移动应用开发：1.使用Android的图形处理的基本操作技能 a)绘制图片500×500,左空隙10dp，在图片底部添上文字“Hello Android” b)绘制点（10，550），（800，1000），点宽50，颜色为黄色； c)绘制绿色线（10，550）到（800，1000），线宽10；红色多线(10,550)到(10,1000), (10,1000)到(800,1000) ， (800,1000)到 (800, 550) ，(800,550)到(10,550) d)绘制矩形，填充色CYAN， (10, 1050, 350, 1500) 2.实现简易订餐系统的菜品详情，同时切入图片的动画特效 a)实现点击菜品项目，启动新的页面，布局包括标题和单价，图片，详情。 b)通过程序实现图片的动画加载效果，效果包含图片中心旋转并放大，持续事件1秒钟。 c)点击图片，弹出图片对话框。图片可以通过双指触屏放大缩小

对于第一个问题，以下是绘制图片、点、线、多线和矩形的代码示例：

public class MyView extends View {
    private Paint mPaint;

    public MyView(Context context) {
        super(context);
        mPaint = new Paint();
        mPaint.setAntiAlias(true);
    }

    @Override
    public void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        // 绘制图片
        Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.image);
        Rect dstRect = new Rect(10, 10, 510, 510);
        canvas.drawBitmap(bitmap, null, dstRect, mPaint);

        // 绘制文字
        mPaint.setTextSize(50);
        mPaint.setColor(Color.BLACK);
        canvas.drawText("Hello Android", 20, 570, mPaint);

        // 绘制点
        mPaint.setColor(Color.YELLOW);
        mPaint.setStrokeWidth(50);
        canvas.drawPoint(10, 550, mPaint);
        canvas.drawPoint(800, 1000, mPaint);

        // 绘制线
        mPaint.setColor(Color.GREEN);
        mPaint.setStrokeWidth(10);
        canvas.drawLine(10, 550, 800, 1000, mPaint);

        // 绘制多线
        mPaint.setColor(Color.RED);
        mPaint.setStrokeWidth(10);
        Path path = new Path();
        path.moveTo(10, 550);
        path.lineTo(10, 1000);
        path.lineTo(800, 1000);
        path.lineTo(800, 550);
        path.lineTo(10, 550);
        canvas.drawPath(path, mPaint);

        // 绘制矩形
        mPaint.setColor(Color.CYAN);
        RectF rectF = new RectF(10, 1050, 350, 1500);
        canvas.drawRect(rectF, mPaint);
    }
}

对于第二个问题，以下是实现简易订餐系统的菜品详情，并切入图片的动画特效的代码示例：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ImageView imageView = findViewById(R.id.image);
        imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                showImageDialog();
            }
        });
    }

    private void showImageDialog() {
        final Dialog dialog = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
        dialog.setContentView(R.layout.dialog_image);
        dialog.setCancelable(true);

        ImageView imageView = dialog.findViewById(R.id.image);
        AnimationSet animationSet = new AnimationSet(true);
        animationSet.addAnimation(new ScaleAnimation(0, 1.2f, 0, 1.2f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f));
        animationSet.addAnimation(new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f));
        animationSet.setDuration(1000);
        animationSet.setFillAfter(true);
        imageView.startAnimation(animationSet);

        imageView.setOnTouchListener(new View.OnTouchListener() {
            private float lastDistance;
            private float lastX;
            private float lastY;
            private int mode = 0;

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction() & MotionEvent.ACTION_MASK) {
                    case MotionEvent.ACTION_DOWN:
                        mode = 1;
                        lastX = event.getX();
                        lastY = event.getY();
                        break;
                    case MotionEvent.ACTION_POINTER_DOWN:
                        mode = 2;
                        lastDistance = getDistance(event);
                        break;
                    case MotionEvent.ACTION_MOVE:
                        if (mode == 2) {
                            float distance = getDistance(event);
                            float scale = distance / lastDistance;
                            imageView.setScaleX(imageView.getScaleX() * scale);
                            imageView.setScaleY(imageView.getScaleY() * scale);
                            lastDistance = distance;
                        } else if (mode == 1) {
                            float x = event.getX();
                            float y = event.getY();
                            float deltaX = x - lastX;
                            float deltaY = y - lastY;
                            imageView.setTranslationX(imageView.getTranslationX() + deltaX);
                            imageView.setTranslationY(imageView.getTranslationY() + deltaY);
                            lastX = x;
                            lastY = y;
                        }
                        break;
                    case MotionEvent.ACTION_UP:
                    case MotionEvent.ACTION_POINTER_UP:
                        mode = 0;
                        break;
                }
                return true;
            }

            private float getDistance(MotionEvent event) {
                float x = event.getX(0) - event.getX(1);
                float y = event.getY(0) - event.getY(1);
                return (float) Math.sqrt(x * x + y * y);
            }
        });

        dialog.show();
    }
}

其中，`R.layout.activity_main` 是包含菜品列表的布局文件，`R.layout.dialog_image` 是包含放大的图片的布局文件。在菜品列表中，每个菜品项都设置了点击事件，点击后会弹出图片对话框。在图片对话框中，图片会执行动画特效并可以通过双指触屏放大缩小。
