Fragment doesn't respect match parent height when having listview row item has hidden view in it

I am having a weird issue in my app. In one of my app activity I am inflating three fragments in it with tabs. Everything works fine.
In the fragment in which I am having problem, I have listview which is inflated using adapter and data fro web service. This also works well. Now the problem is this the row which is inflated in adapter, has a hidden view which has visibility=gone in xml. On tap of imageview from that row I make that layout visible through java code. The problem is layout doesn't become visible on tap. I have even set breakpoint on the onClickListener of imageview and it does execute the line which changes the visibility from gone to visible. I am unable to understand what is causing this issue as I am using the same row xml with same data in other screen and there it is working perfectly.
UPDATE
I got to know what's causing this issue but don't know how to solve this. In my activity I am having three fragments. The view that I provided for fragment(in which fragment will be inflated) is causing main problem. I have set height width to match parent but it is not taking match parent height. If the fragment just includes normal views like textview, imageview then also fragment is shown properly.But the problem is if fragment consists of listview, then it only takes height of the custom row that is supplied to the listview. I am able to scroll complete listview in that space.
I don't understand what is causing this behaviour.
My Updated code.

Here are the screenshots of the problem
Comparing both images you can see that the hidden view appears in the space of the single row item and is scroll able completely in that space.

Better upshot were targeted at plus for android developers (Cristophe Beils):
"Your ListView must have its height set to match_parent or a fixed size, not wrap_content.
If you need to add another view fixed at the bottom of the ListView as a footer, you need to put both the ListView and the footer View in a vertical LinearLayout and set layout_height to 0dp and layout_weight to 1 on the ListView so that it takes the remaining vertical space."

Try fillViewPort=true on the list view.. But not sure what why yoi have a scroll view inside a list view.. Could be the issue too.

Try setting match_parent as the height of the listview
I suspect this will force the list view to have a defined height and fix your problem.

Create popup window for each gridview item - Android

I'm developing an Android application for a restaurant for an food ordering system.
In my project,I have a Gridview ,When click on a button on the item in gridview, I want to get a popup window with some textfields,buttons etc.
I got help from this document example
the above document example is working alone as single application.it's just an example for creating basic pop-up window.but I need it on Gridview.
my work -->
instead of above doc's main.xml and PopUpWinndowDemoActivity.java (it's main activity),
I use my grid_single.xml and it's implementation file Grid_single.java.
But it doesn't work for me.When I click on the each item's button,not showing the pop-up window as i hope. So, Please help me to solve this or give me a working example for pop-up window on grid view items.
I have attached my files with this.
waiting for your help,
Thank you!

Thanks in advance

This is working for me, check once
In grid adapter:
public CustomGrid(String[] web, int[] Imageid, Grid_single activity) {
this.Imageid = Imageid;
this.web = web;
this.activity = activity;
}
In getView method of your adapter, keep like this:
grid = inflater.inflate(R.layout.grid_single, null);
TextView textView = (TextView) grid.findViewById(R.id.grid_text);
ImageView imageView = (ImageView) grid.findViewById(R.id.grid_image);
Button btnPopup = (Button) grid.findViewById(R.id.btnPopup);
btnPopup.setOnClickListener(activity);
Grid_single Should implement OnClickListener, and keep like this:
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnPopup:
initiatePopupWindow(web[grid.getPositionForView(v)]);
break;
default:
break;
}
}

You can't access the UI element in onCreateView method - EVER
Use onActivityCreated method , that tell the fragment the activity is fully created and ready to interact.
#Override
public void onActivityCreated(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
ImageView ivAboutUs = (ImageView) view.findViewById(R.id.iv_home_about_us);
ivAboutUs .setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
}

This might be an issue where the touch events never reach the ImageViews because they were absorbed by something else. I ran into something similar where I was trying to put an onClickListener on an Imageview embedded in a list item. No matter how much I clicked on the imageView, something else was eating up the touch events(Most likely the View that makes up the ListView Item. I fixed the problem by changing the ImageView to an ImageButton and setting its background to null (So that the imageButton would look like an imageView and not an image button.) Once I did that, clicking the images worked for me. Try changing your ImageViews to look like this:
<ImageButton
android:id="#+id/iv_home_about_us"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
android:background="#null"
android:src="#drawable/about" />
<ImageView
android:id="#+id/iv_home_search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_alignTop="#+id/iv_home_about_us"
android:layout_marginRight="10dp"
android:background="#null"
android:src="#drawable/search" />
I hope this helps. Good luck.

Click of an ImageView in a list item is not happening properly

I have a ListView, which m using to display the list of questions one at a time. I have used 5 ImageView in a list item i.e. each list item ( question ) has 5 answers.
What I need, is that when I click any of the image then it should first display the black background color of the selected image for say 500 milliseconds and then it should move to next question.
Currently when I click on any list item it's straight away moving to the next question without displaying black background.

When you start the app currentQuestionPosition=0,finalQuestionPosition=9;
in smilyClick you do refreshQuestionList() which is called based on the values stated before.
But this method removes the adapter and creates new, and that causes whole ListView to redraw.

How to disable behind view click event Framelayout

Here i have one view pager activity which has one imageview and 2 overlay bars. there overlay bars i made using android xml file layout itself.
Here my requirement is like that
1) single tap on view pager's imageview first time = show top and bottom rectangle overlaybar.
2) single tap on view pager's imageview second time = hide these overlays.
These both are functions like android gallary view type.
But here when these top and bottom layout bar displays at that time i want to use only buttons click only which buttons are declare within this layout.
But I am not getting success to achieve this thing.
Problems
1) when top or bottom bar is there if i can click on next or previous button than its takes event for behind imageview single tap touch event, And my bar is getting invisible.
2) Only wants declare buttons event only
3) Avoid imageview getting clicked when i touch to overlay bar.
In short when my top and bottom image bar appears at that time no touh event takes place for imageview from top and bottom image bar. I can click on imageview but not making clickable when i click on actually next or previous or share button.
So these are the problems which i am facing, Please help me .

A better way is to set the top and bottom frame to be clickable, with:
android:clickable="true"
Doing so will make sure that the view/frame itself will trap all clicking events, and will not pass it through the view behind it. Note this method works for all layout/view/controls, but many controls (such as buttons) already have this function on by default.

android:clickable="true" for top and bottom bar.
or give each FrameLayout an onClickListener.

just add this to each of your framelayout view containers so that absorb the click:
android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"

By default, some controls have clickable property as true.
But the layout doesn't. For layout, we have to make them explicitly clickable so that it will grab the events of clicks or touches and will not let it pass to background views. This is how we do it:
android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"
Add these lines to all your layouts, so that it will grab/absorb events and will not let it pass to background views.

#gordon1hd1 answer is correct but for those who are still confused, I am adding my layout which contains a FrameLayout as parent and a LinearLayout and twoImageViews as childs.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/scroll_parent"
android:orientation="horizontal" />
<ImageView
android:id="#+id/ivArrowLeft"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:src="#drawable/actionbar_back"
android:layout_gravity="left|center_vertical"
android:background="#3f808080"
android:clickable="true"
/>
<ImageView
android:id="#+id/ivArrowRight"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="4dp"
android:src="#drawable/actionbar_back"
android:layout_gravity="right|center_vertical"
android:background="#3f808080"
android:rotation="180"
android:clickable="true"
/>
</FrameLayout>
Previously, the Linearlayout was also intercepting touch events when either of ImageViews were pressed. Adding android:clickable="true" to both ImageViews resolved the issue.
If you are also facing this type of issue, add android:clickable="true" to the view you want to trap the clicking event.

Simply, Set android:clickable="true" in xml to your foreground view.

imageView.setSingleTapListener(new OnImageViewTouchSingleTapListener() {
#Override
public void onSingleTapConfirmed() {
Log.d("TAG", "setSingleTapListener");
sCounter++;
if (sCounter % 2 == 0) {
mRlTopOverlayBar.setVisibility(View.GONE);
mRlBottomOverlayBar.setVisibility(View.GONE);
pager.requestFocus();
} else {
mRlTopOverlayBar.setVisibility(View.VISIBLE);
mRlBottomOverlayBar.setVisibility(View.VISIBLE);
mRlTopOverlayBar.requestFocus();
mRlBottomOverlayBar.requestFocus();
mRlBottomOverlayBar.setClickable(true);
mRlTopOverlayBar.setClickable(true);
}
}
});

Add android:clickable="true" to rl_bottom_overlay and rl_top_overlay. If you don´t set click events to these layouts (nor via XML neither programatically), no events will be triggered on background views.
