ColorPicker and ColorView

Question

So I got this button and this ColorView on my .xml layout as you see in the left snapshoot, I want to fill the background of the ColorView square with the color chosen by the user in the dialog that you see on the right snapshoot.

My .xml code:

 <Button android:id="@+id/color_button" style="@style/buttonStyle" android:layout_width="280sp" android:layout_height="wrap_content" android:layout_alignBottom="@+id/color_view" android:layout_alignParentStart="true" android:layout_marginStart="13dp" android:onClick="showColorPickerDialog" android:text="Color" /> <es.lost2found.lost2foundUI.pickerUI.ColorView android:id="@+id/color_view" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentEnd="true" android:layout_centerVertical="true" android:layout_marginEnd="18dp" android:background="@color/otherUserMsgColor"> </es.lost2found.lost2foundUI.pickerUI.ColorView>

The onClick method called on the button is this one:

public void showColorPickerDialog(View v) { ColorPickerUI colorpicker = new ColorPickerUI(); colorpicker.build() .title(R.string.color_dialog_title) .colorPreset(Color.BLACK) .allowCustom(true) .show(this, "dialog"); }

I'm using the QuadFlask ColorPicker, I don't know if there's a method to do what I want, I've been searching on the repository and I didn't find it.

If there's any way to get what I want with other colorPicker let me know please, any help will be apreciated!

You need to add listener , which will be triggered when a color is either selected or positive button is pressed so use it like

public void showColorPickerDialog(View v) { ColorPickerUI colorpicker = new ColorPickerUI(); colorpicker .title(R.string.color_dialog_title) .colorPreset(Color.BLACK) .allowCustom(true)// change color on continuous selection .addOnColorChangedListener(new OnColorChangedListener() { @Override public void onColorChanged(int selectedColor) { findViewById(R.id.color_button).setBackgroundColor(selectedColor); } })// change color on selection .addOnColorSelectedListener( new OnColorSelectedListener() { @Override public void onColorSelected(int selectedColor) { findViewById(R.id.color_button).setBackgroundColor(selectedColor); } }) .build().show(this, "dialog"); }

I get an error on setPositiveButton "Cannot resolve method setPositiveButton(java.lang.String, anonymous com.flask.colorpicker.builder.ColorPickerClickListener)"

finally I got it, I've used onColorSet() method on my ColorPicker class, I put here the code in case someone need it

View view = getActivity().findViewById(R.id.color_view); view.setBackgroundColor(mSelectedColor);

All I have to do was use the variable mSelectedColor and setBackground with it. Thank you so much to @Pavneet_Singh for your help, I'm sure someone will use your code!

I didn't know that you are using it in a fragment but glad that you found the solution
