Usage
Add following XML namespace inside your XML layout file.
xmlns:app="http://schemas.android.com/apk/res-auto"
ColorPickerView in XML layout
We can use ColorPickerView
without any customized attributes.
This ColorPickerView
will be initialized with the default HSV color palette and default selector.
<com.skydoves.colorpickerview.ColorPickerView
android:id="@+id/colorPickerView"
android:layout_width="300dp"
android:layout_height="300dp" />
Attribute descriptions
We 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/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 invoked when tapped by a user or selected a position by a function.
colorPickerView.setColorListener(new ColorListener() {
@Override
public void onColorSelected(int color, boolean fromUser) {
LinearLayout linearLayout = findViewById(R.id.linearLayout);
linearLayout.setBackgroundColor(color);
}
});
ColorEnvelope
ColorEnvelope
is a wrapper class of color models for providing more variety of color models.
We can get HSV color value, Hex string code, ARGB value from the ColorEnvelope
.
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 it provides ColorEnvelope
as a parameter.
colorPickerView.setColorListener(new ColorEnvelopeListener() {
@Override
public void onColorSelected(ColorEnvelope envelope, boolean fromUser) {
linearLayout.setBackgroundColor(envelope.getColor());
textView.setText("#" + envelope.getHexCode());
}
});
Palette
If we do not set any customized palette, the default palette drawable is the ColorHsvPalette
.
We can move and select a point on the palette using a specific color using the below methods.
colorPickerView.selectByHsvColor(color);
colorPickerView.selectByHsvColorRes(R.color.colorPrimary);
We can change the default palette as a desired image drawable using the below method.
But if we change the palette using another drawable, we can not use the selectByHsvColor
method.
colorPickerView.setPaletteDrawable(drawable);
If we want to change back to the default palette, we can change it using the below method.
colorPickerView.setHsvPaletteDrawable();
ActionMode
ActionMode
is an option restrict to invoke the ColorListener
by user actions.
colorPickerView.setActionMode(ActionMode.LAST); // ColorListener will be invoked when the finger is released.
Debounce
Only emits color values to the listener if a particular timespan has passed without it emitting using debounceDuration
attribute. We can set the debounceDuration
on our xml layout file.
app:debounceDuration="150"
Or we can set it programmatically.
colorPickerView.setDebounceDuration(150);
Create using builder
This is how to create ColorPickerView
's instance using ColorPickerView.Builder
class.
ColorPickerView colorPickerView = new ColorPickerView.Builder(context)
.setColorListener(colorListener)
.setPreferenceName("MyColorPicker");
.setActionMode(ActionMode.LAST)
.setAlphaSlideBar(alphaSlideBar)
.setBrightnessSlideBar(brightnessSlideBar)
.setFlagView(new CustomFlag(context, R.layout.layout_flag))
.setPaletteDrawable(ContextCompat.getDrawable(context, R.drawable.palette))
.setSelectorDrawable(ContextCompat.getDrawable(context, R.drawable.selector))
.build();
Initial color
We can set an initial color and set positions of selector and slideBars based on the initial color.
This function will work only with a default HSV palette.
If we set preference name using the setPreferenceName
method, this function will work only once.
app:initialColor="@color/colorPrimary"
Or we 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
.
setLifecycleOwner()
method saves all of the states automatically when the lifecycleOwner is destroy.
colorPickerView.setLifecycleOwner(this);
Or we can save the states manually using the below method.
ColorPickerPreferenceManager.getInstance(this).saveColorPickerData(colorPickerView);
Manipulate and clear
We can manipulate and clear the saved states using ColorPickerPreferenceManager
.
ColorPickerPreferenceManager manager = ColorPickerPreferenceManager.getInstance(this);
manager.setColor("MyColorPicker", Color.RED); // manipulates the saved color data.
manager.setSelectorPosition("MyColorPicker", new Point(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 how to get a bitmap drawable from the gallery image and set it to the palette.
Declare below permission on your AndroidManifest.xml
file.
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
The below codes will start the Gallery and we can choose the desired image.
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, REQUEST_CODE_GALLERY);
In the onActivityResult
, we can get a bitmap drawable from the gallery and set it as the palette. And We can change the palette image of the ColorPickerView
using the setPaletteDrawable
method.
try {
final Uri imageUri = data.getData();
final InputStream imageStream = getContentResolver().openInputStream(imageUri);
final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
Drawable drawable = new BitmapDrawable(getResources(), selectedImage);
colorPickerView.setPaletteDrawable(drawable);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
AlphaSlideBar
AlphaSlideBar changes the transparency of the selected color.
AlphaSlideBar
in XML layout
<com.skydoves.colorpickerview.sliders.AlphaSlideBar
android:id="@+id/alphaSlideBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:selector_AlphaSlideBar="@drawable/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.
We can attach and connect the AlphaSlideBar
to our ColorPickerView
using attachAlphaSlider
method.
AlphaSlideBar alphaSlideBar = findViewById(R.id.alphaSlideBar);
colorPickerView.attachAlphaSlider(alphaSlideBar);
We can make it vertically using the below attributes.
android:layout_width="280dp" // width must set a specific width size.
android:layout_height="wrap_content"
android:rotation="90"
BrightnessSlideBar
BrightnessSlideBar changes the brightness of the selected color.
BrightnessSlideBar
in XML layout
<com.skydoves.colorpickerview.sliders.BrightnessSlideBar
android:id="@+id/brightnessSlide"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:selector_BrightnessSlider="@drawable/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.
We can attach and connect the BrightnessSlideBar
to our ColorPickerView
using attachBrightnessSlider
method.
BrightnessSlideBar brightnessSlideBar = findViewById(R.id.brightnessSlide);
colorPickerView.attachBrightnessSlider(brightnessSlideBar);
We can make it vertically using the below attributes.
android:layout_width="280dp" // width must set a specific width size.
android:layout_height="wrap_content"
android:rotation="90"
ColorPickerDialog
ColorPickerDialog
can be used just like an AlertDialog and it provides colors by tapping from any drawable.
new ColorPickerDialog.Builder(this)
.setTitle("ColorPicker Dialog")
.setPreferenceName("MyColorPickerDialog")
.setPositiveButton(getString(R.string.confirm),
new ColorEnvelopeListener() {
@Override
public void onColorSelected(ColorEnvelope envelope, boolean fromUser) {
setLayoutColor(envelope);
}
})
.setNegativeButton(getString(R.string.cancel),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
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();
we can get an instance of ColorPickerView
from the ColorPickerView.Builder
and we can customize it.
ColorPickerView colorPickerView = builder.getColorPickerView();
colorPickerView.setFlagView(new CustomFlag(this, R.layout.layout_flag)); // sets a custom flagView
builder.show(); // shows the dialog
FlagView
We can implement showing a FlagView
above and below on the selector.
This library provides BubbleFlagView
by default as we can see the previews.
Here is the example code for implementing it.
BubbleFlag bubbleFlag = new BubbleFlag(this);
bubbleFlag.setFlagMode(FlagMode.FADE);
colorPickerView.setFlagView(bubbleFlag);
We can also fully customize the FlagView
like below.
First, We need a customized layout like below.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns: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">
<LinearLayout
android:id="@+id/flag_color_layout"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginTop="6dp"
android:layout_marginLeft="5dp"
android:orientation="vertical"/>
<TextView
android: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>
Second, we need to create a class that extends FlagView
. Here is an example code.
public class CustomFlag extends FlagView {
private TextView textView;
private AlphaTileView alphaTileView;
public CustomFlag(Context context, int layout) {
super(context, layout);
textView = findViewById(R.id.flag_color_code);
alphaTileView = findViewById(R.id.flag_color_layout);
}
@Override
public void onRefresh(ColorEnvelope colorEnvelope) {
textView.setText("#" + colorEnvelope.getHexCode());
alphaTileView.setPaintColor(colorEnvelope.getColor());
}
}
And last, set the FlagView
to the ColorPickerView
using the setFlagView
method.
colorPickerView.setFlagView(new CustomFlag(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
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.AlphaTileView
android:id="@+id/alphaTileView"
android:layout_width="55dp"
android:layout_height="55dp"
app:tileSize="20" // the size of the repeating tile
app:tileEvenColor="@color/tile_even" // the color of even tiles
app:tileOddColor="@color/tile_odd"/> // the color of odd tiles
