How do I return an int from EditText? (Android)

Basically, I want an EditText in Android where I can have an integer value entered into. Perhaps there is a more appropriate object than EditText for this?

Set the digits attribute to true, which will cause it to only allow number inputs.

Then do Integer.valueOf(editText.getText()) to get an int value out.

For now, use an EditText. Use android:inputType="number" to force it to be numeric. Convert the resulting string into an integer (e.g., Integer.parseInt(myEditText.getText().toString())).

In the future, you might consider a NumberPicker widget, once that becomes available (slated to be in Honeycomb).

First of all get a string from an EDITTEXT and then convert this string into integer like

      String no=myTxt.getText().toString();       //this will get a string                               
      int no2=Integer.parseInt(no);              //this will get a no from the string

You can do this in 2 ways:

1: Change the input type(In your EditText field) in the layout file to android:inputType="number"

Or

2: Use int a = Integer.parseInt(yourEditTextObject.getText().toString());
