how to disable the power button of an activated button?

first you need to create two backgrounds disabled.xml and enabled.xml here is a website to help you do that http://angrytools.com/android/button/ put them in a folder / folder

here's how to show the button as disabled.

 button.setBackgroundResource(R.drawable.disabled);

to show it as included

 button.setBackgroundResource(R.drawable.enabled);

add a boolean variable that allows us to know the state of the button



boolean disabled=true ;//if the button is disabled at first

and then when you enable the button, change the background and boolean value

disabled=false;
button.setBackgroundResource(android.R.enabled);

and when you turn it off

disabled=true;
button.setBackgroundResource(android.R.disabled);

how to use: add this to the click listener button

  if(disabled){
 Toast.makeText(this,"Button disabled",Toast.LENGTH_SHORT).show();
}else {
//do what you want when button is enabled
}

My Solution involves creating two buttons.

A on a button that looks good and normal and has a normal click

An off button that looks like a power button but is off and off on. Click.

Do both of these dynamically with java in activity and then switch them to container layout in XML file at runtime.
