Simple vertical and horizontal color picker

Usage

Add view to your activity's layout and specify orientation:

   <uz.shift.colorpicker.LineColorPicker
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/picker"
        android:layout_width="match_parent"
        android:layout_height="60dp"
        app:orientation="horizontal"/>

Optionally you can set colors directly in layout file:

        app:colors="@array/sample_colors"
        app:selectedColorIndex="3"

Setup view

colorPicker = (LineColorPicker) findViewById(R.id.picker);

// set color palette
colorPicker.setColors(new int[] {Color.RED,Color.GREEN,Color.BLUE,Color.YELLOW});

// set selected color [optional]
colorPicker.setSelectedColor(Color.RED);

// set on change listener
colorPicker.setOnColorChangedListener(new OnColorChangedListener() {
			@Override
			public void onColorChanged(int c) {
				Log.d(TAG, "Selected color " + Integer.toHexString(c));
			}
		});

// get selected color
int color = colorPicker.getColor();
