draw object/image on canvas

Question

Is there another way to draw an object on a canvas in android?

This code inside draw() doesn't work:

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.pushpin);
          canvas.drawBitmap(bmp, screenPts.x, screenPts.y-50, null);  

Well actually, it's working on my 1st code but when I've transfered this to another class called MarkOverlay, it's not working anymore.

  markerOverlay = new MarkerOverlay(getApplicationContext(), p);                       listOfOverlays.add(markerOverlay);  

What parameter should I pass to MarkerOverlay to make this code work? The error is somewhere in getResources().

FYI, canvas.drawOval is perfectly working but I really want to draw an Image not an Oval. :)

Answer 1

I prefer to do this as it only generates the image once:

public class CustomView extends View {      private Drawable mCustomImage;      public CustomView(Context context, AttributeSet attrs) {         super(context, attrs);         mCustomImage = context.getResources().getDrawable(R.drawable.my_image);     }      ...      protected void onDraw(Canvas canvas) {         Rect imageBounds = canvas.getClipBounds();  // Adjust this for where you want it          mCustomImage.setBounds(imageBounds);         mCustomImage.draw(canvas);     } }

package com.canvas;  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 Keypaint extends View {     Paint p;      @Override     protected void onDraw(Canvas canvas) {         super.onDraw(canvas);         p=new Paint();         Bitmap b=BitmapFactory.decodeResource(getResources(), R.drawable.icon);         p.setColor(Color.RED);         canvas.drawBitmap(b, 0, 0, p);     }      public Keypaint(Context context) {         super(context);     } }
