Whenever a button is clicked, I want all the listview items to inflate just like a menuInflater inflates menu items. Upon clicking an item in the inflated listview, I want the button's color to change.
The problem here is that the listview is dynamic, its contents depend on user input and I can't seem to find a way to inflate a dynamic listview.

I have a ListView in my layout. I have attached onItemClickListener for ListView to listen for item clicks. Whenever I will click on the item of it, a BottomSheetDialog will inflate. The problem is, that I want the content outside bottomsheetdialog to be clickable and scrollable. Whenever I inflate BottomSheetDialog, the content outside it becomes unresponsive. It doesn't respond to clicks, scroll etc. How can I make the content outside it to still be clickable and scrollable?
Hey I'm working on a custom view and I need to retrieve menu items from menu resources (e.g. menu.xml from res/menu) but I didn't found any way to do that. How can I get users menu items from resources?
I need to be able to clear the action bar menu and inflate a new one from within a nested fragment when the particular nested fragment becomes visible.
My app consists of a main activity with a ViewPager which uses a FragmentPagerAdapter. This ViewPager has 4 root fragments which are simply blank FrameLayouts (one in each page) that each contain and swap out nested fragments. These nested fragments can be different or the same type (think about how Instagram can show a different profile view in multiple tabs). This means that I can't use the onPrepareOptionsMenu to inflate menus on page swipe, because I won't know which nested fragment is in the root fragment of each page. Additionally, I have set the offScreenPageLimit to 3, so that I can swipe between root fragments without reloading. This means that I can't just inflate the menu from within the nested fragments, because then all four nested nested fragment's menus will appear.
The ideal solution would be able to inflate menus from within the nested fragments through some sort of callback that gets executed when the nested fragment is literally displayed on the screen, e.g. when we swipe to the page containing the root fragment which contains the nested fragment, or we swap the nested fragment for another within the root fragment of a page. Does anyone have a design solution to the problem I'm having? Thanks for any help!

Create a menu for the fragment in the menu directory
Report that this fragment has options menu have a look
Then just inflate it here, and override this method and when the fragment will become visible those menu options from fragment menu will be added to activity menu options.
I have Listview. And I want to add overflow menu to each listview's item. How to do it? Now I add button to every item and show dropdown menu when user clicks on this button. But I want to replace this ordinary button with overflow one.
Add an ImageView or Button to trigger the menu on the right of your listview items. To get the "overflow" icon, see this question: How do I get a copy of the Android overflow menu icon?
Add an onClickListener to your ImageView or Button
On your onCreate() method, create a popup menu like this:
popupMenu = new PopupMenu(this, findViewById(R.id.anchor));
popupMenu.getMenu().add(...);
popupMenu.setOnMenuItemClickListener(this);
In your onClickListener trigger the display of the popup menu
popupMenu.show();
In my app, I have a view pager with two tabs and I have two layouts and I want to inflate and show layout1.xml inside the tab when the user switches to tab #1 and inflate and show layout2.xml inside the tab when user switches to tab #2, but I cannot find how to do it.
Any help will be very much appriciated.
Create two fragments
Inflate one of the layouts in each fragments onCreateView() and return the view.
Return an instance of fragment 1 for the position 0 in your FragmentPagerAdapters getItem() method and an instance of fragment 2 for position 1.
