Convert hex color value ( #ffffff ) to integer value

Question

I am receiving hex color values from a server (in this form, #xxxxxx , example #000000 for black)

How do I convert this to an integer value

Answer 1

Based on CQM's answer and on ovokerie-ogbeta's answer to another question I've come up with this solution:

if (colorAsString.length() == 4) { // #XXX
    colorAsString = colorAsString.replaceAll("#([0-9a-fA-F])([0-9a-fA-F])([0-9a-fA-F])", "#$1$1$2$2$3$3");
}

int color = Color.parseColor(colorAsString);

Answer 2

Try this, create drawable in your resource...

<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="@color/white"/>
    <size android:height="20dp"
        android:width="20dp"/>
</shape>

then use...

 Drawable mDrawable = getActivity().getResources().getDrawable(R.drawable.bg_rectangle_multicolor);
mDrawable.setColorFilter(Color.parseColor(color), PorterDuff.Mode.SRC_IN);
mView1.setBackground(mDrawable);

with color... "#FFFFFF"

if the color is transparent use... setAlpha

mView1.setAlpha(x); with x float 0-1 Ej (0.9f)

Good Luck

Answer 3

The real answer is to use:

Color.parseColor(myPassedColor) in Android, myPassedColor being the hex value like #000 or #000000 or #00000000.

However, this function does not support shorthand hex values such as #000.
