How to open wifi settings in android?

Hello all..

In today’s tutorial I will show you how to open the wifisettings in android programatically.
This code comes handy when the user have not enabled the wifi and you want the user to enable it for your application to work.

Here is the code for that.

package com.coderzheaven;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class OpenWifiSettingsDemo extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button open = (Button)findViewById(R.id.open);
        open.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				openWifiSettings();
			}
		});
    }

    public void openWifiSettings(){

    	final Intent intent = new Intent(Intent.ACTION_MAIN, null);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        final ComponentName cn = new ComponentName("com.android.settings", "com.android.settings.wifi.WifiSettings");
        intent.setComponent(cn);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity( intent);
    }
}

Here is the layout xml- 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:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="How to open Wifi Settings Demo"
    />

  <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Open Wifi settings"
    android:id="@+id/open"
    />
</LinearLayout>
