我试图在touch of Image上获得x,y坐标,并且我想要执行一些 *** 作.所以,任何人都可以告诉我如何触摸图像的x,y坐标.提前致谢.

我的代码 –

public class MovableObject extends ImageVIEw implements OntouchListener{    Bitmap myBmp;    Paint myPaint = new Paint();    int MoveX = 0;    public MovableObject(Context context,int moveObject,Bitmap myBmp) {        super(context);        super.setClickable(true);        this.myBmp = myBmp;        myPaint.setcolor(color.WHITE);        this.MoveX = moveObject;        setontouchListener(this);    }    @OverrIDe    protected voID onDraw(Canvas canvas) {        super.onDraw(canvas);        canvas.drawBitmap(myBmp, MoveX, 100, myPaint);    }    @OverrIDe    public boolean ontouch(VIEw v, MotionEvent event) {        switch (event.getAction() & MotionEvent.ACTION_MASK) {            case MotionEvent.ACTION_DOWN:                System.out.println("down...."+event.getX()+" "+event.getY());            case MotionEvent.ACTION_MOVE:        }        return true;    }}

通过这个我得到x,y坐标,我点击,但我想得到x,y当我点击我的图像.

解决方法:

MoveX – It is the starting x co-ordinate of your vIEw.
MoveY –
It is the starting y co-ordinate of your vIEw.
imgHeiht – It is the
Height of the Image;
imgWIDth – It is the WIDth of the Image;

event.getX()- It is the actual position of your X co-ordinate.

event.getY()- It is the actual position of your Y co-ordinate.

if(MoveX <= event.getX() && event.getX()<= (MoveX+imgWIDth) && (MoveY <= event.getY() && (event.getY() <= MoveY+imgHeight))){    System.out.println("down...."+event.getX()+" "+event.getY());    }

这可能对你有所帮助.
