Android Dynamic RadioButton
Rather than making RadioButton through intuitive from
palette, android likewise encourages you to make it automatically (powerfully).
For making dynamic RadioButton, we have to utilize
android.view.ViewGroup.LayoutParams which designs the width and stature of
perspectives and actualizes setOnCheckedChangeListener() strategy for
RadioGroup class.
Example Of Dynamic RadioButton
Let’s See an example of 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();
}
});
}
}
