Set focus on an input with Ionic 2

Question

SOLVED :

import { Component, ViewChild} from '@angular/core';
import { Keyboard } from 'ionic-native';


@Component({
  templateUrl: 'build/pages/home/home.html'
})
export class HomePage {
  @ViewChild('input') myInput ;

  constructor() {}

  ionViewDidLoad() {

    setTimeout(() => {
      Keyboard.show() // for android
      this.myInput.setFocus();
    },150);

 }

} 

1) import "ViewChild"

import {Component, ViewChild} from '@angular/core';

2) Create a reference to your input in your html template :

<ion-input #focusInput></ion-input>

3) Use @ViewChild to get access to the input component you just referenced previously.

@ViewChild('focusInput') myInput ;

4) Trigger the focus

Use the ionViewLoaded() method to trigger it each time the view/page is loaded.

setTimeout is needed

  ionViewLoaded() {

    setTimeout(() => {
      Keyboard.show() // for android
      this.myInput.setFocus();
    },150); //a least 150ms.

 }

4) Show the keyboard on Android

import { Keyboard } from 'ionic-native';

Call Keyboard.show() to call the keyboard on Android.

5) Show the keyboard on iOS

add this line to your config.xml to make it work on iOS :

<preference name="KeyboardDisplayRequiresUserAction" value="false" />

Answer 1

You don't need to import the 'Input' from 'angular/core'.

Simply:

import {Component,ViewChild} from '@angular/core';
import {NavController, TextInput } from 'ionic-angular';

@Component({
  templateUrl: 'build/pages/home/home.html'
})
export class HomePage {
  @ViewChild('input') myInput: TextInput;

  constructor(private navCtrl: NavController) { }

  ionViewDidLoad() {

    setTimeout(() => {
      this.myInput.setFocus();
    },150);

 }

} 

And answering comment to Ciprian Mocanu:
