I am new to writing Android apps, I have been using the internet and Android Studio to create an app for my club as a bit of fun and learn along the way. I have been watching videos, using tutorials and walkthroughs and I am getting to learn the basics.
However, I have got stuck. I used a drawer template from Android Studio and added the activities I needed and buttons on the main screen to the activities and they all worked fine, no overlapping. When I tried to link the drawer icons to the activities, rather than use the buttons on the main screen, they work, but the app (visually) puts the next activities content on top of the one before.
I cant find anything on the internet except something called backstacking, but that is described when the back arrow is used, my problem is to do with selecting an activity from the drawer menu. I have attached a picture to show what I mean. It gets worse the more menu items that are selected.
If anyone could help, it would be great!
If you are using XML root layout as a constraint layout maybe your constraints are missing. If you are using constraint layout set both top/bottom and left/right constraint.
If your constraints only top for example it is look good on desing but in device that dont know where to positioning left or right and automatically positioning 0 point to top.
When you click one any one menu item put the visibility of other images as gone like
visibility(View.GONE);
and the one selected to be visible

The problem is that when i'm adding a Tab Layout inside another layout everything that appears in the blueprint becomes a dot in the upper left corner, leaving me with no other choice but to edit the xml itself in order to create the UI. This also happens sometimes when I add multiple nested layouts.
I'm searching like a week until now but still i can't understand why is this happening.
I've been using the SWReveal View Controller as the basis for my app in iOS, and I want to find an analog in Android. I'm hoping to keep the same drawer effect going left and right as appears in John LLuch's SWRevealViewController https://www.cocoacontrols.com/controls/swrevealviewcontroller.
I know you can use a navigation drawers controller to show the left, but that is a pop over. It's not like moving the center screen over to the right. I am also aware of there being the Fixed tabs controller, but those do not allow the center screen to be shown on top either. I am hoping somebody has mimicked a controller in android that allows you to move the three screens as if you were paging between them and still show your center screen at all times.
Please let me know if you guys know of one or know how to make the fixed tabs controller do this.
Google has a navigationDrawer that looks similar to the SWRevealController. However in all our projects we use https://github.com/adamrocker/simple-side-drawer/tree/master/SimpleSideDrawer as it seems easier to get used to it.
It is not exactly the same but you will get same results. We always make a Base Activity that all the menu activities extends in order to get the actions of the menu.
It is as having a FragmentActivity and on the onCreate method add these:
mNav = new SimpleSideDrawer(this);
mNav.setLeftBehindContentView(R.layout.menu_left);
mNav.setRightBehindContentView(R.layout.menu_right);
I hope that helps!
Hi I am developing an application that needs to display list of items. Clicking (or Tapping) on an item should display a description text of the item right below the item. I am talking about something like a vertical accordion.
I want them dynamically created (created in code rather than the XML). That part was completed with ease. I inflated multiple SlidingDrawer in a LinearLayout to accomplish it.
But the problem is only one SlidingDrawer is displayed in the activity. This was accomplished by giving fixed heights to SlidingDrawer. This approach will not hold as I mentioned above that the list of items is dynamically generated and also the area in the activity where the description of the item must come remains blank.
I am now looking for alternative views for accomplishing this. As I am a beginner in Android Development I cant find any that will work in android versions 2.3 and later.
You can always take a look at the SlidingMenu. The project can be found on GitHub. I guess you need to modify the behaviour a bit.
I am making an app that should implement a slider menu like the one in Spotify (where you slide the triangle in the middle to show the current playing song). The problem is I can't seem to figure out a decent method of doing this. I tried it with a Facebook like menu I found here.
However that just provides me with 2 linear layouts which are placed next to each other and are basically stretched or unstretched when expanding the menu. This gives some layout issues when expanding/collapsing (all items are placed below each other in the linearlayout when expanding and are quietly moved into the right place when collapsing the menu again).
In Spotify on the other hand it seems as if the layouts are on top of each other when the menu is expanded. This seems like a much cleaner way. However I have no idea on how to tackle this and Google doesn't really provide a lot of answers. Physically sliding the menu up isn't necessary, just getting the layouts on top of each other with some sliding animation on clicking the menu button.
Sorry for the long post, it seemed necessary to specify the question.
You dont need to re-invent a view or do anything fancy to get this functionality. Its called SlidingDrawer and is already available in the framework. Read this and this or watch this video.
I am looking to create a navigation or menu bar similar to the functionality of the one at the top of the Fox News app. I started to code this myself using a Gallery but I'm not sure how to hide the left and right arrows when they are not needed. I was also wandering if you would have to use images for the menu items or if you could just use TextView or buttons so I could change the text without having to modify an image. I have seen this type of navigation on several apps and I tried all types of searches trying to find code examples but I must not be using the correct name for this type of scrollable menu because I couldn't find anything. If anyone has an example or provide a link to an article I would greatly appreciate it.
Look into HorizontalScrollView. It is a Layout that will handle the smooth scrolling and is likely to be much less of a hassle to work with than Gallery for this operation (I just added one for a similar reason).
To handle the left/right, look into setOnTouchListener. I'm not sure if you can get the current scroll position without making a new child class of HorizontalScrollView to access protected methods. There may be other ways, however - I didn't need to add buttons so I didn't investigate.
