State ProgressBar in Android

A State ProgressBar is a unique kind of progress bar which reflects the progression through a series of states or steps. Rather than the conventional linear progress bar, this shows steps (or states) as users proceed through a sequence.

To implement a State ProgressBar in Android, you can use the StateProgressBar library available on GitHub. Here's a guide to help you get started:

1. Add Dependency:

Add the following dependency to your app-level build.gradle file:

implementation 'com.kofigyan.stateprogressbar:stateprogressbar:1.0.0' // Check for the latest version on GitHub

2. XML Layout:

Include the StateProgressBar in your XML layout:

activity_main.xml:

<com.kofigyan.stateprogressbar.StateProgressBar
    android:id="@+id/stateProgressBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="50dp"/>

3. Configure in Kotlin:

MainActivity.kt:

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import com.kofigyan.stateprogressbar.StateProgressBar

class MainActivity : AppCompatActivity() {

    private lateinit var stateProgressBar: StateProgressBar

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        stateProgressBar = findViewById(R.id.stateProgressBar)

        // Define the steps (or states)
        val steps = arrayOf("Step 1", "Step 2", "Step 3", "Step 4")
        stateProgressBar.setStateDescriptionData(steps)

        // To go to the next step
        // stateProgressBar.setCurrentStateNumber(StateProgressBar.StateNumber.TWO)
        // ... and so on.
    }
}

4. Customization:

StateProgressBar provides a range of attributes to customize its appearance and behavior. Here are some of them:

  • spb_stateNumber: Number of the current state (from ONE to TEN).
  • spb_maxStateNumber: Maximum state number.
  • spb_stateSize: Size of a state (width & height).
  • spb_stateLineWidth: Width of the line between states.
  • spb_stateNumberTextSize: Text size of the state number.
  • spb_stateDescriptionSize: Text size of the state description.
  • spb_currentStateDescriptionColor: Text color of the current state's description.
  • spb_stateDescriptionColor: Text color of state descriptions.
  • spb_currentStateNumberColor: Color of the current state number.
  • spb_stateNumberColor: Color of the state number.
  • spb_currentStateColor: Color of the current state.
  • spb_stateColor: Color of states.

You can set these attributes in the XML layout or programmatically in your Kotlin code.

5. Change States:

To move between steps (or states) programmatically, you can use:

stateProgressBar.setCurrentStateNumber(StateProgressBar.StateNumber.TWO)

This approach helps create a visual representation of progression through a series of steps or states, offering a better UX for scenarios such as multi-step user registrations, order processes, or tutorials.

  1. Implementing State ProgressBar in Android example code:

    • Description: Demonstrates the basic implementation of a State ProgressBar in Android.

    • Example Code (XML/Java):

      <com.example.StateProgressBar
    android:id="@+id/stateProgressBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

      StateProgressBar stateProgressBar = findViewById(R.id.stateProgressBar);
// Set states and current state

  2. Customizing State ProgressBar appearance in Android:

    • Description: Customizes the appearance of the State ProgressBar, such as color, size, and style.

    • Example Code (XML/Java):

      <com.example.StateProgressBar
    android:id="@+id/customProgressBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:spb_stateSize="20dp"
    app:spb_stateTextColor="#FF4081"
    app:spb_stateBackgroundColor="#E0E0E0"/>

      StateProgressBar customProgressBar = findViewById(R.id.customProgressBar);
// Apply custom styles programmatically if needed

  3. State ProgressBar with multiple states in Android:

    • Description: Sets up the State ProgressBar with multiple states to represent a sequence of steps.
    • Example Code (Java):
      StateProgressBar multiStateProgressBar = findViewById(R.id.multiStateProgressBar);
multiStateProgressBar.setStateDescriptionData(states);

  4. Handling progress updates in State ProgressBar Android:

    • Description: Manages progress updates in the State ProgressBar dynamically.
    • Example Code (Java):
      StateProgressBar progressUpdateProgressBar = findViewById(R.id.progressUpdateProgressBar);
progressUpdateProgressBar.setCurrentStateNumber(StateNumber.FOUR);

  5. State ProgressBar with percentage display in Android:

    • Description: Displays percentage along with state in the State ProgressBar.
    • Example Code (Java):
      StateProgressBar percentageProgressBar = findViewById(R.id.percentageProgressBar);
percentageProgressBar.setStateDescriptionData(statesWithPercentage);

  6. Dynamic state transitions in Android State ProgressBar:

    • Description: Dynamically changes state transitions based on user actions or events.
    • Example Code (Java):
      StateProgressBar dynamicTransitionProgressBar = findViewById(R.id.dynamicTransitionProgressBar);
dynamicTransitionProgressBar.setStateDescriptionData(states);
// Dynamically update state transitions

  7. Animating State ProgressBar changes in Android:

    • Description: Adds animations to State ProgressBar changes for a visually appealing effect.
    • Example Code (Java):
      StateProgressBar animatedProgressBar = findViewById(R.id.animatedProgressBar);
animatedProgressBar.setStateDescriptionData(states);
// Apply animation on state changes

  8. State ProgressBar with different colors for each state in Android:

    • Description: Assigns distinct colors to each state in the State ProgressBar.
    • Example Code (Java):
      StateProgressBar coloredProgressBar = findViewById(R.id.coloredProgressBar);
coloredProgressBar.setStateDescriptionData(statesWithColors);

  9. State ProgressBar with icon or image in Android:

    • Description: Incorporates icons or images into the State ProgressBar for visual representation.
    • Example Code (Java):
      StateProgressBar iconProgressBar = findViewById(R.id.iconProgressBar);
iconProgressBar.setStateDescriptionData(statesWithIcons);

  10. State ProgressBar with Kotlin in Android:

    • Description: Translates the State ProgressBar examples to Kotlin for a concise and expressive syntax.

    • Example Code (XML/Kotlin):

      <com.example.StateProgressBar
    android:id="@+id/kotlinProgressBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

      val kotlinProgressBar: StateProgressBar = findViewById(R.id.kotlinProgressBar)

accessibleProgressBar.setContentDescription(getString(R.string.progress_bar_content_description));

  12. Circular State ProgressBar in Android:

    • Description: Configures a circular variant of the State ProgressBar.

    • Example Code (XML/Java):

      <com.example.CircularStateProgressBar
