Hi,
thanks for ur reply ... Right now, this is the code i have
This is the activity i have written :
package hari.image;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.os.Bundle;
import android.widget.ImageView;
public class imageexp extends Activity {
over drawView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Paint paint1=new Paint();
drawView = new over(this);
drawView.setBackgroundColor(Color.BLACK);
setContentView(drawView);
}
}
This is the class that actually displayes an image of a map n draws a
line over it...
package hari.image;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.View;
public class over extends View {
Paint paint = new Paint();
Paint paint1=new Paint();
public over(Context context) {
super(context);
paint.setColor(Color.RED);
paint.setAlpha(255);
paint.setStrokeWidth(3);
paint1.setAlpha(230);
}
@Override
public void onDraw(Canvas canvas) {
canvas.drawLine(100, 100, 250, 250, paint);
//canvas.drawCircle(150, 200, 3, paint)
Bitmap bit = BitmapFactory.decodeResource(getResources(),
R.drawable.map);
canvas.drawBitmap(bit,30,30,paint1);
}
}
Here,i have drawn the line at some random co-ordinate... Instead,i
want to draw the line in some co-ordinate... This co-ordinate must be
specified by the Activity .... Can u please tell me what i should do
now ??
