In the Google Maps application, when you open the menu and click on "Directions", it pops up a dialog that is unique to Google Maps. It keeps the MapView in the background, but displays the search dialog from the top (or bottom, if you're on an old version of Android).
I was curious if anyone knew how they achieved this effect. I'm willing to create a custom Dialog, but it seems that Dialogs are designed to pop into the middle of the screen (any other types of dialogs are denied permission as system dialogs). What trick is Google Maps using?
Just make your activity's root layout a FrameLayout or RelativeLayout (so your new view can overlap what's on screen). Then just add a layout with whatever you want as a child of that root layout (say, by inflating your desired dialog's XML into it when a button is clicked somewhere, either manually or using a ViewStub), and define a LayoutAnimation on the child before showing it.
For more on LayoutAnimations check out the API Demos app that ships with the Android SDK.

I know it should be in the style sheet area for this, but when I created a new Android app using Android Studio, it has a user logo and user information in a green box. This is what I want to edit.
First it should ask them to login if first time using the app.
But let's deal with one thing at a time, and first is me getting use to where Google puts things.
If you look at your layout activiy you will find a "NavigationView", there are 2 attributes there you need "header" and "menu".
You can see in this answer how.to get the views inside the "header" file: https://stackoverflow.com/a/33631797/4017501
There is another alternative. The "NavigationView" is a ViewGroup. So you can use it as such. Delete thee "header" and "menu" attribute and add the closing brackets as if were a ViewGroup:
<NavigationView></NavigationView>
Now you can simply put a fragment inside and then find every view and handle your logic from the fragment, is a more direct and customizable approach.
I want to make a drag and drop in my Android App.
This exemple (Link) needs a Long Click to start the Drag
But I want a Drag and Drop inside my App just like Facebook Messenger:
I also want that when the icon is clicked, a pop-up to be open
is there a way to use it inside an app?
I don't fully think this may solve everything but this might be worth a shot.
Try adding a frame layout as the parent(top level) layout of all of your activities' layout. Then add the chathead view on this frame layout which has the same child level as your activities' layout. This way you can still use the chathead while still interacting with your activity. #vinijow's answer is very helpful with this topic.
I'm developing an app that includes reviews of items and due to my design, I want to only show all the reviews in a popup window like in Google Play Store:
What should I use to create that white panel that appears over the current window and contains the necessary information? This should be simple but I'm a newbie and I can't seem to figure out what this "widget" is. Please help me if you are familiar with this so I can use this cool design pattern. Thanks.
It seems you want to display a layout as a popup in another activity.
If you want to do this using an Activity instead of a Dialog, you can do this by setting the activity's theme to android:theme="#android:style/Theme.Dialog" in the manifest - this will make the activity appear like a dialog (floating on top of whatever was underneath it).
A better way to do it would be using a DialogFragment. You can display information in the form of a popup and it will have its own lifecycle. That will be much better than displaying an activity like a dialog
Ram kiran's answer is a good one and one which I like to give also. But just so you have another option to look at you can consider PopupWindow
As stated in the docs, it is
A popup window that can be used to display an arbitrary view. The popup window is a floating container that appears on top of the current activity.
I've used this and it works out nicely in some situations. It really depends on what your exact needs are as to which will work best for you.
In the new Google Maps for Android API v2, I can very easily get custom markers and info windows to display. However, I'm trying to have multiple buttons inside of my info window, that each perform a different onClick action but the problem is, the map treats the InfoWindow as it's own button object (no matter where I click on the InfoWindow, it presses the entire thing). Does anyone know how to customize this a bit more?
Just found this in the documentation.
As mentioned in the previous section on info windows, an info window
is not a live View, rather the view is rendered as an image onto the
map. As a result, any listeners you set on the view are disregarded
and you cannot distinguish between click events on various parts of
the view. You are advised not to place interactive components — such
as buttons, checkboxes, or text inputs — within your custom info
window.
Unfortunately, that answers it. I was trying to add the same function as you.
I am not sure what the proper term is, but I am trying to add a "TitleBar" to the top of one of the windows in my App. Much like the Contacts App, I have several Tabs along the top of the screen. When you select an item from the list, it loads the next Activity, but that Activity no longer has the Tabs at the top of the screen.
I don't know if it is called a TitleBar or what. The Contacts App has this TitleBar along the top of the screen when you select a person from the list of Contacts.
I am trying to mimick the Grey Bar that says "George Washington"
The Contacts app is open source (as are most of the core Android system apps). I suggest checking it out and looking at the layout you want to emulate. In general, poking around a lot of that code is a good idea to get a handle on some best practices, or just to borrow a few tricks.
In this particular case, they're using a custom View called ContactHeaderWidget, which is actually a FrameLayout wrapping a TextView and Checkbox (styled to look like a star), along with the photo view (which has some special behavior to bind with the multiple contact source data on click and so on).
If you just want the look and not the functionality, though, just adding a LinearLayout with a GradientDrawable background containing an ImageView, a TextView, and a Checkbox styled as a star to your activity's layout should get you there a lot more easily without requiring custom widgets.
