chiralcode / android-color-picker Goto Github PK

I am testing with the one color picker wich I included into the xml file like:
<com.chiralcode.colorpicker.ColorPicker
android:id="@+id/colorPicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

I removed the outer circle because I want to control the brightness with an seekbar.
It is working nicely but there is one problem.
If i want to set the color to one color that is shown near the border (every color with full saturation) the "picker" often dont get to the border of the color circle.
Is there a way how I can make the "picker" follow my finger on the closest position in the circle even If I left the circle?
I mean: If I chose white and slide to the left side of the circle (where red is) and stay with the finger on the screen, then moving outside the circle and slide outside the circle to the right side (where azur blue is). Is there a way to let the "picker" follow my finger on the color closest to the position of my finger?

Thank you a lot!

when ColorPickerDialog is visible and screen is rotated, older view is not cleared and new view is drawn. and the final view is corrupted

Your code was used as base for the color picker of this game:
https://github.com/dftec-es/planetcon/tree/master/src/com/dftec/planetcon/settings
I just wanted to thank you for sharing it.

Originally, I wanted to fork the project and create a pull request. Since there were unstaged files directly from the beginning (after git pull from my work), I will write the change here. I added a preview to the ColorPickerPreference, where the color will be drawn in a Rectangle on the right side of the category.

Simply add this stuff to the ColorPickerPreference class:

private LinearLayout preview;

@Override
protected View onCreateView(ViewGroup parent) {
    final LinearLayout view = (LinearLayout) super.onCreateView(parent);

    preview = new LinearLayout(getContext());
    preview.setLayoutParams(new LinearLayout.LayoutParams(60, 60));
    preview.setBackgroundColor(selectedColor);
    preview.invalidate();

    view.addView(preview);

    return view;
}

Overrite the onDialogClosed function with:

@Override
protected void onDialogClosed(boolean positiveResult) {
    if (positiveResult && shouldPersist()) {
        if (callChangeListener(colorPickerView.getColor())) {
            selectedColor = colorPickerView.getColor();
            persistInt(selectedColor);
            preview.setBackgroundColor(selectedColor);
        }
    }
}

You may want to merge this, you may not. It's up to you. I just felt the need to share it, since I find it kinda nice to see the color in a little preview.

I want to set the position of cursor when first open picker

Is there a way to modify the color picker so that it continuously outputs a color value as it is changed? Similar to the function onProgressChanged that a seekBar uses.

can you release a new version of this project to use it easily in android studio 👍 ?

It works in linearlayout, but when I ad it to ScrollView my app crashes.

Is there a way to hide the alpha bar?

Hi, In your preview you used java code to show how to get the selected color. I am using c# with Xamarin.Android. Can you give me an example of how I can get the selected color? I can't figure it out!?
