Layout Creation

Create an interface with the following components and layouts:

RelativeLayout
TextView
RadioButton
RadioGroup

Open activity_main.xml then type the following codes:

<?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:id="@+id/activity_main"
android:padding="15dp">
<TextView
android:text="Club sepak bola yang memenangkan liga champions adalah :"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textView"
android:textSize="25sp"
android:textColor="@android:color/black"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:textStyle="bold"/>
<RadioGroup
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView"
android:layout_centerHorizontal="true"
android:layout_marginTop="39dp"
android:id="@+id/radioGroup" >
<RadioButton
android:text="Real Madrid"
android:foreground="?attr/selectableItemBackground"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/radioButton"
android:onClick="onRadioButton"
android:layout_toLeftOf="@+id/radioGroup"
android:layout_toStartOf="@+id/radioGroup"
android:layout_below="@+id/radioGroup"/>
<RadioButton
android:text="Liverpool"
android:foreground="?attr/selectableItemBackground"
android:onClick="onRadioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/radioButton"
android:layout_alignLeft="@+id/radioButton"
android:layout_alignStart="@+id/radioButton"
android:layout_marginTop="36dp"
android:id="@+id/radioButton2"/>
<RadioButton
android:text="Barcelona"
android:foreground="?attr/selectableItemBackground"
android:onClick="onRadioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="26dp"
android:id="@+id/radioButton3"
android:layout_below="@+id/radioButton2"
android:layout_alignLeft="@+id/radioButton2"
android:layout_alignStart="@+id/radioButton2"/>
<RadioButton
android:text="Juventus"
android:foreground="?attr/selectableItemBackground"
android:onClick="onRadioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/radioButton3"
android:layout_alignLeft="@+id/radioButton3"
android:layout_alignStart="@+id/radioButton3"
android:layout_marginTop="39dp"
android:id="@+id/radioButton4"/>
</RadioGroup>
</RelativeLayout>

Make sure you enter the programming code correctly then a layout will be formed as shown below:

5. Java Coding

Next step is give commands to the components that have been formed in activity_main.xml. Open MainActivity.java then enter the code below:

package badoystudio.com.kuissederana;

import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

AlertDialog.Builder builder;
RadioGroup radiogroup;
//deklarasi var or obj

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

//radiogroup inisialisasi
radiogroup = (RadioGroup) findViewById(R.id.radioGroup);

}

//Memilih RadioButton

public void onRadioButton(View view) {

Boolean checked = ((RadioButton) view).isChecked();

switch (view.getId()) {
case R.id.radioButton:
if (checked)
tampilDialog();
break;

case R.id.radioButton2:
if (checked)
jawabanSalah();
break;
case R.id.radioButton3:
if (checked)
jawabanSalah();
break;
case R.id.radioButton4:
if (checked)
jawabanSalah();
break;
}

}

//menampilkan dialog
public void tampilDialog() {

builder = new AlertDialog.Builder(this);
builder.setCancelable(false);
builder.setTitle("Selamat !!!");
builder.setMessage("Jawaban kamu benar : Real Marid");
builder.setPositiveButton("OKE",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Toast.makeText(MainActivity.this, "Selamat", Toast.LENGTH_SHORT).show();
}
});

builder.setNegativeButton("ULANGI", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
radiogroup.clearCheck();
}
});

builder.create().show();

}
//menampilkan toast text jawaban salah
public void jawabanSalah(){

Toast.makeText(this, "Jawaban kamu Salah", Toast.LENGTH_SHORT).show();
}
}
