我建议你使用Android Dev网站上的“缩放视图”示例

这很简单，效果很好！

我可以在这里用PopupWindow

第1步：

your_main_imageview.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(final View anchorView) {
View popupView = getLayoutInflater().inflate(
                                    R.layout.popup_layout, null);
//Note: Add an imageView in this popup_layout.
ImageView image_button = (ImageView) popupView
                                    .findViewById(R.id.your_imageview);
//Set image for imageView here
PopupWindow popupWindow = new PopupWindow(popupView,
                                    LayoutParams.MATCH_PARENT,
                                    LayoutParams.MATCH_PARENT);
// If the PopupWindow should be focusable
                            popupWindow.setFocusable(false);
                            popupWindow.setOutsideTouchable(false);
                            // If you need the PopupWindow to dismiss when when
                            // touched outside
                            popupWindow
                                    .setBackgroundDrawable(new ColorDrawable());

                            final int location[] = new int[2];

                            // Get the View's(the one that was clicked in the
                            // Fragment) location
                            anchorView.getLocationOnScreen(location);
anchorView.post(new Runnable() {

                                @Override
                                public void run() {
                                    // Using location, the PopupWindow will be
                                    // displayed right under anchorView
                                    popupWindow.showAtLocation(
                                            anchorView,
                                            Gravity.NO_GRAVITY,
                                            location[0],
                                            location[1]
                                                    + anchorView.getHeight());
                                }
                            });


}
