I am creating an app where if the user leaves the app by any means and returns, I would like all the EditText fields cleared.
I have created some code that I thought would work which is:
@Override
public void onResume {
super.onResume;
(E开发者_JS百科ditText)findViewById(R.id.NumberEntry).setText("");
(EditText)findViewById(R.in.NameEntry).setText("");
}
However when I click on the Help menu (done through onMenuItemSelected()
) and ask for help the app gets the help file and gets it ready to draw but then crashes. I can't figure out why. Any advice would be appreciated.
Or if anyone has another method that will work.
Thanks
I'm not familiar with R.in, did you mean to type R.id.NameEntry?
@Override
public void onResume {
super.onResume;
(EditText)findViewById(R.id.NumberEntry).setText("");
(EditText)findViewById(R.id.NameEntry).setText("");
}
In addition to the typo theisenp said, you may need to cast the views to EditText's before calling setText --
@Override
public void onResume {
super.onResume;
((EditText)findViewById(R.id.NumberEntry)).setText("");
((EditText)findViewById(R.id.NameEntry)).setText("");
}
Notice the extra set of parenthesis.
