Color Picker Dialog(Ambilwarna)

 

In this tutorial, we will use a 3rd party library called AmbilWarna to implement a color picker into our app. We will then use the picked color and set the background of our Activity to it.

In build.gradle file add these dependency:-

implementation 'com.github.yukuku:ambilwarna:2.0.1'

In MainActivity.java class file add these lines of codes:-

package com.deftskill.colorpickerexample;

import androidx.appcompat.app.AppCompatActivity;
import androidx.constraintlayout.widget.ConstraintLayout;
import androidx.core.content.ContextCompat;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;

import yuku.ambilwarna.AmbilWarnaDialog;

public class MainActivity extends AppCompatActivity {
    ConstraintLayout mLayout;
    int mDefaultColor;
    Button mButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mLayout = (ConstraintLayout) findViewById(R.id.layout);
        mDefaultColor = ContextCompat.getColor(MainActivity.this, R.color.colorPrimary);
        mButton = (Button) findViewById(R.id.button);
        mButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                openColorPicker();
            }
        });
    }
    public void openColorPicker() {
        AmbilWarnaDialog colorPicker = new AmbilWarnaDialog(this, mDefaultColor, new AmbilWarnaDialog.OnAmbilWarnaListener() {
            @Override
            public void onCancel(AmbilWarnaDialog dialog) {
            }
            @Override
            public void onOk(AmbilWarnaDialog dialog, int color) {
                mDefaultColor = color;
                mLayout.setBackgroundColor(mDefaultColor);
            }
        });
        colorPicker.show();
    }
}

In activity_main.xml file add these lines of codes:-

<?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:id="@+id/layout"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="open color picker"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>
After adding these lines of codes run this application.
