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

Answer 1

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

Answer 2

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.

Answer 3

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

Answer 4

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;
        }
    });

Answer 5

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

Answer 6

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 (event?.action == MotionEvent.ACTION_DOWN && !isEnabled) {
            onDisableOnClickListener?.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()
}
