How to set custom background color while item is touched?

Question

I basically want to customize list item`s background color while it is touched. I tired writing a listener but it seams that I made some kind of mistake or misunderstood the concept of these actions.

v.setOnTouchListener( new TextView.OnTouchListener() {

    public boolean onTouch(View v, MotionEvent event) {
            switch(event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                v.setBackgroundColor(Color.RED); 
                    break;
            case MotionEvent.ACTION_UP:
                v.setBackgroundColor(Color.WHITE);
                break;
            }

    return false;
    }
}
);

Default color is light blue. I want to change it for every list item. This code changes items color to red when touched but it does not change back after that.

You should return true as written here: http://stackoverflow.com/a/27739621/2914140. — CoolMind, Oct 20 '15 at 12:59

But maybe the best would be to use color states...create a file mycolors.xml in the color folder with this:

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_pressed="true"
              android:color="#ff0000"/> <!-- pressed -->
        <item android:color="#ffffff"/> <!-- default -->
    </selector>

then later you set the background of the view like this: android:background="@color/mycolors" in the layout xml or programmatically like this: v.setBackgroundColor(getResources().getColor(R.color.mycolors);

no clicks or touch listeners will be necessary in this case..everything will happen magically.

`android:background="@color/mycolors"` didn't work for me! it causes an exception when inflating layout. — Alireza Mirian, Mar 31 '14 at 02:41
@AlirezaMirian that's because `android:color` should actually be `android:drawable` in this case. — Jon Cairns, Jul 21 '15 at 08:38

Did you try to catch ACTION_CANCEL too?

So...

...
case MotionEvent.ACTION_CANCEL:
case MotionEvent.ACTION_UP:
    v.setBackgroundColor(Color.WHITE);
     break;
...

I think the ListView is intecepting the touch event because it starts to scroll. So you never get an up-action but a cancel-action (I assume).

use a statelistdrawable. you can find examples all over, including the Android developer site.

The key point is that you can create a StateListDrawable programmaticaly with `StateListDrawable states = new StateListDrawable(); states.addState(new int[] {android.R.attr.state_pressed}, new ColorDrawable(color));` – Sylphe Jan 30 '14 at 10:32
