A library that lets you implement ColorPickerView, ColorPickerDialog, ColorPickerPreference.
Could get HSV color, RGB values, Html color code from your gallery pictures or custom images just by touching.
## Including in your project
[](https://search.maven.org/search?q=g:%22com.github.skydoves%22%20AND%20a:%22colorpickerpreference%22)
[](https://jitpack.io/#skydoves/ColorPickerPreference)
#### Gradle
Add below codes to your **root** `build.gradle` file (not your module build.gradle file).
```gradle
allprojects {
repositories {
mavenCentral()
}
}
```
And add a dependency code to your **module**'s `build.gradle` file.
```gradle
dependencies {
implementation "com.github.skydoves:colorpickerpreference:2.0.6"
}
```
## Usage
Add following XML namespace inside your XML layout file.
```gradle
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.
```gradle
```
### Attribute descriptions
We can customize the palette image and selector or various options using the below attributes.
```gradle
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'.
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.
```java
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`.
```java
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.
```java
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.
```java
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.
```java
colorPickerView.setPaletteDrawable(drawable);
```
If we want to change back to the default palette, we can change it using the below method.
```java
colorPickerView.setHsvPaletteDrawable();
```
### ActionMode
`ActionMode` is an option restrict to invoke the `ColorListener` by user actions.
```java
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.
```xml
app:debounceDuration="150"
```
Or we can set it programmatically.
```java
colorPickerView.setDebounceDuration(150);
```
### Create using builder
This is how to create `ColorPickerView`'s instance using `ColorPickerView.Builder` class.
```java
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();
```
### Restore and save
This is how to restore the state of `ColorPickerView`.
`setPreferenceName()` method restores all of the saved states (selector, color) automatically.
```java
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.
```java
colorPickerView.setLifecycleOwner(this);
```
Or we can save the states manually using the below method.
```java
ColorPickerPreferenceManager.getInstance(this).saveColorPickerData(colorPickerView);
```
### Manipulate and clear
We can manipulate and clear the saved states using `ColorPickerPreferenceManager`.
```java
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.
```gradle
```
The below codes will start the Gallery and we can choose the desired image.
```java
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.
```java
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();
}
```
### ColorPickerPreference
ColorPickerPreference is used in PreferenceScreen and shows ColorPickerDialog if be clicked.
```xml
`AlphaSlideBar` in XML layout
```gradle
// sets a size of the border.
```
We can attach and connect the `AlphaSlideBar` to our `ColorPickerView` using `attachAlphaSlider` method.
```java
AlphaSlideBar alphaSlideBar = findViewById(R.id.alphaSlideBar);
colorPickerView.attachAlphaSlider(alphaSlideBar);
```
We can make it vertically using the below attributes.
```gradle
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
```gradle
// sets a size of the border.
```
We can attach and connect the `BrightnessSlideBar` to our `ColorPickerView` using `attachBrightnessSlider` method.
```java
BrightnessSlideBar brightnessSlideBar = findViewById(R.id.brightnessSlide);
colorPickerView.attachBrightnessSlider(brightnessSlideBar);
```
We can make it vertically using the below attributes.
```gradle
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.
```java
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.
```java
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](https://github.com/skydoves/ColorPickerView#colorpickerview).
Here is the example code for implementing it.
```java
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.
```gradle
```
Second, we need to create a class that extends `FlagView`. Here is an example code.
```java
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.
```java
colorPickerView.setFlagView(new CustomFlag(this, R.layout.layout_flag));
```
### FlagMode
`FlagMode` is an option to decides the visibility action of the `FlagView`.
```java
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`.
```gradle
// the color of odd tiles
```
