Question

我正在尝试显示数组列表中的数据但是在标记点击之后它只显示材料对话框中数组列表中的最后一个元素 DriverLocationDataManager获取数据库中驱动程序的地理位置的所有数据快照

添加所有驱动程序数据后，我使用addMarker函数获取地理位置并在地图上设置标记。

//Init data manager

    drivers = new ArrayList<>(0);



    dataManager = new DriverLocationDataManager(this) {
        @Override
        public void onDataLoaded(List<Driver> data) {
            if (data.isEmpty()) {
                Snackbar.make(container, "Sorry!. UG Shuttle service is currently unavailable",
                        Snackbar.LENGTH_INDEFINITE).show();
            } else {

                drivers.addAll(data);


                List<Marker> markers = addMarkers(data);
                for (int i = 0; i < markers.size(); i++){
                    markers.get(i);
                    Driver driver = drivers.get(i);
                    map.setOnMarkerClickListener(marker -> {
                        // Get custom view
                        View v = getLayoutInflater().inflate(R.layout.driver_popup, null, false);

                        //Assign props
                        TextView username = v.findViewById(R.id.driver_username);
                        CircularImageView profile = v.findViewById(R.id.driver_profile);
                        ImageView status = v.findViewById(R.id.driver_status);
                        TextView shuttle = v.findViewById(R.id.driver_bus_number);
                        ViewGroup viewGroup = v.findViewById(R.id.group);

                        //Init props
                        Glide.with(getApplicationContext())
                                .load(driver.getProfile())
                                .apply(RequestOptions.circleCropTransform())
                                .apply(RequestOptions.placeholderOf(R.drawable.avatar_placeholder))
                                .apply(RequestOptions.errorOf(R.drawable.avatar_placeholder))
                                .apply(RequestOptions.diskCacheStrategyOf(DiskCacheStrategy.AUTOMATIC))
                                .transition(withCrossFade())
                                .into(profile);

                        username.setText(driver.getDriver());   //Driver's username
                        shuttle.setText(driver.getCarNumber()); //Driver's car number

                        //Attach to dialog
                        Builder materialDialog = new Builder(HomeActivity.this)
                                .customView(v, true)
                                .negativeText("Dismiss")
                                .onPositive((dialog, which) -> {
                                    dialog.dismiss();
                                    enableTracking(marker);
                                })
                                .onNegative((dialog, which) -> dialog.dismiss());

                        if (driver.isStatus()) {
                            status.setImageResource(android.R.color.holo_green_light);  //Online

                            //Enable tracking when driver is online
                            materialDialog.positiveText("Track")
                                    .onPositive((dialog, which) -> {
                                        dialog.dismiss();
                                        enableTracking(marker);
                                    });
                        } else {
                            //Tracking is disabled
                            status.setImageResource(android.R.color.holo_red_light);    //Offline
                        }

                        materialDialog.build().show();
                        return true;
                    });



                }
            }
        }
    };

我邀请您阅读官方开发者指南here。它解释了如何正确使用Dialogs，如何在其中显示列表，甚至如何在需要显示列表时实现自定义视图。

对话框仅显示数组列表中的最后一项
