How to use Android sequence layout?

Before getting into android sequence layout, we should know what is sequence layout in android. Sequence layout contains a sequence of steps with the progress bar. According to sequence, it follows an animated progress bar.

This example demonstrates How to use Android sequence layout.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Open build.gradle(app) and add design support library dependency.

apply plugin: 'com.android.application'
android {
   compileSdkVersion 28
   defaultConfig {
      applicationId "com.example.andy.myapplication"
      minSdkVersion 19
      targetSdkVersion 28
      versionCode 1
      versionName "1.0"
      testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
   }
   buildTypes {
      release {
         minifyEnabled false
         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      }
   }
}
dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   implementation 'com.android.support:appcompat-v7:28.0.0'
   implementation 'com.google.code.gson:gson:2.8.5'
   implementation 'com.android.support.constraint:constraint-layout:1.1.3'
   testImplementation 'junit:junit:4.12'
   implementation 'com.github.transferwise:sequence-layout:1.0.7'
   androidTestImplementation 'com.android.support.test:runner:1.0.2'
   androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

Step 3 − Open build.gradle(project) and add design support library dependency.

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
   repositories {
      google()
      jcenter()
   }
   dependencies {
      classpath 'com.android.tools.build:gradle:3.2.1'
      // NOTE: Do not place your application dependencies here; they belong
      // in the individual module build.gradle files
   }
}
allprojects {
   repositories {
      google()
      jcenter()
      maven { url "https://jitpack.io" }
   }
}
task clean(type: Delete) {
   delete rootProject.buildDir
}

Step 4 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<com.transferwise.sequencelayout.SequenceLayout
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto">
   <com.transferwise.sequencelayout.SequenceStep
      android:id="@+id/first"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:subtitle="Lorem Ipsum is simply dummy text of the printing and typesetting industry. 
         Lorem Ipsum has been the industry's standard dummy text ever since the 1500s."
      app:anchor="30 Nov"
      app:title="First step"/>
   <com.transferwise.sequencelayout.SequenceStep
      android:id="@+id/second"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:subtitle="Lorem Ipsum is simply dummy text of the printing and typesetting industry. 
         Lorem Ipsum has been the industry's standard dummy text ever since the 1500s."
      app:title="Second step"/>
   <com.transferwise.sequencelayout.SequenceStep
      android:id="@+id/third"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:anchor="Today"
      app:title="Third step"
      app:subtitle="Lorem Ipsum is simply dummy text of the printing and typesetting industry. 
         Lorem Ipsum has been the industry's standard dummy text ever since the 1500s" />
</com.transferwise.sequencelayout.SequenceLayout>

In the above, we have declared sequence layout as a parent layout and added sequence steps as individual steps. each step contacts anchor view, title, and subtitle.

Step 5 − Add the following code to src/MainActivity.java

package com.example.andy.myapplication;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Toast;
import com.transferwise.sequencelayout.SequenceStep;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
   SequenceStep sequenceStep,sequenceStep2,sequenceStep3;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      sequenceStep=findViewById(R.id.first);
      sequenceStep2=findViewById(R.id.second);
      sequenceStep3=findViewById(R.id.third);
      sequenceStep2.setActive(true);
      sequenceStep.setOnClickListener(this);
      sequenceStep2.setOnClickListener(this);
      sequenceStep3.setOnClickListener(this);
   }
   @Override
   public void onClick(View v) {
      switch (v.getId()) {
         case R.id.first:
            Toast.makeText(MainActivity.this,"This is first step",Toast.LENGTH_LONG).show();
            break;
         case R.id.second:
            Toast.makeText(MainActivity.this,"This is second step",Toast.LENGTH_LONG).show();
            break;
         case R.id.third:
            Toast.makeText(MainActivity.this,"This is Third step",Toast.LENGTH_LONG).show();
            break;
      }
   }
}

In the above code, we have declared sequence steps and given on Click Listener. To active steps use the following code.

sequenceStep2.setActive(true);

In the above code, we have declared sequence2 is active means progress bar going to show until sequence step 2.

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from an android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −

In the above example, as we have declared active mode, it has shown a progress bar.
