Android - Listen to a disabled button

Question

How can I respond to an event based on clicking a disabled Button. I have a requirement that I have to present Dialog, when a disabled Button is clicked but the listener I have assigned does not fire even when I setClickable(false)

Am an android noob, sorry.

You can for example use #setActivated() method instead. Disabling a view will ignore all events. https://developer.android.com/reference/android/view/View.html#setActivated(boolean). Then you can customize text and background styles with android:state_activate attribute if you need:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_activated="false"
      android:color="@color/a_color" />
    <item android:state_activated="true"
      android:color="@color/another_color" />
</selector>

That's a pretty good alternative. Should be higher up, or even the accepted answer, imho. – Levite Mar 15 '19 at 11:44

You can override onTouchEvent and create a listener like this :

class MyButton @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = R.attr.materialButtonStyle) : MaterialButton(context, attrs, defStyleAttr) {

    private var onDisableClickListener: OnClickListener? = null

    override fun onTouchEvent(event: MotionEvent?): Boolean {
        if (!isEnabled && event?.action == MotionEvent.ACTION_DOWN) {
            onDisableClickListener?.onClick(this)
        }
        return super.onTouchEvent(event)
    }

    fun setOnDisableClickListener(l: OnClickListener?) {
        onDisableClickListener = l
    }
}

In your activity :

button.setOnDisableClickListener {
            Toast.makeText(this), "The button is disabled", Toast.LENGTH_SHORT).show()
}
button.setOnClickListener {
            Toast.makeText(this), "The button is enabled", Toast.LENGTH_SHORT).show()
}

A disabled button cannot listen to any event, but you can customize your own button by extending Button class to make your own definition of disabling

Even though this is the accepted answer, it isn't particularly useful. :-( – David Wasser Dec 28 '16 at 11:14

Instead of disabling it, keep it enabled but use a flag to control your "inner state"

Could you (or someone) expand on this please? – marienke May 22 '17 at 09:21
no need to add a new flag when you can use buttons very own setActivated() method and then check with isActivated() – philtz Feb 19 '20 at 23:01

I solved this issue by using a flag to keep my button's state.

private boolean isMyButtonEnabled = false;

public void onMyButtonClick(View v) {
   if(isMyButtonEnabled){
      ..
   }
}

you can add android:allowClickWhenDisabled attribute to your button in xml like this:

<Button
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:allowClickWhenDisabled="true"/>

I looked for it but got nothing to listen the EditText block. So I find another way to activate it. If there is a near button or area that you already listen, you can enable SetOnLongClickListener to activate the block. It will be a secret but you can tell the users.

button.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            editText.setEnabled(true)
            return true;
        }
    });

enter image description here

I'm about to tackle this by using the selected state, which is generally available for use in widgets, and can be used in state list drawables. A simple search for usage of isSelected turns up results in ListView, GridView, TextView and TabLayout. And the documentation states

Views are typically * selected in the context of an AdapterView like ListView or GridView; * the selected view is the view that is highlighted.

You should use activated state to enable or disable button . It is clickable or as someone point use selected or checked state. Each of these state has a different meaning so use it carefully

create in res/color/color_state.xml

  <selector xmlns:android="http://schemas.android.com/apk/res/android">
     <item android:color="#767C7F" android:state_activated="true" />
     <item android:color="#CBCBCB" android:state_activated="false" />
     <item android:color="#CBCBCB" />
  </selector>

set textColor by:

   android:textColor="@color/color_state"

set event click to change state color:

   binding.format1.setOnClickListener {
        binding.format1.isActivated = true
        binding.format2.isActivated = false
        binding.format3.isActivated = false
    }
