Я хотел бы выбрать несколько игроков (выделенных фиолетовыми цветами, т.Е. Игрока 1, игрока 3 и игрока 5) из «MyPlayerActivity» и добавить этих выбранных игроков на карту mapbox в качестве маркеров (MainActivity) при нажатии на кнопку «Добавить игрока». Может кто-нибудь, пожалуйста, помогите мне, как этого добиться?

Ниже приведен мой код MyPlayerActivity

 public class MyPlayerActivity extends ListActivity {

    private static int lastClickId = -1;

    // Array of strings storing country names
    String[] players = new String[] {
            "Player 1",
            "Player 2",
            "Player 3",
            "Player 4",
            "Player 5"            
    };

    // Array of integers points to images stored in /res/drawable-ldpi/
    int[] images = new int[]{
            R.drawable.play_1,
            R.drawable.play_2,
            R.drawable.play_3,
            R.drawable.play_4,
            R.drawable.play_5

    };



    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.list_view);
        final ListView listView = (ListView) findViewById(android.R.id.list);
        View headerView = ((LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.header, null, false);
        getListView().addHeaderView(headerView);


        // Each row in the list stores country name, currency and flag
        List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();

        for(int i=0;i<6;i  ){
            HashMap<String, String> hm = new HashMap<String,String>();
            hm.put("label", ""   players[i]);
            hm.put("imgs", Integer.toString(images[i]) );
            aList.add(hm);
        }

        // Keys used in Hashmap
        String[] from = { "imgs","label"};

        // Ids of views in listview_layout
        int[] to = { R.id.imgs,R.id.label};

        // Instantiating an adapter to store each items
        // R.layout.listview_layout defines the layout of each item
        SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.list_view, from, to);


        // Getting a reference to listview of main.xml layout file


        // Setting the adapter to the listView
        listView.setAdapter(adapter);

        // Item Click Listener for the listview
        AdapterView.OnItemClickListener itemClickListener = new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View container, int position, long id) {

                // Getting the Container Layout of the ListView
                RelativeLayout relativeLayoutParent = (RelativeLayout) container;

                //LinearLayout linearLayoutParent = (LinearLayout) container;

                RelativeLayout relativeLayoutChild = (RelativeLayout) relativeLayoutParent.getChildAt(1);

                // Getting the inner Linear Layout
               // LinearLayout linearLayoutChild = (LinearLayout ) linearLayoutParent.getChildAt(1);

                // Getting the Player TextView
                TextView myPlayer = (TextView) relativeLayoutChild.getChildAt(0);

                Toast.makeText(getBaseContext(), myPlayer.getText().toString(), Toast.LENGTH_SHORT).show();



            }
        };

        // Setting the item click listener for the listview
        listView.setOnItemClickListener(itemClickListener);
    }



}

Following is the list_view.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

        android:paddingEnd="10dp"
        android:paddingRight="10dp"
        android:paddingBottom="10dp" >
    </ImageView>

    <TextView
        android:id="@ id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_centerVertical="true"
        android:text="@ id/label"
        android:textSize="17sp" >
    </TextView>

    <Button
        android:id="@ id/button2"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_marginBottom="10dp"
        android:text="@string/Add_Player"
        android:background="#66ccff"
        android:textColor="#ffffff">
    </Button>


    <ListView android:id="@id/android:list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

Below is the 'MainActivity' code, where I have initialized my map and this is where I would need to add my Player markers and display in mapbox map.


'MainActivity' code where I have initialized my map:

Чтобы добавить маркер на карту, вы можете использовать этот фрагмент:

 mapboxMap.addMarker(new MarkerViewOptions()
                    .position(new LatLng(<position of player>)));
  

Если listview и map находятся в отдельных действиях, вы можете передать информацию о выбранном игроке в действие карты, используя намерение. Это то, что вы искали?
