Usage

Add following XML namespace inside your XML layout file.

xmlns:app="http://schemas.android.com/apk/res-auto"

ColorPickerView in XML layout

You can simply use ColorPickerView by defining it on your XML files. This ColorPickerView will be initialized with the default HSV color palette and the default selector.

<com.skydoves.colorpickerview.ColorPickerViewandroid:id="@+id/colorPickerView"android:layout_width="300dp"android:layout_height="300dp"/>

Attributes

You can customize the palette image and selector or various options using the below attributes:

app:palette="@drawable/palette"// sets a custom palette image.app:selector="@drawable/colorpickerview_wheel"// sets a custom selector image.app:selector_size="32dp"// sets a width & height size of the selector.app:alpha_selector="0.8"// sets an alpha of thr selector.app:alpha_flag="0.8"// sets an alpha of the flag.app:actionMode="last"// sets action mode 'always' or 'last'.// set an initial position of the selector using a specific color. This attribute will work with only a default HSV palette.app:initialColor="@color/colorPrimary"app:preferenceName="MyColorPicker"// sets a preference name.app:debounceDuration="200"// sets a debounce duration of the invoking color listener.

ColorListener

ColorListener is triggered when a user taps the ColorPickerView or when a position is selected using a function.

colorPickerView.setColorListener(newColorListener(){@OverridepublicvoidonColorSelected(intcolor, booleanfromUser){LinearLayoutlinearLayout = findViewById(R.id.linearLayout); linearLayout.setBackgroundColor(color)} });

ColorEnvelope

ColorEnvelope is a versatile wrapper class for color models, offering a wide range of color-related data. It provides access to HSV color values, Hex string codes, and ARGB values.

colorEnvelope.getColor() // returns a integer color.colorEnvelope.getHexCode() // returns a hex code string.colorEnvelope.getArgb() // returns a argb integer array.

ColorEnvelope Listener

ColorEnvelopeListener extends ColorListener and offers ColorEnvelope as a parameter, granting access to a variety of color values.

colorPickerView.setColorListener(newColorEnvelopeListener(){@OverridepublicvoidonColorSelected(ColorEnvelopeenvelope, booleanfromUser){linearLayout.setBackgroundColor(envelope.getColor()); textView.setText("#" + envelope.getHexCode())} });

Palette

If you do not set any custom palette, the default palette will be the ColorHsvPalette.
You can manually select a specific point for the selector by specifying a particular color value using the following methods:

colorPickerView.selectByHsvColor(color); colorPickerView.selectByHsvColorRes(R.color.colorPrimary);

You can change the default palette as a desired image drawable using the method below:

colorPickerView.setPaletteDrawable(drawable);

If you wish to revert to the default HSV palette, you can do so using the method below:

colorPickerView.setHsvPaletteDrawable();

ActionMode

ActionMode is an option that restricts the invocation of the ColorListener based on user actions.

colorPickerView.setActionMode(ActionMode.LAST); // ColorListener will be invoked when the finger is released.

Debounce

If you want to emit color values to the listener with a particular delay, you can utilize debounceDuration attribute in your XML layout file:

app:debounceDuration="150"

Or you can set it programmatically.

colorPickerView.setDebounceDuration(150);

Create using builder

You can create an instance of ColorPickerView using ColorPickerView.Builder class like the example below:

ColorPickerViewcolorPickerView = newColorPickerView.Builder(context) .setColorListener(colorListener) .setPreferenceName("MyColorPicker"); .setActionMode(ActionMode.LAST) .setAlphaSlideBar(alphaSlideBar) .setBrightnessSlideBar(brightnessSlideBar) .setFlagView(newCustomFlag(context, R.layout.layout_flag)) .setPaletteDrawable(ContextCompat.getDrawable(context, R.drawable.palette)) .setSelectorDrawable(ContextCompat.getDrawable(context, R.drawable.selector)) .build();

Initial color

You can define an initial color and position the selector and slide bars based on that initial color. Please note that this function is compatible only with the default HSV palette. Additionally, if you set a preference name using the setPreferenceName method, this function will work only once.

app:initialColor="@color/colorPrimary"

Or you can use this method programmatically.

.setInitialColor(color); .setInitialColorRes(R.color.colorPrimary);

Restore and save

This is how to restore the state of ColorPickerView.
setPreferenceName() method restores all of the saved states (selector, color) automatically.

colorPickerView.setPreferenceName("MyColorPicker");

This is how to save the states of ColorPickerView.
The setLifecycleOwner() method saves all of the states automatically when the lifecycleOwner is destroy.

colorPickerView.setLifecycleOwner(this);

Or you can save the states manually using the method below:

ColorPickerPreferenceManager.getInstance(this).saveColorPickerData(colorPickerView);

Manipulate and clear

You can manipulate and clear the saved states using ColorPickerPreferenceManager.

ColorPickerPreferenceManagermanager = ColorPickerPreferenceManager.getInstance(this); manager.setColor("MyColorPicker", Color.RED); // manipulates the saved color data.manager.setSelectorPosition("MyColorPicker", newPoint(120, 120)); // manipulates the saved selector's position data.manager.clearSavedAllData(); // clears all of the states.manager.clearSavedColor("MyColorPicker"); // clears only saved color data. manager.restoreColorPickerData(colorPickerView); // restores the saved states manually.

Palette from Gallery

Here is an example of how to get a bitmap drawable from the gallery image and set it to the palette.

Declare the permission below on your AndroidManifest.xml file:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

The codes below will start the Gallery and you can choose any desired images:

IntentphotoPickerIntent = newIntent(Intent.ACTION_PICK); photoPickerIntent.setType("image/*"); startActivityForResult(photoPickerIntent, REQUEST_CODE_GALLERY);

In the onActivityResult, you can get a bitmap drawable from the gallery and set it as the palette. You can also change the palette image of the ColorPickerView using the setPaletteDrawable method.

try{finalUriimageUri = data.getData(); finalInputStreamimageStream = getContentResolver().openInputStream(imageUri); finalBitmapselectedImage = BitmapFactory.decodeStream(imageStream); Drawabledrawable = newBitmapDrawable(getResources(), selectedImage); colorPickerView.setPaletteDrawable(drawable)} catch (FileNotFoundExceptione){e.printStackTrace()}

AlphaSlideBar

AlphaSlideBar adjusts the transparency value of the selected color.

AlphaSlideBar in XML layout

<com.skydoves.colorpickerview.sliders.AlphaSlideBarandroid:id="@+id/alphaSlideBar"android:layout_width="match_parent"android:layout_height="wrap_content"app:selector_AlphaSlideBar="@drawable/colorpickerview_wheel"// sets a customized selector drawable.app:borderColor_AlphaSlideBar="@android:color/darker_gray"// sets a color of the border.app:borderSize_AlphaSlideBar="5"/> // sets a size of the border.

You can attach and connect the AlphaSlideBar to your ColorPickerView using the attachAlphaSlider method.

AlphaSlideBaralphaSlideBar = findViewById(R.id.alphaSlideBar); colorPickerView.attachAlphaSlider(alphaSlideBar);

If you want to implement a vertical style of slides, you can achieve it with the rotation attributes.

android:layout_width="280dp"// width must set a specific width size.android:layout_height="wrap_content"android:rotation="90"

BrightnessSlideBar

BrightnessSlideBar adjusts the brightness of the selected color.

BrightnessSlideBar in XML layout

<com.skydoves.colorpickerview.sliders.BrightnessSlideBarandroid:id="@+id/brightnessSlide"android:layout_width="match_parent"android:layout_height="wrap_content"app:selector_BrightnessSlider="@drawable/colorpickerview_wheel"// sets a customized selector drawable.app:borderColor_BrightnessSlider="@android:color/darker_gray"// sets a color of the border.app:borderSize_BrightnessSlider="5"/> // sets a size of the border.

You can attach and connect the BrightnessSlideBar to your ColorPickerView using attachBrightnessSlider method.

BrightnessSlideBarbrightnessSlideBar = findViewById(R.id.brightnessSlide); colorPickerView.attachBrightnessSlider(brightnessSlideBar);

If you want to implement a vertical style of slides, you can achieve it with the rotation attributes.

android:layout_width="280dp"// width must set a specific width size.android:layout_height="wrap_content"android:rotation="90"

ColorPickerDialog

dialog0dialog1

ColorPickerDialog can be used just like an AlertDialog and it provides colors by tapping from any drawable.

newColorPickerDialog.Builder(this) .setTitle("ColorPicker Dialog") .setPreferenceName("MyColorPickerDialog") .setPositiveButton(getString(R.string.confirm), newColorEnvelopeListener(){@OverridepublicvoidonColorSelected(ColorEnvelopeenvelope, booleanfromUser){setLayoutColor(envelope)} }) .setNegativeButton(getString(R.string.cancel), newDialogInterface.OnClickListener(){@OverridepublicvoidonClick(DialogInterfacedialogInterface, inti){dialogInterface.dismiss()} }) .attachAlphaSlideBar(true) // the default value is true. .attachBrightnessSlideBar(true) // the default value is true. .setBottomSpace(12) // set a bottom space between the last slidebar and buttons. .show();

You can get an instance of ColorPickerView from the ColorPickerView.Builder and customize it by your preferences.

ColorPickerViewcolorPickerView = builder.getColorPickerView(); colorPickerView.setFlagView(newCustomFlag(this, R.layout.layout_flag)); // sets a custom flagViewbuilder.show(); // shows the dialog

FlagView

You can implement displaying FlagView over the selector.
This library provides BubbleFlagView by default as you can see in the previews.
Here is an example code for displaying a bubble flag view, which indicates what color value was selected.

BubbleFlagbubbleFlag = newBubbleFlag(this); bubbleFlag.setFlagMode(FlagMode.FADE); colorPickerView.setFlagView(bubbleFlag);

You can also fully customize the FlagView like the example below:

flag0flag1

First, create a custom XML layout like the example below:

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="100dp"android:layout_height="40dp"android:background="@drawable/flag"android:orientation="horizontal"><com.skydoves.colorpickerview.AlphaTileViewandroid:id="@+id/flag_color_layout"android:layout_width="20dp"android:layout_height="20dp"android:layout_marginTop="6dp"android:layout_marginLeft="5dp"android:orientation="vertical"/><TextViewandroid:id="@+id/flag_color_code"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="6dp"android:layout_marginLeft="10dp"android:layout_marginRight="5dp"android:textSize="14dp"android:textColor="@android:color/white"android:maxLines="1"android:ellipsize="end"android:textAppearance="?android:attr/textAppearanceSmall"tools:text="#ffffff"/></LinearLayout>

Next, you should create a class that extends FlagView:

publicclassCustomFlagextendsFlagView{privateTextViewtextView; privateAlphaTileViewalphaTileView; publicCustomFlag(Contextcontext, intlayout){super(context, layout); textView = findViewById(R.id.flag_color_code); alphaTileView = findViewById(R.id.flag_color_layout)} @OverridepublicvoidonRefresh(ColorEnvelopecolorEnvelope){textView.setText("#" + colorEnvelope.getHexCode()); alphaTileView.setPaintColor(colorEnvelope.getColor())} }

As you can see in the above code, you can observe and update the layout inside the onRefresh method. Lastly, set the FlagView to the ColorPickerView using the setFlagView method:

colorPickerView.setFlagView(newCustomFlag(this, R.layout.layout_flag));

FlagMode

FlagMode is an option to decides the visibility action of the FlagView.

colorPickerView.setFlagMode(FlagMode.ALWAYS); // showing always by tapping and dragging.colorPickerView.setFlagMode(FlagMode.LAST); // showing only when finger released.

AlphaTileView

alphatileview
AlphaTileView visualizes ARGB colors over the view.
If we need to represent ARGB colors on the general view, it will not be showing accurately. Because a color will be mixed with the parent view's background color. so if we need to represent ARGB colors accurately, we can use the AlphaTileView.

<com.skydoves.colorpickerview.AlphaTileViewandroid:id="@+id/alphaTileView"android:layout_width="55dp"android:layout_height="55dp"app:tileSize="20"// the size of the repeating tileapp:tileEvenColor="@color/tile_even"// the color of even tilesapp:tileOddColor="@color/tile_odd"/> // the color of odd tiles
