I want to automatically reload function after setOnClickListener.. here is my code below

Here is my code below:
tvWatch.setOnClickListener(v -> {
earnCreditDialog.dismiss();
RewardedAd rewardedAd = adMobUtils().getRewardedAd();
if (rewardedAd != null /*&& rewardedAd.isLoaded()*/) {
isEarnCredit = true;
rewardedAd.show(TournamentActivity.this, rewardedAdCallback);
rewardedAd.setFullScreenContentCallback(setFullScreenContentCallback);
} else {
CommonUtils.showMessage(TournamentActivity.this, getString(R.string.earn_credit_not_available));
if (rewardedAd == null) {
Timber.e("Create New Rewarded Ad");
loadRewardVideoAd(true);
} else {
Timber.e("Loading Current Rewarded Ad");
}
}
});
I would also like to add a dialog that I have coded already before the rewarded ad is shown. Here is the code below:
public void showAdsLoadingProgressDialog() {
if (adsLoadingDialog == null || !adsLoadingDialog.isShowing()) {
adsLoadingDialog = new Dialog(BaseActivity.this);
Window window = adsLoadingDialog.getWindow();
if (window != null) {
window.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
}
adsLoadingDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
adsLoadingDialog.setContentView(R.layout.custom_ads_loading_dialog_layout);
adsLoadingDialog.show();
adsLoadingDialog.setCancelable(false);
adsLoadingDialog.setCanceledOnTouchOutside(false);
}
}

Display list user with gridview android studio

I'm having trouble removing the "parent channel shortcut" even though I already have it hidden (view2.setvisiblity(view.GONE)). I'm using gridview android:numColumns="3".The list user display starts from the left side, If I want to remove it, how do I do that?

ArrayList won't Add more than one Item

My Array will not add anything to the list after the first and keeps returning null when i search for anything after.
Is there something wrong with this method?
public void addItem(Item newItem) throws DuplicateItemException {
Item tempItem;
if(itemList == null)
itemList.add(newItem);
try {
tempItem = findItem(newItem.ID);
if(tempItem == null) {
itemList.add(newItem);
}
else {
throw new DuplicateItemException(newItem.ID + "already exists");
}
}
catch (ItemNotFoundException e) {
itemList.add(newItem);
}
}

In your code:
if(itemList == null)
itemList.add(newItem);
if itemList is indeed null, how can you add to it?
Use this instead
if(itemList == null) {
itemList = new ArrayList<>();
itemList.add(newItem);
}

AccessAbiltyService not working when screen turn off android

I develop a android app here hava a accessabilty service for read window text from ussd dial.
I am success for do it and it working nice. But when screen light turn off and get locked The accessAbiltyService not working.

Buttons not working at first and last index?

I am working on an application in which have two navigation button namely 'previous and next' which on tap load stories respectively. When i tap these buttons gently they work fine button when i tap next button to the last index continuously without any break then the previous button does not work or similarly when i start tapping previous button to the very first index i am unable to move forward.
Remember this only happens at the extreme cases, onClick is not called, don't know why.
My code is as follows, please help me out. Thanks in advance.
this the code of onClick, which works fine in all cases except the extreme cases, when buttons are not tapped gently.
public void onClick(View v) {
if (visible == true) {
Log.e("visible", "true");
return;
}
visible = true;
try {
Log.e("Now", "On Click");
pDialog = new ProgressDialog(StoriesListController.this);
pDialog.setIndeterminate(true);
pDialog.setIcon(R.drawable.icon_small);
pDialog.setCancelable(true);
if (isFavoriteList == true) {
pDialog.setMessage("Loading favorites...");
} else {
pDialog.setMessage("Loading data...");
}
pDialog.setTitle("Please wait");
pDialog.setOnCancelListener(new OnCancelListener() {
public void onCancel(DialogInterface arg0) {
if (cancelableHeavyWorker != null) {
cancelableHeavyWorker.setHandler(null);
}
finish();
}
});
pDialog.show();
if (v == next) {
if (ind < items.size() - 1) {
ind++;
loadAndShowNextActivity();
}
} else if (v == previous) {
if (ind > 0) {
ind--;
loadAndShowNextActivity();
}
}
// realeaseMemoryIfneededofStory(ind);
} catch (Exception e) {
Log.e("Error", "--.OnClink Message" + e.toString());
e.printStackTrace();
}
}
Moreover, the boolean variable "visible" is being set to false in the callback function.
The Code of Call Back Function is as follows:
private void fetchTopStoryDetailCallback(Object resultVector) {
System.out.println("fetchTopStoryDetailCallback");
try {
Vector<?> v = (Vector<?>) resultVector;
boolean completedOrFailed = ((Boolean) v.elementAt(0)).booleanValue();
if (completedOrFailed == true) {
boolean slideshow = ((Boolean) v.elementAt(1)).booleanValue();
Object result = v.elementAt(2);
String res[] = (String[]) result;
if (slideshow) {
if (Utils.topStorySlidesArrayList != null && Utils.topStorySlidesArrayList.size() > 0) {
Intent articleActivityIntent = new Intent(this, SlideShowActivity.class);
articleActivityIntent.putExtra("storyData", (String[]) result);
articleActivityIntent.putExtra("back", back);
articleActivityIntent.putStringArrayListExtra("sid", slideids);
// articleActivityIntent.putExtra("contentType", )
articleActivityIntent.putExtra("addkey", ADDS_KEY);
showActivityInContoller(articleActivityIntent);
hidePrgressgingDailog();
} else {
hidePrgressgingDailog();
this.closeActivity = true;
showMessage("Error", "This story encounter an error while opening. Check your Internet Connection and try later");
}
} else {
if (res[3] != null && (!(res[3].equalsIgnoreCase("null")) && (!res[3].equals("")))) {
Intent slideshowActivtyIntent = new Intent(this, ArticleActivity.class);
slideshowActivtyIntent.putExtra("storyData", (String[]) result);
slideshowActivtyIntent.putExtra("back", back);
slideshowActivtyIntent.putExtra("addkey", ADDS_KEY);
showActivityInContoller(slideshowActivtyIntent);
hidePrgressgingDailog();
} else {
hidePrgressgingDailog();
this.closeActivity = true;
showMessage("Error", "This story encounter an error while opening. Check your Internet Connection and try later");
}
}
} else {
showMessage("Error", "This story encounter an error while opening. Check your Internet Connection and try later");
hidePrgressgingDailog();
}
} catch (Exception e) {
Log.e("StoriesController", "Message = " + e.toString());
e.printStackTrace();
}
finally {visible = false; }
}
this is how visiblity of the buttons is set...!!!!
private void adjustButtonsVisibility() {
try {
if (items.size() == 1) {
next.setEnabled(false);
next.setImageResource(R.drawable.navigator_next_disable);
previous.setEnabled(false);
previous.setImageResource(R.drawable.navigator_previous_disable);
//hidePrgressgingDailog();
return;
}
if (ind == 0) {
previous.setEnabled(false);
next.setEnabled(true);
previous.setImageResource(R.drawable.navigator_previous_disable);
next.setImageResource(R.drawable.story_next_arrow);
hidePrgressgingDailog();
} else if (ind > 0 && ind < items.size() - 1) {
previous.setEnabled(true);
next.setEnabled(true);
previous.setImageResource(R.drawable.story_previous_arrow);
next.setImageResource(R.drawable.story_next_arrow);
}
if (ind == items.size() - 1) {
previous.setEnabled(true);
next.setEnabled(false);
previous.setImageResource(R.drawable.story_previous_arrow);
next.setImageResource(R.drawable.navigator_next_disable);
hidePrgressgingDailog();
}
} catch (Exception e) {
Log.e("Error", "--,adjustButtonsVisibility Message = " + e);
e.printStackTrace();
}
}

Do this
if (ind == 0) {
previous.setEnabled(false);
previous.setImageResource(R.drawable.navigator_previous_disable);
next.setImageResource(R.drawable.story_next_arrow);
hidePrgressgingDailog();
}
else if (ind > 0 && ind < items.size() - 1) {
previous.setEnabled(true);
next.setEnabled(true);
previous.setImageResource(R.drawable.story_previous_arrow);
next.setImageResource(R.drawable.story_next_arrow);
}
else if (ind == items.size() - 1) {
previous.setEnabled(true);
next.setEnabled(false);
previous.setImageResource(R.drawable.story_previous_arrow);
next.setImageResource(R.drawable.navigator_next_disable);
hidePrgressgingDailog();
}
