Tracer une ligne entre 2 points en utilisant Google Maps

Question

Mon problème est que je veux créer une méthode que lorsque je l'appelle en lui donnant deux GeoPoint, je veux qu'il trace une ligne entre les deux points et je n'ai pas pu fais ceci.

Merci d'avance.

public class MyOverlays extends ItemizedOverlay<OverlayItem> { 

private ArrayList<OverlayItem> mapOverlays = new ArrayList<OverlayItem>(); 
private Context context; 
private int lastestIndex; 
private Projection projection; 
private Canvas canvas; 
private MapView mapv; 
private boolean shadow; 

public MyOverlays(Context context, Drawable defaultMarker, String player) { 
    super(boundCenterBottom(defaultMarker)); 
    this.context = context; 
} 

@Override 
protected OverlayItem createItem(int i) { 
    return mapOverlays.get(i); 
} 

@Override 
public int size() { 
    return mapOverlays.size(); 

} 

public void setPj(Projection projection) { 
    this.projection = projection; 

} 

public void draw(Canvas canvas, MapView mapv, boolean shadow) { 
    super.draw(canvas, mapv, shadow); 
    this.canvas = canvas; 
    this.mapv = mapv; 
    this.shadow = shadow; 

    // Configuring the paint brush 

} 

Méthode d'essai idéalement je voudrais passer 2 géopoints pour tracer une ligne entre les

public void test() { 
    super.draw(canvas, mapv, shadow); 
    Paint mPaint = new Paint(); 
    mPaint.setDither(true); 
    mPaint.setColor(Color.RED); 
    mPaint.setStyle(Paint.Style.FILL_AND_STROKE); 
    mPaint.setStrokeJoin(Paint.Join.ROUND); 
    mPaint.setStrokeCap(Paint.Cap.ROUND); 
    mPaint.setStrokeWidth(4); 

    GeoPoint gP1 = new GeoPoint(34159000, 73220000);// starting point 
    GeoPoint gP2 = new GeoPoint(33695043, 73050000);// End point Islamabad 

    GeoPoint gP4 = new GeoPoint(33695043, 73050000);// Start point Islamabad 
    GeoPoint gP3 = new GeoPoint(33615043, 73050000);// End Point Rawalpindi 

    Point p1 = new Point(); 
    Point p2 = new Point(); 
    Path path1 = new Path(); 

    Point p3 = new Point(); 
    Point p4 = new Point(); 
    Path path2 = new Path(); 
    projection.toPixels(gP2, p3); 
    projection.toPixels(gP1, p4); 

    path1.moveTo(p4.x, p4.y);// Moving to Abbottabad location 
    path1.lineTo(p3.x, p3.y);// Path till Islamabad 

    projection.toPixels(gP3, p1); 
    projection.toPixels(gP4, p2); 

    path2.moveTo(p2.x, p2.y);// Moving to Islamabad location 
    path2.lineTo(p1.x, p1.y);// Path to Rawalpindi 

    canvas.drawPath(path1, mPaint);// Actually drawing the path from 
            // Abbottabad to Islamabad 
    canvas.drawPath(path2, mPaint);// Actually drawing the path from 
            // Islamabad to Rawalpindi 
    this.populate(); 
}

résolu mon problème,

public void draw(Canvas canvas, MapView mapv, boolean shadow){ 
    super.draw(canvas, mapv, shadow); 
    this.canvas=canvas; 
    this.mapv=mapv; 
    this.shadow=shadow; 
    if(line==1){ 
     Paint mPaint = new Paint(); 
     mPaint.setDither(true); 
     mPaint.setColor(Color.RED); 
     mPaint.setStyle(Paint.Style.FILL_AND_STROKE); 
     mPaint.setStrokeJoin(Paint.Join.ROUND); 
     mPaint.setStrokeCap(Paint.Cap.ROUND); 
     mPaint.setStrokeWidth(4); 

     GeoPoint gP1 = new GeoPoint(34159000,73220000);//starting point Abbottabad 
     GeoPoint gP2 = new GeoPoint(33695043,73050000);//End point Islamabad 

     GeoPoint gP4 = new GeoPoint(33695043, 73050000);//Start point Islamabad 
     GeoPoint gP3 = new GeoPoint(33615043, 73050000);//End Point Rawalpindi 

     Point p1 = new Point(); 
     Point p2 = new Point(); 
     Path path1 = new Path(); 

     Point p3 = new Point(); 
     Point p4 = new Point(); 
     Path path2 = new Path(); 
     projection.toPixels(gP2, p3); 
     projection.toPixels(gP1, p4); 

     path1.moveTo(p4.x, p4.y);//Moving to Abbottabad location 
     path1.lineTo(p3.x,p3.y);//Path till Islamabad 

     projection.toPixels(gP3, p1); 
     projection.toPixels(gP4, p2); 

     path2.moveTo(p2.x, p2.y);//Moving to Islamabad location 
     path2.lineTo(p1.x,p1.y);//Path to Rawalpindi 

     canvas.drawPath(path1, mPaint);//Actually drawing the path from Abbottabad to Islamabad 
     canvas.drawPath(path2, mPaint);//Actually drawing the path from Islamabad to Rawalpindi 
    } 


    //Configuring the paint brush 



    } 
public void test(){ 
    System.out.println("vim ao test"); 
    line=1; 
    draw(canvas,mapv,shadow); 
}
