How to reset the style of an edittext?

Question

I have an edit text which I validate. If the data entered does not corespond to the format, I set the background to red, when it coresponds I set it back to light gray, but the rectangle disappears. I was wondering if I could reset it's properties to their orignal values when the data entered has the correct format. This is what i am doing now

EditText name = (EditText) findViewById(R.id.Name);
if (name.getText().length() < 1)
{
    error = true;
    unit.setBackgroundColor(Color.RED);
}
else
{
    //instead of this line reset edittext properties
    unit.setBackgroundColor(Color.LTGRAY);
}

What exactly do you mean with "the reactangle disappears"? So when setting it to RED all is fine but when setting it to LTGRAY the border around the box disappears? — randomizer, May 30 '13 at 08:01

You can use PorterDuff instead - it has a clear method: http://developer.android.com/reference/android/graphics/PorterDuff.Mode.html.

To set the color:

name.getBackground().setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);

To remove the color:

name.getBackground().clearColorFilter();

You can try:

editText.setText("");

i want to reset the layout not the text, reverting the background to it's original style – Liviu May 30 '13 at 07:59
Okay, final Drawable oldBackground = activity.findViewById(id).getBackground();if(correct){ text.setBackgroundDrawable(oldBackground);} – SamDroid May 30 '13 at 08:01
the border still disappears – Liviu May 30 '13 at 08:10
the only thing (i think) to do is to draw the border – SamDroid May 30 '13 at 08:13

I'd recommend using the setError() method, which displays an error message above the EditText and removes it automatically when the contents of the EditText change. This is a standard way to show the user that the validation has failed.

You are changing the EditText background so you are overriding android's default background.
you need to manually change it to some other background.
you can save it by Using the getBackground() method in EditText.

You can save the status of the editText before to change it, and restore when you need:

private Drawable originalDrawable;

EditText name = (EditText) findViewById(R.id.Name);
if (name.getText().length() < 1) {
    if (originalDrawable == null) {
        originalDrawable = unit.getBackground();
    }
    error = true;
    unit.setBackgroundColor(Color.RED);
}
else {
    //reset editText 
    text.setBackgroundDrawable(originalDrawable);
}
