Android ImageButton setColorFilter Not Working

Question

I've look for posts that answer this issue, but none of them are working for me, so I think I have a fundamental misunderstanding of just how it's supposed to work. I have an ImageButton which has a png file applied to it. The png is mostly transparent with the exception of a white arrow. I want to tint the arrow red with setColorFilter: ``` imageButton.setColorFilter(Color.argb(255, 225, 0, 0)); ``` but this has no affect. I've tried the version of setColorFilter with various Porter-Duff modes, but none of those worked either. Any ideas on what the problem could be or what I might be missing would be greatly appreciated.

Accepted Answer

You have to get the Drawable from the button since the setColorFilter you are trying to use (in your setup) apply to those.

```
ImageButton btn = (ImageButton) myLayout.findViewByID(R.id.my_button);

int mycolor = getResources().getColor(R.color.best_color);

btn.getDrawable().setColorFilter(mycolor, PorterDuff.Mode.SRC_ATOP);
```

As long as you have the correct reference to a Drawable object,

`e.g. textView.getCompoundDrawables()[2].setColorFilter(...);`

which in its xml:

```
<TextView
...
android:drawableLeft="..." 
...
 />
```

you can use myDrawableObject.setColorFilter() to your full liking.

Edit:

For ImageButton, the drawable for `imageButton.getDrawable()` correspond to `android:src="..."` while `imageButton.getBackground()` correspond to the `android:background="..."` property. Make sure you call setColorFilter on the correct drawable.
