Membuat Aplikasi CRUD Data Mahasiswa Menggunakan RESTful API di Android Studio

Desember 11, 2018 , , , , , , 0 Comments


Pada postingan sebelumnya kita telah membuat API CRUD sederhana menggunakan PHP danMYSQL sekarang kita akan mengkonsumsi API yang sudah kita buat tersebut Pada kasus ini saya akan menggunakan API tadi di Projek Android dengan menggunakan library retrofit



Pertama-tama buat projek baru di Android Studio, kemudian tambahkan library retrofit pada build.gradle(module:app) di bagian  despendencies, kemudian klik sync now
implementation 'com.squareup.retrofit:retrofit:1.9.0'

lalu tambahkan network permission pada AndroidManifest
android:name="android.permission.INTERNET" />

android:name="android.permission.ACCESS_NETWORK_STATE" />

Untuk Susunan Folder nya seperti berikut:
Susunan Folder Projek di Android Studio


Kemudian buat Class BaseApp, kelas ini berfungsi untuk kumpulan perintah yang sering digunakan dalam pembuatan program, sehingga nanti dapat digunakan pada class lain. Berikut kode programnya: untuk ROOT_URL karena saya sudah menguploadnya pada web hosting jadi saya menggunakan url yang ada di web hosting saya, jika anda menyimpanya di localhost dan ingin mengaksesnya dari HP ganti url nya menjadi alamat IP komputer anda, dan pastikan HP dan komputer anda menggunakan jaringan wifi yang sama.
public class BaseApp extends AppCompatActivity {

    public static Context c;

    public static final String ROOT_URL = "http://giviews.000webhostapp.com";

    private static final int DEBUG = 1;

    public SessionManager sessionManager;

    AlphaAnimation btnAnimasi = new AlphaAnimation(1F,0.5F);



    public BaseApp() {

        sessionManager = new SessionManager(c);

    }



    @Override

    protected void onCreate(@Nullable Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        c =  this;

    }



    public void pesan(String a){

        Toast.makeText(c, a, Toast.LENGTH_LONG).show();

    }



    //method untuk menghilangkan action bar

    public void fullScreen(){

        requestWindowFeature(Window.FEATURE_NO_TITLE);

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

                WindowManager.LayoutParams.FLAG_FULLSCREEN);

    }



    private class SessionManager {

        public SessionManager(Context c) {

        }

    }

}

selanjutnya membuat class Model Mahasiswa, Class ini berisi geter dan seter yang nanti akan digunakan ketika get data dan set data mahasiswa, berikut kode programnya:
public class DataMahasiswa {

    private String nim;

    private String nama;

    private String alamat;

    private String jurusan;



    public String getNim() {

        return nim;

    }

    public void setNim(String nim) {

        this.nim = nim;

    }

    public String getNama() {

        return nama;

    }

    public void setNama(String nama) {

        this.nama = nama;

    }

    public String getAlamat() {

        return alamat;

    }

    public void setAlamat(String alamat) {

        this.alamat = alamat;

    }

    public String getJurusan() {

        return jurusan;

    }

    public void setJurusan(String jurusan) {

        this.jurusan = jurusan;

    }

}

kemudian buat Class CDataMahasiswa, berikut kode programnya:
public class CDataMahasiswa {





    private List DataMahasiswa = new ArrayList();



    public List getDataMahasiswa() {

        return DataMahasiswa;

    }



    public void setDataMahasiswa(List DataMahasiswa) {

        this.DataMahasiswa = DataMahasiswa;

    }

}

selanjutnya membuat interface ModuleApi.java berikut kode programnya: Class ini berfungsi untuk mengakses API nya 
interface ModuleAPI {



    //getdata

    @GET("/server_api/view.php")

    public void getDataMahasiswa(Callback callback);



    //update

    @FormUrlEncoded

    @POST("/server_api/update.php")

    public void updateData(

            @Field("vsnim") String vsnim,

            @Field("vsnama") String vsnama,

            @Field("vsalamat") String vsalamat,

            @Field("vsjurusan") String vsjurusan,

            Callback callback);



    //insert

    @FormUrlEncoded

    @POST("/server_api/create.php")

    public void insertData(

            @Field("vsnim") String vsnim,

            @Field("vsnama") String vsnama,

            @Field("vsalamat") String vsalamat,

            @Field("vsjurusan") String vsjurusan,

            Callback callback);



    //delete

    @FormUrlEncoded

    @POST("/server_api/delete.php")

    public void deleteData(

            @Field("vsnim") String vsnim,

            Callback callback);

    }

Selanjutnya Membuat DataMahasiswaActivity.java berikut kode programnya:
public class DataMahasiswaActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener {

    ProgressDialog progressDialog;

    Dialog dialog, dialog2;

    List listdatamahasiswa;

    String strnim, strnama, strjurusan, stralamat;

    ListView listmahasiswa;

    Button update, delete, reset, insert;

    SwipeRefreshLayout swipeRefreshLayout;

    EditText nimmhs, namamhs, alamatmhs, jurusanmhs;

    AdapterCariMahasiswa cariMahasiswa;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_data_mahasiswa);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

        setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);

        fab.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                dialog2 = new Dialog(DataMahasiswaActivity.this);

                dialog2.setTitle("data mahasiswa");

                dialog2.setCanceledOnTouchOutside(false);

                dialog2.setContentView(R.layout.tampilaninsertdata);



                nimmhs = (EditText) dialog2.findViewById(R.id.edtnim);

                namamhs = (EditText) dialog2.findViewById(R.id.edtnama);

                jurusanmhs = (EditText) dialog2.findViewById(R.id.edtjurusan);

                alamatmhs = (EditText) dialog2.findViewById(R.id.edtalamat);





                insert = (Button) dialog2.findViewById(R.id.btninsert);

                reset = (Button) dialog2.findViewById(R.id.btnreset);

                reset.setOnClickListener(new View.OnClickListener() {

                    @Override

                    public void onClick(View v) {

                        nimmhs.setText("");

                        namamhs.setText("");

                        alamatmhs.setText("");

                        jurusanmhs.setText("");



                    }

                });

                insert.setOnClickListener(new View.OnClickListener() {

                    @Override

                    public void onClick(View v) {

                        strnim = nimmhs.getText().toString();

                        strnama = namamhs.getText().toString();

                        strjurusan = jurusanmhs.getText().toString();

                        stralamat = alamatmhs.getText().toString();



                        insertDataMahasiswa();

                        getDataMahasiswa();



                    }

                });

                dialog2.show();

            }

        });



        //inisialisasi

        listmahasiswa = (ListView) findViewById(R.id.listmahasiswa);

        swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh_layout);

        swipeRefreshLayout.setOnRefreshListener(this);

        swipeRefreshLayout.post(new Runnable() {

                                    @Override

                                    public void run() {



                                        getDataMahasiswa();

                                    }

                                }

        );

    }



    private void getDataMahasiswa() {

        overridePendingTransition(0, 0);

        progressDialog = ProgressDialog.show(DataMahasiswaActivity.this, "", " Proses...");

        RestAdapter adapter = new RestAdapter.Builder()

                .setEndpoint(ROOT_URL) //Setting the Root URL

                .build(); //Finally building the adapter



        //Creating object for our interface

        ModuleAPI api = adapter.create(ModuleAPI.class);



        //Calling method to get whether report

        api.getDataMahasiswa(



                new Callback() {

                    @Override

                    public void success(CDataMahasiswa cdataMahasiswa, Response response) {

        swipeRefreshLayout.setRefreshing(false);

        overridePendingTransition(0, 0);

        overridePendingTransition(0, 0);



    }



}

Membuat activity_data_mahasiswa.xml, tambahkan kode berikut:
xml version="1.0" encoding="utf-8"?>

xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context="giviews.id.crud_mahasiswa.DataMahasiswaActivity">



    
        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:theme="@style/AppTheme.AppBarOverlay">



        
            android:id="@+id/toolbar"

            android:layout_width="match_parent"

            android:layout_height="?attr/actionBarSize"

            android:background="?attr/colorPrimary"

            app:popupTheme="@style/AppTheme.PopupOverlay" />



    



    layout="@layout/data_mahasiswa" />



    
        android:id="@+id/fab"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_gravity="bottom|end"

        android:layout_margin="@dimen/fab_margin"

        app:srcCompat="@android:drawable/ic_dialog_email" />


Kemudian data_mahasiswa.xml disini untuk memasukan listviewnya, berikut ini kode nya:
xml version="1.0" encoding="utf-8"?>


    xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:id="@+id/swipe_refresh_layout"

    android:layout_height="match_parent"

    app:layout_behavior="@string/appbar_scrolling_view_behavior"

    tools:showIn="@layout/data_mahasiswa">



    
        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:id="@+id/listmahasiswa">




Membuat AdapterCari Mahasiswa.java, berikut kode programnya:
public class AdapterCariMahasiswa extends BaseAdapter {



    public Context activity;

    private String[] nim, nama, alamat, jurusan;

    public TextView tvnamamahasiswa, tvnim, tvjurusan, tvalamat;

    private static LayoutInflater inflater = null;



    public AdapterCariMahasiswa(DataMahasiswaActivity dataMahasiswaActivity, String[] nim, String[]

            nama, String[] alamat, String[] jurusan) {

        activity = dataMahasiswaActivity;

        this.nim = nim;

        this.nama = nama;

        this.alamat = alamat;

        this.jurusan = jurusan;

    }

    @Override

    public int getCount() {

        return nama.length;

    }



    @Override

    public Object getItem(int position) {

        return position;

    }



    @Override

    public long getItemId(int position) {

        return position;

    }





    @Override

    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater)

                activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        convertView = inflater.inflate(R.layout.layoutlistcarimahasiswa, null);

        tvnamamahasiswa = (TextView) convertView.findViewById(R.id.tvnamamahasiswa);

        tvnim = (TextView) convertView.findViewById(R.id.tvnim);

        tvjurusan = (TextView) convertView.findViewById(R.id.tvjurusan);

        tvalamat = (TextView) convertView.findViewById(R.id.tvalamat);



        tvnamamahasiswa.setText(nama[position].toString());

        tvnim.setText(nim[position].toString());

        tvjurusan.setText(jurusan[position].toString());

        tvalamat.setText(alamat[position].toString());

        return convertView;

    }



}

selanjutnya tambhkan kode berikut pada layoutcarimahasiswa.xml:
xml version="1.0" encoding="utf-8"?>

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:background="#ffffff"

        android:orientation="horizontal">





        
            android:id="@+id/layoutkanan"
