DoubleLinkedListEditText Library
This is a library to create an EditText based on the Doubly Linked List data structure so that the user can enter codes.
Install
Step 1. Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
implementation 'com.github.layonmartins:DoubleLinkedListEditText:1.1.1'
}
Usage
You can add the custom DoubleLinkedListEditText in your layout view by add in xml:
xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<com.layon.doublelinkedlistlibrary.DoubleLinkedListEditText
android:id="@+id/doubleLinkedListEditText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="100dp"
android:layout_marginTop="100dp"
android:visibility="visible"
android:gravity="center"
android:orientation="horizontal"
app:size_elements="4"
app:element_layout_weight="80dp"
app:element_layout_height="80dp"
app:margin_between_elements="10dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
com.layon.doublelinkedlistlibrary.DoubleLinkedListEditText>
androidx.constraintlayout.widget.ConstraintLayout>
Use this xml atributes to config your codes:
| Property | Value / Type | Goal |
|---|---|---|
| app:size_elements | int | the number of input code elements |
| app:element_layout_weight | dp | layout_weight of each element |
| app:element_layout_height | dp | layout_height of each element |
| app:margin_between_elements | dp | the margin between of each element |
And in your Activity/Fragment layout you can use a CheckCodeCallbalck to listener the finally user inputs (Kotlin):
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import com.layon.doublelinkedlistlibrary.DoubleLinkedListEditText
class MainActivity : AppCompatActivity() {
var TAG = "layon.f - MainActivity"
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val doubleLinkedListEditText: DoubleLinkedListEditText = findViewById(R.id.doubleLinkedListEditText)
doubleLinkedListEditText.setCheckCodeCallback( object :
com.layon.doublelinkedlistlibrary.CheckCodeCallback {
override fun checkCode(code: String) {
if (code == "1234"){
Log.d(TAG, "checkCode success")
doubleLinkedListEditText.setSuccessBackground()
//do whatever you want
} else {
Log.d(TAG, "checkCode fail")
doubleLinkedListEditText.setErrorBackground()
}
}
})
}
}
