ポリラインはGoogleマップの宛先に完全ではありません

Question

私は緯度と経度を入力して位置までの距離を計算し、マーカー位置までのポリラインを描くようにしようとしていますが、この私のコード `

public class MainActivity extends AppCompatActivity implements OnMapReadyCallback { 
private TextView source; 
private TextView destination; 
private EditText sLatitude1; 
private EditText sLongtiude1; 
private EditText dLatitude2; 
private EditText dLongtiude2; 
private Button button; 
private GoogleMap mMap; 
boolean mapReady = false; 
MarkerOptions place1; 
MarkerOptions place2; 
Location location; 
double lati1; 
double longi1; 
double lati2; 
double longi2; 
TextView textView; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    // find text that display distance 
    textView = (TextView) findViewById(R.id.distance); 
    MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map); 
    mapFragment.getMapAsync(this); 
    // find edit text and text view 
    source = (TextView) findViewById(R.id.sourc); 
    destination = (TextView) findViewById(R.id.destination); 
    sLatitude1 = (EditText) findViewById(R.id.lat1); 
    sLongtiude1 = (EditText) findViewById(R.id.long1); 
    dLatitude2 = (EditText) findViewById(R.id.lat2); 
    dLongtiude2 = (EditText) findViewById(R.id.long2); 
    // find button 
    button = (Button) findViewById(R.id.getDistance); 

//ここで私はにOnclick

button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      // find string from edittext 
      String lat1 = sLatitude1.getText().toString(); 
      // parse string to double 
      lati1 = ParseDouble(lat1); 
      String lon1 = sLongtiude1.getText().toString(); 
      longi1 = ParseDouble(lon1); 
      String lat2 = dLatitude2.getText().toString(); 
      lati2 = ParseDouble(lat2); 
      String lon2 = dLongtiude2.getText().toString(); 
      longi2 = ParseDouble(lon2); 
      Log.i("**lat", lat2); 
      CameraPosition place = CameraPosition.builder() 
        .target(new LatLng(lati1, longi1)) 
        .zoom(3) 
        .bearing(6) 
        .tilt(45) 
        .build(); 
      flyTo(place); 

      double xy1 = distanceBetween(new LatLng(lati1, longi1), new LatLng(lati2, longi2)); 
      String distanceis = formatNumber(xy1); 
      textView.setText(distanceis); 
      place1= new MarkerOptions().position(new LatLng(lati1,longi1)) 
        .title("i am here").icon(BitmapDescriptorFactory.fromResource(R.drawable.bubble_mask)); 
      place2= new MarkerOptions().position(new LatLng(lati2,longi2)) 
        .title("my destination").icon(BitmapDescriptorFactory.fromResource(R.drawable.bubble_mask)); 



      mMap.addPolyline(new PolylineOptions().geodesic(true) 
        .add(new LatLng(lati1, longi1)) 
        .add(new LatLng(lati2, lati2))); 
      // Add a listener for polyline clicks that changes the clicked polyline's color. 
      mMap.setOnPolylineClickListener(new GoogleMap.OnPolylineClickListener() { 
       @Override 
       public void onPolylineClick(Polyline polyline) { 
        // Flip the values of the red, green and blue components of the polyline's color. 
        polyline.setColor(polyline.getColor()^0x00ffffff); 
       } 
      }); 
      mMap.addCircle(new CircleOptions() 
        .center(new LatLng(lati1, longi1)) 
        .radius(5000) 
        .strokeColor(Color.GREEN) 
        .fillColor(Color.argb(54, 99, 255, 0))); 
      mMap.addCircle(new CircleOptions() 
        .center(new LatLng(lati2, longi2)) 
        .radius(5000) 
        .strokeColor(Color.BLUE) 
        .fillColor(Color.argb(54, 99, 255, 0))); 
      mMap.addMarker(place1); 
      mMap.addMarker(place2); 
     } 

    }); 


} 
    // mehtod to parse double from string 

double ParseDouble(String strNumber) { 
    if (strNumber != null && strNumber.length() > 0) { 
     try { 
      return Double.parseDouble(strNumber); 
     } catch (Exception e) { 
      return -1; // or some value to mark this field is wrong. or make a function validates field first ... 
     } 
    } else return 0; 
} 

// get distance 
public static Double distanceBetween(LatLng point1, LatLng point2) { 
    if (point1 == null || point2 == null) { 
     return null; 
    } 
    double vw = SphericalUtil.computeDistanceBetween(point1, point2); 
    Log.i("distance isby utillib ", String.valueOf(vw)); 
    return vw; 
} 

private String formatNumber(double distance) { 
    String unit = "m"; 
    if (distance < 1) { 
     distance *= 1000; 
     unit = "mm"; 
    } else if (distance > 1000) { 
     distance /= 1000; 
     unit = "km"; 
    } 

    return String.format("%4.3f%s", distance, unit); 
} 
@Override 
public void onMapReady(GoogleMap googleMap) { 
    mapReady = true; 
    mMap = googleMap;} 

にポリラインを追加するには、//私はあなたが間違った方法でポリラインを追加

完了していない理由がわかりません！

mMap.addPolyline(new PolylineOptions().geodesic(true) 
        .add(new LatLng(lati1, longi1)) 
        .add(new LatLng(lati2, lati2))); 

lat2、lat2！

mMap.addPolyline(new PolylineOptions().geodesic(true) 
        .add(new LatLng(lati1, longi1)) 
        .add(new LatLng(lati2, longi2)));
