Develop android weather app with Material Design

This post describes how to create a material android weather app using material design guidelines. Google Material Design is a set of rules for visual design, UI interaction, motion and so on. These rules help developer when they design and create an Android app.
This post describes how we create an Android weather app using Weatherlib as weather layer and Material design rules. We want to develop this app not only for Android 5 Lollipop that supports Material design natively but we want to support the previous version of Android like 4.x KitKat.

As you may already know, there are several Android Weather API that provides weather information for free. Using Weatherlib you can make your app working with different weather providers writing your code only one time.

If you want to download directly the Android source code of this Android weather app without reading the tutorial this is the link:

For that reason, we will introduce appCompat v7 library that helps us to implement the Material Design even in the previous Android versions.

Our material android weather app should have an extended Toolbar that holds some information about the location and current weather and some basic weather information about temperature, weather icon, humidity, wind and pressure. At the end we will get something like the pic shown below:

Material Android weather app: Project set up

The first thing we have to do is configuring our project so that we can use Weatherlib and especially appCompat v7. We can open build.graddle and add these lines:

[java]dependencies {
compile fileTree(dir: ‘libs’, include: [‘*.jar’])
compile ‘’
compile ‘’
compile ‘com.survivingwithandroid:weatherlib:1.6.0’
compile ‘com.survivingwithandroid:weatherlib_volleyclient:1.6.0’

Now we have our project correctly set up, we can start defining our app layout.

App layout: Google Material design

As briefly explained before, we want to use the Toolbar in our case the extended toolbar. a Toolbar is action bar generalization that gives us more control. Differently from Action bar that is tightly bound to an Actvitiy, a Toolbar can be placed everywhere inside the View hierarchy.

So our layout will be divided in three main areas:

  • Toolbar area
  • Weather icon and temperature
  • Other weather data

The layout is shown below:

[xml]<RelativeLayout xmlns:android=""



As you can see we used Toolbar. We set the toolbar height equals to 128dp as stated in the guidelines, moreover we used the primary color as background. The primary color is defined in colors.xml. You can refer to material design color guidelines for more information. We should define at least three different color:

  • The primary color, identified by 500
  • The primary dark color identified by 700
  • Accent color that should be for primary action buttons and so on

Our toolbar background color is set to primary color.

<color name="primaryColor_500">#03a9f4</color>
<color name="primaryDarkColor_700">#0288d1</color>

Moreover the left padding and the bottom padding inside the toolbar are defined according to the guidelines. At the end we add the menu items as we are used to do with action bar. The main result is shown below:

Search city: Popup with Material Design

We can use the popup to let the user to enter the location. The popup is very simple, it is made by a EditText that is used to enter the data and a simple ListView that shows the city that match the pattern inserted in the EditText. I will not cover how to search a city in weatherlib because i already covered it. The result is shown here:

The popup layout is very shown below:

[xml]<LinearLayout xmlns:android=""
android:orientation="vertical" android:layout_width="match_parent"






The code to create and handle the dialog is shown below:

[java]private Dialog createDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = this.getLayoutInflater();
View v = inflater.inflate(R.layout.select_city_dialog, null);

EditText et = (EditText) v.findViewById(;
et.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (count > 3) {
// We start searching
weatherclient.searchCity(s.toString(), new WeatherClient.CityEventListener() {
public void onCityListRetrieved(List&lt;City&gt; cities) {
CityAdapter ca = new CityAdapter(WeatherActivity.this, cities);


builder.setPositiveButton("Accept", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// We update toolbar
toolbar.setTitle(currentCity.getName() + "," + currentCity.getCountry());
// Start getting weather

builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {

return builder.create();

An important thing to notice it is at line 33, where we set the toolbar title according to the city selected by the user and then we get the current weather. The result of this piece of code is shown here:

Weatherlib: weather

To get the current weather we use Weatherlib:

[sociallocker] [java]private void getWeather() {
weatherclient.getCurrentCondition(new WeatherRequest(currentCity.getId()),
new WeatherClient.WeatherEventListener() {
public void onWeatherRetrieved(CurrentWeather currentWeather) {
// We have the current weather now
// Update subtitle toolbar

[/java] [/sociallocker]

You can notice at line 8 we set the toolbar subtitle according to the current weather while at line 15 we change the toolbar color according to the current temperature. As toolbar background color we used the primary colors shown in the guidelines. The picture below shows the final result of the android material weather app.

how to implement android weather app using materil design
Do you know you can build your weather station? It is easy and in the post named Tweets from Arduino temperature and pressure data you can find all the details to build your personal weather station that can monitor your room temperature and pressure and send information via twitter. Give a look.


This is interesting isn’t? But….you can create your weather station using Arduino and learn IoT Arduino Programming. Arduino with sensors can measure the atmospheric temperature and pressure.

At the end of this post, you gained the knowledge about how to implement android material weather app with a step by step tutorial. You can customize the app and implement it in the way you like.
