Hi,
I am new to the android developing world and have what I think is a
very simple question. I have created a circle on a canvas and drawn it
successfully. I now wish to add another circle to this already
existing canvas in a different position. I have defined my x and y as
arguments I pass to custom drawable view but when I try and get
another circle drawn it just replaces the one that was already
present. How do I keep the first circle and add on a second?
(My code below does not show trying to add another circle, it is
simply what works with creating a single colour circle).
Thanks
G
package com.image;
import android.app.Activity;
import android.os.Bundle;
public class image extends Activity {
/** Called when the activity is first created. */
private CustomDrawableView mCustomDrawableView;
//private CustomDrawableView mCustomDrawableView2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//last argument 1 = green, all others = red
mCustomDrawableView = new CustomDrawableView(this, 150, 40,
"green");
setContentView(mCustomDrawableView);
}
}
package com.image;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.drawable.ShapeDrawable;
import android.graphics.drawable.shapes.OvalShape;
import android.view.View;
public class CustomDrawableView extends View {
private ShapeDrawable mDrawable;
public CustomDrawableView(Context context, int x, int y, String
Colour) {
super(context);
//int x = 80;
//int y = 90;
int width = 50;
int height = 50;
mDrawable = new ShapeDrawable(new OvalShape());
if (Colour == "green"){
mDrawable.getPaint().setColor(0xff74AC23);//green
} else if (Colour == "red") {
mDrawable.getPaint().setColor(0xffff0000);//red
}
mDrawable.setBounds(x, y, x + width, y + height);
}
protected void onDraw(Canvas canvas) {
mDrawable.draw(canvas);
}
}
