How to Implement Splash Screen in AndroidAndroid Development

What is a SplashScreen?

A splash screen is a screen that appears when you open an app on your mobile device. So, we can say that it is the first impression for the user. It is commonly used to show an application logo or an image associated with an application.

Implementation

So instead of using a layout file, we'll refer to the splash screen as the background of the activity theme. first, create an XML drawable splash_background.xml inside the res/drawable folder in

<?xml version="1.0" encoding="utf-8"?> 

   <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:drawable="@color/white" />
   <item android:drawable="@drawable/ic_icon_vector" android:gravity="center" />

</layer-list>

next step, set splash_groundground.xml as the background for your splash activity in the theme. Add a new splash to your splash activity.

<!-- Splash Screen theme. -->
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">@drawable/splash_background></item>
</style>

Add your theme to AndroidManifest.xml as your splash activity theme.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.exmple.splash">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme">

        <activity
            android:name=".SplashActivity"
            android:theme="@style/SplashTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest></pre><div>
}

Create a blank activity for SplashActivity.java without XML. This class will only redirect to MainActivity.java.

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        startActivity(new Intent(SplashActivity.this, MainActivity.class));
        finish();
    }
}

How to Create Custom CardView in AndroidAndroid Development

Cardview is a widget provided by Android to create a new look and functional UI. You can build your app with the following examples to make it look more professional. Cardview is a wonderful concept that makes your user experience better than the Android UI. Cardview is an Android Lollipop released with Android 5.0.

Customized CardView

First, add a CardView dependency to the application-level build.gradle file.

dependencies {     
implementation
‘androidx.cardview:cardview:1.0.0’
}

Then create a drawable background for the cards. For that, create a new drawable resource file inside the drawable folder.
res > drawable > New > Drawable Resource File.

background1.xml

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android">

background2.xml

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android">

Select2

background3.xml

<?xml version="1.0" encoding="utf-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android">

Now create a card view in the main XML file. Here I used LinearLayout as the root widget, after using the card view. Below the codes that give you an idea of how to customize the card.
You can change it according to your needs.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

How create a sitemap for your Gatsby siteGatsby

We are adding a sitemap in our all site pages for making sure search engines (such as Google) can find and crawl them all.

So, I will show you how to set a sitemap on the Gatsby site.

Using gatsby-plugin-sitemap

To generate an XML sitemap, you will use the gatsby-plugin-sitemap package.

Install the package by running the following command: npm install gatsby-plugin-sitemap

How to configure

Once the installation is complete, you can now add this plugin to your gatsby-config.js, like so:

Configure siteUrl and add this {resolve: gatsby-plugin-sitemap} into the plugins array. code looks like

module.exports = {
  siteMetadata: {

How To Grow Your Business - 1Sales

Introduction

You can only develop products and services that are very effective if you pay attention to the needs of your customers and prospects. One way to understand exactly what your customers want is through research and surveys.

1. Understand your customers

You can only develop products and services that will be a big hit if you pay attention to the needs of your customers and prospects. One way to understand exactly what your customers want is through research and surveys. You should constantly invite them to give honest, brutal feedback.

Reviews and surveys are the best way to get into the minds of your customers. This makes it easier for you to develop products and services that are appropriate to the current demands of the market. Moreover, it helps you understand the area in which your company needs to improve.

2. Improving customer service

If you do not provide quality customer service, it will be difficult to satisfy your customers even if you have an excellent product or service. This aspect of the business is about taking extra steps to make them feel special. Let your customers know that they have value. If they have a problem, make sure you address them immediately. If they have questions, take the time to answer.

They should not feel that things are difficult for them if they raise specific issues. Social media is the best way to listen to and understand your customers. If they find customer service satisfactory, they may also recommend buying others from your business.

3. Establish loyalty

It takes time to encourage customers to come and buy what you offer. But just buying them is not enough. You need to promote loyalty. Considering there are other competitors who can offer them better, you want them to stay loyal to you. Don’t be satisfied just because you already have a lot of loyal customers.

They can easily be attracted to other options and they can leave you. Provide loyalty rewards. If there are discounts and discounts, let these most loyal customers be the first to know. You must make sure your customers know they are appreciated.

4. Focus on professional development

The success of your business also depends on the quality of the employees you hire. Building an effective team is the key to making sure your business grows.

One of the best ways to motivate hardworking employees is to give them a sense of purpose. They should not feel that they have to work just to work.

5. Understand your customers

Find ways to increase the sales of your existing customers. It's much cheaper than finding a new one. Even if you can't expand your product line, you can still sell more of your existing product or service to a client you already have. An easy way to do this is by volume discount.

6. Participate in networking events

Take the time to build your networks - it's not what you know but who you know. Networking allows you to build relationships with other people and encourage customers to refer to you through words.

7. Give back to your community

Creating brand awareness in your local community is a great way to attract new business. Consider participating in a sponsorship or community event to enhance your business profile.

We will see more points in our next tutorial.
