android – 自定义相对布局缩放？

我正在尝试制作可以缩放和滚动的Custom RelativeLayout.现在我试图达到规模.现在我已将自定义相对布局作为另一个相对布局的父布局,其中包含可触摸的 Imageview作为其子项.现在当我缩放父自定义相对布局时,孩子也会变焦,但Imageview的可点击区域会翻译我不知道为什么？当Imageview或布局处于正常位置时,可点击区域位于Imageview上,但一旦布局变焦,可点击区域就会移动？我不知道为什么我面临奇怪的位置可点击

这是代码

我的自定义相对层面

public class scaleLayout extends RelativeLayout {

    private float mScaleFactor=1.0f;
      private long lastTouchTime = -1;

    public scaleLayout(Context context)
    {
        super(context);

    //  setWillNotDraw(false);

    }

    public scaleLayout(Context context,AttributeSet attrs) {
        super(context,attrs);
        //setWillNotDraw(false);


        // TODO Auto-generated constructor stub
    }


/*  @Override 
    public Boolean dispatchTouchEvent(MotionEvent event) { 
                return super.dispatchTouchEvent(event); 
       } */

    @Override
    public Boolean onTouchEvent(MotionEvent event) {
        // TODO Auto-generated method stub

        return super.onTouchEvent(event);
    }


    @Override
      public Boolean onInterceptTouchEvent(MotionEvent ev) {

        if (ev.getAction() == MotionEvent.ACTION_DOWN) {

          long thisTime = System.currentTimeMillis();
          if (thisTime - lastTouchTime < 250) {

            // Double tap
              mScaleFactor=1.5f;
              invalidate();
            lastTouchTime = -1;

          } else {

            // Too slow :)
            /*  mScaleFactor=1.0f;
              invalidate();*/
            lastTouchTime = thisTime;
          }
        }

        return super.onInterceptTouchEvent(ev);
      }




    @Override
    protected void dispatchDraw(Canvas canvas) {
        // TODO Auto-generated method stub

            canvas.save(Canvas.MATRIX_SAVE_FLAG);
            canvas.scale(mScaleFactor,mScaleFactor);
            super.dispatchDraw(canvas);
            canvas.restore();


    }


    @Override
    public ViewParent invalidateChildInParent(int[] LOCATIOn,Rect dirty) {
        // TODO Auto-generated method stub
        return super.invalidateChildInParent(LOCATIOn,dirty);
    }

    protected void onLayout(Boolean changed,int l,int t,int r,int b)
    {
        int count = getChildCount();
        for(int i=0;i<count;i++){
            View child = getChildAt(i); 
            if(child.getVisibility()!=GONE){
                RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)child.getLayoutParams();
                child.layout(
                    (int)(params.leftMargin * mScaleFactor),(int)(params.topMargin * mScaleFactor),(int)((params.leftMargin + child.getMeasuredWidth()) * mScaleFactor),(int)((params.topMargin + child.getMeasuredHeight()) * mScaleFactor) 
                    );
            }
        }
    }

这是活动

public class LayoutZoomingActivity extends Activity implements OnTouchListener {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.main);
        ImageView img1 = (ImageView) findViewById(R.id.imageView1);
        img1.setOnTouchListener(this);
        ImageView img2 = (ImageView) findViewById(R.id.imageView2);
        img2.setOnTouchListener(this);

    }

    @Override
    public Boolean onTouch(View v,MotionEvent event) {
        // TODO Auto-generated method stub

        ImageView iv= (ImageView) v;
        v.setVisibility(View.INVISIBLE);


        return false;
    }

这是xml
