I'm working on an ionic application. I’m trying to use an infinite-scroll item in a custom component that contains a segement with two Lists that are showen according to the user's choices.
This is the code of the component :
<ion-content *ngIf="show">
<div no-margin no-padding style="color: rgba(25,94,97,0.98)" >
<ion-segment style="color: rgba(25,94,97,0.98)" [(ngModel)]="chx">
<ion-segment-button style="color: rgba(25,94,97,0.98)" value="most">
MOST TRUSTED
</ion-segment-button>
<ion-segment-button style="color: rgba(25,94,97,0.98)" value="recent">
LATEST
</ion-segment-button>
</ion-segment>
</div>
<div no-margin no-padding [ngSwitch]="chx">
<ion-list no-margin no-padding *ngSwitchCase="'most'">
<post-card-most no-margin *ngFor="let post of mostTrusted" [post]="post"> </post-card-most>
<ion-item no-border no-lines align-self-center style="align-content: center; text-decoration-color: grey" *ngIf="isscrollmost" margin-top> <p style="text-align: center; color: grey"> No data to display... </p></ion-item>
<ion-infinite-scroll (ionInfinite)="doInfinite2($event)" threshold="100px">
<ion-infinite-scroll-content
loadingSpinner="{{'BUBBLES' | translate}}"
loadingText="{{'LOADING' | translate}}">
</ion-infinite-scroll-content>
</ion-infinite-scroll>
</ion-list>
<ion-list no-margin no-padding *ngSwitchCase="'recent'">
<page-post-card no-margin *ngFor="let post of latestTrusted" [post]="post" [isNotif]=false [home]=false>
</page-post-card>
<ion-item no-border no-lines align-self-center style="align-content: center; text-decoration-color: grey" *ngIf="isscrollrecent" margin-top> <p style="text-align: center; color: grey"> No data to display... </p></ion-item>
<ion-infinite-scroll (ionInfinite)="doInfinite($event)" threshold="100px">
<ion-infinite-scroll-content
loadingSpinner="{{'BUBBLES' | translate}}"
loadingText="{{'LOADING' | translate}}">
</ion-infinite-scroll-content>
</ion-infinite-scroll>
</ion-list>
</div>
</ion-content>
The component is used in an ionic page like this:
<ion-content no-padding>
<topicsearch [show]="showresult"></topicsearch> <!-- This is the custom component -->
<div *ngIf="!showresult" >
<ion-list *ngFor="let top of topics">
<ion-item (click)="topicsearchselected(top.label)" > {{top?.label}}</ion-item>
</ion-list>
</div>
</ion-content>
The problem is that the infinite-scroll doesn’t fire when scrolling down in the custom component.
Does anyone have a solution for that ?
Your component using ion-content which including inside another ion-content. Remove ion-content from component.
And also doInfinite function will be declared inside the component ts.

Having problems trying to nest lists, I expected them to be inset the further down they go, but instead I've got a complete mess as you can see in the screenshot below.
Here's the code:
<ion-content padding>
<div *ngIf="categories && categories.length > 0; then validContent else noContent"></div>
<ng-template #validContent>
<p>Please select the categories you wish to receive content for.</p>
<form (ngSubmit)="processForm($event)" id="userForm" class="ssp__form">
<ion-list lines="none" no-padding>
<ion-item lines="none" *ngFor="let category of categories">
<ion-label>{{ category.name }}</ion-label>
<ion-checkbox [name]="category.slug" [(ngModel)]="submissionData[category.term_id]"></ion-checkbox>
<ion-list inset="true" style="width:100%;" lines="none" no-padding *ngIf="category.children.length > 0">
<ion-item *ngFor="let subCategory of category.children">
<ion-label>{{ subCategory.name }}</ion-label>
<ion-checkbox [name]="subCategory.slug" [(ngModel)]="submissionData[subCategory.term_id]"></ion-checkbox>
</ion-item>
</ion-list>
</ion-item>
</ion-list>
<ion-button type="submit" style="width:100%;" color="primary" expand="block">Save Categories</ion-button>
</form>
</ng-template>
<ng-template #noContent>
<ion-card>
<ion-card-header>
<ion-card-title style="text-align: center; font-size: 14px;">No Categories Found.</ion-card-title>
</ion-card-header>
<ion-card-content>
<p style="text-align: center">There are no categories for you to read at this time.</p>
</ion-card-content>
</ion-card>
</ng-template>
</ion-content>
I have referred this example from ionic framework documentation and created a segment of my own.
<div padding>
<ion-segment [(ngModel)]="pet">
<ion-segment-button value="kittens">
Kittens
</ion-segment-button>
<ion-segment-button value="puppies">
Puppies
</ion-segment-button>
</ion-segment>
</div>
<div [ngSwitch]="pet">
<ion-list *ngSwitchCase="'puppies'">
<ion-item>
<ion-thumbnail item-start>
<img src="img/thumbnail-puppy-1.jpg">
</ion-thumbnail>
<h2>Ruby</h2>
</ion-item>
...
</ion-list>
<ion-list *ngSwitchCase="'kittens'">
<ion-item>
<ion-thumbnail item-start>
<img src="img/thumbnail-kitten-1.jpg">
</ion-thumbnail>
<h2>Luna</h2>
</ion-item>
...
</ion-list>
</div>
Here, they are displaying different ion-list on different button clicks.
But I am a different element type to be displayed on two different button clicks.
Here is my code-
<div>
<ion-segment [(ngModel)]="pet">
<ion-segment-button value="audios">
Audios
</ion-segment-button>
<ion-segment-button value="images">
Images
</ion-segment-button>
</ion-segment>
</div>
<div [ngSwitch]="pet">
//this is coming
<ion-list *ngSwitchCase="'audios'">
<p align="left">
Resources
</p>
<ion-item-divider>
Category Name
</ion-item-divider>
<ion-item class="custom-font-size">
<i class="material-icons rotate theme-color" item-start> format_align_center</i>

</ion-item>
<ion-item class="custom-font-size">
<ion-icon name="md-play" class="play-icon-color" item-start></ion-icon>

</ion-item>
<ion-item class="custom-font-size">

</ion-item>
</ion-list>
//this is not coming
<ion-grid *ngSwitchCase="'images'">
<div *ngFor="let images of image; let i = index;">
<ion-row *ngIf="i % 3 === 0">
<ion-col col-4 *ngIf="i < images.length">
<img [src]="images[i].url" />
</ion-col>
<ion-col col-4 *ngIf="i+1 < images.length">
<img [src]="images[i+1].url" />
</ion-col>
<ion-col col-4 *ngIf="i+2 < images.length">
<img [src]="images[i+2].url" />
</ion-col>
</ion-row>
</div>
</ion-grid>
</div>
in .ts file i have stored images as
this.image = [
{ url: 'assets/imgs/placeholder.png'},
{ url: 'assets/imgs/placeholder.png' },
{ url: 'assets/imgs/placeholder.png' }
];
As you can see i want to display a ion-list on first segment button click and display a image grid on second segment button click. As of now nothing comes up when i click on the second button
I think you're for loop is not correct, You are using the loop and inside it, you are trying to use an index on each item which is not an array. Below code should be working
<div>
<ion-segment [(ngModel)]="pet">
<ion-segment-button value="audios">
Audios
</ion-segment-button>
<ion-segment-button value="images">
Images
</ion-segment-button>
</ion-segment>
</div>
<div [ngSwitch]="pet">
<ion-list *ngSwitchCase="'audios'">
<p align="left">
Resources
</p>
<ion-item-divider>
Category Name
</ion-item-divider>
<ion-item class="custom-font-size">
<i class="material-icons rotate theme-color" item-start> format_align_center</i>
Lemon Exercise<span item-end>08:12</span>
</ion-item>
<ion-item class="custom-font-size">
<ion-icon name="md-play" class="play-icon-color" item-start></ion-icon>
Sample Goal Audio<span item-end>04:11</span>
</ion-item>
<ion-item class="custom-font-size">
<ion-icon name="md-play" class="play-icon-color" item-start></ion-icon>

I would like to have an ion-item inside a list with a word centered between two icons (one on left side and one on right side) like this:
I'm not able to achieve this goal, because I have something like that:
This is my code:
<ion-list>
<ion-item class="item item-icon-left item-icon-right" style="text-align: center">
<ion-icon item-left name="lock"></ion-icon>
<b>Woman</b>
<ion-icon item-right name="lock"></ion-icon>
</ion-item>
How can I have something like in the first image where the text it's centered correctly?
You can use text-align property for center your text like below
<ion-list>
<ion-item class="item item-icon-left item-icon-right" style="text-align: center">
<ion-icon item-left name="lock"></ion-icon>
<ion-label class="centerlabel">Woman</ion-label>
<ion-icon item-right name="lock"></ion-icon>
</ion-item>
SCSS
.centerlabel {
text-align: center;
}
Hope this will helps!

<ion-list>
<ion-item>
<ion-row>
<ion-col col-1 style="text-align: left;">
<ion-icon name="lock"></ion-icon>
</ion-col>
<ion-col col-10 style="text-align: center;">
<b>Woman</b>
</ion-col>
<ion-col col-1 style="text-align: right;">
<ion-icon name="lock"></ion-icon>
</ion-col>
</ion-row>
</ion-item>
</ion-list>
try this
<ion-list>
<ion-item >
<ion-icon item-left name="lock"></ion-icon>
<div text-center><b style="margin-left: -20px;">Woman</b></div>
<ion-icon item-right name="lock"></ion-icon>
</ion-item>
</ion-list>
I've been trying to use ion-cards using ion dark theme, and I can't actually see the text;
I tried to change the CSS with this:
h2,p {
color:white;
}
and it's still black.
I took the code right from ionic documentation:
<ion-card class="col-md-4" *ngFor="let new of news;let i=index">
<ion-item>
<ion-avatar item-left>
<img [src]="new.image_url" *ngIf="new.image_url">
</ion-avatar>
<h2>TEST</h2>
<p>AA TEST</p>
</ion-item>
<ion-card-content>
<p>
TSET SUMMARY
</p>
</ion-card-content>
<ion-row>
<ion-col>
<button ion-button icon-left clear small>
<ion-icon name="thumbs-up"></ion-icon>
<div>12 likes</div>
</button>
</ion-col>
</ion-row>
</ion-card>
Any ideas?
You can overwrite the ionic variable itself. Navigate the ./theme/variables.scss and add
$card-ios-text-color(#fff);
$card-md-text-color(#fff);
$card-wp-text-color(#fff);
All the ionic variables can be found here for quick reference
I want to change the background color of this menu to the color of the title bar color. (Orange color) ("bar-assertive")

I Found the answer.
in style.css changed the default values
.menu-right ion-content,.menu-right .item-complex .item-content{
color:#000000;
background-color: #EF473A;
}
