Android Color Picker

sascha — Fri, 02 Dec 2011 09:14:30 +0000

This Android tutorial shows a color picker which we developed for our Android App City, Country, Caller ID. The source code can be downloaded as Eclipse project: Android Color Picker.

Here we have, in the first example, a predefined list with colors:

We use a GridView with six columns. Within the rows and columns there is an ImageView defined, which background color will be set using imageView.setBackgroundColor(colorList.get(position));.

The layout of the GridView is defined in res/layout/color_picker.xml.

Look for the colors in ColorPickerAdapter.java, which are placed in an array (for better reading).

// for convenience and better reading, we place the colors in a two dimension array
String colors[][] = { { "822111", "AC2B16", "CC3A21", "E66550", "EFA093", "F6C5BE" },
		{ "A46A21", "CF8933", "EAA041", "FFBC6B", "FFD6A2", "FFE6C7" },
		{ "AA8831", "D5AE49", "F2C960", "FCDA83", "FCE8B3", "FEF1D1" },
		{ "076239", "0B804B", "149E60", "44B984", "89D3B2", "B9E4D0" },
		{ "1A764D", "2A9C68", "3DC789", "68DFA9", "A0EAC9", "C6F3DE" },
		{ "1C4587", "285BAC", "3C78D8", "6D9EEB", "A4C2F4", "C9DAF8" },
		{ "41236D", "653E9B", "8E63CE", "B694E8", "D0BCF1", "E4D7F5" },
		{ "83334C", "B65775", "E07798", "F7A7C0", "FBC8D9", "FCDEE8" },
		{ "000000", "434343", "666666", "999999", "CCCCCC", "EFEFEF" } };
 
colorList = new ArrayList();
 
// add the color array to the list
for (int i = 0; i &lt; colors.length; i++) {
	for (int j = 0; j &lt; colors[i].length; j++) {
		colorList.add(Color.parseColor("#" + colors[i][j]));
	}
}

In the next step we will assign the Adapter to the GridView:

GridView gridViewColors = (GridView) findViewById(R.id.gridViewColors);
gridViewColors.setAdapter(new ColorPickerAdapter(getContext()));

The second example shows a Rainbow-Color-Picker where the number of colors is flexible:

Define the rainbow with the following steps::

// FF 00 00 --> FF FF 00
for (red = 255, green = 0, blue = 0; green &lt;= 255; green += step)
    colorList.add(Color.rgb(red, green, blue));
 
// FF FF 00 --> 00 FF 00
for (red = 255, green = 255, blue = 0; red &gt;= 0; red -= step)
    colorList.add(Color.rgb(red, green, blue));
 
// 00 FF 00 --> 00 FF FF
for (red = 0, green = 255, blue = 0; blue &lt;= 255; blue += step)
    colorList.add(Color.rgb(red, green, blue));
 
// 00 FF FF -- > 00 00 FF
for (red = 0, green = 255, blue = 255; green &gt;= 0; green -= step)
    colorList.add(Color.rgb(red, green, blue));
 
// 00 00 FF --> FF 00 FF
for (red = 0, green = 0, blue = 255; red &lt;= 255; red += step)
    colorList.add(Color.rgb(red, green, blue));
 
// FF 00 FF -- > FF 00 00
for (red = 255, green = 0, blue = 255; blue &gt;= 0; blue -= 256 / step)
    colorList.add(Color.rgb(red, green, blue));

Layout tipps

Right now the layout is only optimized for hdpi devices. Looking at a ldpi device (small screen) we get the following screen:

We have to adjust the GridView column width in order to have the desired layout on various screens. Creating the file res\values-small\strings.xml and setting the width with colorGridColumnWidth will solve the problem:
