Java Intersect方法不工作，继续返回true

我的intersect方法不断返回true，并将我的分数文本设置为在图像不发生碰撞时检测到的intersect，而是在仿真器启动后立即更改文本。如果需要更多代码，请通知我，并在10分钟内检查。谢谢-这是我所有的代码，冲突代码从第163行开始，我的冲突代码有问题，因为没有检测到冲突，我应该怎么做来修复我的冲突代码

这是我的密码：

public class MainActivity extends AppCompatActivity {



//Layout
private RelativeLayout myLayout = null;

//Screen Size
private int screenWidth;
private int screenHeight;

//Position
private float ballDownY;
private float ballDownX;

//Initialize Class
private Handler handler = new Handler();
private Timer timer = new Timer();

//Images

private ImageView ball = null;

//for net movement along x-axis

@Override

    super.onCreate(savedInstanceState);


    setContentView(R.layout.activity_main);
    myLayout = (RelativeLayout) findViewById(R.id.myLayout);

    //score
    TextView score = (TextView) findViewById(R.id.score);


    //imageviews
    net = (ImageView) findViewById(R.id.net);
    ball = (ImageView) findViewById(R.id.ball);




    //retrieving screen size
    WindowManager wm = getWindowManager();
    Display disp = wm.getDefaultDisplay();
    Point size = new Point();
    disp.getSize(size);
    screenWidth = size.x;
    screenHeight = size.y;

    //move to out of screen
    ball.setX(-80.0f);
    ball.setY(screenHeight + 80.0f);





    //start timer
    timer.schedule(new TimerTask() {
        @Override
        public void run() {
            handler.post(new Runnable() {
                @Override
                public void run() {
                    changePos();
                }
            });
        }
    }, 0, 20);
}

public void changePos() {
    //down

    ballDownY += 10;
    if (ball.getY() > screenHeight) {
        ballDownX = (float) Math.floor((Math.random() * (screenWidth - 
ball.getWidth())));
        ballDownY = -100.0f;

    }
    ball.setY(ballDownY);
    ball.setX(ballDownX);




    /*INTERSECT METHOD
    Rect rc1 = new Rect();
    net.getDrawingRect(rc1);
    Rect rc2 = new Rect();
    ball.getDrawingRect(rc2);
    if (Rect.intersects(rc1, rc2)) {

    TextView score = (TextView) findViewById(R.id.score);
    score.setText("INTERSECT DETECTED");

    }*/




    //make net follow finger
    myLayout.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent event) {
            MainActivity.this.x = event.getX();
            y = event.getY();

            if (event.getAction() == MotionEvent.ACTION_MOVE) {
                net.setX(MainActivity.this.x);
                net.setY(y);



            }
            return true;
        }


    });

}


public boolean Collision(ImageView net, ImageView ball)
{
    Rect AR = new Rect();
    net.getHitRect(AR);
    Rect BR = new Rect();
    ball.getHitRect(BR);
    Render();
    return AR.intersect(BR) || AR.contains(BR) || BR.contains(AR);
}

public void Render()
{
    if(Collision(net, ball))
    {
        points++;
        TextView score = (TextView)findViewById(R.id.score);
        score.setText("Score:" + points);
    }
}



}

大概是这样的：

boolean collision = net.getRect().intersect(ball.getRect());

碰撞是一个布尔值

if(boolean) //Action

然后

我已修改了您的代码，请立即尝试

有很多方法可以做到这一点，最简单的方法是获取每个位图的边界矩形，并在每个时间步上使用Rect.intersect方法检查碰撞。然后使用ifCollisionnet，ballNow，检查我的帖子的结尾。我刚刚编辑了你的问题，现在试一试为什么要在布尔合并中调用布尔冲突？@NBAMIXTAPE3 mmmmmmm，网和球是什么样的控件？@NBAMIXTAPE3 imageview？我明白了，然后我会创建另一个方法，因为如果它们是图像，然后他们在一个图像视图中谢谢你让我非常接近解决这个问题检查我最近的编辑hector，非常感谢你的辛勤工作哇，你是多么的有才华，除了第126行之外一切看起来都很好-这个.x-->无法解决符号和这个.y有同样的错误Héctor Manuel Martinez Durán@NBAMIXTAPE3,好啊cheking@NBAMIXTAPE3现在试试看赫克托·曼努埃尔·马丁内斯·杜兰（Manuel Martinez Durán）仍然不工作，但我在@override boolean Ontouch上添加了公共浮动，这似乎解决了问题，但现在imageview球不会从屏幕顶部掉下来，imageview球甚至不再出现在模拟器上
