this is my question yearwise activity(from this I launched the fragment activity)

protected void onCreate (Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.question_yearwise);
Button btn2018ii = (Button)findViewById(R.id.btn2018ii);

public void onClick(View v) {

MyServerData2018ii.getInstance().setTestState("inProgress");
startActivity(Quiz2018ii);
}
});
}
}

Replace the method like this,
mainView.findViewById(R.id.check_results).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});

Your activity is recreated on rotation.
The fragment manager stores the original fragment in the instance state, but I assume you are adding a new fragment in the onCreate() of the activity.
So you have the restored and the new fragment on top of each other.
Perhaps only add a new fragment if savedInstanceState is null.

Android click on view above the view

I have tab Layout with dynamically added custom tabs (Image View + Text View)
I want to change image on select tab and on reselect (2 kind of images)
But there is no click event listeners on Tab, so I added transparent layout to catch clicks.
How do I need to change settings, to make 4 Linear Layouts clickable?

the following answer deals with somewhat the same question and the answer marked as solution is what you're looking for, it explains how to define and use selectors

Well, you can change image on a selected tab by two method which you need to create in Custom Pager Adapter and call it from tab selected listener.

tabLayout = (TabLayout) findViewById(R.id.tabs);
createViewPager(viewPager);

createTabIcons();
adapter.SetOnSelectView(tabLayout,0);
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {

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.

Adapting a layout using a Dialog Fragment

I'm trying to adapt a layout in a dialog fragment to show an imageview, a text view and two butttons, but I have problem adapting the layout in it.
I get this:
http://kitsord.com/imagestack/Screenshot_2014-05-22-11-35-22.png
And the output should look something like this:
http://kitsord.com/imagestack/looks.png
So I don't know why the text and the buttons don't show correctly.
The DialogFragment is this one:
public class LearnFragment extends DialogFragment {
ImageView imgC;
VideoView myVideoView;
View root ;
TextView textv ;
ImageButton next , atras;
Integer contador;
public static LearnFragment newInstance() {
LearnFragment f = new LearnFragment();
return f;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
contador = GridViewFragmet.positionarchivo; // this is a static variable from another class
if (getDialog() != null) {
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawableResource(android.R.color.transparent);
}
LayoutInflater inflaterr = getActivity().getLayoutInflater();
root = inflaterr.inflate(R.layout.aprender_fragment_display, null);
myVideoView = (VideoView)root.findViewById(R.id.videos_aprender);
imgC =(ImageView) root.findViewById(R.id.imagenes_aprender);
textv = (TextView) root.findViewById(R.id.text_aprender);
next = (ImageButton) root.findViewById(R.id.btnnext_aprender);

I found my problem. The problem was at my class of Dialog Fragment.
The line that was giving me the error was this one:
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
That was what affected the whole dialog and moved the layout.
