CRUD Data (Volley) part 2


Hello sobat, saya akan memberikan artikel mengenai CRUD data menggunakan library volley yang sebelumnya sudah kita bahas mengenai volley pada artikel sebelumnya yaitu menampilkan data menggunakan recyclerview 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_insert_data.xml
<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
 
    <LinearLayout 
        android:layout_width="match_parent" 
        android:layout_height="match_parent" 
        android:alpha="0.2" 
        android:background="@color/colorAccent" /> 
 
    <LinearLayout 
        android:layout_width="match_parent" 
        android:layout_height="match_parent" 
        android:orientation="vertical" 
        android:padding="10dp"> 
 
        <android.support.design.widget.TextInputLayout 
            android:id="@+id/tilnpm" 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content"> 
 
            <EditText 
                android:id="@+id/etNis" 
                android:layout_width="match_parent" 
                android:layout_height="wrap_content" 
                android:hint="NIS" /> 
        </android.support.design.widget.TextInputLayout> 
 
        <android.support.design.widget.TextInputLayout 
            android:id="@+id/tilnama" 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content"> 
 
            <EditText 
                android:id="@+id/etNama" 
                android:layout_width="match_parent" 
                android:layout_height="wrap_content" 
                android:hint="Nama" /> 
        </android.support.design.widget.TextInputLayout> 
 
        <LinearLayout 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content" 
            android:layout_marginTop="10dp" 
            android:orientation="horizontal"> 
 
            <Button 
                android:id="@+id/btn_cancel" 
                android:layout_width="match_parent" 
                android:layout_height="wrap_content" 
                android:layout_weight="1" 
                android:text="Batal" /> 
 
            <Button 
                android:id="@+id/btn_simpan" 
                android:layout_width="match_parent" 
                android:layout_height="wrap_content" 
                android:layout_weight="1" 
                android:text="Simpan" /> 
 
            <Button 
                android:id="@+id/btn_delete" 
                android:layout_width="match_parent" 
                android:layout_height="wrap_content" 
                android:layout_weight="1" 
                android:text="Hapus" 
                android:visibility="gone" /> 
        </LinearLayout> 
    </LinearLayout> 
</RelativeLayout>
Package Java
Membuat package dengan struktur 



Masukan code pada class InsertData.java
