How to grey out a button?

Question

I have a button defined as shown below. When I want to disable it I use my_btn.setEnabled(false), but I would also like to grey it out. How can I do that?

Answer 1

I tried the above solutions but none of them seemed to work for me. I went with the following option:

<!-- button_color_selector.xml -->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/colorAccent" android:state_enabled="true"/>
    <item android:color="@color/colorAccentLight" android:state_enabled="false"/>
</selector>

<com.google.android.material.button.MaterialButton
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:backgroundTint="@color/button_color_selector"
                .../>

Answer 2

Set Clickable as false and change the backgroung color as:

callButton.setClickable(false);
callButton.setBackgroundColor(Color.parseColor("#808080"));

Answer 3

You have to provide 3 or 4 states in your btn_defaut.xml as a selector.

1. Pressed state
2. Default state
3. Focus state
4. Enabled state (Disable state with false indication; see comments)

You will provide effect and background for the states accordingly.
