## Usage
Add following XML namespace inside your XML layout file.
```gradle
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.
```gradle
```
### Attributes
You 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/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.
```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 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.
```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 offers `ColorEnvelope` as a parameter, granting access to a variety of color values.
```java
colorPickerView.setColorListener(new ColorEnvelopeListener() {
@Override
public void onColorSelected(ColorEnvelope envelope, boolean fromUser) {
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:
```java
colorPickerView.selectByHsvColor(color);
colorPickerView.selectByHsvColorRes(R.color.colorPrimary);
```
You can change the default palette as a desired image drawable using the method below:
```java
colorPickerView.setPaletteDrawable(drawable);
```
If you wish to revert to the default HSV palette, you can do so using the method below:
```java
colorPickerView.setHsvPaletteDrawable();
```
### ActionMode
`ActionMode` is an option that restricts the invocation of the ColorListener based on user actions.
```java
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:
```xml
app:debounceDuration="150"
```
Or you can set it programmatically.
```java
colorPickerView.setDebounceDuration(150);
```
### Create using builder
You can create an instance of `ColorPickerView` using `ColorPickerView.Builder` class like the example below:
```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();
```
### 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.
```gradle
app:initialColor="@color/colorPrimary"
```
Or you can use this method programmatically.
```java
.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.
```java
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.
```java
colorPickerView.setLifecycleOwner(this);
```
Or you can save the states manually using the method below:
```java
ColorPickerPreferenceManager.getInstance(this).saveColorPickerData(colorPickerView);
```
### Manipulate and clear
You 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 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:
```gradle
```
The codes below will start the Gallery and you can choose any desired images:
```java
Intent photoPickerIntent = new Intent(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.
```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();
}
```
## AlphaSlideBar
`AlphaSlideBar` adjusts the transparency value of the selected color.
`AlphaSlideBar` in XML layout
```gradle
// sets a size of the border.
```
You can attach and connect the `AlphaSlideBar` to your `ColorPickerView` using the `attachAlphaSlider` method.
```java
AlphaSlideBar alphaSlideBar = 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.
```gradle
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
```gradle
// sets a size of the border.
```
You can attach and connect the `BrightnessSlideBar` to your `ColorPickerView` using `attachBrightnessSlider` method.
```java
BrightnessSlideBar brightnessSlideBar = 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.
```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();
```
You can get an instance of `ColorPickerView` from the `ColorPickerView.Builder` and customize it by your preferences.
```java
ColorPickerView colorPickerView = builder.getColorPickerView();
colorPickerView.setFlagView(new CustomFlag(this, R.layout.layout_flag)); // sets a custom flagView
builder.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](https://github.com/skydoves/ColorPickerView#colorpickerview).
Here is an example code for displaying a bubble flag view, which indicates what color value was selected.
```java
BubbleFlag bubbleFlag = new BubbleFlag(this);
bubbleFlag.setFlagMode(FlagMode.FADE);
colorPickerView.setFlagView(bubbleFlag);
```
You can also fully customize the `FlagView` like the example below:
First, create a custom XML layout like the example below:
```gradle
```
Next, you should create a class that extends `FlagView`:
```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());
}
}
```
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:
```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
```
