Question

现在，我的应用可以搜索地点，当我搜索地点时，它们会在现场标记。但是我想让用户确认他们是否真的要在那里做标记。搜索时，是否有一种方法可以在标记上显示带有“否”复选框的弹出信息？我知道单击标记时会有一个默认的信息窗口。但是我想在信息窗口上做一个按钮，例如“您想在这里做一个标记吗？”问题，那里有一个是或否按钮。另外，如果我可以制作popupinfo之类的东西，我想想一种方法来在用户想要删除标记时有什么想法吗？

这是我的Java代码

package com.example.yoons.honey;


public class RealMap extends AppCompatActivity implements OnMapReadyCallback, GoogleMap.OnMarkerClickListener {

private Button searchButton;
GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.real_map);
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
    mapFragment.getMapAsync((OnMapReadyCallback) this);

    searchButton = new Button(this);
    searchButton.setOnClickListener(search);
}


@Override
public void onMapReady(GoogleMap googleMap) {
    mMap =googleMap;
    mMap.setOnMarkerClickListener(this);
    /*LatLng sydney = new LatLng(-33.852, 151.211);
    googleMap.addMarker(new MarkerOptions().position(sydney)
            .title("Marker in Sydney"));
    googleMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));*/
}

private  View.OnClickListener search=new View.OnClickListener(){ //검색버튼
    public void onClick(View v){
        onMapSearch(v);
    }
};


public void onMapSearch(View view) {
    int markercount=0;//주소개수 사용
    EditText locationSearch = (EditText) findViewById(R.id.editText);
    String location = locationSearch.getText().toString();
    List<Address> addressList = null;
    if (location != null || !location.equals("")) {
        Geocoder geocoder = new Geocoder(this);
        try {
            addressList = geocoder.getFromLocationName(location, 1);

        } catch (IOException e) {
            e.printStackTrace();
        }


        if (addressList != null && addressList.size() != 0) {
            Address address = addressList.get(0);
            LatLng latLng = new LatLng(address.getLatitude(), address.getLongitude());
            mMap.addMarker(new MarkerOptions().position(latLng).title("Marker")/*.draggable(true)*/);
            markercount++;

           // mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
            mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 15f));
        } else {
            Toast.makeText(getApplicationContext(), "location not found", Toast.LENGTH_SHORT).show();
        }

    }

}

@Override
public boolean onMarkerClick(Marker marker) {

    return false;
}

}

Query query = new Query.Builder()
                      .addFilter(Filters.eq(SearchableField.TITLE, "HelloWorld.txt"))
                      .build();

Task<MetadataBuffer> queryTask = getDriveResourceClient().query(query);

此行执行添加标记操作。因此，您可以做的是创建alertdialog并在onclicklistener中处理“是”。

mMap.addMarker(new MarkerOptions().position(latLng).title("Marker")

并在您的onMapSearch函数中，像这样构建警报对话框。

DialogInterface.OnClickListener dialogClickListener = new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch (which){
        case DialogInterface.BUTTON_POSITIVE:
            //Yes button clicked
            mMap.addMarker(new MarkerOptions().position(latLng).title("Marker");
            markercount++;

       // mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 15f));
        break;

    case DialogInterface.BUTTON_NEGATIVE:
        //No button clicked
        break;
    }
} 
};
