Assalamuallaikum wr.wb .......
Pada postingan kali ini kita akan belajar bersama mengenal apa itu Listview ,
okee,,,ListView adalah tampilan beberapa item dalam bentuk list yang dapat di scroll secara vertikal. Setiap item akan otomatis dimasukkan kedalam list menggunakan Adapter yang datanya di ambil dari array/database/json/dsb. ListView sering digunakan dalam aplikasi Android, seperti kontak, email, twitter.
Postingan ini saya buat untuk memenuhi salah satu tugas kuliah pada mata pelajaran Mobile Programming .
Disini saya coba membuat contoh Listview dari beberapa bahasa pemrogaraman
langsung saja kita mulai .....
1.Onboarding /splash screen
Java Onboarding
package com.example.yuresa_161021450043;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.util.Log;
public class onboarding extends AppCompatActivity {
private static int SplashDuration = 3000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_onboarding);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
try {
Intent intent = new Intent(getBaseContext(), form_login.class);//StartSlider,MainActivity
startActivity(intent);
finish();
} catch (Exception e){
Log.e("Splash error",e.getMessage());
Intent intent = new Intent(onboarding.this, form_login.class); //MainActivity.class
startActivity(intent);
}
}
}, SplashDuration);
}
}
Xml Onboarding
