Set Thump Position about hsv-alpha-color-picker-android HOT 4 CLOSED

I'm not sure what you mean by "thump". What exactly are you trying to do?

from hsv-alpha-color-picker-android.

I'm talking about the circle shaped object that changes ValueView and AlphaView when scrolled right or left. By default, I get 100% transparent AlphaView color unless I slide it to the other side for example. I'm trying to get 0% transparent color when I start the activity, then I get the option to increase the transparency.

in XML I tried to set the progress to 100 and 50 but nothing happened, I still get full transparency:
The mover doesn't change its position.

<com.rarepebble.colorpicker.AlphaView
        android:progress="50"
        android:id="@+id/alphaView"
        android:layout_width="match_parent"
        android:layout_height="@dimen/sliderWidth"
        android:layout_marginBottom="@dimen/margin"
        />

The positions of the circles are determined by the color that you set. If you want to start with a particular transparency, then set the color with that transparency with ColorPickerView.setColor:

Or in the preferences.xml with defaultValue:

The alpha view does not understand any XML configuration on its own. Only the ColorPickerView and the ColorPreference do anything with XML.

That worked just great. I had to make a few changes in my code. I appreciate your hardworking.
Keep it up :)
