android osmdroid批量添加不同的标记和弹窗不同的标记用不同的图片展示 给出详细代码

以下是使用osmdroid批量添加不同的标记和弹窗的详细代码：

1. 添加依赖项

在build.gradle文件中添加以下依赖项：

dependencies {
    implementation 'org.osmdroid:osmdroid-android:6.1.5'
    implementation 'org.osmdroid:osmdroid-mapsforge:6.1.5'
}

2. 准备标记图片和数据

在drawable文件夹中添加不同的标记图片，如marker1.png、marker2.png等。

准备需要展示的数据，例如一个列表List myDataList，其中MyData类包含经纬度、标题和内容等属性。

3. 创建MapView和MapController对象

在布局文件中添加MapView控件，创建MapView和MapController对象：

private MapView mapView;
private MapController mapController;

mapView = findViewById(R.id.map_view);
mapView.setTileSource(TileSourceFactory.MAPNIK);
mapView.setBuiltInZoomControls(true);
mapController = mapView.getController();
mapController.setZoom(12.0);

4. 添加标记和弹窗

遍历myDataList列表，创建OverlayItem对象，设置经纬度、标题、内容和标记图片等属性，将OverlayItem添加到ItemizedIconOverlay对象中，最后将ItemizedIconOverlay对象添加到MapView中：

ItemizedIconOverlay<OverlayItem> itemizedIconOverlay = new ItemizedIconOverlay<>(new ArrayList<OverlayItem>(), null, null);

for (MyData myData : myDataList) {
    GeoPoint geoPoint = new GeoPoint(myData.getLatitude(), myData.getLongitude());
    OverlayItem overlayItem = new OverlayItem(myData.getTitle(), myData.getContent(), geoPoint);
    Drawable marker = getResources().getDrawable(R.drawable.marker1);
    overlayItem.setMarker(marker);
    itemizedIconOverlay.addItem(overlayItem);
}

mapView.getOverlays().add(itemizedIconOverlay);

此外，还可以添加弹窗的点击事件，当用户点击标记时弹出弹窗展示更多信息：

itemizedIconOverlay.setOnItemGestureListener(new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
    @Override
    public boolean onItemSingleTapUp(int index, OverlayItem item) {
        new AlertDialog.Builder(MainActivity.this)
                .setTitle(item.getTitle())
                .setMessage(item.getSnippet())
                .setPositiveButton("OK", null)
                .show();
        return true;
    }

    @Override
    public boolean onItemLongPress(int index, OverlayItem item) {
        return false;
    }
});

完整代码如下所示：

public class MainActivity extends AppCompatActivity {
    private MapView mapView;
    private MapController mapController;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mapView = findViewById(R.id.map_view);
        mapView.setTileSource(TileSourceFactory.MAPNIK);
        mapView.setBuiltInZoomControls(true);
        mapController = mapView.getController();
        mapController.setZoom(12.0);

        List<MyData> myDataList = prepareData();

        ItemizedIconOverlay<OverlayItem> itemizedIconOverlay = new ItemizedIconOverlay<>(new ArrayList<OverlayItem>(), null, null);

        for (MyData myData : myDataList) {
            GeoPoint geoPoint = new GeoPoint(myData.getLatitude(), myData.getLongitude());
            OverlayItem overlayItem = new OverlayItem(myData.getTitle(), myData.getContent(), geoPoint);
            Drawable marker = getResources().getDrawable(R.drawable.marker1);
            overlayItem.setMarker(marker);
            itemizedIconOverlay.addItem(overlayItem);
        }

        itemizedIconOverlay.setOnItemGestureListener(new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
            @Override
            public boolean onItemSingleTapUp(int index, OverlayItem item) {
                new AlertDialog.Builder(MainActivity.this)
                        .setTitle(item.getTitle())
                        .setMessage(item.getSnippet())
                        .setPositiveButton("OK", null)
                        .show();
                return true;
            }

            @Override
            public boolean onItemLongPress(int index, OverlayItem item) {
                return false;
            }
        });

        mapView.getOverlays().add(itemizedIconOverlay);
    }

    private List<MyData> prepareData() {
        List<MyData> myDataList = new ArrayList<>();
        myDataList.add(new MyData(39.9139, 116.3917, "Marker 1", "Content 1"));
        myDataList.add(new MyData(39.9145, 116.3921, "Marker 2", "Content 2"));
        myDataList.add(new MyData(39.9132, 116.3932, "Marker 3", "Content 3"));
        myDataList.add(new MyData(39.9125, 116.3918, "Marker 4", "Content 4"));
        myDataList.add(new MyData(39.9128, 116.3929, "Marker 5", "Content 5"));
        return myDataList;
    }

    private static class MyData {
        private double latitude;
        private double longitude;
        private String title;
        private String content;

        public MyData(double latitude, double longitude, String title, String content) {
            this.latitude = latitude;
            this.longitude = longitude;
            this.title = title;
            this.content = content;
        }

        public double getLatitude() {
            return latitude;
        }

        public void setLatitude(double latitude) {
            this.latitude = latitude;
        }

        public double getLongitude() {
            return longitude;
        }

        public void setLongitude(double longitude) {
            this.longitude = longitude;
        }

        public String getTitle() {
            return title;
        }

        public void setTitle(String title) {
            this.title = title;
        }

        public String getContent() {
            return content;
        }

        public void setContent(String content) {
            this.content = content;
        }
    }
}
