小猴子摘桃android程序代码

在Android中，编写一个简单的"小猴子摘桃"（Monkey Pick Fruit）程序通常会涉及到游戏逻辑、用户界面和事件处理。以下是一个基础的示例代码，使用了Android的`SurfaceView`和`Canvas`来创建一个简单的游戏场景：

// 导入必要的包
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.view.SurfaceHolder;
import android.view.SurfaceView;

public class MonkeyPickFruit extends SurfaceView implements SurfaceHolder.Callback {
    // 声明变量
    private Monkey monkey;
    private int fruitX, fruitY;
    private int monkeySpeed = 5;
    private Paint paint;

    public MonkeyPickFruit(Context context) {
        super(context);
        init();
    }

    public MonkeyPickFruit(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MonkeyPickFruit(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    private void init() {
        getHolder().addCallback(this);
        paint = new Paint();
        paint.setColor(Color.RED); // 猴子和水果的颜色
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        // 创建猴子对象
        monkey = new Monkey(getWidth() / 2, getHeight() / 2);
        fruitX = (int) (Math.random() * (getWidth() - monkey.getWidth()));
        fruitY = (int) (Math.random() * (getHeight() - monkey.getHeight()));
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {}

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {}

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        canvas.drawCircle(monkey.getX(), monkey.getY(), monkey.getWidth() / 2, paint); // 绘制猴子
        canvas.drawCircle(fruitX, fruitY, 20, paint); // 绘制水果
        // 更新猴子位置
        monkey.move(monkeySpeed);
        if (monkey.isColliding(fruitX, fruitY)) {
            // 如果碰撞，重置位置并生成新的水果
            monkey.resetPosition();
            fruitX = (int) (Math.random() * (getWidth() - monkey.getWidth()));
            fruitY = (int) (Math.random() * (getHeight() - monkey.getHeight()));
        }
    }
}

class Monkey {
    // ...定义猴子类，包含位置、移动方法等
}

class Fruit {
    // ...定义水果类，包含碰撞检测方法
}
