can not disable the view

[yikuo123]

the method "setEnabled" does not work, is there any way to disable it?

+1 I don't know how to disable it, would be useful to know.

Edit: I did a workaround. Put all the views in a custom view container. Override the onInterceptTouchEvent method and return true if the color picker is disabled, false otherwise.

Now when you want to disable the picker, use setEnabled on the picker (and setAlpha on the custom view container too if you want).

public class ColorPickerLinearLayout extends LinearLayout
{
    public interface OnInterceptTouchEventListener
    {
        boolean onInterceptTouchEvent(MotionEvent event);
    }

    private OnInterceptTouchEventListener mInterceptTouchEventListener;

    public ColorPickerLinearLayout(Context context)
    {
        this(context, null);
    }

    public ColorPickerLinearLayout(Context context, AttributeSet attrs)
    {
        this(context, attrs, 0);
    }

    public ColorPickerLinearLayout(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
    }

    public void setOnInterceptTouchEventListener(OnInterceptTouchEventListener interceptTouchEventListener)
    {
        mInterceptTouchEventListener = interceptTouchEventListener;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event)
    {
        if (mInterceptTouchEventListener != null)
        {
            return mInterceptTouchEventListener.onInterceptTouchEvent(event);
        }

        return false;
    }
}

To use it:

mColorPickerLayout.setOnInterceptTouchEventListener(new ColorPickerLinearLayout.OnInterceptTouchEventListener()
{
    @Override
    public boolean onInterceptTouchEvent(MotionEvent event)
    {
        //Don't pass on the touch event if we're disabled
        return !mColorPicker.isEnabled();
    }
});

//Enable
mColorPicker.setEnabled(true);
mColorPickerLayout.setAlpha(1.0f);

//Disable
mColorPicker.setEnabled(false);
mColorPickerLayout.setAlpha(0.3f);
