        final String title = c.getString("name");
        final String place = c.getString("place");
        final String place2 = c.getString("place2");
        final String perexfull = c.getString("perexfull");
        final String img1 = c.getString("img1");
        final String info = c.getString("info");

   mMap.addMarker(new MarkerOptions().position(poss).title(title).icon(BitmapDescriptorFactory.fromResource(R.drawable.icon)));

        mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {

            @Override
            public void onInfoWindowClick(Marker marker) {
                Intent intent = new Intent(MapsActivity.this, SingleitemView.class);

                intent.putExtra("place", place);
                intent.putExtra("place2", place2);
                intent.putExtra("perexfull", perexfull);
                intent.putExtra("name", title);
                intent.putExtra("img1", img1);
                intent.putExtra("info", info);
                startActivity(intent);
            }
        });

    }
      }

void createMarkersFromJson（字符串json）抛出JSONException{
JSONObject jsonObj=新的JSONObject（json）；
JSONArray actors=jsonObj.getJSONArray（“结果”）；

我还尝试将SetOnInfo WindowClickListener从for循环中移出，但随后的变量（如place、info）未知。

不确定是否完全正确，但此解决方案最终对我有效！我将SetOnInfo WindowClickListener从循环中取出，然后：

    HashMap<Marker, String> values1 = new HashMap<Marker, String>();
    HashMap<Marker, String> values2 = new HashMap<Marker, String>();

 values1.put(marker, c.getString("place"));
 values1.put(marker, c.getString("place2"));

首先，定义一个MarkerInfo类，该类将保存每个标记的所有信息：

public class MarkerInfo {
    public String mTitle;
    public String mPlace;
    public String mPlace2;
    public String mPerexfull;
    public String mImg1;
    public String mInfo;

    public MarkerInfo(String title, String place, String place2, String perexfull, String img1, String info) {
        mTitle = title;
        mPlace = place;
        mPlace2 = place2;
        mPerexfull = perexfull;
        mImg1 = img1;
        mInfo = info;
    }
}

然后，将HashMap定义为成员变量，Marker作为键，MarkerInfo对象作为值：

GoogleMap mMap;
Map<Marker, MarkerInfo> mMarkerMap = new HashMap<>();

GoogleMap-mMap；
Map mMarkerMap=newhashmap（）；

然后，为每个标记创建一个MarkerInfo对象，并将其添加到HashMap中。然后，单击信息窗口时，从相应的MarkerInfo对象检索信息：

void createMarkersFromJson(String json) throws JSONException {

    JSONObject jsonObj = new JSONObject(json);
    JSONArray actors = jsonObj.getJSONArray("result");

    for (int i = 0; i < actors.length(); i++) {
        final JSONObject c = actors.getJSONObject(i);

        final double g1 = Double.parseDouble(c.getString("gps1"));
        final double g2 = Double.parseDouble(c.getString("gps2"));
        LatLng poss = new LatLng(g1,g2);

        final String title = c.getString("name");
        final String place = c.getString("place");
        final String place2 = c.getString("place2");
        final String perexfull = c.getString("perexfull");
        final String img1 = c.getString("img1");
        final String info = c.getString("info");

        Marker marker = mMap.addMarker(new MarkerOptions().position(poss).title(title).icon(BitmapDescriptorFactory.fromResource(R.drawable.icon)));

        MarkerInfo markerInfo = new MarkerInfo(title, place, place2, perexfull, img1, info);

        mMarkerMap.put(marker, markerInfo);
    }

    //Set this only once:
    mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {

        @Override
        public void onInfoWindowClick(Marker marker) {
            MarkerInfo markerInfo = mMarkerMap.get(marker);


            Intent intent = new Intent(MapsActivity.this, SingleitemView.class);

            intent.putExtra("place", markerInfo.mPlace);
            intent.putExtra("place2", markerInfo.mPlace2);
            intent.putExtra("perexfull", markerInfo.mPerexfull);
            intent.putExtra("name", markerInfo.mTitle);
            intent.putExtra("img1", markerInfo.mImg1);
            intent.putExtra("info", markerInfo.mInfo);
            startActivity(intent);
        }
    });
}

您的思路是正确的，但请参阅我的答案，以获得更干净的解决方案。您不需要为每个数据项单独设置一个HashMap。完美，看起来更好，效果也很好！谢谢解释：）

void createMarkersFromJson(String json) throws JSONException {

    JSONObject jsonObj = new JSONObject(json);
    JSONArray actors = jsonObj.getJSONArray("result");

    for (int i = 0; i < actors.length(); i++) {
        final JSONObject c = actors.getJSONObject(i);

        final double g1 = Double.parseDouble(c.getString("gps1"));
        final double g2 = Double.parseDouble(c.getString("gps2"));
        LatLng poss = new LatLng(g1,g2);

        final String title = c.getString("name");
        final String place = c.getString("place");
        final String place2 = c.getString("place2");
        final String perexfull = c.getString("perexfull");
        final String img1 = c.getString("img1");
        final String info = c.getString("info");

        Marker marker = mMap.addMarker(new MarkerOptions().position(poss).title(title).icon(BitmapDescriptorFactory.fromResource(R.drawable.icon)));

        MarkerInfo markerInfo = new MarkerInfo(title, place, place2, perexfull, img1, info);

        mMarkerMap.put(marker, markerInfo);
    }

    //Set this only once:
    mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {

        @Override
        public void onInfoWindowClick(Marker marker) {
            MarkerInfo markerInfo = mMarkerMap.get(marker);


            Intent intent = new Intent(MapsActivity.this, SingleitemView.class);

            intent.putExtra("place", markerInfo.mPlace);
            intent.putExtra("place2", markerInfo.mPlace2);
            intent.putExtra("perexfull", markerInfo.mPerexfull);
            intent.putExtra("name", markerInfo.mTitle);
            intent.putExtra("img1", markerInfo.mImg1);
            intent.putExtra("info", markerInfo.mInfo);
            startActivity(intent);
        }
    });
}
