I'm using the following tutorial http://developer.android.com/resources/tutorials/views/hello-mapview.html in order to create a map view and plot points on to it. I have all of that done fine but now I'd like to embed an image and even audio within the Alert dialogs that pop up. Is this possible in the current context? How would I do it?
You need to create a Custom Dialog.

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.

Dialog with transparent background in Android
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.
I have an android dialog
I saw this tutorial for swiping a dialog in and out.
how can I filp a dialog when the user clicks on the dialog.
I want to actually show the user two dialog with different content and trasit with flip between them
Try using the code from google or combine it's xml if it works, saw also good example here
good day sirs. I've been struggling with this dialog because it keeps on saying I should have a table skin for my table but I'm not even using a table. However I have a skin ".atlas" file which contains packed images for my graphical user interface such as windows buttons.
Is there any way I could resolve this problem?aside from ".json" is there anyway?
My modal dialog worked using another stage. When I wanted to show it, I changed the InputProcessor to my dialogs internal stage so other GUI objects couldn't respond to user input outside the dialog.
I found LIBGDX's dialogs overkill for my purposes. Perhaps you need a skin for your dialog? If not I'd just go with my approach. You could always use a texture atlas instead. It can function much like a skin as strings are used to reference regions of an image.
I hope I can explain this properly.
I'm making an android app that, when you open it, it connects to a JSON server, pulls down the data (GPS coords) and dynamically creates a "menu" based on what it received (View1). This will consist of a few buttons, which when clicked, will load a MapView (View2) with the coords gotten from the JSON represented as markers on the map.
I start off with setContentView(R.layout.menu) then get the data, onbuttonClick I load setContentView(R.layout.map) and draw the markers. The problem is, I have an onLocationChangedListener that goes through the code to set up the menu initially. When it tries to build the menu when the mapView is open, I get a force close. Unfortunately, this code also updates the user location and the locations of the overlays and re-draws the map.
My question is: Can I do a check on a layout to say something like if (isActive) so that I can perform actions only if the current view is in focus?
OR should I scrap the whole thing and start again with a better layout? (Suggestions welcome)
Summary::: I have 2 views (menu,map). Need access to same data across both. Currently works with setContentView() but gives me a Force Close when actions are performed on inactive view.
If I understand correctly, you are using setContentView(someLayoutId) to change each time what the Activity is displaying. This is not the way android apps usually work. When you retrieve a resource, you need a root element to reference it, that's why you get the exceptions when the View is not "active".
You have several other options to evaluate:
Create a new MapActivity to show the map
Create a TabActivity and add the map as a new tab
Use a ViewSwitcher to decide whether to show the map or not.
