android - For 语句仅在使用 Intent 传递数据时返回最后一个数据

Question

我想使用 Intents 在 Activity 之间传递数据。我已经可以发送数据了，但问题是数据只包含最后一项。

我不确定，但我认为问题出在基于以下引用的 for 语句:

• > Parsing JSON to custom ArrayList, only returning last item?
• > Listview only displaying last item of arraylist

这是我的代码。我希望有人能帮助解决我的问题。

private void getAllDataLocation() {
    loading = ProgressDialog.show(this, null, "Menampilkan Semua Tempat...", true, false);

    mApiService.getAllPartner().enqueue(new Callback<ResponsePartner>() {
        @Override
        public void onResponse(Call<ResponsePartner> call, Response<ResponsePartner> response) {
            if (response.isSuccessful()) {
                loading.dismiss();

                final List<PlaceItem> placeItems = response.body().getAllPlace();
                initMarker(placeItems);

            } else {
                loading.dismiss();
                Toast.makeText(mContext, "Gagal Mengambil Data Semua Tempat", Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onFailure(Call<ResponsePartner> call, Throwable t) {
            loading.dismiss();
            Toast.makeText(mContext, "Koneksi Internet Bermasalah", Toast.LENGTH_SHORT).show();
        }
    });
}

和

private void initMarker(final List<PlaceItem> listData) {
    //for each semua data dan tampilkan markernya
    for (int i = 0; i < listData.size(); i++) {
        final int finall = i;
        //set latlng nya
        LatLng marker_location = new LatLng(Double.parseDouble(listData.get(i).getLatitude()), Double.parseDouble(listData.get(i).getLongitude()));
        //tambah markernya
        marker_bg.setColorFilter(getResources().getColor(R.color.marker_primary));
        MarkerOptions markerOptions = new MarkerOptions().title(listData.get(i).getName()).position(marker_location);
        markerOptions.icon(BitmapDescriptorFactory.fromBitmap(Tools.createBitmapFromView(ActivityMaps.this, marker_view)));
        mMap.addMarker(markerOptions);
        //start for marker specific zoom ex: for specific city you want to zoom
        LatLng marker_zoom_specific = new LatLng(Constant.city_lat, Constant.city_lng);
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(marker_zoom_specific, 12));
        mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
            @Override
            public void onInfoWindowClick(Marker marker) {
                String id = listData.get(finall).getId();
                String cityName = listData.get(finall).getCityName();
                String description = listData.get(finall).getDescription();
                String address = listData.get(finall).getAddress();
                String phone = listData.get(finall).getPhone();
                String website = listData.get(finall).getWebsite();
                String logo = listData.get(finall).getLogo();
                String toolbarTitle = listData.get(finall).getName();
                String latitude = listData.get(finall).getLatitude();
                String longitude = listData.get(finall).getLongitude();

                Intent toDetail = new Intent(ActivityMaps.this, ActivityPlaceDetail.class);
                toDetail.putExtra(Constant.KEY_ID_PARTNER, id);
                toDetail.putExtra(Constant.KEY_NAME, toolbarTitle);
                toDetail.putExtra(Constant.KEY_CITY_NAME, cityName);
                toDetail.putExtra(Constant.KEY_DESCRIPTION, description);
                toDetail.putExtra(Constant.KEY_ADDRESS, address);
                toDetail.putExtra(Constant.KEY_PHONE, phone);
                toDetail.putExtra(Constant.KEY_WEBSITE, website);
                toDetail.putExtra(Constant.KEY_LOGO, logo);
                toDetail.putExtra(Constant.KEY_LATITUDE, latitude);
                toDetail.putExtra(Constant.KEY_LONGITUDE, longitude);
                startActivity(toDetail);
            }
        });
    }
}

传递整个类对象比传递单个键值对更好。

     PlaceItem placeItem = listData.get(finall).getId();
     intent.putExtra("data", placeItem);

确保您的 PlaceItem 实现了Serializable

当你 getIntent 使用:

    Intent intent = getIntent();
    PlaceItem placeItem = (PlaceItem) intent.getSerializableExtra("data");
    String id = placeItem.getId();
    String cityName = placeItem.getCityName();

等等..
