意图putextra map android

Question

活动＆lt; - 首先，我想intent.putExtra（数据）......   但它只放了一个标记......   它没有（数据）很多标记???   帮帮我，pllz ??

Marker marker = map.addMarker(new MarkerOptions().icon(BitmapDescriptorFactory.fromBitmap(bmp))
                        .position(new LatLng(dataLat,dataLong)).title(dataTitle)
                        .snippet(dataAddress)); 
                 allMarkersMap.put(marker, DetailActivity.class);

                 map.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {

            @Override
            public void onInfoWindowClick(Marker marker) {
                Class cls = allMarkersMap.get(marker);
                // TODO Auto-generated method stub
                 Intent intent = new Intent(MainActivity.this,cls);

                 intent.putExtra("Title",dataTitle);


                // Toast.makeText(getBaseContext(), phone + "-"+  dataTitle +"-"+ dataAddress + "-" , Toast.LENGTH_SHORT).show();
                 startActivity(intent); 

活动＆lt; - 第二

 Intent intent = getIntent();
tvtitle = (TextView)findViewById(R.id.tvTitle);


        Bundle bundle = intent.getExtras();

        String dataTitle = bundle.getString("Title");
        ((TextView)findViewById(R.id.tvTitle)).setText("Title:   " + dataTitle);



        //  Toast.makeText(getBaseContext(),title, Toast.LENGTH_SHORT).show();
        }
