Fairly inexperienced in java still, so I was wondering (as I haven't really found anything useful online) whether there was a way to permanently delete a textview (or any other layout entry, ratingbar etc.) from an android layout in the onclick function.
I want a user to be able to submit a rating only once in every rateable activity, you see.
I have tried everything I can get.
ratingbar.setVisibility(View.GONE);
Works while you're in the activity, yet when you restart again the ratingbar is back. I've also tried:
linearlayout1.removeView( ratingbar );
However, this does the same as
ratingbar.setVisibility(View.GONE);
On reload the ratingbar is back. If anyone can help, that'd be greatly appreciated.
Thanks in advance.
Well you rather choose not to create a view,
than deleting a view that's created.
i guess you could create TextView programmatically
and decide if you want to attach it to your layout or not in java code.

I am building an E-Commerce App and I have an activity showing image slider, description and related items, and in image slider I have put an arrow to change the product on the arrow click I want to be in the same activity but data should be different.How should I do that need your help guys.
You should try doing it by urself in one of the many ways its possible to. Then we could provide some help with your idea or show you better solution. I think you are looking for RecyclerView (https://developer.android.com/guide/topics/ui/layout/recyclerview). It lets you show some similar views but with different data inside. Also as an item inside RecyclerView you can try CardView.
Using only RecyclerView you can also use:

You can also search for a library that has everything you want inside already implemented. For example the first library that came out after i typed it in google : https://github.com/Ramotion/cardslider-android.
I am trying to build an app using the new material design specs.
I am currently trying to get a cusdtom FAB layout working, similar to the one in the new Inbox app.
I have one main button, which when clicked, expands to several smaller ones.
However i want to add a textview to the left of the smaller buttons, like the inbox app.
I cant seem to find a way of doing this.
The floating action button i am using is based off this library, but with a few modifications https://github.com/futuresimple/android-floating-action-button/blob/master/README.md
If someone could suggest a way of doing this, it would be much appreciated.
Thanks

I need some help.
I'm wanting to make an activity similar to this, but I'm not sure where to start.
Basically, it's like a texting UI, with the users question on the right and the answer on the left. I was going to use a list view for the sake of simplicity, but I dont' think it'd support this kind of structure.
I googled some layouts where I can scroll, but most of them require me to premake them, which isnt an option because its a dynamic chat log.
Does anyone here have experience with this kind of UI? Can you point me in any direction? I hate to ask such a strange question, but I don't even know how I'd word this situation on Google.
Thanks in advance.
What you're looking for is a ListView where you can return a different layout depending on whether the message is sent or received. A ListView is the most efficient implementation for this because its ideal for displaying a potentially large data set without having to keep a view in memory for every row.
This is achieved by extending the BaseAdapter in your application and overriding the getItemViewType(), getViewTypeCount(), and getView() methods (along with all the other methods required by a ListView adapter).
This is a good tutorial that serves as a walkthrough for this pattern.
Instead of using ListView, You may programmatically construct a viertical LinearLayout, and add TextView in each line, you can set the alignment of the TextView in lines accordingly.
I have an app that uses this RibbonMenu and I wanted to know if it was possible to use the menu items to change the ContentView of the Activity instead of another activity to reduce the size of my app. I've tried doing this already,and it changed the content view perfectly, but i was not able to press the home button. I'm in a bit of a rush here, but i'll try to post code if anyone asks for it. thank you!
Menu items is UI element. It does nothing by itself. It however can trigger some more actions in your code. As for changing activity layout, yes, you can call setContentView() at any time you want.
to reduce the size of my app
this is not the way optimalizations should be done
I'm a noob Android developer. I learned of the basic UI controls and different types of views that I can utilize.
Now my problem is, I need to show list of items using the ListView that is being shown full screen. when I click on an item it should load a TextView full screen. when I click the back button it should go back to ListView again..
Can someone point me where I can learn such stuff?? any support or even external link is greatly appreciated.
Thanks in advance.
Write your text view in a different activity. And when ever you click on a list item start that activity putting your text in the intent. Fetch the text in that text view activity in onCreate() from the intent and set it to text view. Obviously when ever you click back you 'll come back to list view activity.

He's no longer updating but what you've asked is covered in the video tutorials he did create. It's not answered directly but by watching them, you should have a solid enough understanding to piece it together yourself.
Best of luck!
