Praktikum ke 4 | Membuat ListAdapter

Disini saya akan membuat aplikasi ListAdapter, Berikut ini saya akan membuat projectnya :
Nama Project : Percobaan
Nama Package : com.percobaan
Nama Class : MainActivity.java
Nama Class ke 2 : Array3.java
Nama Layout : activity_main.xml
Nama Layout ke 2 : row.xml

berikut ini source code activity_main.xml :

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <TabWidget android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            />
        <FrameLayout android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            >
            <ListView android:id="@+id/almag"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                />
            <TableLayout android:id="@+id/details"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:stretchColumns="1"
                android:paddingTop="4px"
                >
                <TableRow>
                    <TextView android:text="Nama: " />
                    <EditText android:id="@+id/nama" />
                </TableRow>

                <TableRow>
                    <TextView android:text="Jekel" />
                    <RadioGroup android:id="@+id/jekel">
                        <RadioButton android:id="@+id/pria"
                            android:text="Pria"
                            />
                        <RadioButton android:id="@+id/perempuan"
                            android:text="Perempuan"
                            />
                    </RadioGroup>
                </TableRow>

                <TableRow>
                    <TextView android:text="Alamat:" />
                    <EditText android:id="@+id/alamat" />
                </TableRow>

                <Button android:id="@+id/save"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:text="Save"
                    />
            </TableLayout>
        </FrameLayout>
        </LinearLayout>
        </TabHost>

Hasil layout activity_main.xml :

Setelah Membuat activity_main.xml, sekarang membuat row.xml, berikut source code row.xml :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="4px" >

    <ImageView
        android:id="@+id/icon"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentTop="true"
        android:layout_marginRight="4px" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/title"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:ellipsize="end"
            android:gravity="center_vertical"
            android:singleLine="true"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/alamat"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:ellipsize="end"
            android:gravity="center_vertical"
            android:singleLine="true" />
    </LinearLayout>

</LinearLayout>

Hasil Layout row.xml :

Sekarang kita pergi ke Class, sekarang kita menambahkan source code pada Class MainActivity.java :

package com.percobaan;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity {

    private String nama="";
    private String alamat="";
    private String jekel="";
    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 getJekel() {
    return(jekel);
    }
    public void setJekel(String jekel) {
    this.jekel=jekel;
    }
    public String toString() {
        return(getNama());
    }

    }

Dan sekarang kita akan Menambahkan source code pada Class Array3.java :

package com.percobaan;

import android.app.TabActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.view.LayoutInflater;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.RadioGroup;
import android.widget.TabHost;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.List;

public class array3 extends TabActivity {
    List<MainActivity> model = new ArrayList<MainActivity>();
    almagAdapter adapter = null;
    EditText nama = null;
    EditText alamat = null;
    RadioGroup jekel = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        nama = (EditText) findViewById(R.id.nama);
        alamat = (EditText) findViewById(R.id.alamat);
        jekel = (RadioGroup) findViewById(R.id.jekel);
        Button save = (Button) findViewById(R.id.save);
        save.setOnClickListener(onSave);
        ListView list = (ListView) findViewById(R.id.almag);
        adapter = new almagAdapter();
        list.setAdapter(adapter);
        TabHost.TabSpec spec = getTabHost().newTabSpec("tag1");
        spec.setContent(R.id.almag);
        spec.setIndicator("List", getResources().getDrawable(R.drawable.list));
        getTabHost().addTab(spec);
        spec = getTabHost().newTabSpec("tag2");
        spec.setContent(R.id.details);
        spec.setIndicator("Details",
                getResources().getDrawable(R.drawable.alamat));
        getTabHost().addTab(spec);
        getTabHost().setCurrentTab(0);
        list.setOnItemClickListener(onListClick);
    }

    private View.OnClickListener onSave = new View.OnClickListener() {
        public void onClick(View v) {
            MainActivity r = new MainActivity();
            r.setNama(nama.getText().toString());
            r.setAlamat(alamat.getText().toString());
            switch (jekel.getCheckedRadioButtonId()) {
            case R.id.pria:
                r.setJekel("Pria");
                break;
            case R.id.perempuan:
                r.setJekel("Perempuan");
                break;
            }
            adapter.add(r);
        }
    };
    private AdapterView.OnItemClickListener onListClick = new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            MainActivity r = model.get(position);
            nama.setText(r.getNama());
            alamat.setText(r.getAlamat());
            if (r.getJekel().equals("Pria")) {
                jekel.check(R.id.pria);
            } else if (r.getJekel().equals("Perempuan")) {
                jekel.check(R.id.perempuan);

            }
            getTabHost().setCurrentTab(1);
        }
    };

    class almagAdapter extends ArrayAdapter<MainActivity> {
        almagAdapter() {
            super(array3.this, R.layout.row, model);
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            View row = convertView;
            almagHolder holder = null;
            if (row == null) {
                LayoutInflater inflater = getLayoutInflater();
                row = inflater.inflate(R.layout.row, parent, false);
                holder = new almagHolder(row);
                row.setTag(holder);
            } else {
                holder = (almagHolder) row.getTag();
            }
            holder.populateFrom(model.get(position));
            return (row);
        }
    }

    static class almagHolder {
        private TextView nama = null;
        private TextView alamat = null;
        private ImageView icon = null;
        private View row = null;

        almagHolder(View row) {
            this.row = row;
            nama = (TextView) row.findViewById(R.id.title);
            alamat = (TextView) row.findViewById(R.id.alamat);
            icon = (ImageView) row.findViewById(R.id.icon);
        }

        void populateFrom(MainActivity r) {
            nama.setText(r.getNama());
            alamat.setText(r.getAlamat());
            if (r.getJekel().equals("Pria")) {

                icon.setImageResource(R.drawable.pria);
            } else if (r.getJekel().equals("Perempuan")) {
                icon.setImageResource(R.drawable.perempuan);
            }
        }
    }
}

Selmat Mencoba ^_^

Praktikum 4 | membuat ArrayAdapter

Praktikum kali ini saya telah membuat aplikasi ArrayAdapter.
Pertama saya membuat dulu Projectnya :
Nama Project : Percobaan1
Nama Package : com.percobaan2.array2
Nama Class : Almag.java
Nama Class ke 2 : Array2.java
Nama Layout : Main.xml

Berikut ini source code Main.xml :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <TableLayout android:id="@+id/details"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:stretchColumns="1" >

    <TableRow>
        <TextView android:text="Name:" />
        <EditText android:id="@+id/nama"/>
    </TableRow>

    <TableRow>
        <TextView android:text="Jekel" />
        <RadioGroup android:id="@+id/jekel">
            <RadioButton android:id="@+id/pria"
                android:text="Pria"
                />
            <RadioButton android:id="@+id/perempuan"
                android:layout_width="wrap_content"
                android:text="Perempuan"
                />
        </RadioGroup>
    </TableRow>

    <TableRow>
        <TextView android:text="ALamat :" />
        <EditText android:id="@+id/alamat" />
    </TableRow>

    <Button android:id="@+id/save"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Save"
        />
    </TableLayout>
    <ListView android:id="@+id/almag"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_above="@id/details"
        />

</RelativeLayout>

Hasil Tampilan Layout :

Dan sekarang Source code Almag.java. Sebagai Berikut ini :

package com.percobaan.array2;

public class Almag {

    private String nama="";
    private String alamat="";
    private String jekel="";

    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 getJekel() {
        return(jekel);
    }
    public void setJekel(String jekel) {
        this.jekel=jekel;
    }
    public String toString() {
        return(getNama());
    }
}

Setelah Source code di Class Almag.java sekarang Membuat source Code pada Class Array2.java. sebegai berikut :

package com.percobaan.array2;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.RadioGroup;
import java.util.ArrayList;
import java.util.List;

public class Array2 extends Activity{
    List<Almag> model=new ArrayList<Almag>();
    ArrayAdapter<Almag> adapter=null;

    @Override
public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button save=(Button)findViewById(R.id.save);

        save.setOnClickListener(onSave);

        ListView list=(ListView)findViewById(R.id.almag);
        adapter=new ArrayAdapter<Almag>(this,android.R.layout.simple_list_item_1,model);
        list.setAdapter(adapter);
    }

    private View.OnClickListener onSave=new View.OnClickListener() {


        public void onClick(View v) {
            Almag r=new Almag();
            EditText nama=(EditText)findViewById(R.id.nama);
            EditText alamat=(EditText)findViewById(R.id.alamat);

            r.setNama(nama.getText().toString());
            r.setAlamat(alamat.getText().toString());

            RadioGroup jekel=(RadioGroup)findViewById(R.id.jekel);

            switch (jekel.getCheckedRadioButtonId()) {
            case R.id.pria:
                r.setJekel("pria");
                break;

            case R.id.perempuan:
                r.setJekel("perempuan");
                break;


        }

            adapter.add(r);
    }

    };

}

Dan sekarang kita tinggal Running Hasilnya :

Selamat Mencoba ^_^ !!!!

Spinner

Praktikum kali ini saya telah membuat aplikasi sederhana yaitu Spinner. Seperti biasa buatlah Projectnya terlebih Dahulu. Nama Project RadioButton. Package Name :android.spinner. Activity Name :SpinnerView.java. Layout Name : main.xml. Berikut Source code main.xml :

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

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

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

<TextView

android:id="@+id/selection"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

<Spinner android:id="@+id/spinner"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:drawSelectorOnTop="true"

<Button

android:id="@+id/bpilih"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_below="@+id/spinner"

android:layout_marginTop="5dp"

android:text="Pilih"

android:textSize="18sp" />

<TextView android:id="@+id/thasil"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@+id/bpilih"

android:layout_below="@+id/bpilih"

android:layout_marginTop="30dp"

android:text="Spinner yang dipilih adalah?"

android:textAppearance="?android:attr/textAppearanceLarge"

</LinearLayout>

Hasil main.xml

Berikut source code di class SpinnerView.java :

package android.spinner;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.widget.AdapterView;

import android.widget.ArrayAdapter;

import android.widget.Button;

import android.widget.Spinner;

import android.widget.TextView;

public class SpinnerView extends Activity implements AdapterView.OnItemSelectedListener {

// untuk menampilkan daftar item

TextView h;

String[] items = { "JAVA", "PHP", "ANDROID" };

Button k;

Spinner s;

@Override

public void onCreate(Bundle icicle) {

super.onCreate(icicle);

setContentView(R.layout.main);

k = (Button)findViewById(R.id.bpilih);

// untuk memanggil id selection dan spinner dari file xml

h = (TextView) findViewById(R.id.thasil);

k = (Button) findViewById(R.id.bpilih);

s = (Spinner) findViewById(R.id.spinner);

k.setOnClickListener(new ok());

s.setOnItemSelectedListener(this);

// untuk menampilkan daftar item

ArrayAdapter<String> araybaru = new ArrayAdapter<String>(this,

android.R.layout.simple_spinner_item, items);

araybaru.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

s.setAdapter(araybaru);

}

public void onItemSelected(AdapterView<?> parent, View v, int position,

long id) {

}

public void onNothingSelected(AdapterView<?> parent) {

h.setText("");

}

class ok implements Button.OnClickListener {

public void onClick(View v) {

String a = (String) ("Pilihan anda adalah : "+s.getSelectedItem());

h.setText(a);

}

Inilah Hasil Runnig Spinner :
