TabCustom | 仿微信底部菜单栏今日头条顶部导航栏

I am trying to create a simple function to sort an array with usort and I don't understand what's wrong with my code.

For the test, I want to order by the field 'str' in "descending" order.

My array for the test :

Explaining, I use the viewpager class for 2 activities. When you click on an item in the ActivityMainTab list, it is taken to another activity (ActivityAtTab), it also uses the same viewpager class as the previous one to generate its tabs and fragments.

I need to know if the Conduit fragment is what is on the screen, so that under the conditions I will show below, I can go to the correct method and continue the flow.

Below the codes:

ActivityAtTab, this method checks which fragment is on the screen, so that the matches variable goes to the correct showResults. In the case of mFragmentConduit, I can not tell if it is on the screen because it comes from viewPager. ActivityAtTab

• I am making my app with Tab in actionbar using Fragment. My code below:

  • Tab1Fragment.java & Tab2Fragment is the same

I can't for the life of me figure out why the ListView or TableView aren't outputting the bound data. Here's the view data that I'm trying to bind to both ListView and TableView

I have created a component in angular js which shows some data But on change of my customer binding i want to call some service in component controller which is not reflecting,Here is the below code

In my Test1.html

I have a viewpager which has five tab and control the tab with tablayout. the problem that i have is that the title doesn't change when want to go from one activity to another activity. the thing that i do is that i changed the textview title in tablayout in onTabSelected in the activity but in both on select tab and in on reselect tab method but sometimes it doesn't change anymore. another thing that makes the point is the map which i use the address of the map in my main activity title. i changed the address using setOnCameraChangeListener method and the problem with this case is that it run several time even when i am in another fragment and because i used it's address in my main activity title it change it.

at he also changed the title in both onViewCreate and onCreateView in each fragment but it doesn't work fine.

this is what everything that i did:
