在RelativeLayout内部移动ImageView

Question

I need to move an ImageView (or anything else, for that matter) around inside a RelativeLayout. Does any one know the proper way to do this?

Answer 1

Makesure ImageView 's layout_height and layout_width is set to fill_parent . Then do:

To move a view, use Matrix . It is very handy.

Matrix matrix = new Matrix();

matrix.reset();

matrix.postTranslate(x, y);

imageview.setScaleType(ScaleType.MATRIX);
imageview.setImageMatrix(matrix);

Answer 2

我找到了这个：

imageview.layout(l,t,r,b);

Answer 3

mImageView.scrollBy（xOffset，yOffset）;

Answer 4

It is very easy. You can implement onTouchListener event of any control you want and set its x, y position like make a new LayoutParams set its x, y and assign to view as view.setLayoutParam(layoutParams); it will drag the View.
