Download

Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.ChaosLeong:PinView:1.4.3'
	}
	dependencies {
		implementation("com.github.ChaosLeong:PinView:1.4.3")
	}
	<dependency>
	    <groupId>com.github.ChaosLeong</groupId>
	    <artifactId>PinView</artifactId>
	    <version>1.4.3</version>
	</dependency>

                            
    libraryDependencies += "com.github.ChaosLeong" % "PinView" % "1.4.3"
        
        

                            
    :dependencies [[com.github.ChaosLeong/PinView "1.4.3"]]

Dependency

~~JCenter~~(Deprecated)

repositories {
    maven {
        jcenter()
    }
}

dependencies {
   implementation 'com.chaos.view:pinview:1.4.4'
}

MavenCentral

repositories {
    maven {
        mavenCentral()
    }
}

dependencies {
   implementation 'io.github.chaosleung:pinview:1.4.4'
}

Note that MavenCentral uses io.github.chaosleung as the group id

Usage

PinView inherits from EditText, which means you can use all the APIs from EditText.

Step 1:

Add PinView in your layout.

XML

<com.chaos.view.PinView
    android:id="@+id/firstPinView"
    style="@style/PinWidget.PinView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:cursorVisible="true"
    android:hint="Hint."
    android:inputType="text"
    android:itemBackground="@mipmap/ic_launcher"
    android:padding="@dimen/common_padding"
    android:textColor="@color/text_colors"
    android:textSize="18sp"
    android:textStyle="bold"
    app:cursorColor="@color/line_selected"
    app:cursorWidth="2dp"
    app:hideLineWhenFilled="true"
    app:itemCount="5"
    app:itemHeight="48dp"
    app:itemRadius="4dp"
    app:itemSpacing="0dp"
    app:itemWidth="48dp"
    app:lineColor="@color/line_colors"
    app:lineWidth="2dp"
    app:viewType="rectangle" />

Java

final PinView pinView = findViewById(R.id.secondPinView);
pinView.setTextColor(
        ResourcesCompat.getColor(getResources(), R.color.colorAccent, getTheme()));
pinView.setTextColor(
        ResourcesCompat.getColorStateList(getResources(), R.color.text_colors, getTheme()));
pinView.setLineColor(
        ResourcesCompat.getColor(getResources(), R.color.colorPrimary, getTheme()));
pinView.setLineColor(
        ResourcesCompat.getColorStateList(getResources(), R.color.line_colors, getTheme()));
pinView.setItemCount(4);
pinView.setItemHeight(getResources().getDimensionPixelSize(R.dimen.pv_pin_view_item_size));
pinView.setItemWidth(getResources().getDimensionPixelSize(R.dimen.pv_pin_view_item_size));
pinView.setItemRadius(getResources().getDimensionPixelSize(R.dimen.pv_pin_view_item_radius));
pinView.setItemSpacing(getResources().getDimensionPixelSize(R.dimen.pv_pin_view_item_spacing));
pinView.setLineWidth(getResources().getDimensionPixelSize(R.dimen.pv_pin_view_item_line_width));
pinView.setAnimationEnable(true);// start animation when adding text
pinView.setCursorVisible(false);
pinView.setCursorColor(
        ResourcesCompat.getColor(getResources(), R.color.line_selected, getTheme()));
pinView.setCursorWidth(getResources().getDimensionPixelSize(R.dimen.pv_pin_view_cursor_width));
pinView.addTextChangedListener(new TextWatcher() {...});
pinView.setItemBackgroundColor(Color.BLACK);
pinView.setItemBackground(getResources().getDrawable(R.drawable.item_background));
pinView.setItemBackgroundResources(R.drawable.item_background);
pinView.setHideLineWhenFilled(false);
pinView.setPasswordHidden(false);
pinView.setTransformationMethod(new PasswordTransformationMethod());

Step 2:

Specifies pinViewStyle in your theme,

<style name="AppTheme" parent="Theme.AppCompat.Light">
    ...
    <item name="pinViewStyle">@style/PinWidget.PinView</item>
</style>

or use the PinWidget.PinView style.

<com.chaos.view.PinView
    android:id="@+id/pinView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    style="@style/PinWidget.PinView" />

Step 3 (Optional):

To highlight current item, use 'selected' state, in other words,

add android:state_selected="true" to app:lineColor

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Use for the item to be input, set the value as the default to disable it -->
    <item android:color="@color/line_selected" android:state_selected="true" />
    <item android:color="@color/line_focused" android:state_focused="true" />
    <item android:color="@color/line_default" />
</selector>

or add android:cursorVisible="true".
