    <p>I have made a <code>PopupWindow</code> that pops up when a user selects an item in a list. And then when he swipes left and right on the popup window, the data (in the popup) is change to the previous and next items in the list, respectively.</p> <p>And I have made it so that it looks like a new popup window is sliding in from the left as the current one goes out from the right of the screen when the user slides his finger to the right ("Next" motion). And vice versa for the "Previous" motion.</p> <p>But the issue is, as I have made 2 styles for the two animations (left-to-middle while middle-to-right and right-to-middle while middle-to-left), and as <code>PopupWindow</code>s does not get updated while it is showing, when the user swipes to the right ("Next") and then to the left ("Previous"), the animation looks choppy as the 2 animations overlap. The same happens when the swipes are reversed again.</p> <p>Now, if I call <code>update()</code> after changing the Animation, then it again slides in to the middle. That's even worse. So is there anything I can do to achieve the behavior I want?</p> <p>Thanks.</p> <p><strong>EDIT: Source Code</strong></p> <p>Here is the code I used to show the popup for the first time:</p> <pre><code>popup1 = new PopupWindow(popupLayout, popup_width, popup_height, true); popup1.setAnimationStyle(R.style.AnimationPopup); popup1.showAtLocation(this.findViewById(R.id.main_container), Gravity.CENTER, 0, 0); </code></pre> <p>And this is the <code>next()</code> method's code:</p> <pre><code>if(popup2 != null) popup1 = popup2; if(popup1 != null) { popup2 = new PopupWindow(popupLayout, popup_width, popup_height, true); popup2.setAnimationStyle(R.style.AnimationPopup); popup1.dismiss(); popup2.showAtLocation(rootLayout, Gravity.CENTER, 0, 0); } </code></pre> <p>And this is the <code>prev()</code> method's code:</p> <pre><code>if(popup2 != null) popup1 = popup2; if(popup1 != null) { popup2 = new PopupWindow(popupLayout, popup_width, popup_height, true); popup2.setAnimationStyle(R.style.AnimationPopupReverse); popup1.setAnimationStyle(R.style.AnimationPopupReverse); popup1.dismiss(); popup2.showAtLocation(rootLayout, Gravity.CENTER, 0, 0); } </code></pre> <p>That's all for the Java code. The <code>AnimationPopup</code> is a XML with a simple <em>show</em> of slide-from-right-to-center and a <em>hide</em> of slide-from-center-to-left animations. And the <code>AnimationPopupReverse</code> is the reverse of the above animations.</p> <p>I have provided my first try of the codes. Here, the changed animations take effect <em>after</em> one more popup has been shown.</p>

    1. COif you want only slide animation then you can inflate View Pager in Pop Up Window.

    2. CO@ShreeshaS As I have stated in my question, I _have_ got the slide working, but the animation should be reversed dynamically depending on the swipe (gesture) direction. Otherwise, it works fine.

    3. COSo the problem you're experiencing is only about performances? How did you get animations and popupwindows work together? I think you should post some code in order to give some more detail.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
