How can I make angular material toolbar fixed top starting from very left corner of page and side nav below the toolbar. actually something similar to Angular material site (https://material.angular.io/components/categories), I could create it with bootstrap or with custom css but I want it pure Angular material any idea would be appreciated.

I want to animate the ALPHA property on an ImageView by means of an AnimatorSet (I actually have two animations, but I'm using the alpha one only for now in order to check if it works) I'm using Kotlin (and I'm new to it) I have a layout with the ImageView inside, an xml with the AnimatorSet and a Kotlin class related to the layout.

I have a search query done by me to the best of my knowledge in PHP but there are some improvements required:

1. When I search say 'what is food' and I have 'what is food' in the database all results containing one of the keywords 'what', 'is', 'food' are shown. The desired behaviour is to display results containing the exact phrase 'what is food' (first)

2. Only the last word in the query is highlighted and I want to highlight all words

Desired behaviour: The right answer shows at the top, regardless of its position in the database.

My current code is like this:

I have MyTrips fragment which contains ViewPager. So it contains two tabs i.e two fragments one is ScheduleListFrgment and another is TripHistoryFragment.

Now As I replace MyTrips fragment it first shows ScheduleListFragment, loads data from server and shows in a list, it also loads data of tripHistory from server.

So now I have given click event to the list item of ScheduleListFragment so onClick it replaces ScheduleListFragment with PostDetailsFragment.

Now after I press back from PostDetailsFragment it shows empty ScheduleListFragment with no list.

I want to show the list when user press from from PostDetailsFragment.

ScheduleListFragment

I have a home activity in that I am replacing fragments as required.

In home activity I have main fragment, then from main fragment I am replacing a Transport fragment, from Transport fragment I am replacing TransportList Fragment.

Now as I press back from TransportList fragment I see the main fragment instead of Transport fragment.

I have added the fragments to backstack still its working like this.

Home activity

I have an activity which has a toolbar, in that toolbar I have added one image view and have set the logo in it.

Also I have created different fragments, now when I see the fragment I want to hide that image view and set the title to the toolbar of an activity.

I have set the image view and toolbar as public static in home activity.

I tried to access toolbar like this:

I am collecting GPS location data in Splash Screen and store it in session, and use it later in MainActivity. If the GPS is turn off or used for the first time it will ask for permission in my splash screen. The problem is that I am using the timer to move splash screen Activity to another activity. Due to the timer, SplashScreen is moving to next the activity without the permission. I want my Splash screen to wait till permission dialog is allowed or denied. Below is my code
