Adding Bitmap Image into Canvas in Android

Hi,

                    I’m developing  a Maze Game in Android.    I  faced a problem with adding the image into Canvas. Actually I draw the circle by using canvas is working but I need to add the image from drawable.This is for Sample code for draw circle by using canvas….

Paint ball = new Paint();

ball.setTextSize(cellHeight*0.75f);

canvas.drawCircle((currentX * totalCellWidth)+(cellWidth/2),   //x of center

                  (currentY * totalCellHeight)+(cellWidth/2),  //y of center

                  (cellWidth*0.45f), ball);

                   Here  In this place I want add the image into canvas from drawable..

I use the below code for adding image into canvas.but it is not working touch Listener to drawable image.

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.green);

canvas.drawBitmap(bmp,current,currentY ,null);   

                          

            Finally   I got the solution to this touch event functionality for drawable image. Following code I used its working if any other way is their please let me know.

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.green);

       Bitmap img = Bitmap.createScaledBitmap( bmp,25,25, true );

canvas.drawBitmap(img,(currentX * totalCellWidth)+(cellWidth/6) ,(currentY * totalCellHeight)+(cellWidth/6),null);

And In the onTouchEvent method. I use the below code:

public boolean onTouchEvent(MotionEvent event) {

float touchX = event.getX();

float touchY = event.getY();

int currentX = maze.getCurrentX();

int currentY = maze.getCurrentY();

switch (event.getAction() & MotionEvent.ACTION_MASK) {

   case MotionEvent.ACTION_DOWN:

                //touch gesture started

                if(Math.floor(touchX/totalCellWidth) == currentX &&

                Math.floor(touchY/totalCellHeight) == currentY) {

                //touch gesture in the cell where the ball is

                dragging = true;

                return true;

                }

                break;

   case MotionEvent.ACTION_UP:

                //touch gesture completed

                dragging = false;

                return true;

                case MotionEvent.ACTION_MOVE:

                if(dragging) {

                int cellX = (int)Math.floor(touchX/totalCellWidth);

                int cellY = (int)Math.floor(touchY/totalCellHeight);                                                          

                if((cellX != currentX && cellY == currentY) ||

                (cellY != currentY && cellX == currentX)) {

                //either X or Y changed

                boolean moved = false;

                //check horizontal ball movement

        switch(cellX-currentX) {

                case 1:

                moved = maze.move(Maze.RIGHT);

                break;

                case -1:

                moved = maze.move(Maze.LEFT);

                }

                //check vertical ball movement

                switch(cellY-currentY) {

                case 1:

                moved = maze.move(Maze.DOWN);

                break;

                case -1:

                moved = maze.move(Maze.UP);

                }

                if(moved) {

                //the ball was moved so we'll redraw the view

                invalidate();

                if(maze.isGameComplete()) {

                                //game is finished

                                showFinishDialog();

                }

                  }

                          }

                return true;

                      }

                           }

                 return false;

                }
