adding onTap method on path direction between 2 point
- by idham
I have a problem in my Android application
I have a path direction on my application and I want to add an onTap method for the path, so if I touch that path my application will display information with alert dialog.
This my activity code:
hasilrute hr = new hasilrute();
for (int k = 0;k < hr.r2.size(); k++){
String angkot = hr.r2.get(i).angkot;
Cursor c = db.getLatLong(hasilrute.a);
Cursor cc = db.getLatLong(hasilrute.b);
String x = (c.getString(3)+","+c.getString(2));
String xx = (cc.getString(3)+","+cc.getString(2));
String pairs[] = getDirectionData(x, xx);
String[] lnglat = pairs[0].split(",");
GeoPoint point = new GeoPoint((int) (Double.parseDouble(lnglat[1]) *1E6),(int)(Double.parseDouble(lnglat[0]) * 1E6));
GeoPoint gp1;
GeoPoint gp2 = point;
for (int j = 1;j < pairs.length; j++){
lnglat = pairs[j].split(",");
gp1 = gp2;
gp2 = new GeoPoint((int) (Double.parseDouble(lnglat[1]) *1E6),(int) (Double.parseDouble(lnglat[0]) * 1E6));
mapView.getOverlays().add(new jalur(gp1, gp2,angkot));
}
}
and it's my jalur.java code
public class jalur extends Overlay {
private GeoPoint gp1;
private GeoPoint gp2;
private String angkot;
private Context mContext;
public jalur(GeoPoint gp1, GeoPoint gp2, String angkot){
this.gp1 = gp1;
this.gp2 = gp2;
this.angkot = angkot;
}

boolean shadow, long when){
