Dinamis RadioButton Android

Alih-alih membuat RadioButton melalui drag and drop dari palet, android juga memfasilitasi Anda untuk membuatnya secara terprogram (dinamis). Untuk membuat RadioButton dinamis, kita perlu menggunakan android.view.ViewGroup.LayoutParams yang mengkonfigurasi lebar dan tinggi tampilan dan mengimplementasikan metode setOnCheckedChangeListener() kelas RadioGroup.

Mari kita lihat contoh Dynamic RadioButton.

* activity_main.xml

File : activity_main.xml

<?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"  
    android:id="@+id/relativeLayout"  
    tools:context="com.example.test.dynamicradiobutton.MainActivity">  
 
</RelativeLayout>  

* Activity class

File : MainActivity.java

package com.example.test.dynamicradiobutton;  
 
import android.support.v7.app.AppCompatActivity;  
import android.os.Bundle;  
import android.widget.RadioButton;  
import android.widget.RadioGroup;  
import android.widget.RelativeLayout;  
 
import android.widget.RelativeLayout.LayoutParams;  
import android.widget.Toast;  
 
public class MainActivity extends AppCompatActivity {  
    RadioGroup rg;  
    RelativeLayout rl;  
    RadioButton rb1,rb2;  
 
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
 
        rg = new RadioGroup(this);  
        rl = (RelativeLayout) findViewById(R.id.relativeLayout);  
        rb1 = new RadioButton(this);  
        rb2 = new RadioButton(this);  
 
        rb1.setText("Male");  
        rb2.setText("Female");  
        rg.addView(rb1);  
        rg.addView(rb2);  
        rg.setOrientation(RadioGroup.HORIZONTAL);  
 
        RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams((int) LayoutParams.WRAP_CONTENT,(int)LayoutParams.WRAP_CONTENT);  
        params.leftMargin =150;  
        params.topMargin = 100;  
 
        rg.setLayoutParams(params);  
        rl.addView(rg);  
 
        rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {  
            @Override  
            public void onCheckedChanged(RadioGroup group, int checkedId) {  
                RadioButton radioButton = (RadioButton) findViewById(checkedId);  
                Toast.makeText(getApplicationContext(),radioButton.getText(),Toast.LENGTH_LONG).show();  
            }  
        });  
    }  
}
