SlidingTab | 可以交叉tab和文字的SlidingTab

I have a list that displays divs with class called delImg.

How can I get the count of instances of the same class before the one clicked?

Code I have tried is...

i have a activity with SlidingTab and when I click the back button of the cell phone the app just crash and show this error:

• I am using firebase, I don't know if this matters.

This is the Logcat error:

I have in my application two lists of messages, incoming and outgoing. These two lists are placed on the fragments, which in turn are in SlidingTab. And so it turns out that when you open a screen with these tabs, two requests from fragments are always sent to receive two lists of messages. But I need something to activate the fragment only when selecting the appropriate tab. Because when my access_token dies, I have two requests for a token update request, and one of the requests must return an error from the server.

logs of my error:

I'm trying to use the Elevation from Material Design to create Shadow on a Navigation Tab Bar.

Follow other guides I learn that I need:

• Put the padding on the parent view.
• Use ClipToPadding false on Parent.
• Declare the Elevation on the Child View.
• And Choose one Back Ground for Child.

I was able to do this in elements for my recycler view using adapters, but I'm not able to use this direct on my xml activity.

I am using Bottom Navigation View and in one of the options we display Firebase data, with a CardView.

But when I get out of this activity, and come back, either with the device back button or the activity arrow, it does not work. Does not display anything.

What could be wrong?

I started a new Tabbed Activity project in Android Studio. The fragment content does not show the last Control 'Serial Number'. Below the fragment xml

I have working on apache Cordova application which is for android and ios build. while working with android i have added ionic keyboard which was not necessary. but it didn't give any issue with Android build. but when i working with ios toast and spinner dialogue is not working. One of the other project is working fine with ios and android build.

1. when i removed ionic keyboard from config.xml it wont work at all.
2. again when i use "cordova plugin add ionic-plugin-keyboard --save" this plugin spinner dialogue works but it wont hide again even when i used window.plugins.spinnerDialog.hide();
3. suppose if i have login screen when i click on login button toast notification wont work but when i click to input field in immediately it shows example("Username/pwd invalid "or any relevant msg i written).
4. when i looked into xcode compiler msgs... it says "THREAD WARNING: ['Toast'] took '79.340088' ms. Plugin should use a background thread."

I've created a SlidingTabs with only 2 tabs however the layout is not properly being shown. Image 1 is the output that I always get and Image 2 is the output I'm expect to achieve
