Improve this question

I am looking for a Color Picker framework which can return color HEX on selection.

I have looked at this wondering if there is some other library I can use.

I know the question is old, but if someone is looking for a great new android color picker that use material design I have forked an great project from github and made a simple-to-use android color picker dialog.

This is the project: Android Color Picker

Android Color Picker dialog

Android Color Picker [closed]

HOW TO USE IT

Adding the library to your project

The aar artifact is available at the jcenter repository. Declare the repository and the dependency in your build.gradle.

(root)

repositories {
    jcenter()
}

(module)

dependencies {
    compile 'com.pes.materialcolorpicker:library:1.0.2'
}

Use the library

Create a color picker dialog object

final ColorPicker cp = new ColorPicker(MainActivity.this, defaultColorR, defaultColorG, defaultColorB);

defaultColorR, defaultColorG, defaultColorB are 3 integer ( value 0-255) for the initialization of the color picker with your custom color value. If you don't want to start with a color set them to 0 or use only the first argument

Then show the dialog (when & where you want) and save the selected color

/* Show color picker dialog */
cp.show();

/* On Click listener for the dialog, when the user select the color */
Button okColor = (Button)cp.findViewById(R.id.okColorButton);

okColor.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
            
        /* You can get single channel (value 0-255) */
        selectedColorR = cp.getRed();
        selectedColorG = cp.getGreen();
        selectedColorB = cp.getBlue();
            
        /* Or the android RGB Color (see the android Color class reference) */
        selectedColorRGB = cp.getColor();

        cp.dismiss();
    }
});

That's all :)

You can use the following code, it will give you same look as http://code.google.com/p/color-picker-view/

I ended up here looking for a HSV color picker that offered transparency and copy/paste of the hex value. None of the existing answers met those needs, so here's the library I ended up writing:

HSV-Alpha Color Picker for Android (GitHub).

HSV-Alpha Color Picker Demo (Google Play).

I hope it's useful for somebody else.

Android Color Picker [closed]

We have just uploaded AmbilWarna color picker to Maven:

https://github.com/yukuku/ambilwarna

It can be used either as a dialog or as a Preference entry.

Android Color Picker [closed]

If you want a fragment solution, I have made a fork of android-color-picker where DialogFragment is used and is re-created on configuration change. Here's the link: https://github.com/lomza/android-color-picker

Here's another library:
https://github.com/eltos/SimpleDialogFragments

Features color wheel and pallet picker dialogs

Android Color Picker [closed]

Usage for HSV Color picker:

Add the library from maven and in your code just call:

SimpleColorWheelDialog.build()
                      .color(0xFFCF4747) // optional initial color
                      .alpha(true)
                      .show(Activity.this, COLOR_PICKER);

and to get the results let the Activity or fragment implement OnDialogResultListener:

@Override
public boolean onResult(@NonNull String dialogTag, int which, @NonNull Bundle extras) {
    if (COLOR_PICKER.equals(dialogTag) && which == BUTTON_POSITIVE){
        int color = extras.getInt(SimpleColorWheelDialog.COLOR);
        // ...
        return true;
    }
    return false;
}

After some searches in the android references, the newcomer QuadFlask Color Picker seems to be a technically and aesthetically good choice. Also it has Transparency slider and supports HEX coded colors.
