Disable back button in android

Question

How to disable back button in android while logging out the application?

Answer 1

Just override the onBackPressed() method and no need to call the super class of onBackPressed method or others..

@Override
public void onBackPressed()
{

}

Or pass your current activity into the onBackPressed() method.

@Override
public void onBackPressed()
{
   startActivity(new Intent(this, myActivity.class));  
   finish();
}

Replace your require activity name to myActivity.

if you are using fragment then first of all call the callParentMethod() method

public void callParentMethod(){
    context.onBackPressed(); // instead of context use getActivity or something related
}

then call the empty method

@Override
public void onBackPressed()
{

}
