How can I hide everything behind the ProgressDialog and only show them only after getting completely loaded? Actually I need a white screen behind the dialog above my WebView content while the progress is running.
Give the layout you want to hide an ID in the xml files, then find that layout in your activity/fragment, and then you can use '.setVisibility(View.GONE);" to hide it as you want, or '.setVisibility(View.VISIBLE);" to show it.
Then simply hide it by default, and when you got your data, show it.

I'm new to android. Ok so what I want to do is dim everything except the lottieAnimationView whenever I make the lottieAnimationView visible and also make everything back to normal when I turn lottieAnimationView gone. I tried a piece of code but it doesn't work
Edit: Maybe its possible through making the lottieanimationview visible inside an alert dialog box so can someone provide the code for that.
You need to create Custom Dialog which contains LottieAnimationView through which you can achieve desire output.
You can get an idea that how to create Custom Dialog using below link.

I want to create a tabbed activity or empty activity in Android Studio, but I need to be able to swipe to a page 2.
All I would like is for the app to say the standard "Hello World" on the 1st screen, and then you can swipe to the next page that says "Hello World Page 2", Just those 2 screens with no title bar on any of the screens - that's it.
I've tried creating a tabbed activity and was able to create both pages and swipe works, but it creates a button in the lower right corner and a title bar with settings button up top that I couldn't figure out how to delete.
I tried an empty activity but couldn't figure out how to add another page. If anyone could provide me the code or a sample project I could edit that would be amazing as I've lost several days in frustration over this.
You can use ViewPager component. When you will use it you would to use TabLayout, but if you want to hide it you just simply can edit its visibility.
You Can try this Example.

Simply replace the image with TextView.
To hide the actionbar user getSupportActionBar().hide()
I am trying to implement a simple logic in my application where the user is shown a popup (after sometime of application launch). The popup simply shows a TextView with some info message. This message is refreshed every time the application is launched and a new message is shown.
The UI of the popup matches my application UI - here maybe just popup background images is needed. Also one close button (X) is shown at the top right corner of the popup - to close this popup.
Logic of Showing Message: I have a String array having some 100 strings stored in it. I randomly pick one string from this array and populate the popup TextView showing the message. Please suggest if there is any better approach than what I am doing already here. Also is it possible to logic that if one message is picked then the same message is not picked until the other messages are shown at least once?
Logic of Showing Popup: This is what I am not able to implement. I do not want to anchor the popup with any user Event or Button click. I simply wants to show the message after some time - say
Thread.sleep(3000);
Now I have tried to use PopupWindow for this using the below code.
PopupWindow infoPopup;
LinearLayout infoLayout;
TextView infoTextView;
Button infoButton;
infoTextView = new TextView(this);
infoTextView.setText("Testing Popup Text");
infoTextView.setPadding(10,10,10,10);
infoButton = new Button(this);
infoButton.setText("Close");
infoLayout = new LinearLayout(this);
infoLayout.setOrientation(LinearLayout.VERTICAL);
infoLayout.addView(infoTextView);
infoLayout.addView(infoButton);
infoPopup = new PopupWindow(infoLayout,LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT);
infoPopup.setContentView(infoLayout);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
infoPopup.showAtLocation((CoordinatorLayout)findViewById(R.id.main_content),Gravity.CENTER,100,100);
But this popup is showing error at the last line giving null pointer on my
(CoordinatorLayout)findViewById(R.id.main_content)
parameter.
The issue that I am getting are:
First of all, I am not sure if this is the right approach of showing a custom UI popup. I am aware of AlertDialog but not sure which is the best option to go in this case - Please suggest.
Why the CoordinatorLayout is showing null pointer?
How to implement the top right (X) button logic in this Popup ?
1. Yes there are so many options for showing a custom UI popup in Android. You might select one from PopupWindow, AlertDialog or Dialog Activity. You need to decide which suits you best.
If you need to customize your UI a lot and have to show a list or some complex GUI then I would suggest you launch an Activity with theme.Dialog. Just set the theme of the Activity to something like this android:theme="#android:style/Theme.Holo.Light.Dialog". There's a plenty of tutorials for implementing a dialog Activity.
PopupWindow is another tool to customize your custom pop up anywhere in the screen. If you're showing this popup always in the middle of the screen, then I would like to suggest not to use this. The AlertDialog should work fine.
AlertDialog has many variants and as far as I can assume your problem, this one suits you best. You can have a cross button too in the top-right corner of the dialog (You can set the icons anywhere, as you can provide a custom layout to an AlertDialog). Personally I use this library to provide a custom layout to my AlertDialog. You can have a look at this too.
2. The NullPointerException is simple. Your layout doesn't have any id named main_content. Post your logcat if this doesn't solve your problem. Post the layout too.
3. As I've told you earlier, I use the library to provide a custom layout to an AlertDialog and you can have a look at it too. So after implementing this library you can easily design your own layout with a cross button and implement the onClick functionalities easily.
Hope this helps.
Activity with theme Dialog.
This is not a good idea. It looks like a pop-up, but you can't click outside the pop-up to close it.
PopupWindow
It will stop the application. When the user finish clicking the pop-up, the application can work again.
AlertDialog
The best one, it will not stop the application and can be closed by clicking outside the dialog.

Achieving a true "dropdown" effect (as seen in Adobe's Photoshop Mobile app for Android, image below) has proven challenging using Androids built-in methods.
As others on Stackoverflow have told me, editing the style of a dropdown list view of an Android spinner is limiting.
How is this dropdown effect done?
(I can't seem to get an image to show, so here's a link: Adobe Photoshop Mobile for Android
After viewing the Adobe slideshow I think the way I would attempt to get that to work, using the Android Java SDK, would be to create a ListView object with a transparent background, and then dynamically hide/show it in that position when the menu button is clicked by setting the View's visibility to VISIBLE or GONE.
Getting a ListView to be transparent shouldn't be that difficult. I'd look into AbsoluteLayout to get it to hover over everything in that spot.
Another option might be to display the ListView in a custom Dialog that you've written, again positioning it in that exact spot on the screen so that it looks like a menu extending from the button that was clicked.
It's probably done using low-level draw functions.
