How to get the position of a dynamically added view relative to its parent

Question

RelativeLayout.LayoutParams imageParams= new RelativeLayout.LayoutParams(200,200);
ImageView mImageView=new ImageView(this);
mImageView.setImageBitmap(bitmap);
viewParent.addView(mImageView, imageParams);

Under my touch event, i log getX, getLeft and leftMargin of my view.

18835-18835/com.android.test E/﹕ getX: 260.49933 getLeft: 0.0 leftMargin: 0.0

Why getLeft and leftMargin return 0? How can i get the view's position relative to its parent?

I added an imageview programmatically into the relative layout. Then I am able to drag and drop the image any where inside the view

06-16 02:43:28.566    2721-2721/com.now.stickit E/﹕ getX: 225.54785getLeft: 0.0leftMargin: 0.0

It will be better to provide image for your question for visualization.

Quoting the documentation:

getLeft ()

Left position of this view relative to its parent.

So you are adding your view inside RelativeLayout and it goes to top, left corner. It is normal behavior and getLeft() and getLeftMargin() will return 0.

How can i get the view's position relative to its parent?

So now your are getting your view position relative to it's parent. Maybe your forget to add some rules on your RelativeLayout.Params?
