Converting a string to an integer on Android


How do I convert a string into an integer?

I have a textbox I have the user enter a number into:

EditText et = (EditText) findViewById(R.id.entry1);
String hello = et.getText().toString();

And the value is assigned to the string hello.

I want to convert it to a integer so I can get the number they typed; it will be used later on in code.

Is there a way to get the EditText to a integer? That would skip the middle man. If not, string to integer will be just fine.


Solution

  • See the Integer class and the static parseInt() method:

    http://developer.android.com/reference/java/lang/Integer.html

    Integer.parseInt(et.getText().toString());
    

    You will need to catch NumberFormatException though in case of problems whilst parsing, so:

    int myNum = 0;
    
    try {
        myNum = Integer.parseInt(et.getText().toString());
    } catch(NumberFormatException nfe) {
       System.out.println("Could not parse " + nfe);
    }
