Hello sobat, saya akan memberikan artikel mengenai CRUD data pada databases menggunakan library Realms yang sebelumnya sudah kita bahas mengenai realms pada artikel sebelumnya dan sekarang masuk ke part 2 mengenai CRUD yaitu Tambah, Ubah dan Hapus data, untuk langkah-langkahnya,

Langkah PART 1 

Design Layout
Membuat layout dengan struktur



Masukan code xml pada activity_add.xml sesuai dengan struktur diatas


<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context=".activity.AddActivity"> 
 
    <LinearLayout 
        android:layout_width="match_parent" 
        android:layout_height="wrap_content" 
        android:orientation="vertical"> 
 
        <EditText 
            android:id="@+id/inputNis" 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content" 
            android:layout_marginBottom="10dp" 
            android:hint="Masukan Nis" /> 
 
        <EditText 
            android:id="@+id/inputNama" 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content" 
            android:hint="Masukan Nama" /> 
 
        <LinearLayout 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:layout_gravity="center" 
            android:layout_marginTop="20dp" 
            android:orientation="horizontal"> 
 
            <Button 
                android:id="@+id/delete" 
                android:layout_width="wrap_content" 
                android:layout_height="wrap_content" 
                android:layout_gravity="center" 
                android:text="Hapus" 
                android:visibility="gone" /> 
 
            <Button 
                android:id="@+id/save" 
                android:layout_width="wrap_content" 
                android:layout_height="wrap_content" 
                android:text="Simpan" /> 
        </LinearLayout> 
    </LinearLayout> 
</RelativeLayout>

Package Java
Masukan class dengan struktur



Masukan source code berikut di AddActivity.java sesuai dengan struktur diatas


package com.codetr.tanwir.databasesrealm.activity; 
 
import android.content.Intent; 
import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
 
import com.codetr.tanwir.databasesrealm.R; 
import com.codetr.tanwir.databasesrealm.helper.RealmHelper; 
 
public class AddActivity extends AppCompatActivity { 
 
    private RealmHelper realmHelper; 
    private EditText inputNama; 
    private EditText inputNis; 
    private Button save; 
 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.activity_add); 
        setTitle("Tambah Siswa"); 
 
        realmHelper = new RealmHelper(AddActivity.this); 
        inputNis = (EditText) findViewById(R.id.inputNis); 
        inputNama = (EditText) findViewById(R.id.inputNama); 
        save = (Button) findViewById(R.id.save); 
 
        save.setOnClickListener(new View.OnClickListener() { 
            @Override 
            public void onClick(View v) { 
                String nis, nama; 
                nis = inputNis.getText().toString(); 
                nama = inputNama.getText().toString(); 
                realmHelper.addSiswa(nis, nama); 
                finish(); 
                Intent i = new Intent(AddActivity.this, MainActivity.class); 
                startActivity(i); 
            } 
        }); 
    } 
}

Output Aplikasi
