Question

看起来我已经创建了一个模仿Google Map API的位置按钮的函数，然后使用onClickListner对其进行了调用。而且效果很好，但是问题是我只能对其进行缩放和放大动画，我希望它像股票按钮一样工作。请提出任何改进或其他任何“更好”的方法来建议我。

这是我的按钮

ImageButton Mylocation = (ImageButton) findViewById(R.id.my_location);
        Mylocation.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

               myPosition();
            }
        });

这是我的功能

 public void myPosition() {
        if (gps.canGetLocation()) {


            latitude = gps.getLatitude();
            longitude = gps.getLongitude();
            // Toast.makeText(getApplicationContext(), "  "+latitude+" "+longitude,Toast.LENGTH_LONG).show();
            Longitude = Double.toString(latitude);
            Latitude = Double.toString(longitude);
        }
        // Add a marker in Sydney and move the camera
        LatLng me = new LatLng(latitude, longitude);
        //MyMarker= mMap.addMarker(new MarkerOptions().position(me).snippet("My Location"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(me));
        CameraUpdate center = CameraUpdateFactory.newLatLng(me);
        CameraUpdate zoom = CameraUpdateFactory.zoomTo(17);
        mMap.moveCamera(center);
        mMap.animateCamera(zoom);

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        mMap.setMyLocationEnabled(true);


    }

我想要的是添加自己的自定义按钮，该按钮指向我的位置，并且还具有缩放和滚动动画（如在股票按钮中一样）

我在自己制作的应用中做了类似的事情。我像这样使用animateCamera和newLatLngZoom：

                mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(YourLat,YourLong),yourZoom);

您可以了解有关CameraUpdateFactory here的更多信息关于animateCamera here

修改

public void myPosition（）{ 如果（gps.canGetLocation（））{

        latitude = gps.getLatitude();
        longitude = gps.getLongitude();
        // Toast.makeText(getApplicationContext(), "  "+latitude+" "+longitude,Toast.LENGTH_LONG).show();
        Longitude = Double.toString(latitude);
        Latitude = Double.toString(longitude);
    }
    // Add a marker in Sydney and move the camera
    LatLng me = new LatLng(latitude, longitude);
    //MyMarker= mMap.addMarker(new MarkerOptions().position(me).snippet("My Location"));

     mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(me),17); //This is where it should be


    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling
        //    ActivityCompat#requestPermissions
        // here to request the missing permissions, and then overriding
        //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
        //                                          int[] grantResults)
        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }
    mMap.setMyLocationEnabled(true);


}
