以下是一个使用Mapbox Android SDK来从GeoJson文件中过滤并只显示具有特定属性的点的示例代码：

1. 首先，确保您已经在您的项目中添加了Mapbox Android SDK的依赖项。可以在build.gradle文件中添加以下行来添加依赖项：

implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:9.6.1'
implementation 'com.mapbox.mapboxsdk:mapbox-android-plugin-annotation-v9:0.9.0'
implementation 'com.mapbox.mapboxsdk:mapbox-android-plugin-annotation-v9:0.9.0'

2. 创建一个Mapbox地图的布局文件（例如，activity_main.xml）：

3. 在您的活动（例如，MainActivity.java）中，设置Mapbox地图并加载GeoJson文件：

import com.mapbox.geojson.Feature;
import com.mapbox.geojson.FeatureCollection;
import com.mapbox.geojson.Point;
import com.mapbox.mapboxsdk.Mapbox;
import com.mapbox.mapboxsdk.maps.MapView;
import com.mapbox.mapboxsdk.maps.MapboxMap;
import com.mapbox.mapboxsdk.maps.OnMapReadyCallback;
import com.mapbox.mapboxsdk.plugins.annotation.Circle;
import com.mapbox.mapboxsdk.plugins.annotation.CircleManager;
import com.mapbox.mapboxsdk.plugins.annotation.CircleOptions;

import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

    private MapView mapView;
    private CircleManager circleManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Mapbox.getInstance(this, "YOUR_MAPBOX_ACCESS_TOKEN");
        setContentView(R.layout.activity_main);

        mapView = findViewById(R.id.mapView);
        mapView.onCreate(savedInstanceState);
        mapView.getMapAsync(new OnMapReadyCallback() {
            @Override
            public void onMapReady(MapboxMap mapboxMap) {
                circleManager = new CircleManager(mapView, mapboxMap, mapboxMap.getStyle());
                loadGeoJsonData();
            }
        });
    }

    private void loadGeoJsonData() {
        try {
            InputStream inputStream = getAssets().open("your_geojson_file.geojson");
            FeatureCollection featureCollection = FeatureCollection.fromJson(inputStream);
            List filteredFeatures = new ArrayList<>();

            // 过滤具有特定属性的点
            for (Feature feature : featureCollection.features()) {
                if (feature.properties() != null && feature.properties().has("your_attribute")) {
                    // 添加具有特定属性的点到过滤后的列表中
                    filteredFeatures.add(feature);
                }
            }

            // 在地图上显示过滤后的点
            for (Feature filteredFeature : filteredFeatures) {
                Point point = (Point) filteredFeature.geometry();
                CircleOptions circleOptions = new CircleOptions()
                        .withLatLng(new LatLng(point.latitude(), point.longitude()))
                        .withCircleColor(ColorUtils.colorToRgbaString(Color.BLUE))
                        .withCircleRadius(5f);
                circleManager.create(circleOptions);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onStart() {
        super.onStart();
        mapView.onStart();
    }

    @Override
    public void onResume() {
        super.onResume();
        mapView.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mapView.onPause();
    }

    @Override
    public void onStop() {
        super.onStop();
        mapView.onStop();
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        mapView.onSaveInstanceState(outState);
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mapView.onLowMemory();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        mapView.onDestroy();
    }
}

请确保将上述代码中的YOUR_MAPBOX_ACCESS_TOKEN替换为您自己的Mapbox访问令牌，并将your_geojson_file.geojson替换为您自己的GeoJson文件名。此外，您可以根据需要修改过滤条件和在地图上显示点的样式。

希望对您有所帮助
