ViewPager not responding to touch in layout area created dynamically in Fragment

I'm trying to implement Viewpager with a calendar. I'm using the same three instances of the calendar Fragment for testing the ViewPager lets call the smooth motion of transferring one fragment to the next SWIPING. the swiping will not work in the area of the fragment that the layout was created dynamically in the fragment itself but the rest of page(above and below the date buttons)the swiping works great! here is some of the code the entire frag code would not fit so had to edit some declarations and button listener methods
// Main Activity
public class calenderview extends AppCompatActivity {
ArrayList<Fragment> fraglist;
ViewPager pager;
calenderviewpageradaptor adaptor;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calenderview);
fraglist = new ArrayList<>();
fraglist.add(new Calview_frag()); fraglist.add(new Calview_frag()); fraglist.add(new Calview_frag());
adaptor = new calenderviewpageradaptor(getSupportFragmentManager(),fraglist);
pager = (ViewPager)findViewById(R.id.pager);
pager.setAdapter(adaptor);
}
public class calenderviewpageradaptor extends FragmentStatePagerAdapter {
ArrayList<Fragment> adaptorlist;
public calenderviewpageradaptor(FragmentManager fm,ArrayList<Fragment> list){
super (fm);
this.adaptorlist = list;
}
#Override
public int getCount(){
return 3;
}
#Override
public Fragment getItem(int pos){
return adaptorlist.get(pos);
}
}
}
public class Calview_frag extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

are you passing the instance of the Fragment to the adapter? No I think. You should pass the list of fragments to the adapter along with fragment manager and should also change the calendarViewPager accordingly.
List<Fragment> fragments =new ArrayList<>();
fragments.add(Calview_frag());
fragments.add(Calview_frag());
fragments.add(Calview_frag());
calenderviewpageradaptor adaptor =
new calenderviewpageradaptor(getSupportFragmentManager(),fragments);

First image appearing small in size and on top left corner in a viewpager when rotate the device

Hi in my application i am using the Viewpager with PagerAdapter. it contains n number of images. but when i rotate the device when viewpager is on first image then the image shift to top left corner and appears very small. please have a look in the attached image.

Try Changing
**<View
android:id="#+id/overlay"
android:layout_width="260dp"
android:layout_height="20dp"
android:layout_below="#+id/lbl_balance" />**
to
**<View
android:id="#+id/overlay"
android:layout_width="260dp"
android:layout_height="20dp"
android:layout_alignBottom="#+id/heart_ImageView" />**
Changes made: layout alignment and the id of to whom it was aligned

You can try adding rules to the params with the addRule method
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
I'm not near my PC to test, but you may be able to set the view below lbl_balance with the addRule method
Or, try removing the layout params in the code all together. The xml inflates the view, so it is already created. All you need to do in code is set the background color. Which you can also do in the xml with
android:background="#80000000"

Delay in for loop-android

I'm new to android programming and I have a simple question. I have a random number, nr and I generate this number of ImageViews in the same location. Now, I want to apply an animation to each of these images, but not in the same time.
Let's say I want the first image to start moving at sec 0, then image2 at sec 2 and so on.
I have the images in an array, imb_items[].
for(int j=0; j<nr;j++){
imb_items[j].startAnimation(translateAnim);
????? how can I put here the delay?
}
I'm trying for a long time to do this, but I just can't do it with handlers or threads...I think I don't get the concept.
I would be very thankful if somebody would help me understand and give me a sample code that will work in my specific case.
thank you!

Try this:
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
// YOUR CODE HERE
}
}, 2000);
Where 2000 is 2 seconds delay/sleep in main thread.

You can use thread concept and in loop you can use sleep function for delay and you can write your code in it
thread = new Thread() {
public void run() {
while (true) {
try {
YOUR FOR LOOP CODE HERE with this line "Thread.sleep(2000);"
} catch (InterruptedException e) {
Log.e(TAG, "local Thread error", e);
}
}
}
};
thread.start();

For create delay, you can use this code:
try {
Thread.sleep(m); // m is millisecond, if m = 1000 ms then delay = 1 s
}
catch (InterruptedException e) {
e.printStackTrace();
}

If I use this
for(int j=0; j<i;j++) {
final int finalJ = j;
new android.os.Handler().postDelayed(
new Runnable() {
public void run() {
imb_items[finalJ].startAnimation(translateAnim);
Log.i("tag", "This'll run 5000 milliseconds later");
}
},
5000 * j
);
}
the problem is that when when the second image starts moving, the first one stops and disappears. I would like all the images to continue their movement.

This is the final solution:
for(int j=0; j<i;j++) {
translateAnim[j].setStartOffset(5000*j);
imb_items[j].startAnimation(translateAnim[j]);
}

I Have made it as a widget and Now finally to add this to your List View use
frame = (QuickReturnRelativeLayoutFooter) newProjectsView
.findViewById(R.id.frame);
frame.attach(projectsList);
where projectList is your List View
example
ListView projectList =(ListView)findViewById(R.id.projectList);
and Voila Cheers Completed Smooth as Heaven .......
