我试过这个片段,但它不起作用

try 
    {
    Integer.parseInt(enteredID.getText().toString());
    Log.i("enteredID value", "enterdID is numeric!!!!!!!!!!!^^^");
    flag=1;
} catch (NumberFormatException e) {
    flag=-1;
    Log.i("enteredID value", "enterdID isn't numeric!!!!!!!!!!!^^^");
}

注意它可以接受用户名或ID来检查值,我不希望它只接受数字!
