Airplane mode is an setting in any mobile that suspends all the signal transmitting functions like calls, messaging,DATA connection, Bluetooth, WI-FI etc.in this tutorial is to show you how to switch Airplane mode ON/OFF. In Android Airplane Mode is something like a toggle button, it should be set to 1 - ON, 0 - OFF.
Step 1: Write code into activity_main.xml
<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"
tools:context=".MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<ImageButton
android:id="@+id/tBAirplane"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginTop="104dp"
android:src="@drawable/flightmodeoff" />
</RelativeLayout>
Step 2: Write code into MainActivity.java
package dev.Androidapplink.flightmodeapp;
import dev.Androidapplink.flightmodeapp.R;
import android.os.Build;
import android.os.Bundle;
import android.provider.Settings;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
public class MainActivity extends Activity {
// controls
ImageButton tBAirplane;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tBAirplane = (ImageButton) findViewById(R.id.tBAirplane);
// update UI at first time loading
updateUI(isAirplaneMode());
// set click event for button
tBAirplane.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// check current state first
boolean state = isAirplaneMode();
// toggle the state
if (state)
toggleAirplaneMode(0, state);
else
toggleAirplaneMode(1, state);
// update UI to new state
updateUI(!state);
}
});
}
// Airplane mode version code
@SuppressLint("NewApi")
public void toggleAirplaneMode(int value, boolean state) {
// toggle airplane mode
// check the version
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) { // if
// less
// then
// version
// 4.2
Settings.System.putInt(getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, value);
} else {
Settings.Global.putInt(getContentResolver(),
Settings.Global.AIRPLANE_MODE_ON, value);
}
// broadcast an intent to inform
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", !state);
sendBroadcast(intent);
}
public void updateUI(boolean state) {
// set image according to state
if (state) {
tBAirplane.setImageResource(R.drawable.flightmodeon);
} else {
tBAirplane.setImageResource(R.drawable.flightmodeoff);
}
}
@SuppressLint("NewApi")
public boolean isAirplaneMode() {
// check the version
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {// if
// less
// than
// version
// 4.2
return Settings.System.getInt(getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, 0) != 0;
} else {
return Settings.Global.getInt(getContentResolver(),
Settings.Global.AIRPLANE_MODE_ON, 0) != 0;
}
}
}
