Can't change Android CalendarView to another month (Samsung S Duos - Android 4.2.2)

Android introduced a CalendarView back in in API 11. I've implemented it in my app and it seems to work fine in the sense that it displays a perfectly normal-looking whole-month calendar and I can select a date. It triggers the appropriate event and I can read the selected date in my code with no problem.
But I can't advance it out of the current month! The documentation says
A user can select a date by taping on it and can scroll and fling the
calendar to a desired date.
(the "taping" appears in the documentation; I assume it's a typo for "tapping" )
I've tried flinging, swiping, scrolling and nothing happens. Is there something I need to do to enable this feature?
My XML looks like this:
<?xml version="1.0" encoding="utf-8"?>

Edits:
Sorry for the long XML - in my original posting I just had the CalendarView but someone requested the entire XML.
Also to rule out the possibility that it might be unique to the device I've tested this on my Samsung S5 (Android 5.0) and got the same results.

as per my assumption, it's not scrolling or fling just because of a scrollable parent, can you check it without scroll view?
because I tested it with
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<CalendarView
android:id="#+id/debulkcalendar"
android:layout_width="match_parent"
android:layout_height="240dp"
android:minDate="01/01/2016"
android:maxDate="11/30/2016"/>
</LinearLayout>
and its work perfectly
you can use NestedScrollView
NestedScrollView is just like ScrollView, but it supports acting as
both a nested scrolling parent and child on both new and old versions
of Android. Nested scrolling is enabled by default.

#RBK was right, your parentView(ScrollView) interferes with its childView(CalendarView) which makes your CalendarView unscrollable. However, you can create your custom CalendarView which extends the base CalendarView class and override onInterceptTouchEvent method to get what you want.
Create your custom CalendarView class:
public class CalendarViewScrollable extends CalendarView {
public CalendarViewScrollable(Context context) {
super(context);
}
public CalendarViewScrollable(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CalendarViewScrollable(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
if (ev.getActionMasked() == MotionEvent.ACTION_DOWN) {
ViewParent p = getParent();
if (p != null)
p.requestDisallowInterceptTouchEvent(true);
}
return false;
}
}
Use it in your XML layout file:
<com.example.app.views.CalendarViewScrollable
android:id="#+id/debulkcalendar"
android:layout_width="match_parent"
android:layout_height="240dp"
android:minDate="01/01/2016"
android:maxDate="11/30/2016" />

How to make ImageView fullscreen programmatically on click?

Here is what I'm trying to do. I have 4 images and they are in one LinearLayout and that LinearLayout is child of RelativeLayout. I have successfully implemented onClickListener. Maybe my question is a little different, but everything is relevant.
I don't know how to extend image to full screen because images are in one LinearLayout which is inside that one RelativeLayout and maybe everything will be clear when I show you guys xml code.
I would like to make ImageView full screen on click and to be able to go back when I click back button. For that I would probably need to use onBackPressed
Images are at the bottom.
So here is the xml code:

And here is onClickListener:
image1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, 115, getResources().getDisplayMetrics());
int px1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, 150, getResources().getDisplayMetrics());
LinearLayout.LayoutParams p = new LinearLayout.
LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
p.weight = 1;
if(isImageFitToScreen) {
image1.setMinimumWidth(px);
image1.setMinimumHeight(px1);
image1.setAdjustViewBounds(true);
isImageFitToScreen=false;
}else{
image1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT));
image1.setScaleType(ImageView.ScaleType.FIT_XY);
isImageFitToScreen=true;
}
}
});

To offer an alternative to Ben's answer and flesh out my earlier comment, one possibility is to create an ImageView in your xml that occupies the entire screen, with its visibility set to gone. On your button press, load the image into this ImageView, and on a back press set the visibility to gone again.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ScrollView>
<!-- Everything else! -->
</ScrollView>
<ImageView
android:id="#+id/full_screen_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone" />
</RelativeLayout>
Inside your Activity's onCreate() method:
#Override
public void onCreate(Bundle mySavedInstances) {
ImageView fullScreenContainer = (ImageView) findViewById(R.id.full_screen_container);
image1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//However it is you load your images
fullScreenContainer.setImageDrawawble(R.drawable.example);
fullScreenContainer.setVisibility(View.VISIBLE);
}
});
}
#Override
public void onBackPressed() {
if (fullScreenContainer.getVisibility() == View.VISIBLE) {
fullScreenContainer.setImageDrawable(null);
fullScreenContainer.setVisibility(View.GONE);
} else {
super.onBackPressed();
}
}

Welcome to stack overflow Dusan,
I've something very similar, but all I do is just put the full screen image in a new activity & pass the image as bytes & display it in a full screened imageview. As soon as they press back, they're returned to where they were before. I think trying to change the layout parameters is a bit overkill here.

Create new Activity or Fragment and set image to ImageView in new Activity or Fragment. Using Fragment is better approach here as user can click on multiple images one after another. It is less expensive to create or destory Fragment.
Image can be passed to another activity by converting into byte array. It is better approach to save image on server or database such as firebase etc and use generated URL in app. Which make it easy to pass Url between Activities or Fragments than passing byte array

Android custom component width not matching parent

I have simple component - InfoPanel extending LinearLayout with 3 another linear layouts inside. Each of that 3 linear layouts contains 2 textviews.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:gravity="left|center_vertical" >
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"

android:gravity="left|center_vertical"/>
</LinearLayout>
<LinearLayout

android:layout_height="wrap_content"
android:layout_weight="0.5"
android:background="#android:color/transparent"
android:gravity="left|center_vertical" />
</LinearLayout>
</LinearLayout>
Java class for this component is pretty simple:
public class InfoPanel extends LinearLayout{
public InfoPanel(Context ctx)
{
super(ctx);
LayoutInflater.from(ctx).inflate(R.layout.info_panel, this);
}
public InfoPanel(Context ctx, AttributeSet attr)
{
super(ctx,attr);
LayoutInflater.from(ctx).inflate(R.layout.info_panel, this);
}
#Override
public void onFinishInflate()
{
super.onFinishInflate();
}
}
the main XML where i use that component seems like:
<TableRow
android:id="#+id/tableRow2"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<com.project.my.components.InfoPanel
android:id="#+id/InfoPanel"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</TableRow>
Problem is, that my component have width only something about 10% of width of screen. Right now i am trying to search some same problem (i found much of topics, but nothing worked for me) for more than 5hours..:/ I guess its something really small and stupid what i am missing. Thanks for all idea.

Thats good ,you find the solution of your problem,table row has default behaviour of using properties of first row in all rows.But deleting it solved your problem thats the key thing.

XML listview overlaps elements when setting visibility

I have an xml layout of about 3000 lines, which serves as the layout for a questionnaire type of app. Each page of the questionnaire is inside of a different linear layout and I set the visibility of the linear layouts in code using View.GONE or View.VISIBLE. This way the user can navigate through the pages without loading new intents each time.
However, when I navigate fast through the app (just pressing the next button to go through the screens), some of the elements that are supposed to be View.GONE shows up and overlaps over the VISIBLE items. This only happens with linear layouts that have list views inside of them. For all the other pages.
I can scroll fast through them, but just the ones with list views in the View.GONE elements sometimes shows up when I navigate too fast. How can I fix this ? Let me know if you want code ... however the xml is very large.
T.I.A.
EDIT
This is a sample of my xml code, I have 3000 lines of this repeating in my xml...

else

Toast.makeText(Screen_Package_Normal.this, "Authorized Signature Required", Toast.LENGTH_LONG).show();
}
}
});
I have different types of listviews and adapters, custom and android built in. I don't think the problem lies with the adapter since it works pretty well displaying the listviews and the problem occurs even before the listviews are populated...

I have a temporary fix, not sure how correct this is as an answer, but this fixed my problem... I applied this to my entire layout, and it adds an animation when I hide and show layouts, thus slowing them down a bit, removing the overlapping elements from showing up.
This is what I added to my layout:
android:animateLayoutChanges="true"

setContentView makes my ImageView buttons unclickable?

Having some trouble figuring out why my ImageView buttons stop working after I change the displayed layout in my app. Please tell me if you see anything wrong with this code... The buttons are not clickable after changing setContentView is called even though it is setting the layout to the same one that is originally set in OnCreate. Basically I want to be able to reset the view to an known state whenever I want by calling this function.
Thanks for any ideas! Here is the code that breaks the buttons, really only the line that calls setContentView breaks the buttons, but here is the rest of the function as well:
public void defaultrailview(){
setContentView(R.layout.railtrick);
ImageView jumpsbutton = (ImageView) findViewById(R.id.jumpsbutton);
ImageView settingsbutton = (ImageView) findViewById(R.id.settingsbutton);
jumpsbutton.setClickable(true);
settingsbutton.setClickable(true);
ImageView ghost1 = (ImageView)findViewById(R.id.rt1);
ghost1.setAlpha(51);
ImageView ghost2 = (ImageView)findViewById(R.id.rt2);
ghost2.setAlpha(51);
ImageView ghost3 = (ImageView)findViewById(R.id.rt3);
ghost3.setAlpha(51);
ImageView ghost4 = (ImageView)findViewById(R.id.rt4);
ghost4.setAlpha(51);
ImageView railtext = (ImageView)findViewById(R.id.railstext);
railtext.setAlpha(127);
ImageView shaketoroll = (ImageView)findViewById(R.id.ShakeToRoll);
shaketoroll.setVisibility(4);
}
and the XML for the railtrick:

Thanks again. Love you all!

When passing the same value into setContentView, you are still requesting for that resource to be inflated - meaning all new objects.
You need to reassign your onClickListeners because your old buttons are no longer on the screen.

you can try android:onclick="imageButton" in the xml and create a function in your class like
public void imageButton(View view){
// your code
}
